How to Deal with Late Payments as a Tradesperson UK (2026) — What Actually Works

Late payment is one of the most corrosive problems in the trade sector. A 2025 survey by the Federation of Small Businesses found that UK small businesses are owed an average of £25,000 in late payments at any given time. For sole trader tradespeople, a handful of unpaid invoices can turn a profitable month into a cash flow crisis.

This article covers what actually works — not the standard advice to "set clear payment terms," but specific tactics, tools and legal options that change the behaviour of late-paying customers.

Prevention first: reducing late payment before it happens

The most effective late payment strategy is structural — making it easy to pay, uncomfortable not to pay, and clear from the outset what the terms are.

Take a deposit on booking

Require a 20-30% deposit before you schedule larger jobs. This does two things: it filters out unreliable customers who vanish when asked for money upfront, and it creates a psychological commitment that makes completion payment much more likely.

For jobs under £300-500, deposits aren't usually worth the friction. For anything larger, they're worth the occasional pushback from customers who aren't going to pay properly anyway.

Send a payment link the same day

Invoices sent on the day of completion are paid 40-60% faster than invoices sent days later. The customer is still in the warm afterglow of a completed job, the work is fresh in their mind, and paying feels natural. Invoices sent three days later feel like an administrative chore.

Send your invoice before you leave the site. If you use Trade2Base, you can create and send an invoice from your phone in under two minutes — including a Stripe payment link so the customer can pay immediately by card or Apple Pay.

Make payment as easy as possible

Bank transfers require the customer to log into their banking app, add your account details, and manually create a payment. Many customers put this off until the weekend, or forget entirely.

A payment link in your invoice removes all that friction. The customer taps the link in your WhatsApp message, Apple Pay pops up, they double-click the side button, done. Payment takes literally three seconds.

State your payment terms clearly on every quote

Your quote should state: payment terms (e.g., "Payment due on completion" or "7 days net from invoice date"), your preferred payment method, and any late payment interest you charge.

Under the Late Payment of Commercial Debts (Interest) Act 1998, you are entitled to charge 8% above the Bank of England base rate on overdue commercial invoices. For domestic customers, you can't use this Act directly, but stating a late payment policy in your terms still creates a clear expectation.

When payment is late: escalation sequence

Most late payments aren't malicious — they're disorganised. The customer meant to pay but forgot, or the invoice got lost in their inbox. A structured escalation sequence resolves most late payments without confrontation.

Day 1 overdue: friendly reminder

Send a short, warm message — not accusatory, just a nudge. Something like:

“Hi [Name], just a quick reminder that invoice #123 for £[amount] was due yesterday. You can pay via the link in the invoice: [link]. Let me know if you have any questions.”

This resolves around 60-70% of late payments. Most people feel a bit sheepish and pay straight away.

Day 7 overdue: firm reminder

More direct, still professional:

“Hi [Name], following up on invoice #123 for £[amount] which is now 7 days overdue. Please pay at your earliest convenience using the link below. If there's an issue with the invoice, please let me know so we can resolve it.”

Day 14 overdue: final notice

State that you will be taking further action if payment isn't received:

“[Name], invoice #123 for £[amount] is now 14 days overdue. This is a final notice before I take further action to recover the debt. Please make payment immediately using the link below, or contact me today to discuss.”

Trade2Base automates this entire sequence — you set the reminders once and they go out automatically at the right intervals. You only get involved when someone replies or when you need to escalate.

Legal options for recovering payment

County Court Claim (Small Claims)

For amounts under £10,000, you can file a claim in the County Court online at gov.uk/make-court-claim-for-money. The filing fee ranges from £35 to £455 depending on the amount claimed. If the customer doesn't respond or defend the claim, you'll typically get a default judgment in 14 days — which you can then enforce.

This sounds complicated but it isn't — the online form is straightforward and most claims for unpaid trade invoices are uncontested. The threat of a County Court Judgment (CCJ) on a customer's credit record is often enough to prompt payment before the case goes any further.

Before filing, send a formal Letter Before Action. You can find templates at gov.uk. This is required before a court claim and often results in payment without needing to actually file.

Statutory Demand

For debts over £750 owed by a business (not a consumer), you can serve a Statutory Demand. If the business doesn't pay within 21 days, you can apply to wind them up. This is a nuclear option but carries real weight — most businesses facing a Statutory Demand will pay rather than risk winding-up proceedings.

Get legal advice before using a Statutory Demand. It's not appropriate for consumer customers or disputed debts.

Debt collection agencies

Debt collectors work on commission — typically 15-25% of the recovered amount. They're useful when legal proceedings feel disproportionate or when you have multiple small overdue invoices. Look for a member of the Credit Services Association (CSA).

Before using a debt collector, check whether the fee eats the recovery to the point where it's not worth it. On a £400 invoice, a 20% commission means you recover £320 less fees.

Late payment interest: your legal right

The Late Payment of Commercial Debts Act 1998 applies to B2B invoices. You're entitled to:

• Statutory interest at 8% over the Bank of England base rate on the overdue amount
• A fixed debt recovery fee: £40 on invoices up to £1,000; £70 on £1,001-£10,000; £100 on over £10,000
• Reasonable recovery costs beyond the fixed fee

You don't need to claim this — but mentioning it in your Letter Before Action adds weight and is entirely within your rights. For domestic consumers, you can still include a late payment clause in your contract, but the statutory rights under the 1998 Act don't apply.

Protecting yourself going forward

1. Check customers before taking large jobs — for commercial customers, run a quick credit check. Creditsafe and Companies House both have free information. A business with County Court Judgments against it is a red flag.
2. Keep signed quotes — a signed quote is a contract. If a dispute arises, a signed document showing what was agreed, at what price, with your payment terms, is invaluable.
3. Document everything — photos on completion, sign-off from the customer, any verbal changes to scope confirmed by WhatsApp message. Paper trails win disputes.
4. Don't do more work for customers who haven't paid — if a customer has an overdue invoice, do not start new work until it's settled. Some businesses use slow payment as a way to extract more work before paying nothing.

When to write it off

Sometimes the cost of pursuing a small debt (time, stress, legal fees) exceeds the amount owed. For invoices under £150-200 where the customer is clearly not going to pay and legal action feels disproportionate, the most sensible decision is often to write it off, learn from it, and move on.

Write the invoice off as a bad debt in your accounts (your accountant can advise) — this reduces your taxable profit by the amount of the debt. And add the customer to your "do not take work from" list.
