Why UK tradespeople get paid late, and how to stop it

You finished the job on Friday. The customer was happy. They said the invoice would be paid "by the end of next week". Three weeks later, you are sending a polite follow-up email, wondering if you sound pushy, and trying to work out whether the customer will pay before your parts bill lands.

This is not a you problem. It is one of the most consistent problems in UK small business.

The reality

Nearly half of UK small businesses are getting paid later than they were a year ago, according to the FSB's 2025 report. Half expect it to get worse. And nearly a quarter are now waiting up to 60 days past the due date for money they have already done the work for.

It is worse for trades. A majority of small firms, 54%, were paid late in the last three months of 2025, and construction is among the hardest hit sectors. More than half of UK tradespeople are waiting on money this morning.

Most tradespeople are not losing money because customers refuse to pay. They are losing it because chasing feels harder than writing it off. The FSB has found that small businesses write off late payments up to ten times a year, just to avoid the hassle.

The good news is that almost every cause of late payment is fixable, and most of the fixes are simple. Below are five reasons it happens, the fix for each, and what to do when prevention fails.

The five reasons it happens

1. No clear payment terms. The quote did not say when the invoice was due. The invoice did not say when payment was due. The customer assumed "whenever". You assumed "soon". A week becomes three.

2. No sign-off, at either end of the job. Did the customer agree to this scope and this price in writing before you started? Did they confirm the work was complete before you invoiced? Skip either, and three weeks later the customer remembers the job differently. Suddenly the windows were supposed to be included, or the second coat looks patchy. Every chase becomes a renegotiation. This is the gap where late payment quietly turns into non-payment.

3. No invoice timing discipline. The job finishes on a Friday. You invoice on Sunday evening, or Monday morning, or "when you get a chance" later that week. By the time the invoice lands, the customer has moved on and so has the cash they had set aside.

4. No automated chasing. The invoice was due last week. You think "I should chase that". You do not chase. Another week passes. Now it feels awkward to chase, because if you had been on top of it you would have done it a week ago. Another week passes. The invoice has slipped into the category of "I will deal with it next week" forever.

5. No escalation framework. The customer has stopped replying. You know there are legal options. You do not know what they are, how much they cost, or whether they apply to a homeowner versus a business customer. So you do nothing.

Each is its own habit, and each is easy to fix.

The fix for each

Payment terms that customers actually see

The fix is to put the terms in three places: on the quote, on the invoice, and in whatever message confirms the customer has accepted the job. Not buried in terms & conditions. In plain text the customer cannot miss.

For homeowners, 14 days from invoice date is a fair industry norm. For repeat trade or commercial customers, 30 days. For larger jobs, a deposit plus staged payments.

A simple line at the bottom of every quote does the work:

Payment terms: 14 days from invoice date. Deposit of 25% required before materials are ordered.

That is it. The customer has now seen the terms before agreeing to the job. If they pay late, it is not a misunderstanding.

For the four clauses that materially affect getting paid, including the legal basis for late payment interest and a stop-work clause for staged jobs, see our guide to writing payment terms that actually get you paid.

The manual version: save the terms line as a text replacement shortcut on your phone, so it appears whenever you type "terms". If you quote on paper, get a stamp made.

Sign-off at both ends of the job

This is the gap that costs the most, and the one most tradespeople skip. There are two moments you need to nail.

Before you start. When the customer agrees to the work, you need that agreement in writing, with the scope, the price, and the date. The strongest version is a digital quote the customer accepts with a signature and timestamp. The next best is an email reply that says "I accept the quote dated [date] for £[amount]." The weakest acceptable version is a WhatsApp from the customer confirming the price and scope in their own words. This is what protects you against "I never agreed to £1,500" three weeks later.

Before you invoice. Before you raise the invoice, get the customer to say in writing that the work is done and the price is right. Not "looks good, thanks" in passing. A clear yes. The easiest version is a text at the end of the job: "Just to confirm, the work agreed is complete and the total is £X." That single message saves more disputes than any other piece of admin. For bigger jobs, a printed sheet works: a one-page summary of what was agreed, what was delivered, the total, and a signature line. Take a photo of the signed sheet before you leave.

With both in writing, every chase is a chase for an agreed debt. Without them, every chase is a chance for the customer to renegotiate what was agreed at the start, or whether you actually finished it.

The manual version: save both messages (the email asking for written acceptance, and the end-of-job confirmation) as phone shortcuts. For bigger jobs, keep a stack of one-page sign-off sheets on a clipboard in the van.

Invoicing on the day the work is finished

The single biggest change you can make. An invoice sent the moment the job finishes lands while the work is fresh and the customer still feels the relief of having a working boiler, a finished kitchen, or a roof that no longer leaks. An invoice sent on Tuesday lands while they are thinking about something else.

If you cannot invoice on the day, send a quick "job complete, invoice to follow within 24 hours" message so the customer knows it is coming. The exact timing does not matter. What matters is that you are a business that takes its own admin seriously.

The manual version: use an invoice app on your phone, or keep a saved template in your email drafts folder that you copy and edit.

Chasing without it feeling like chasing

Chasing feels awkward because it usually happens too late. By day 21 it feels like an accusation. By day 7 it is just a polite reminder.

Here is the cadence that works:

• Day -2 (before due date): "Friendly reminder, invoice X is due on the 15th."
• Day +1 (one day late): "Quick nudge, the invoice was due yesterday. Let me know if there is any issue."
• Day +7: "Following up on invoice X, still unpaid. Could you confirm the payment date?"
• Day +14: "This is now two weeks overdue. If I do not hear from you by [date], I will start charging late payment interest and look at next steps."

The first two messages should feel like admin, not confrontation. The third is firm but reasonable. The fourth introduces consequences.

The other reason chasing feels awkward is that it feels personal. If it is automated, it is not. Everyone gets the same reminder when their payment is past the due date.

The manual version: when you send an invoice, add four diary entries (the day before, one day after, seven days after, fourteen days after). Save the four messages as email drafts. When the diary alert fires, open the draft, change the name, send.

A clear escalation framework

If day +14 passes without payment, you need to know what comes next. Most tradespeople do not, which is why they stop. For the full step-by-step playbook, see what to do when an invoice goes unpaid. The short version:

1. Send a formal "Letter Before Action" giving the customer 30 days to respond. Where the customer is an individual or a sole trader, the Pre-Action Protocol for Debt Claims requires this time and specific information in the letter. Where the customer is a limited company, the protocol does not strictly apply, but courts still expect reasonable pre-action conduct. Our guide to sending a letter before action explains how, and our free generator writes the letter for you.
2. If no response, file a money claim via gov.uk. You pay a court fee when you file, which scales with the size of the claim. If you win, the customer is normally ordered to pay it back.
3. If a County Court Judgment is granted, the customer has a month to pay before it hits their credit file for six years. Every mortgage, every car loan, every credit check after that point will show it. Most customers do not want this on their record, which is often why the threat of a CCJ gets the invoice paid.

For higher-value or disputed debts, the Small Business Commissioner has free guidance.

The manual version: keep a printed copy of a Letter Before Action template in the van or in a folder at home. The moment day +14 passes, fill it in by hand and post it recorded delivery the same week. Not next week. The same week.

Charging interest on late invoices

There is one thing every UK tradesperson should know: whether you can charge interest on a late invoice depends on who the customer is.

If the customer is another business, you can charge interest. Under the Late Payment of Commercial Debts (Interest) Act 1998, you can charge 8% on top of the Bank of England base rate on any business-to-business invoice that is paid late. You can also charge a fixed fee for the hassle of chasing: £40 for debts under £1,000, £70 up to £9,999, and £100 for £10,000 or more.

If the customer is a homeowner, the rules are different. That law does not apply. To charge interest on a homeowner's late invoice, you need it written into your payment terms (which is why having terms on every quote matters). If you end up in court, the court can still award you interest under Section 69 of the County Courts Act 1984, usually at 8% per year. Citizens Advice has the exact wording to use on the claim form.

Scotland works differently, with a smaller small-claims threshold of £5,000.

Why trades struggle with this specifically

The five habits above will work for any small business. But for trades, there is one extra thing in the way: most of your customers are not just customers. They are the woman whose mother used you for her bathroom and who recommended you to her daughter. They are your wife's cousin's neighbour. They are the man two doors down. The relationship is not transactional, and that is precisely the problem.

When the customer is also a neighbour, a referral, or a friend of a friend, every chase email feels like a referendum on the friendship. Nobody wants to be the painter who took Sue to court, or the spark who fell out with the family next door. So the invoice slips. And eventually it gets written off, because the social cost of chasing feels higher than the cash cost of not.

By the time anyone is agonising over whether to take a customer to court, the system has already failed. The reason it got this far is not a missing legal strategy. It is that there was no payment-terms conversation up front, no written quote acceptance, no completion sign-off, no invoice on the day. The escalation question is the wrong question. The prevention question is the right one.

The fix is not to become harder. It is to make the admin so routine that it stops being personal. When every customer gets the same payment terms, the same invoice on the day, and the same automated reminder on day +1, there is nothing to take personally. The neighbour is not being chased. The system is doing what it does for everyone.

Doing this in real life

None of the above requires software. It requires a decision, made once, that this is how you run your business now. The manual hints inside each section above are the genuinely manual versions; phone shortcuts, email drafts, diary entries, a clipboard in the van. They work.

Trame can do all of the above automatically: quotes the customer accepts digitally with a signature and timestamp, completion sign-off on your phone, invoices, reminders. The habits are the answer. The tool is just a way of not having to think about them.

The reason most tradespeople get paid late is not a lack of legal knowledge, or a difficult customer, or a missing piece of software. It is five small admin decisions that, repeated over a working year, compound into thousands of pounds left on the table and dozens of hours of low-grade stress that should not have existed in the first place.

You did the work. You deserve to be paid on time, by people you can still wave at over the garden fence. That is not a customer service problem, or a legal problem, or a software problem. It is just a habits problem. And habits, once they are routine, stop feeling like work.
