The Small Business Commissioner will be given sweeping new powers to investigate poor payment practices, adjudicate payment disputes, and fine the worst offenders – with fines worth tens of millions for firms that persistently pay late or fail to comply with the new laws. 

The measures will tackle a problem costing the UK economy £11 billion every year and ease the cost of living for entrepreneurs and SME owners who are often forced to wait months – or even years – to receive money they have already earned and having to chase endlessly to receive it. 

Some 38 businesses shut their doors every single day because they are not paid on time – the equivalent of 266 a week, and well over a thousand in any given month.  

Every small business owner, including tradespeople, freelancers, family firms and the self-employed, have to waste time and money chasing unpaid invoices when they could be growing their business. 

These measures, which will be the toughest in the G7, build upon and strengthen legislation on late payments, first laid out in the 1998 Late Payment of Commercial Debt Act, over 25 years ago. 

The changes will include a new 60-day cap on payment terms on all large firms when paying smaller suppliers. 

New mandatory interest on late payments will also be introduced, with a requirement for all commercial contracts to include statutory interest set at 8 per cent above the Bank of England base rate.   

For example, if a small business is owed £10,000 by one of its customers and is paid 60 days later than the agreed payment date, they will be owed £10,293.15 including mandatory interest (£10,000 plus £193.15 interest plus £100 compensation).

Business secretary Peter Kyle (pictured) said: “Far too many businesses are forced to shut down because they have not been paid – that is simply unacceptable. 

 “We are unveiling the strongest, most robust changes to payment laws in over a generation – laws that will transform the fortunes of small businesses for years to come and make their day to day lives much easier.” 

 After working closely with the Federation of Small Businesses, boards or audit committees of persistently late-paying large companies will be required to publish explanations for poor payment performance and the actions they are taking to address it. 

FSB policy chair Tina McKenzie said: “Late payments are a blight on our economy, so FSB is pleased to have worked in partnership with the Government to deliver the toughest legislation in the G7. 

“The new laws will finally bring a stop to big businesses using their small suppliers as sources of free credit.

“For the first time, audit committees and boards will question and challenge poor payment performance, publish it in annual reports for all to see, and put it right. 

“Paying in 60 days is not prompt - but strengthening that as the absolute maximum cap after years of dithering is a good step towards encouraging payments in 30 days across all supply chains. 

“Improving the Small Business Commissioner’s powers will also help, mandating CEO's of Britain's poor payers to take the phone call.

 “This is real progress, and we’ll keep working with the Government to make sure new laws are brought in as soon as possible.”
