UK Government Guide On Late Commercial Payments

Recovery Costs

You can also charge a business a fixed sum for the cost of recovering a late commercial payment on top of claiming interest from it. The amount you’re allowed to charge depends on the amount of debt. You can only charge the business once for each payment.

Please check the following link to ensure the charges are up to date (latest check 06/05/2021):

Interest Rates

Currently (06/05/2021) interest rates are calculated based on 8% + Bank of England base rate. Please check the following link from HMRC.

 
Bank Of England Base Rate
The Bank Of England interest rate can be found here:

 
Statutory Interest Rate
This is the “interest rate” + “Bank Of England Base Rate”

Example Calculation

If your business were owed £1,000 and the Bank of England base rate were 0.5%:

– The annual statutory interest on this would be £85 (1,000 x 0.085 = £85)

– Divide £85 by 365 to get the daily interest: 23p a day (85 / 365 = 0.23)

– After 50 days this would be £11.50 (50 x 0.23 = 11.50)

– As the debt is over £1000 you can then add on £70 recovery cost.

Total owed (£11.50 + £70) = £81.50
