Statutory demand for an unpaid invoice: when it works and when it backfires

A statutory demand is the most misunderstood document in UK debt recovery. It looks like a strongly worded chaser and costs nothing to send, so it gets used as one. It is not. It is the formal first step towards winding up a company or bankrupting an individual, and its power comes entirely from the fact that you might follow through. Against a company the debt must be at least £750; against an individual, more than £5,000. The debtor gets 21 days to pay, secure or compound. If they do not, you may petition, which currently costs about £2,900 up front. And if the debt turns out to be genuinely disputed, the demand can rebound into a costs order against you.

A statutory demand is not a letter before action

The two get confused because both are written demands with a deadline. They do completely different jobs.

A letter before action is a pre-court step. It sets out the debt, quantifies interest and compensation, and warns that you will issue a claim. Where the debtor is an individual or sole trader, the Pre-Action Protocol for Debt Claims governs what it must contain and gives 30 days to reply. It leads towards a judgment.

A statutory demand leads somewhere else entirely. It does not ask a court for anything, and no court sees it when you serve it. Its whole function is evidential: an unsatisfied demand means the debtor is deemed unable to pay their debts, which is the ground you need to present an insolvency petition. You are not saying “pay me or I will sue you”. You are saying “pay me or I will try to close you down”.

That is also why it needs no court fee to issue, which is precisely what makes it so easy to misuse.

The two thresholds and the 21-day clock

Against a company the debt must be at least £750. That figure comes from section 123 of the Insolvency Act 1986 and, despite being temporarily lifted to £10,000 during the pandemic, it returned to £750 on 31 March 2022 and has stayed there. The form is SD1.

Against an individual the debt must be more than £5,000, the minimum for a creditor’s bankruptcy petition. A sole trader is an individual for this purpose, however commercial the invoice, so a £3,000 debt owed by a sole trader is below the line even though the same £3,000 owed by a limited company is comfortably above it. The form is SD2.

Either way the debtor has 21 days to pay, secure or compound the debt. “Compound” simply means reach an agreement you accept, so a payment plan you sign up to stops the clock. Nothing happens automatically at day 22. The demand does not become a judgment, no bailiff appears, and nothing is registered against the debtor. All that changes is that you have acquired the right to spend a great deal of money on a petition.

Why it works when it works

For a solvent company that is simply paying you last, a statutory demand is genuinely powerful, and the reason is banking rather than law.

A winding-up petition, once presented and advertised, is public. Banks monitor for it. The practical consequence is that a company facing an advertised petition can find its accounts frozen, because any disposition of the company’s property after the petition is presented is void unless the court validates it. A finance director who would happily ignore a fourth chaser will not ignore something that can stop the payroll running.

That leverage is real, and it is why the demand often gets paid inside the 21 days without a petition ever being presented. But notice where the leverage comes from: the debtor’s belief that you will actually petition. Against a debtor who knows you will not, a statutory demand is just an expensive-looking letter.

Why it backfires: three expensive ways

The debt turns out to be disputed

This is the big one. The insolvency process is not for deciding whether money is owed; it is for dealing with people who cannot pay money that is plainly owed. Use it to force a decision on a contested invoice and the court will take it badly.

An individual can apply to set the demand aside, normally within 18 days of service, and the 21-day clock is suspended while that application is pending. A company cannot apply to set a demand aside at all, which surprises a lot of creditors. It applies instead for an injunction restraining you from presenting or advertising a petition. Either way, if the debtor shows a substantial dispute or a credible cross-claim, you are likely to lose and to pay their costs, sometimes on the indemnity basis.

The bar is low for them and high for you. The debtor does not have to prove the dispute is right, only that it is genuine and substantial. So if your debtor has ever threatened a counterclaim, queried the quality of the work, or claimed a set-off, a statutory demand is the wrong instrument. A court claim is the right one, because deciding disputes is exactly what that process is built for.

You are not actually willing to petition

Presenting a winding-up petition currently costs a £302 court fee plus a £2,600 deposit for the Official Receiver, both payable up front. If no winding-up order is made, because the debt gets paid or the petition is dismissed, £2,550 of that deposit comes back, so the irreducible cost of a petition that works is a little over £350 plus whatever you spend on advice and service, and the sum you must have in cleared funds on day one is roughly £2,900 either way.

That arithmetic quietly rules the tool out for most small invoices. Threatening to spend £2,900 to recover £900 is not a threat a well-advised debtor takes seriously, and a demand you never follow through on does lasting damage: it tells the debtor, in writing, that your deadlines are decorative. If you would not really petition, do not really demand.

You win and still get nothing

Winding up a company does not pay you. It appoints a liquidator, who gathers the assets and distributes them in a strict order: fixed-charge lenders, the costs of the insolvency, preferential claims, floating-charge lenders, and then the unsecured pool, where your invoice sits alongside everyone else’s. Ordinary trade creditors routinely see pennies in the pound, and often nothing.

So a petition that succeeds against a company with no assets converts a recoverable debt into an unrecoverable one, at your expense, while also destroying any prospect of the debtor trading its way back to paying you. Check the filed accounts and any registered charges before you spend anything. If the company is already heading for strike off or insolvency, your problem is a different one with different answers.

What most creditors should do instead

For the great majority of unpaid invoices, the honest ranking runs: chase properly, then a letter before action that quantifies interest and compensation, then either a collection agency or a court claim depending on whether the debt is disputed.

That is not timidity. A debt that is undisputed and owed by a solvent business usually gets paid at the letter-before-action stage or shortly after an agency picks up the phone, at a fraction of the cost and none of the risk. Agencies also do the thing creditors most often skip, which is establishing whether the debtor can pay before anyone spends money on process. Where the debt is genuinely disputed, litigation is the correct route and insolvency is the wrong one. And if the invoice is old, check how long you have left to chase it before choosing any route at all.

Keep the statutory demand for the case it was built for: a clean, undisputed, comfortably above-threshold debt owed by a debtor who can pay and is choosing not to, where you are genuinely prepared to petition.

Scotland and Northern Ireland

Corporate insolvency runs UK-wide under the Insolvency Act 1986, so a statutory demand against a company works in broadly similar terms in Scotland, though petitions go to the Scottish courts. Personal insolvency is different: Scotland uses sequestration, administered by the Accountant in Bankruptcy, with its own procedure and thresholds, and the ordinary route to enforcement is a charge for payment following a decree. Remember too that Scotland’s five-year prescription period extinguishes a debt rather than merely barring the remedy, so an old invoice may simply be gone. Northern Ireland has its own insolvency legislation and its own forms, with proceedings in the High Court in Belfast.

The short version

A statutory demand is a precision instrument that creditors reach for as a blunt one. It is free to send, which flatters it, and it is backed by consequences severe enough that using it on a debt the debtor can argue about is a good way to end up paying their legal bill.

Ask three questions before you serve one. Is the debt genuinely beyond argument? Can the debtor actually pay? Would I really spend £2,900 to force the point? Three yeses and it is a strong move. Any no, and something cheaper will serve you better.

If you would rather find out what a professional would do with your debt before committing to anything, comparing costs nothing. On Collect Compare you can compare vetted UK debt recovery agencies blind, with names hidden until you choose, or let us match you to the right one. It is free for creditors: the agency you choose pays for the introduction, and no agency can pay to rank.
