The proposed site will be used to inspect goods entering Wales from the EU via the Port of Holyhead. This includes sanitary and phytosanitary (SPS) goods such as:

  • animals
  • plants
  • products of animal origin.

Depending on the product, most inspections will be carried out by:

  • local authorities
  • Port Health Authorities
  • Animal and Plant Health Agency.

The site would include parking areas for HGVs and other vehicles. Security measures and facilities will enable the checking of goods.The site lies to the south-east of the HRMC Inland Border Facility (IBF) off the existing service road used by a number of HGVs. The site provides convenient transport links with nearby access to and from the Port of Holyhead and the A55 linking with mainland Wales.

The site currently includes an emergency HGV stacking facility. This was built during the EU Exit transition period.

The border control post would consist of separate inspection facilities for plant produce, small animals and horses. Office buildings would be up to two stories tall and inspection buildings would be large enough to facilitate all HGV sizes.

Site staff would include fully trained security personnel and emergency response staff. Closed Circuit Television (CCTV) and Automatic Number Plate Recognition (ANPR) cameras would be positioned across the site to monitor site activities. Secure perimeter fencing would also be installed.

After entering the site, HGVs would visit the Vehicle Entry Check Point before being directed to a vacant HGV space. From there, the HGVs would undertake inspection checks as required. During processing, HGV drivers must remain at the site unless instructed otherwise. Once the checks have been completed, the HGVs would leave the site to continue on their journey.

Scheme design

Traffic flow and access

Directing vehicles to the border control post

The site is located close to the Strategic Road Network and the Port of Holyhead and the site would be directly accessible from the A55. Signage would be in place to direct drivers to site from the Port. In the event of any closures of the A55, the A5 would be used to access the site.

Prominent road signage

There would be prominent bilingual road signage that directs HGV drivers to the border control post. There would also be signs outside the site entrance to advise hauliers about the use of site facilities and providing site contact details.

Entry and exit points at the facility

There would be one point of access and egress to the site. HGVs would be separated by the site design, whereby HGVs arriving would be directed into dedicated holding lanes and HGVs egressing would be directed out via the existing site egress.

Staff would access and egress the site via the existing site access/egress point but would be directed to a dedicated staff car park.

Measures would be implemented to discourage drivers from exiting the site and using the highway towards Trearddur Bay Country Park.

Environment and landscaping

As part of developing site-specific proposals for the border control post, environmental assessments continue to be carried out and relevant bodies, including Cadw, Natural Resources Wales and relevant officers within the Local Planning Authority, continue to be engaged about the environmental assessment and design of the site.

A landscape strategy would be developed at the site which would provide measures to minimise the potential for adverse environmental effects.

As part of the SDO process, an environmental report has been produced. This assessment takes into consideration air quality, cultural heritage, landscape and visual effects, biodiversity, road drainage and water, and noise. The report also considers geology and soils, material assets and waste, population and health, climate, and cumulative effects. A Habitats Regulations Assessment (HRA) has also been produced. Please see Planning Documents section on this webpage to access these reports.


How we consulted

In August 2021 we applied under section 59(3) of the Town and Country Planning Act 1990 to use Plot 9, Parc Cybi site. This application was made under the requirements of a Special Development Order (SDO).

The SDO application seeks a permanent consent for a border control post. This sets out required limits on the facility's construction and operational stages. This includes aspects such as the building height and noise.

29 August 2023

The UK Government has now released the final Border Target Operating Model, which lays out the new processes for security controls (applying to all imports), and sanitary and phytosanitary controls (applying to imports of live animals, animal products, plants and plants products). The changes laid out by the Border Target Operating Model will be phased in gradually, beginning with the pre-notification and certification process in January 2024. This website will be updated with the remaining schedule in due course.

20 April 2023

Planning permission has been granted via a Statutory Development Order (SDO) under section 59(3) of the Town and Country Planning Act 1990. Periods of public and technical stakeholder consultation have now closed.

16 November 2022

In April this year, the UK Government announced the further introduction of border controls would be suspended until the end of 2023. A revised border approach is currently in development. 

Following this revision of border controls the Border Control Post facility in Holyhead is now planned to be smaller than initially envisaged, this allows for some land to continue to be used for HGV parking and the SDO is being amended to reflect this. 

Welsh Government invited residents and technical stakeholders to comment on these proposals. You can view the letter and the revised site plan: Amendments to Parc Cybi Border Control Post, Holyhead Special Development Order. Construction on the site is expected to commence in early 2023 with an operational date of early 2024.

April 2022

Kier were appointed in April 2022 as the contractor for the proposed BCP.

10 March 2022

The Welsh Government Minister for Economy has appointed the contractor for the design stage of the proposed Border Control Post at Parc Cybi.

During this stage the contractor will work with Welsh Government to produce detailed designs for the facility, confirm a cost and timetable. For more information see: Written Statement: Update on Border Control Posts

Construction work on the proposed site at Plot 9, Parc Cybi, Holyhead will not start until the build stage of the contract is agreed, expected in the summer 2022. The build stage is also subject to the granting of planning permission via a Special Development Order (SDO) – a decision is expected in May 2022.

7 December 2021

The views of individuals and organisations on the proposals during a public consultation during March to April 2021 have been recorded in a consultation engagement report: Parc Cybi Border Control Post: Special Development Order. All comments have been taken account of and used to inform the planning process.

Officials have drafted a more general update on the progress of the Parc Cybi Border Control Post below, and provided a concept plan for how the build will look. This plan is subject to change. Any changes will be within the Consenting Envelope, which limits the size and scope of the Border Control Post as explained in the progress update and the FAQs below.

Current position on BCP design and delivery in Wales.

Holyhead Port: site  

The Holyhead BCP will be located on Welsh Government owned land at Parc Cybi, Holyhead, some 1.7 miles from the port. The site has already been partially developed as a HGV stacking area as part of the contingency planning for the end of the EU transition period. At 15 acres it provides space for swim lanes, fencing, inspection buildings, offices, parking, sustainable drainage, screening and other environmental mitigations. 

Holyhead Port: planning

Planning permission is being sought via Special Development Order (SDO) under section 59 of the Town and Country Planning Act 1990. Planning permission and any conditions are made through a Statutory Instrument (SI). The planning application was submitted to Welsh Ministers on 6 August 2021. The Welsh Government Minister for Climate Change will take the decision whether to grant the SDO or not and this is expected by April 2022.

The application proposes a ‘Consenting Envelope’. This sets out a maximum limit for the assessed parameters of the development, within which all development will be limited. The Consenting Envelope will ensure that the final design of the BCP does not trigger significant environmental effects, whilst also allowing an appropriate degree of flexibility to accommodate design developments. In addition, the SDO limitations will be designed to mitigate the potential impacts of the development.

There is no statutory requirement to consult before making a SDO. However, community consultation was undertaken for a period of 21 days from 24 March 2021 until 13 April 2021 and technical stakeholders received an extended period. The consultation departed from the Welsh Government policy of allowing a 12-week period. This departure was to allow for early engagement with stakeholders before major planning of the BCP began so that their views could be taken into account whilst meeting the timelines for the introduction of checks, as set out in the UK Government’s Border Operating Model (BOM).

Holyhead Port: designs

The BCP is a bespoke facility designed to accommodate checks on the full range of SPS controls on live animals, animal products, plants, plant products and wood from the EU and the possible acceptance of rest of world (ROW) SPS trade.

At 15 acres, the site will provide space for:

  • swim lanes,
  • fencing,
  • inspection buildings,
  • temperature controlled storage
  • offices
  • parking
  • sustainable drainage
  • screening and
  • other environmental mitigations.

Concept designs are near complete and Welsh Government is undertaking a BREEAM assessment of the development’s environmental, social and economic sustainability performance with a target rate of BREEAM Excellent.

Detailed designs will be developed in conjunctions with the appointed construction Contractor. The published concept design is correct as of 11 August 2021. It should be noted that this is not final and is subject to revision as requirements and detailed designs are refined.

Holyhead Port: construction

Welsh Government issued the construction invitation to tender (ITT) on 9 August 2021 and it closed on 23 September 2021. The ITT was issued via the North Wales construction Partnership framework, administered by Denbighshire County Council.

A 2 stage design and build procurement strategy has been selected. The 2 stage approach is structured as follows:

  • stage 1: contractor’s design team works alongside Client design team to improve deliverability, programme works, establish supply chain and refine project cost.
  • stage 2: on agreement of project cost established at end of Stage 1, the contract for the construction works will be confirmed and the Contractor will commence site works.

The stage 1 contract is expected to be awarded in 2022. The award does not prejudice the outcome of the SDO decision.

Construction completion is expected in late 2022 / early 2023 with an operational date of early 2023.

9 June 2021

The Department is currently working through all feedback received from the community and undertaking relevant surveys at the site. We are continuing to work with key stakeholders to develop our design, ahead of submitting any planning application to Welsh Ministers for review.
