Over the last few years, the UK government has introduced several reforms to the Prompt Payment Code - an initiative designed to speed up cash flow in UK industry. And this means that the question of how fast you pay suppliers is becoming ever more pertinent.  

The government introduced a significant update to the Prompt Payment Code last July. And as of April 1st, 2022 – due to the government’s Procurement Policy Note 08/21 – compliance with the standard effectively becomes mandatory for businesses that bid on major government contracts.  

Understanding the Prompt Payment Code is vital if you run a construction business that works on public sector contracts.  

Here is what you need to know about the Prompt Payment Code in 2022: 

What is the Prompt Payment Code? 

The Prompt Payment Code is a voluntary code of practice for businesses, designed to encourage supplier payment in 30 to 60 days, depending on the supplier size. It was first introduced in 2008 as a response to calls from companies for changes in payment culture.  

Because the code is entirely voluntary, businesses do not have to comply. That said, over 3,300 big UK buyers have signed up – including major construction firms, retailers, banks, public sector authorities and a range of small and medium-sized businesses.  

As of July 1st, 2021, complying with the reformed Prompt Payment Code requires:

  • A senior person at the buying company (CEO, CFO etc.) to personally take responsibility for payment practices
  • Signatories to produce an annual report and explain any delays
  • Signatories to allow suppliers to charge late payment interest on delayed invoices
  • If the buyer cannot pay the supplier within the agreed timeframe, they must contact suppliers to explain why 

Changes to expect from April 1st, 2022 

 In October 2021, the government published the Procurement Policy Note 08/21. For most major government contracts – £5million plus – 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 will come into effect from April 1st, 2022, and includes: 

  • An automatic pass threshold of 95% of invoices paid within 60 days.  
  • This is measured over two 6-month calendar reporting periods. 
  • The next level threshold, where you are not hitting the 95% target, will be between 90% and 95%. But you must provide information on why you didn’t meet the threshold with an action plan to correct it.
  • The automatic failure threshold will be anything below 90% in the 60-day period. 

To be clear, this procurement policy is separate from the Prompt Payment Code, but it is effectively nudging businesses that want to bid for government work to conform to the code’s rules. 

So, even if your company has not yet signed up to the Prompt Payment Code, you will have to comply anyway if you want to work on public sector projects. If you cannot show that you pay 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.  

Challenges when complying with the Prompt Payment Code 

Although the Prompt Payment Code is straightforward in theory, complying with the standard can be challenging in practice.  

For example, when the prompt payment ‘clock’ starts can be unclear – the clock being the first day of the 60-day payment window. 

Usually, suppliers will view the payment clock as starting when they send the invoice. Yet there are several reasons that the buyer may not see and process it within 60 days. The invoice could: 

  • get lost in the post 
  • not be noticed in accounts payable’s inbox 
  • sent to the incorrect email address, or land in the spam folder 
  • Have the wrong information on the invoice 
  • require manual rekeying that leads to costly mistakes 

These factors could mean that a buyer pays an invoice later than expected and is deemed a late payer  

Invoices often need to be returned to the supplier to make necessary changes. As a result, the clock continues to tick for payment and does not restart, despite the lost time.
