1. Purpose
WPPN 010 sets out full details of what Project Bank Accounts (PBAs) are and provides guidelines for contractors on how to set up a PBA.
The use of PBAs supports the Wellbeing of Future Generations (Wales) Act 2015 wellbeing goals of ‘A Prosperous Wales’, ‘A Resilient Wales’ and ‘A More Equal Wales’ in their positive impact on the economy and mental wellbeing by ensuring prompt and fair payment terms that relieve cash flow pressures, particularly on small to medium enterprises (SMEs).
This WPPN sets out a detailed explanation of PBAs, and guidelines for contractors on how to set one up. Welsh Contracting Authorities (WCAs) should also refer to WPPN 011 for advice on implementing Welsh Government PBA policy.
2. What is a Project Bank Account?
PBAs are ring-fenced bank accounts with trust status that act as a mechanism for making payments. PBAs replace the traditional multi-layered payment terms between tiers in the supply chain with simultaneous payments to the lead contractor and supply chain parties. Traditional payment methods have resulted in sub-contractors commonly having to manage 60-90 day payment terms. Payments via a PBA typically take between 3-5 days from the deposit of money into the account following certification of the payment schedule.
A PBA ensures that:
- Payments are accelerated through the supply chain
- Supply chain spend and payment flows are transparent
- Risks and costs linked to payment delays are mitigated through faster payment
- Risk of supply chain failure is reduced because of improved cash flow and payments protection mechanisms
- Interest accrued where PBAs are set up as interest bearing accounts can, subject to the agreement of the account Trustees, go to the main contractor
- PBAs do not involve WCA prefunding. Money is only deposited in the account when payment is due.
A PBA is made up of:
- Trustee(s) – depending on the type of account these will be the main contractor and / or the WCA who have responsibility for managing the PBA for the benefit of the ‘beneficiaries’.
- Beneficiaries – the main contractor and any participating sub-contractors who receive monies paid out of the PBA. Any supplier involved in the delivery of the project can be a Beneficiary, regardless of what tier they are in.
Participating sub-contractors can either join the PBA at the very start of the project or at a later date. To join, the sub-contractor signs a Joining Deed, which is then countersigned by the Trustee(s).
The payment process
The standard processes for assessing the quality and value of work completed and then authorising whether payment can be made, takes place as per the established payment cycle. Payments are still subject to correct invoices being submitted by sub-contractors and main contractors as per the agreed schedule of payments due. WCAs deposit the total amount of monies due into the PBA.
The amount paid into the PBA is then matched to the amounts due to each beneficiary (main and sub-contractors) and the bank is instructed to pay accordingly with beneficiaries receiving the amounts due into their bank accounts within 3-5 working days.
To facilitate this, contractors need to align their supply chain payment cycles and associated invoicing from sub-contractors with the PBA payment cycle agreed with WCAs.
3. Nominated Service Providers
