Every time the Bank of England meets, small business owners hold their breath for a rate cut that might ease the pressure. It’s understandable, but it’s misplaced. Interest rates are a fraction of a percentage point you can’t influence. Late payment is a much bigger problem sitting inside your own sales ledger — and unlike the base rate, you actually have some leverage over it.
The numbers back this up. The average UK small business is sitting on around £22,000 in overdue invoices at any given time, and late payment is pushing an estimated 38 UK firms out of business every single day. Compare that to the difference a quarter-point rate move makes to a typical small business loan or overdraft — it’s real, but it’s usually dwarfed by what’s sat unpaid on the books. If you’re a limited company waiting on a £15,000 invoice that’s 45 days overdue, no rate decision is going to matter as much as that cheque landing.
In March 2026 the government announced what it billed as the toughest late payment crackdown in a generation — a 60-day cap on payment terms from large firms, mandatory statutory interest, and new powers for the Small Business Commissioner. It’s welcome, but it still needs primary legislation and isn’t expected to land until late 2026 or 2027 at the earliest — so waiting for it isn’t a plan. The good news is you don’t have to wait. Under the Late Payment of Commercial Debts Act, you’re already entitled to charge statutory interest (8% above the base rate, so 11.75% right now) plus a fixed compensation fee on any overdue B2B invoice, whether or not your contract mentions it — most businesses never claim it. Beyond that: invoice the moment the work’s done rather than batching at month-end, set clear written terms so 30 days isn’t the default by accident, and chase a few days before the due date rather than after.
For sole traders the calculation is sharper, since there’s no separate business entity to absorb the wait — a late payment hits personal cash flow directly, today. Limited company directors have a little more buffer through the business account, but a habitually slow-paying client does the same damage eventually — it just shows up on the company’s books first.
None of this means rates don’t matter. But if you’re the kind of business owner who checks the MPC decision every six weeks and doesn’t have a clear view of who owes you what and how overdue it is, the priority is backwards. Is your energy going where it’d actually move the needle?
