Chasing an Unpaid Cleaning Invoice: The Playbook That Doesn't Need a Solicitor

Here's an opinion you'll either nod at or bristle at: the outcome of an unpaid invoice fight is decided long before anyone stops replying to emails. It's decided on the day you sent the quote.

A cleaning business owner wrote to us recently about £640 owed on a commercial office contract. Four months of emails, a solicitor quoted £180 to send a letter, and the client had already started using a different firm. The business won in the end. It won because it had a signed quote, a photo log of every visit, and a WhatsApp thread confirming the scope change that pushed the invoice up. Without those three things, the same claim would have been a coin toss.

The point isn't that the system worked. It's that it worked because the groundwork existed. Most small cleaning businesses already have the raw material for this — they just don't realise it counts until it's needed.

The usual caveat: this is general information, not legal advice, and the figures below should always be checked against GOV.UK before you file anything.

The evidence that decides cases

Judges deal in what can be shown, not what happened. Build the file from day one and a small claim becomes a paperwork exercise rather than an argument.

• A written quote or contract the client accepted in writing. An email saying 'yes, that's fine, start Tuesday' is worth more than a verbal agreement with a handshake.
• Timestamps on before-and-after photos. Your phone does this automatically. A dated photo of a kitchen on the day of a deep clean answers most quality disputes before they start.
• Check-in messages. A short text on arrival and departure isn't admin theatre — it's proof of attendance.
• Timesheets or sign-off sheets for commercial work. Even a cleaner's initials and a time on a communal log beats nothing at all.
• Records of variations. Any extra work agreed verbally should be confirmed by text the same day: 'Just to confirm, we did the oven interior as discussed, £35 added to this month's invoice.'
• The invoice itself, with terms. Payment terms of seven or 14 days, bank details, and a note that interest may be charged on late payment.

For commercial clients, the Late Payment of Commercial Debts (Interest) Act 1998 gives you statutory interest at 8% above the Bank of England base rate, plus fixed compensation of £40 for debts under £1,000, £70 up to £10,000, and £100 beyond. It's not going to make you rich, but mentioning it in a letter has a remarkable effect on a finance department's sense of urgency. Domestic clients don't fall under it.

Step one: the reminder that isn't a threat

Nine times out of ten this is where it ends. A short, warm, specific email — invoice number, amount, date, due date, how to pay — sent on day three past due. No apology for asking. No 'sorry to bother you'.

Follow with one more after seven days. Keep every message. If the client offers a payment plan, take it and confirm the schedule in writing. A client who pays £160 a month is worth more than a CCJ you'll never collect on.

Step two: the letter before action

If two reminders get nothing, send a formal letter before action. This is the bit people skip, and it's the bit that matters most.

It should state the amount owed, what it's for, that you intend to issue court proceedings if it isn't paid, a clear deadline (14 days is standard), and how to pay. Send it by email and post, and keep proof of both.

One important wrinkle: where your debtor is an individual — including a sole trader — the Pre-Action Protocol for Debt Claims applies. That means a Letter of Claim in a prescribed format, with a reply form the debtor can use to admit the debt, dispute it, or ask for time, and a full 30 days before you file. Skipping this can cost you costs later even when you're completely in the right.

Step three: Money Claim Online

For most cleaning invoices this is Money Claim Online, the government's portal for county court claims in England and Wales. It's built for exactly this: a form, a fee, and a claim that gets issued without you setting foot in a court building.

Court fees scale with the amount claimed — a debt of a few hundred pounds typically costs somewhere between £35 and £70 to file online, and you add the fee to your claim. Interest at 8% can generally be claimed too. If your claim stays on the small claims track, costs are limited but the process is informal and designed for people representing themselves.

Be realistic about the value of your time. Chasing £180 through the courts is a statement about your boundaries, not a profit centre. Chasing £1,800 is straightforwardly sensible.

Step four: making the judgment stick

Winning is the easy half. There's no point holding a judgment you can't enforce.

Request a warrant of control. County court bailiffs attend the debtor's premises. The fee is added to the debt, and the threat alone often produces a payment within days.

Consider an attachment of earnings if the debtor is employed and you know where. It's slow but steady.

Use a third-party debt order to freeze money sitting in their bank account — useful when you have reason to believe funds are there.

Look at transferring up to the High Court for enforcement by a High Court Enforcement Officer on larger debts; it's a heavier tool with a correspondingly heavier effect.

Scotland plays by a different rulebook

If the client is north of the border, ignore everything above about county courts. Scotland uses Simple Procedure for claims up to £5,000, lodged through Civil Online with the Sheriff Court. Application fees run from around £20 for the smallest claims to roughly £145 at the top of the range, and the debtor has a set period to respond before a hearing is fixed.

Enforcement is by Sheriff Officers rather than bailiffs, and the interest rules under the commercial debts legislation still apply UK-wide. One more thing worth knowing: the limitation period in Scotland is five years, not six.

The argument worth making

There's a school of thought in this industry that chasing small invoices is a waste of energy and you should just write them off and move on. It's wrong, and not for the reason you'd expect.

You don't chase the £200 because £200 changes your year. You chase it because the moment you become known as someone who doesn't pursue debts, your late-payment problem gets three times worse. Word travels in commercial cleaning. So does the opposite reputation.

Send the reminder. Send it on day three. Keep the photos.
