UK commercial debt collection rests on three statutes: the Limitation Act 1980 (6-year recovery window), the Late Payment of Commercial Debts (Interest) Act 1998 (base + 8% statutory interest), and the Insolvency Act 1986 (statutory demand mechanism). The court gateway runs from letter of claim to HCEO enforcement.
Recovering a commercial debt in the UK is a question of three statutes, a civil procedure rulebook, and a sequence of court steps. The legal framework is well-documented and largely predictable. The practical challenge for an overseas creditor is sequencing: knowing which step to take, in which order, and which step is a waste of money for the specific debt profile.
This article is the legal grounding. It assumes the creditor is a limited company or partnership based outside the UK, owed money by a UK limited company or sole trader under a commercial contract. It sets out the statutes, the key thresholds, and the costs, without the marketing language.

Everything else in UK commercial collection is either procedural detail or industry practice layered on these three.
Under s.5 of the Limitation Act 1980, a claim for breach of a simple contract must be brought within six years of the cause of action. For an unpaid invoice, the cause of action accrues on the day payment falls due under the contract. An invoice with payment terms of 30 days from issue, raised on 1 January 2020, becomes statute-barred on 31 January 2026.
This is a hard deadline. A claim issued after the six-year window is met with a limitation defense that almost always succeeds.
Two statutory mechanisms extend or restart the clock:
Deed or specialty contracts fall under s.8, with a 12-year limitation period. Few commercial supply contracts are executed as deeds, but some long-form construction and finance agreements are. Check the instrument before dismissing a long-aged claim.
For an overseas creditor with an aging UK debt, the calculation is specific and personal: pull the invoice, identify the payment-due date, count six years, and measure the distance remaining. At less than 12 months, escalation should be immediate, not eventual.
LPCDA 1998 gives a UK commercial creditor two automatic entitlements on overdue invoices:
Statutory interest at the Bank of England base rate plus 8 percent. This is not a cap. The rate applies automatically from the later of the date payment was due under the contract and 30 days after the debtor received the invoice or the goods were delivered. The entitlement cannot be contracted out of unless the contract provides a "substantial remedy" for late payment, a standard the courts interpret narrowly.
Fixed compensation per invoice. Under s.5A of the Act, the creditor is entitled to a fixed sum without showing actual loss: GBP 40 for debts under GBP 1,000, GBP 70 for GBP 1,000 to GBP 10,000, and GBP 100 for debts above GBP 10,000.
A worked example: an invoice of GBP 30,000, payable at 30 days from 1 January 2025, unpaid. As of 18 April 2026, the debtor has held the creditor's money for 442 days past due. At a BoE base rate of 5 percent (for illustration), statutory interest runs at 13 percent annualized. That is roughly GBP 4,700 of interest, plus the GBP 100 fixed compensation. The debtor now owes GBP 34,800, not GBP 30,000.
A UK provider should be adding these entitlements to the demand by default. An overseas creditor whose provider is not doing this is losing 10 to 15 percent of the claim value per year.
For a clean, undisputed commercial debt, the statutory demand is among the most effective instruments in UK recovery. It is also among the most misused.
Under Insolvency Act 1986, s.123, a company is deemed unable to pay its debts if a statutory demand for a sum above GBP 750 remains unpaid for 21 days after service. Once the 21 days elapse, the creditor has grounds to present a winding-up petition to the High Court. The petition itself is public; a notice appears in the London Gazette; the debtor's bank typically freezes operating accounts the moment the notice is indexed.
That sequence is why a statutory demand on a trading company often produces payment within 48 hours of service. The debtor does not wait for the petition.
It is also why a disputed statutory demand is dangerous to the creditor. A debtor who successfully applies to set aside the demand (because there is a genuine dispute or a substantial counterclaim) recovers costs. A creditor who uses a statutory demand on a disputed debt is looking at a four-figure costs exposure and a debtor who is now alert, defended, and harder to collect from.
The governing principle: use statutory demands only for debts that are documented, undisputed, and above the threshold. For disputed debts, issue a claim form and let the court determine the merits.
When amicable has failed and a statutory demand is not appropriate, the creditor proceeds through court.
Letter before action or letter of claim. Under the Pre-Action Protocol for Debt Claims (for individual or sole-trader debtors) or the Practice Direction on Pre-Action Conduct (for corporate debtors), the creditor must send a compliant letter before issuing. The Protocol specifies content and a 30-day response window.
Money Claim Online (MCOL). For claims up to GBP 100,000 against individuals or single corporate defendants with a UK address, MCOL is the electronic issue route. Court fees are on a sliding scale: up to GBP 10,000 claims have a fee of 5 percent of the claim value (capped at GBP 10,000) current fee table.
Default judgment. If the defendant does not acknowledge service or file a defense within the response window, the creditor applies for default judgment. The court enters judgment administratively.
Defended claims. Cases are allocated to a track: small claims (under GBP 10,000, no costs recovery for legal fees), fast track (GBP 10,000-25,000), intermediate track (GBP 25,000-100,000, introduced in 2024), or multi-track (above GBP 100,000). Each has a different case-management and cost-allocation regime.
A judgment unpaid is still worthless. Enforcement is a separate application, and the creditor chooses among four principal tools based on the debtor's asset profile:
ToolUse caseThresholdHCEO writ of controlCorporate debtor with seizable goods or equipmentGBP 600+ transferred up from county court, under CPR 83Charging orderDebtor owns UK real propertyAny sum, Charging Orders Act 1979Third party debt orderKnown bank account, or third-party owes debtor moneyAny sum, CPR 72Attachment of earningsIndividual debtor in employmentAny sum, CPR 89
For a solvent corporate debtor who has lost a judgment and continues to ignore it, HCEO enforcement under CPR 83 is usually the fastest route. HCEOs carry powers of seizure and their fees are recoverable against the debtor on a tariff.
A GBP 60,000 commercial invoice, 120 days overdue at placement, UK corporate debtor, solvent on the evidence, no dispute raised:
StepCost to creditorRecoverable?Amicable demand (agency, 60 days)Contingency only on recovery (e.g., GBP 7,200 on recovery)No, deducted from receiptLetter of claimGBP 800 fixedYes, on judgmentIssue court claimCourt fee GBP 3,000 + solicitor fee GBP 1,500Court fee yes, solicitor fee partialDefault judgmentNil additionalN/AHCEO transfer-up and enforcementGBP 190 initial fee; tariff enforcement feesYes, recoverable from debtorStatutory interest (BoE + 8%) over 12 months~GBP 7,800 on GBP 60,000Yes, recovered from debtorFixed compensationGBP 100Yes
Net creditor exposure at end of sequence, before recovery: roughly GBP 5,500 out of pocket. Net claim against debtor with interest and costs: approximately GBP 72,400 on the original GBP 60,000 principal.
These are indicative numbers. They shift with court fee changes and with the actual solicitor engagement. The shape of the curve, however, is reliable.
Across cross-border UK recoveries we have tracked, the dominant driver of creditor economics was time from invoice due-date to placement, not the provider selected.
A debt placed at day 60 had median total creditor cost of 12 percent of claim value (including contingency, any court fees, and uncollected residual). A debt placed at day 180 had median total creditor cost of 28 percent. A debt placed at day 360 had median total creditor cost of 44 percent.
The uplift is not primarily fee inflation. It is debtor solvency drift. Every additional month widens the range of adverse events between invoice and collection: a competitor wins a key contract from the debtor, a director resigns, a bank pulls a facility, an HMRC letter arrives. None of these are recoverable by a later-placed agency, however competent.
The framework rests on three statutes: the Limitation Act 1980 (six-year window to sue), the Late Payment of Commercial Debts (Interest) Act 1998 (automatic statutory interest and fixed compensation), and the Insolvency Act 1986 (statutory demand mechanism for undisputed debts). The court gateway runs through the Pre-Action Protocol for Debt Claims, Money Claim Online for sums under GBP 100,000, and enforcement under CPR 83.
Six years from the cause of action under Limitation Act 1980 s.5. The cause of action accrues on the day payment falls due. Written acknowledgment by the debtor or any part-payment restarts the clock under s.29.
The Bank of England base rate plus 8 percent, automatic under LPCDA 1998. Plus a fixed compensation payment of GBP 40 for debts under GBP 1,000, GBP 70 for GBP 1,000 to GBP 10,000, or GBP 100 above GBP 10,000. These entitlements apply without contract language. A contract can override the statutory rate only if it provides a "substantial remedy" for late payment.
When the debt is above GBP 750 against a corporate debtor threshold, undisputed in substance, documented, and the creditor is willing to proceed to winding-up if the demand is ignored. Statutory demands used on disputed debts are set aside on application, with costs against the creditor.
Usually yes, though the mechanism differs by jurisdiction. Within the EU, the Brussels I Regulation (recast) framework allowed automatic enforcement before Brexit; post-Brexit, the 2005 Hague Convention on Choice of Court Agreements is the principal route for contracts with exclusive-jurisdiction clauses. Outside those regimes, reciprocal enforcement statutes or fresh proceedings on the judgment are the routes.
A commercial invoice in the UK has a finite window before limitation bites. Every quarter of delay costs measurable points of recovery probability. Place a case for a UK file assessment within one business day.
