The PPC has 3 core points which the signatories are expected to adhere to. They are quite simple.
Large business that submit data to the Government regarding their payment practices and report less than 90% of invoices are paid within 60 days are suspended from the Code until improvements are made and the PPC administrators can remove any company from the Code which it deems to have unsatisfactory payment practises and will be publicly announced via Small Business Commissioner's office.
As a summary, the PPC serves to improve payment practices between organisations and you can generally trust the signatories to settle their invoices in a timely manner.
The Government announced in November 2018 that from 1 September 2019, any organisation that bids for a central government contract more than £5 million a year will need to demonstrate it has effective payment systems in place to ensure a reliable supply chain.
In October 2021 the UK Government went further and published the Procurement Policy Note 08/21. For most major government contracts in excess of 5million GBP, there will be a tightening of the rules during the pre-qualification process relating to the timely payment of supply chains.
This new procurement rule came into effect from April 1st, 2022, and includes:
Whilst the procurement policy is separate from the Prompt Payment Code, it is effectively nudging businesses which are bidding for UK government contracts to conform to the code’s rules.
So, Company's which have not signed up to the Prompt Payment Code, will still have to comply if they wish to bid for public sector projects. However if a company cannot show that they settle invoices within the timeframe, any bids you make for government work are likely to be rejected.
The government also clarifies that new businesses that do not have a long record of paying suppliers (and so cannot prove compliance) will still be able to apply for government work.
