Additional affordable housing provision: quality report

Additional affordable housing statistics provide summary information on the number of additional affordable housing units delivered across Wales during the year. The figures cover all additional affordable housing units, whether through new build, purchase, acquisition, leasing or conversion of existing dwellings. They do not take account of any loss of affordable housing stock through demolitions or sales during the year.

As well as the detailed analysis shown within this annual release, data at an individual local authority and National Park level are published on StatsWales.

Affordable housing applies to housing where there are secure mechanisms in place to ensure that it is accessible to those who cannot afford market housing, both on first occupation and for subsequent occupiers as defined in Technical Advice Note (TAN) 2: Planning and Affordable Housing (2006).

Affordable housing includes social rented housing that is provided by local authorities and registered social landlords as well as intermediate housing where prices or rents are above those of social rent but below market housing prices or rents. Figures include additional affordable housing units provided under schemes which may provide for stair-casing to full ownership as long as there are secure arrangements in place to ensure the recycling of capital receipts to provide replacement affordable housing.

The additional affordable housing figures also include housing units leased for more than one year to provide accommodation for homeless families. These units do not fully meet the TAN 2 definition in relation to the subsequent occupation once the lease has expired.

The additional affordable housing figures include any units that have been specifically delivered through planning obligations (section 106 agreements) or planning conditions either as a part of or as a result of market housing developments. The number of affordable homes provided on a particular site will be determined by the local authority’s planning policy and negotiations with the developer. The agreed affordable housing contribution will be secured via a section 106 agreement which is a legally binding contract between a developer and a local planning authority that operates alongside a planning permission.

The data collection was originally introduced to monitor the progress made towards the target to increase the supply of affordable homes in Wales by 6,500 by 2011 as set out in ‘One Wales’ the previous government strategy.

Commitment to deliver 20,000 new low-carbon homes for rent in the social sector during 2021 to 2026

In June 2021, Welsh Government announced the commitment to deliver 20,000 new low-carbon homes for rent in the social sector as part of the 2021 to 2026 Programme for Government.

The 20,000 homes target definition for the current government term differs to the target for the previous government term (2016 to 2021) – for example, excluding homes delivered through the Help to Buy-Wales and the Rent to Own schemes but including void social housing units brought back into use through Transitional Accommodation Capital Funding (TACP).

Progress towards achieving the commitment is included in the statistical release.

To measure progress, we include homes for social rent, intermediate rent and shared ownership units. These units are delivered by registered social landlord, local authorities, and private sector providers (referred to as ‘others’). The figures also include housing units leased for more than one year to provide accommodation for homeless families, although these units do not fully meet the TAN 2 definition. The reported target figure excludes shared equity affordable units.

Whilst the data collected doesn’t specifically capture information on carbon levels, all homes that count toward the target are required to meet specific standards including energy efficiency. 

New build homes and conversions of existing buildings in receipt of grant are required to meet the relevant standards for their time, currently the Welsh Development Quality Requirements (WDQR) 2021. This requires social landlords to meet the standard of EPC A and not use fossil fuel fired boilers to provide domestic hot water and space heating. Homes are also required to be safe and secure and meet specific space standards. Homes started before that time, met the previous standard of Development Quality Requirements (DQR).  

For existing properties purchased either on the open market or new properties purchased directly from developers using grant funding, a hierarchical approach is taken to ensure compliance with housing standards. Properties must meet one of the following criteria.

1. WDQR 2021 at the point of purchase.
2. Welsh Housing Quality Standards 2023 (WHQS 2023) at the point of purchase.
3. Be capable of meeting either WHQR 2021 or WHQS 2023 within 10 years of purchase.
4. If the property cannot meet WHQS  2023 within 10 years, it can be purchased and used for a minimum of 5 years and a maximum of 10 years. After this time it must be sold on the open market with proceeds reinvested in social housing.  

WHQS 2023 includes requirements to ensure properties are affordable to heat and have minimal environmental impact. 

In May 2025, the Cabinet Secretary for Housing and Local Government accepted a recommendation from the Affordable Housing Taskforce that ’void’ social housing units funded by the Transitional Accommodation Capital Programme (TACP) should be treated the same as acquisitions and included within the 20,000 target. 

Following this decision, we have included voids delivered by TACP in our reporting against the target. The TACP started in 2022.

Previous target

In September 2016, the Welsh Government announced the Programme ‘Taking Wales Forward 2016 to 2021’ which included a commitment to work in partnership to deliver an extra 20,000 affordable homes during 2016 to 2021, including supporting construction of more than 6,000 homes through the Help to Buy scheme. Under the Help to Buy- Wales scheme, loans were available to buyers wishing to purchase a new-build property worth up to £300,000. 

In February 2018 the Welsh Government introduced two new schemes, Rent to Own – Wales and Shared Ownership – Wales, aimed at offering the opportunity of home ownership to households who can afford the monthly mortgage payments but do not have the level of deposit normally required to purchase a home.

Under Rent to Own – Wales, aspiring buyers will pay market rents for new-build homes from participating housing associations, and will have the option to purchase these from the end of the second year of their rental period. Upon exercising the option to purchase, the aspiring buyer will be gifted an amount equivalent to 25% of the rent they have paid and 50% of any increase in the value of the home, to use as a mortgage deposit. This will help them to purchase the home that they are renting. Information on affordable housing units delivered via the new Rent to Own scheme-Wales are not included in the total additional affordable housing figures shown within this release as they do not fully conform with the TAN 2 definition. The deadline for participating landlords to submit schemes to Rent to Own was 31 March 2021.

Shared Ownership - Wales is a part-buy, part-rent scheme suitable for aspiring buyers who have some deposit but are unable to obtain the level of mortgage to purchase the home outright. Aspiring buyers can purchase an initial share of 25% to 75% of the value of new-build homes, which are available for this scheme from participating housing associations. They can staircase up to full ownership at any time. Rent will be payable on the un-owned share. The number of additional affordable housing units delivered using the Shared Ownership - Wales scheme are included in the total additional affordable housing figures shown within this release as they do conform to the TAN 2 definition.

In August 2020, Welsh Government published estimates of additional housing need split by tenure (affordable and market), at a national and regional level. Separately, local authorities assess their own housing need through Local Housing Market Assessments (LHMAs). LHMAs provide evidence to inform a local authority’s Local Development Plan (LDP) process and Local Housing Strategies, as well as help inform their capital funding requirements. The process was developed to provide a consistent approach and basis for all local authorities.

This information is used to look at trends in the provision of additional affordable housing units over time. This information will be used alongside other information (including on Help to Buy) to monitor the progress made towards the current government’s target to deliver 20,000 new low-carbon homes for rent in the social sector as well as monitoring the commitments outlined in the ‘National Housing Strategy’.  

Local authorities and National Parks use the information to monitor local affordable housing delivery targets; develop their Local Housing Market Assessments; for effective cross-authority working on Affordable Housing issues and accurate benchmarking; for evidencing how housing demand is being met locally and for  assessing future requirement and need in order to plan and allocate resources effectively.

More generally the information is used for:

• monitoring housing trends
• policy development
• advice to ministers
• informing debate in the Senedd and beyond
• geographic profiling, comparisons and benchmarking

There is a variety of users of these statistics including national and local government, researchers, academics and students.

Strengths

• The information is processed and published frequently and in an ordered manner to enable users to see the statistics when they are current and of greatest interest.
• The data has undergone a thorough validation and quality assurance process.
• Outputs have a clear focus on Wales and have been developed to meet the internal and external user need in Wales.
• Detailed statistics are provided via our StatsWales website at local authority level.
• The ‘Planned’ data shown in this release is based on information provided by local authorities and covers all planned additions from all providers for their local authority area.

Limitations

• The information includes units leased to provide accommodation for homeless families where the lease extends over 1 year. These private sector units do not fully conform to the (TAN)2 definition in relation to the subsequent occupation once the lease has expired.
• Because of the devolved administrations and differing policy, there is less scope for direct UK comparisons (see ‘Coherence’ later in the document).

Data collection

The figures shown in this Statistical Release are based on information collected via annual statistical returns completed by local authorities, registered social landlords and National Park authorities in Wales. Prior to introduction of this data collection, data providers were involved in the development of both the forms and the guidance through attendance at three regional events. These events ensured that data providers fully understood the guidance and provided information on a consistent basis.

Local authorities, National Park authorities and registered social landlords are notified of the data collection exercise timetable in advance.  This allows adequate time for local authorities, National Park authorities and registered social landlords to collate their information, and to raise any issues they may have. There is guidance in the spreadsheet, which assists users when completing the forms. 

Copies of the current additional affordable housing data collection forms are available.

During 2024 to 2025, data were collected from the 22 local authorities (LAs), 3 national park authorities (NPAs) and all Welsh registered social landlords (RSLs), covering additional affordable housing across all tenures. Local authorities also provide data for private sector (‘other’) providers who have delivered units within their local authority area.

The data was collected to determine not only how many additional affordable homes were delivered during the 2024 to 2025 financial year, but also how many were planned for delivery in the 2025 to 2026 financial year. The ‘planned’ data shown in this release is based on information provided by local authorities and includes units planned by LAs, RSLs and ‘other’ providers.

The figures in this release are based on additional affordable housing units and do not take account of any reduction of affordable housing stock.

Additional affordable housing units delivered or planned include units leased to provide accommodation for homeless families where the lease extends over 1 year.

The data collection identified affordable homes/units provided through different tenures (social rented, intermediate rented and shared equity) as well as whether the units were delivered:

• with capital grant funding (e.g. Social Housing Grant [SHG], Vibrant and Viable Places, Welsh Housing Partnership (WHO) and the Housing Finance Grant (HFG)
• on affordable housing exception sites or through planning obligations (Section 106 agreements)
• on local authority and other public sector land
• inside or outside National Park areas

For the purposes of this data collection, housing provided through the following schemes and initiatives has been counted.

• General Needs including Homebuy
• Vulnerable Households and Extra Care
• Mortgage Rescue
• Section 106 New Build Units (committed and windfall)
• Affordable Housing Exception Site Policy (inc. Community Land Trusts [CLTs])
• Empty Homes initiatives
• Leasing Schemes (leases of more than one year)
• Shared Ownership – Wales

Additional affordable housing units are recorded as being delivered through planning obligations or on affordable housing exception sites, irrespective of when planning permission was granted. Those additional affordable housing units delivered or granted planning permission through planning obligations may or may not be on affordable housing exception sites.

From 2011-12 onwards local authorities were required to provide information on the number of additional affordable housing units which were delivered on land made available by other public sector bodies within the last five years as well as the number delivered on local authority land. The affordable units may or may not have been provided by means of a section 106 planning agreement. The land may have been sold at market value, at a discount, or transferred at nil cost. The other public sector bodies included are listed in the glossary section of this release.

Validation and verification

Individual local authorities and RSLs are responsible for providing high quality data. The Welsh Government data collection team are responsible for validating and undertaking reasonable checks on this data in order to ensure that the data meet the requirements for ‘national statistics’. The Welsh Government housing statistics team are responsible for the quality assurance of the analysis in the outputs.

The information is collected annually via Excel spreadsheets which are downloaded from the Objective Connect file transfer website which provides a secure method for users to submit data. There is guidance in the spreadsheet, which assists users on completing the form. The spreadsheets allow respondents to validate some data before sending the spreadsheet to the Welsh Government.

Examples of validation checks within the forms include cross checks with other relevant tables and checks to ensure data is logically consistent. Respondents are also given an opportunity to include contextual information where large changes have occurred (e.g. data items changing by more than 10% compared to the previous year). This enables some data cleansing at source and minimises follow up queries.

On receipt of the data collection forms, the data collection team carry out further validation and verification checks, for example:

• common sense check for any missing/incorrect data without any explanation
• arithmetic consistency checks
• cross checks against the data for the previous year
• cross checks with other relevant data collections
• thorough tolerance checks
• verification that data outside of tolerances is actually correct
• a series of validation steps to ensure that the data is correct and consistent

The data collection team work closely with the different types of data providers to ensure the information provided is accurate and on a consistent basis. They also check that the data is consistent with the number of new build units reported during the past year and resolve any queries with landlords. If there is a validation error, the local authority, national park authority or registered social landlord is contacted to seek resolution. If they do not receive a response within a reasonable timeframe, they apply imputation to improve data quality. They will inform the organisation and explain how the data has amended or imputed.

They compare data provided by local authorities and registered social landlords. Where there are discrepancies, they work with the data providers to align the figures. In a small number of cases, data providers are unable to reconcile their data within the publication timeframe. In these cases, they use the combined figures provided by registered social landlords, as well as any local authority and private developer activity, to make the final total for the local authority area. We ensure landlords are informed when this approach is taken. Additionally, local authorities, national parks authorities and Welsh RSLs also work together to ensure the accuracy of information provided.

In tables where figures have been rounded, the sum of the individual figures may not equal the total shown.

Publication

Once the data has been finalised, the release is compiled and key points and commentary are drafted. The release is independently checked and a final sense check is carried out by the relevant statistician prior to publication on the website.

Standards

The statistics that are prepared adhere to recognised professional standards. They are produced in accordance with the Code of Practice for Statistics independently under the responsibility of the Welsh Government Chief Statistician.

National Statistics status means that official statistics meet the highest standards of trustworthiness, quality and public value.

All official statistics should comply with all aspects of the Code of Practice for Statistics. They are awarded National Statistics status following an assessment by the UK Statistics Authority’s regulatory arm. The Authority considers whether the statistics meet the highest standards of Code compliance, including the value they add to public decisions and debate.

It is Welsh Government’s responsibility to maintain compliance with the standards expected of National Statistics. If we become concerned about whether these statistics are still meeting the appropriate standards, we will discuss any concerns with the Authority promptly. National Statistics status can be removed at any point when the highest standards are not maintained, and reinstated when standards are restored.

The continued designation of these statistics as National Statistics was confirmed in July 2019 following a compliance check by the Office for Statistics Regulation. Since the latest review by the Office for Statistics Regulation, we have continued to comply with the Code of Practice for Statistics, and have made the following improvements:

• within the quality report we have included more detail in relation to our knowledge of the quality assurance processes carried out by data providers and have also provided more detail in relation to overall responsibility for the quality management process
• added additional terms of the release glossary
• referenced the cross-government work on affordable housing
• we have enhanced trustworthiness by reviewing and reducing pre-release access

This release has been scored against the UK Statistics Authority Administrative Data Quality Assurance matrix. The matrix is the UK Statistics Authority regulatory standard for the quality assurance of administrative data. The Standard recognises the increasing role that administrative data are playing in the production of official statistics and clarifies what producers of official statistics should do to assure themselves of the quality of these data. The toolkit that supports it provides helpful guidance to statistical producers about the practices they can adopt to assure the quality of the data they receive, and sets out the standards for assessing statistics against the Code of Practice for Statistics.

How we have assessed this release

• Operational context and administrative data collection (A2: enhanced assurance): We provide information on the policy context within the statistical release, including a description of current government targets and funding programmes (see section on policy and operational within this document and the statistical release for further information).
• Communication with data supply partners (A2: enhanced assurance):  We have established an effective mode of communication with our data suppliers (see section on data collection for a description of how we communicate with data providers).
• Quality assurance principles, standards and checks applied by data suppliers (A1: basic assurance): we have broad knowledge of data suppliers QA checks (see section on validation and verification).
• Producer’s quality assurance investigations and documentation (A2: enhanced assurance):  we provide information on our quality assurance checks and provide guidance on the strengths and limitations of the data (see section on validation and verification and statistical release).

We consider the affordable housing statistics to be of medium data quality concern and of medium public interest as there is wide user and media interest. We are confident that the scores are appropriate according to the toolkit, both in terms of the data quality concerns and public interest level.

Welsh housing statistics adhere to the Welsh Government’s Statistical Quality Management Strategy, and this is in line with the European Statistical System’s six dimensions of quality, as listed in principle 4 of the Code of Practice for Statistics.

Details of the six dimensions, and how we adhere to them, are provided below.

Relevance

The degree to which the statistical product meets user needs for both coverage and content.

The data in this statistical release form the basis of evidence on affordable housing provision in Wales and are used by the Welsh Government, local authorities, and other housing organisations to monitor trends in the provision of additional affordable housing units over time. Other interests and uses of this data are outlined above.

We actively review all our outputs and welcome feedback.

Accuracy

The 'planned' figures are data providers’ best estimates and therefore may change when reported as 'delivered'.  As an indication of the accuracy of previous estimates , the number of additional affordable housing units ‘delivered’ in 2024 to 2025 was 3,643 -  0.5% lower than the 3,660 units that had been reported  as ‘planned’ for delivery during 2024 to 2025.

The ‘planned’ data shown in this release is based on information provided by local authorities and includes units planned by LAs, RSLs and ‘other’ providers.

Revisions

This release contains the final data for 2024 to 2025 financial year. However sometimes local authorities submit revised data in future years. If this happens, we will update the information in the following year’s statistical release.

We follow the Welsh Government’s statistical revisions policy.

Timeliness and punctuality

Timeliness refers to the lapse of time between publication and the period to which the data refer. Punctuality refers to the time lag between the actual and planned dates of publication.

All outputs adhere to the Code of Practice for Official Statistics by pre-announcing the date of publication through the Upcoming pages on the Statistics for Wales website. Furthermore, should the need arise to postpone an output this would follow the Welsh Government's revisions, errors and postponements arrangements.

We publish releases as soon as practical after the relevant time period.

Accessibility and clarity

Accessibility is the ease with which users are able to access the data, also reflecting the format(s) in which the data are available and the availability of supporting information. Clarity refers to the quality and sufficiency of the metadata, illustrations and accompanying advice.

Affordable housing statistics for Wales are published in an accessible, orderly, pre-announced manner on the Welsh Government website at 9:30am on the day of publication.

We aim to inform known key users of the publication of the statistics when they are published. An e-mail is circulated to the Housing Information Group.

All releases are available to download for free. More detailed data are also available at the same time on the StatsWales website and this can be manipulated online or downloaded into spreadsheets for use offline.

In our outputs, we aim to provide a balance of commentary, charts and maps where relevant. The aim is to ‘tell the story’ in the output, without the report becoming overly long.

We aim to use Plain English in our outputs and all outputs adhere to the Welsh Government accessibility policy. Furthermore, all our headlines are published in Welsh and English.

We regularly peer review our outputs internally.

Further information regarding the statistics can be obtained by contacting the relevant staff detailed on the release or via stats.housing@gov.wales.

A full set of data including information by individual local authority and individual RSL back to 2007 to 2008 is available to download from our StatsWales interactive website.

Comparability

The degree to which data can be compared over time and domain.

Prior to 2010 to 2011, no validation of ‘planned’ and ‘proposed’ figures was undertaken therefore there may be slight discrepancies between the estimates provided by both the LAs and the Welsh RSLs for years prior to 2010 to 2011 and so should be treated with caution. For the 2012 to 2013 data collection onwards RSLs were not required to report on the number of additional affordable housing units planned and proposed for delivery in future years. The ‘planned’ and ‘proposed’ data shown in this release is based on information provided by local authorities and covers all planned delivery by all providers in their local authority area.

Coherence

The degree to which data that are derived from different sources or methods, but which refer to the same phenomenon, are similar.

The Welsh Government also publish separate statistics on new house building. This data is based on the reports of local authority building inspectors and the National House Building Council (NHBC). Information is not collected from other small inspectors which is likely to lead to an under-count of the total number of new dwellings. It is sometimes difficult for building control officers who record the data to identify the intended final tenure of the property (the basis for the tenure information). This may lead to an under-count of social sector new house building and an over-count for the private sector. Therefore, the tenure data of new build statistics should be treated with caution.

Management information

Progress towards the Programme for Government 2021 to 2026 commitment is reported in this statistical release. Due to the nature of data collection, there is a time lag between the end of the reporting period and the publication of the official statistics. Official data for affordable homes delivered in 2025 to 2026, as well as the total delivered between April 2021 and the end of March 2026, will be published in autumn 2026.

To improve the timeliness of data, management information has been included in this statistical release to complement existing accredited official statistics. Estimates of homes delivered are available from management information collected throughout the year. This data supports monitoring of housing delivery linked to government funded programmes, including the Social Housing Grant (SHG), Transitional Accommodation Capital Programme (TACP), Registered Social Landlord (RSL) Loans scheme, and Leasing Scheme Wales, among others.

Management information is drawn from a live system that is continuously updated by RSLs and LAs. For each funding programme, providers update scheme milestones, completion dates, and add or remove schemes. As this system is continuously updated, projections change over time. For example, management information for the 2024 to 2025 financial year extracted in May 2025—one month after the end of the 2024 to 2025 financial year—estimated delivery of 3,489 homes. This figure increased to 3,650 when data was extracted in October 2025, six months after the financial year ended.

Recent efforts have focused on improving the quality and reliability of this data. Since May 2025, more programmes have been integrated into the main management system, with each scheme assigned a unique identifier to reduce the risk of double-counting. Work has also continued to improve data completeness across the system.

The management information referenced will be published alongside this statistical release as an Ad-hoc statistical requests on 13 November.

 The Chief Statistician’s blog has also been published on 13 November 2025 which explains more about affordable housing definitions and how the data can and can’t be used.

In recent years management information (excluding voids) has generally forecast higher housing delivery figures than those reported in the end of year official statistics. For the 2024 to 2025 financial year the management information indicated delivery of 3,650 homes compared to 3,530 reported from official statistics. A difference of 120 homes. 

To ensure the robustness of void data included in the measurement of the government target, a quality assurance exercise was conducted in September 2025 using the UK Statistics Authority’s Administrative Data Quality Assurance Toolkit. Two RSLs and two local authorities were selected by the TACP programme for interview. These interviews explored various aspects of data quality, including:

• How organisations defined voids eligible for TACP funding (e.g. vacancy length, condition, tenure)
• Timing and frequency of data recording and updates (e.g. whether it is updated through a live system or set time periods.
• Errors such as whether a unit might be recorded as a TACP void but not brought back into use, or whether double counting could occur between RSLs and LAs.
• Potential for previously delivered affordable homes to be reclassified as TACP voids
• Validation processes and sign-off procedures

Findings indicate that a robust quality assurance process is in place, with data captured at multiple stages—such as the expressions of interest form, grant applications, and scheme uploads to the portal. These are recorded at the individual scheme level and undergo validation to ensure accuracy and completeness. There remains a small possibility that a home previously reported as delivered since the start of affordable housing records in 2007 to 2008 could be included again. However, safeguards such as checks on funding history during grant applications help ensure properties are accurately classified. It is also very unlikely that the same property would be both recorded as delivered and subsequently counted as a void within this government term, thereby being double counted towards the target. 

Strengths

• The management information collected is to support monitoring of government funding housing delivery.
• The Information is updated throughout the year providing a timely estimate of housing delivery.
• The information is drawn from a wide range of government-funded housing schemes, providing a broad picture of delivery activity.
• Improvements in the process for collecting management information have reduced the risk of error and improved data completeness.
• In recent years, the quality and reliability of management information (excluding voids) have improved. As a result, the gap between management information and official statistics has narrowed, with both sources now offering a broadly consistent view of delivery.
• Voids data is captured at multiple stages, enabling record-level tracking with checks to minimise errors.

Limitations

• Management information does not undergo the same level of validation as official statistics. e
• As the management information is drawn from a live system, figures change when RSLs and LAs update scheme details. This can cause month-to-month fluctuations and limit in-year comparability.
• While progress has been made, work continues to ensure full and consistent coverage across all funded programmes within the management information system.
• Although highly unlikely, there is a small risk that a previously delivered affordable home could later become a void and receive funding again through the TACP scheme. Safeguards are in place to prevent this, and no such cases have been identified within schemes funded by current programmes.

On 6 November 2019, ONS published two reports on affordable housing statistics as part of a UK wide programme of work to improve housing and planning statistics:

1. Comparing affordable housing in the UK (ONS), an article making cross-UK comparisons of affordable housing statistics
2. Affordable Housing Statistics in the UK (Government Analysis Function), a review of definitions, terminology and the feasibility of harmonising affordable housing statistical definitions.

These reports provide detailed information on the definition of affordable housing in each country, the terminology used and a summary of the differences across countries.
