6 Year Limit Checklist for Collecting Old Debts in the UK

Related Guides

 

Most simple contract debts become unenforceable through the courts after six years in England and Wales, and after five years in Scotland, under the Limitation Act 1980 and Scots prescription law. That doesn’t mean the debt vanishes; you can still ask for it, just not sue for it. A part-payment or a written acknowledgement from the debtor resets the clock, so your first move is to pull every invoice, contract, and message and check the dates before you do anything else.

TL;DR:

  • Debts in England and Wales become unenforceable after six years without action, while in Scotland the limit is five years, but the debt may still be requested.
  • A part-payment or written acknowledgment by the debtor resets the limitation period, making record-keeping crucial to assess enforceability.
  • Certain debts, like mortgage shortfalls, council tax, and court-judgment debts, follow different rules and require specific checks.
  • The process to recover enforceable debts involves initial reminders, formal demands, and possibly using statutory interest, with court proceedings as a last step.
  • Proper documentation and avoiding misleading practices are essential to prevent legal risks and ensure a possible successful recovery.

What “statute barred” or “prescribed” debt actually means

“Statute barred” is a specific legal state, not a vague expiry date. In England and Wales, the Limitation Act 1980 sets a six-year limitation period for most unsecured contract debts, running from the “cause of action”, usually the date payment fell due. Once that period passes without a court claim being started, a creditor loses the right to enforce the debt through the courts.

Scotland works on a different legal footing entirely. Rather than a limitation period, Scots law applies “negative prescription”, which after five years extinguishes the underlying obligation itself, not just the right to sue on it. That distinction matters for anyone dealing with Scottish debtors, and it’s covered in more detail further down.

Here’s the part people get wrong most often: statute barred does not mean written off. StepChange explains that a creditor can still write to a debtor and ask for payment after the limitation period expires. The debtor simply has a full legal defence if the creditor tries to take it to court. Many people pay statute barred debts anyway, either because they don’t realise the defence exists or because they’d rather clear it than have it sitting on their conscience or their credit file.

Not every debt runs on the same clock. Some categories sit outside, or partly outside, the standard six-year rule:

  • Mortgage shortfall debts, where limitation periods can run longer depending on the type of claim.
  • Council tax arrears, which local authorities recover through a different statutory process rather than an ordinary contract claim.
  • Debts already confirmed by a court judgment, which typically get a fresh limitation period of their own.
  • Secured debts, such as those tied to a charge over property, which follow separate rules again.

If a debt falls into one of these categories, check Gov or take specific advice rather than assuming the standard six-year rule applies.

When does the clock start, and what resets it?

The starting point for most unsecured commercial or personal debts in England and Wales is straightforward: six years from the date payment became due, whether that’s an invoice due date, the date of a breach of contract, or the date a loan agreement specified for repayment. Scotland’s prescriptive period runs five years from broadly the same kind of trigger event.

What complicates things is that the clock doesn’t always run cleanly to zero. Two things restart it:

  • A part-payment. Any payment, even a small one, made by the debtor towards the debt after it fell due resets the limitation period from the date of that payment.
  • A written acknowledgement. A signed letter, an email, or any written communication from the debtor accepting the debt exists and is owed also restarts the clock.

This is why record-keeping matters more than most creditors realise. Commentary on the Limitation Act 1980 makes the point plainly: a single email reply from a debtor saying something like “I know I owe this, I’ll sort it next month” can be enough to reset a six-year period that was about to expire. The kinds of records worth hunting for include:

  • Bank statements or ledger entries showing partial payments and their dates.
  • Email threads, text messages, or letters where the debtor references the debt.
  • Signed payment plans or informal repayment agreements, even unofficial ones.
  • Call notes or contact logs recorded at the time, not reconstructed from memory later.

Checking whether an old debt is still enforceable: a practical checklist

Before you write to anyone, work through this sequence methodically. Rushing this step is how creditors accidentally undermine their own case or, worse, breach the debtor’s rights.

  1. Gather every document. Invoices, the original contract or terms of business, payment ledgers, and all correspondence, including anything informal.
  2. Calculate the key date. Identify exactly when payment became due, then count forward six years (five in Scotland) to find your limitation deadline.
  3. Search for anything that resets the clock. Look specifically for part-payments after the due date or any written acknowledgement of the debt, however casual.
  4. Identify the debtor type. A consumer, a sole trader, and a limited company follow different procedural paths, and the Pre-Action Protocol for Debt Claims applies differently depending on which one you’re dealing with.
  5. Decide whether to pause before writing. If you’re close to the limitation deadline and unsure whether contact might trigger an unintended acknowledgement from your side rather than theirs, get advice first.

That last point catches people out. A poorly worded letter that implies you’re treating the debt as still live can complicate your own position if the debt is genuinely time expired.

Pro Tip: Before sending any letter on a debt older than four years, date stamp your entire evidence file and store it separately from ongoing correspondence. If the case ever reaches court, a tidy timeline is worth more than any amount of persistence.

Practical recovery steps for older but still enforceable debts

If your calculations show the debt is still within the limitation period, the recovery path is fairly standard, but the order and tone of each step matters, especially with older debts where memories and paperwork have faded.

Start with a polite but firm reminder. This isn’t the moment for threats. A short, factual note referencing the original invoice number, the amount, and the due date often gets more traction than people expect, particularly with individuals who’ve simply lost track of an old bill. If that goes nowhere, move to a formal final demand or letter before action. This needs to include the amount owed, how it’s calculated, a clear deadline for payment, and a statement of what happens if payment isn’t made. Debt Recovery Hub’s guide to letters before action sets out the specific wording that England and Wales courts expect to see before a claim is issued.

For business-to-business debts, there’s a lever many creditors forget about. Under the statutory late payment regime, qualifying commercial debts can attract statutory interest and fixed compensation on top of the principal sum, calculated from the day after the payment due date. Adding this to your demand does two things: it increases the amount owed, and it signals to the debtor that you know the process properly, which alone prompts some businesses to settle rather than test your resolve.

A few practical points worth holding onto through this stage:

  • Keep every reminder and demand letter dated and saved, even the ones sent by email.
  • Never threaten action you don’t intend to take. Empty threats damage your credibility and can create legal risk of their own.
  • If the debtor disputes the debt, note the dispute and the date. It affects your evidence trail either way.
  • Where the limitation deadline is close, don’t wait for a “final” final demand. Issue the court claim in time rather than losing the right to sue over a fortnight’s delay.

Once reminders and demands have failed, decide whether to instruct a professional collector or a solicitor. For complex, high-value, or long-overdue debts, a specialist saves time precisely because quick enforcement and knowing where the debtor’s assets are held matters more than winning the judgment itself. Give them the full case file: the original contract, every invoice, the full correspondence trail, and your limitation calculation, so they can assess enforceability from day one rather than discovering a problem halfway through.

If you’d rather not manage the reminder and escalation stage yourself, Debt Recovery Hub’s guide for small businesses on recovering unpaid invoices walks through the same sequence with sample wording for each stage.

Pre-action protocol and taking a debt to court

Before issuing a claim against an individual in England and Wales, the Pre-Action Protocol for Debt Claims usually applies, and skipping it is a common way creditors damage their own case, even when the debt itself is sound. The protocol requires a Letter of Claim setting out the debt, an Information Sheet explaining the debtor’s options, and a Reply Form, giving the debtor a minimum of 30 days to respond before you can issue proceedings. Courts can penalise creditors on costs for ignoring this step, even where the underlying claim succeeds.

Where the protocol doesn’t strictly apply, such as most business-to-business claims, it’s still sensible practice to send an equivalent letter before action. It shows good faith and often prompts payment without a claim ever being issued.

Pre-action protocol and taking a debt to court — overview diagram

Once you’re ready to sue, Money Claim Online (MCOL) is the standard route for claims up to £100,000 in England and Wales. After issuing, the defendant has 14 days to acknowledge the claim, and a further 14 days beyond that to file a defence if they’ve acknowledged. If they do nothing at all, you can apply for default judgment, which can arrive within a matter of weeks on an undefended claim.

Track allocation shapes how much the process costs and how long it drags on:

  • Small claims track covers most claims up to £10,000 and keeps costs recovery limited, which suits straightforward, low-value debts.
  • Fast track applies to higher-value claims with a trial expected to last under a day, with more formal case management.
  • Multi-track handles complex or high-value disputes, typically where the facts or the sums involved justify a fuller court process.

For most old, straightforward debts under £10,000, small claims is where you’ll end up, and it’s designed to be navigable without a solicitor. Above that, or where the debtor is likely to dispute the claim seriously, professional help earns its cost quickly.

Enforcement after judgment: what actually gets you paid

Winning a judgment and actually seeing the money are two different things, and this is where a lot of creditors get a rude surprise. A default judgment confirms the debt is owed. It doesn’t move a single pound out of anyone’s account. Enforcement is the step that does that, and which tool you use depends heavily on what you know about the debtor’s finances.

  • County court bailiffs can seize goods to sell at auction, suited to smaller judgments where the debtor has visible, sellable assets.
  • High Court Enforcement Officers (HCEOs) handle larger judgments (usually transferred up from the county court) and tend to move faster and more assertively than county court bailiffs.
  • Third-party debt orders freeze funds held by a third party, most commonly the debtor’s bank account, once you know which bank they use.
  • Charging orders secure the debt against property the debtor owns, useful for homeowners but slow, since you often need a further order to force a sale.
  • Attachment of earnings orders deduct fixed amounts directly from an employed debtor’s wages, which only works if you know their employer.
  • Statutory demands and insolvency routes apply pressure on debts above the statutory threshold, potentially pushing an individual towards bankruptcy or a company towards winding up, though this is a serious step reserved for debtors who can genuinely pay but won’t.

The barrier most creditors hit isn’t the law, it’s information. You can win judgment against someone with no known bank account, no known employer, and no property in their name, and be left holding a piece of paper worth nothing in practice. Overseas debtors compound this further, since UK enforcement tools generally can’t reach assets held abroad without additional, often costly, legal steps. This is precisely where a specialist collector earns their fee: locating assets before you spend money enforcing against nothing.

Scotland: the five-year prescriptive period and what’s different

Scotland doesn’t run on limitation, it runs on prescription, and the practical effect is sharper than the English rule. Negative prescription extinguishes the obligation itself after five years, not merely the right to sue on it. Once a debt prescribes in Scotland, it is, in the fullest legal sense, gone.

Recent reform has tightened how the “discoverability” of a debt is assessed, meaning the point at which a creditor reasonably ought to have known about the debt now carries more weight in calculating when the five years actually starts. That makes contemporaneous evidence even more valuable north of the border than it already is in England and Wales.

Practical steps for creditors dealing with Scottish debtors:

  • Confirm the debtor’s residence and where the contract was formed, since this affects which jurisdiction’s rules apply.
  • Treat any part-payment or written acknowledgement as urgent evidence to record immediately, given how firmly prescription bites once it runs.
  • Take Scotland-specific legal advice rather than assuming English limitation rules transfer across, because they don’t.
  • Act promptly on any debt approaching four years old rather than waiting until the fifth year to review the file.

Deciding when to stop chasing a debt

Not every old debt is worth pursuing, and recognising that early saves more money than any recovery tactic. Three signals usually mean it’s time to stop: the debt is genuinely statute barred with no acknowledgement or part-payment to revive it, the debtor is insolvent or has been through bankruptcy proceedings covering the debt, or the likely cost of recovery, court fees, enforcement fees, professional time, simply exceeds what you’d realistically collect.

When you do write a debt off, document the decision properly. Record the amount, the last payment or acknowledgement date, your limitation calculation, and the specific reason for writing it off. This matters for two audiences: your accountant, who needs it for bad debt relief calculations, and any future auditor who might ask why a debt disappeared from the books. For large sums, take tax advice before writing anything off; VAT bad debt relief and corporation tax treatment both have specific conditions attached that are easy to miss if you’re moving quickly to clear the books.

How Debtrecoveryhub and DebtCollect.org fit into recovering old debts

If your evidence check shows a debt is still enforceable, the next decision is who actually chases it. A matching model asks for the case details that matter, the debt type, the amount, its age, and the debtor’s location, then connects you with vetted UK collection agencies suited to that specific profile rather than a generic list.

Before starting an assessment, gather the same file you’d need for court anyway: the original invoice or contract, a clear payment history, and copies of any communications, especially anything showing a part-payment or acknowledgement. DebtCollect.org uses those upfront details to remove the guesswork of picking an agency blind, which matters most on older debts where the wrong collector wastes weeks re-establishing facts you already have. That upfront detail is also what increases the odds of a professional, properly handled recovery rather than a rushed one.

Keeping records that actually hold up later

The single biggest weakness in most collection files isn’t the debt, it’s the paperwork. Invoices go unfiled, emails get deleted during inbox cleanups, and payment records live in three different systems that don’t talk to each other. None of that matters until you need to prove a date in court, and then it matters enormously.

Store every invoice with its issue date, due date, and any amendments clearly logged, ideally in a system that timestamps changes rather than a spreadsheet anyone can edit silently. Keep correspondence, letters, emails, texts, in its original form rather than summarised notes; a paraphrased “customer said they’d pay” is worth far less than the actual message. Log every payment against the specific invoice it relates to, not just against the account generally, since part-payment against a specific debt is what resets limitation, not a vague payment on account.

Illustration of organized debt evidence records

Landlords chasing rent arrears face a particular version of this problem, since tenancy paperwork often scatters across letting agents, previous landlords, and informal messages. Landlord Compliance’s guidance on preserving invoices and correspondence covers what to keep and for how long, which is worth reviewing before you assume your records are court ready. Whatever the debt type, review your filing system annually, not just when a dispute forces you to.

UK debt collection law protects debtors from specific, well-defined bad behaviour, and breaching it turns a straightforward recovery into a liability. Harassment, contacting a debtor at unreasonable hours, repeated unwanted calls, or contacting them at work after being asked not to, can expose a creditor to complaints and, in serious cases, action under harassment legislation.

Misrepresenting the debt is another common trap: overstating the amount owed, implying court action is imminent when none is planned, or suggesting bailiffs will attend when no judgment exists. Each of these can amount to a misleading or unfair practice, and debtors who complain to trading standards or the Financial Conduct Authority (where regulated activity is involved) can cause real reputational and financial damage to the creditor, not just the collector.

Contacting the wrong person is a quieter but equally serious risk. Chasing someone who shares a name with the actual debtor, or continuing to pursue someone after they’ve provided evidence the debt isn’t theirs, can amount to harassment even when unintentional. Verify identity properly before escalating, not after a complaint arrives.

Finally, pursuing a debt you know is statute barred while implying it’s still legally enforceable is misleading conduct. You’re allowed to ask for payment. You’re not allowed to threaten court action you have no legal right to bring.

Alternatives to court: mediation and repayment plans

Court isn’t the only route, and for debts where the relationship or the debtor’s circumstances matter, it’s often not the best one. Mediation brings both sides together with a neutral third party to agree a resolution, usually faster and cheaper than litigation, and it works particularly well where there’s a genuine dispute about the amount owed rather than simple non-payment.

Where the debtor genuinely can’t pay in one go but isn’t disputing the debt, a structured repayment plan agreed directly, or through a debt management plan the debtor arranges with a free advice charity, often gets more money back over time than an aggressive court push that ends in an unenforceable judgment against someone with no assets. National Debtline and StepChange both help debtors set these plans up, and creditors who cooperate with a formal plan usually see steadier, more predictable payments than those who refuse and push straight to court.

The trade-off is time. A repayment plan might take two or three years to clear a debt that a successful court claim could, in theory, recover faster. But “in theory” is the key phrase: a judgment against someone with no spare income or seizable assets is often worth precisely nothing.

Credit scores and why they change debtor behaviour

Defaults and County Court Judgments (CCJs) show up on a debtor’s credit file for six years, and that visibility changes how people respond to a demand letter far more than most creditors expect. Someone who might ignore three reminder emails often responds within days of a letter that clearly states a CCJ is the next step, simply because a poor credit file affects mortgage applications, car finance, and even some job checks.

This gives creditors a genuinely useful, low-cost lever: explaining, factually and without exaggeration, what a CCJ means for the debtor’s credit file is often more persuasive than a threat of enforcement action itself. It’s also why acknowledging a debt in writing, even an informal “I’ll pay next month” message, is something debtors sometimes avoid instinctively once they understand it resets the limitation clock. Creditors who explain this plainly, rather than relying on vague pressure, tend to get more useful written responses.

Chasing a business versus chasing an individual

The legal process changes meaningfully depending on whether you’re pursuing a limited company, a sole trader, or a private individual, and treating them the same is a common mistake.

Debts owed by limited companies benefit from statutory interest and fixed compensation under the late payment regime in a way consumer debts don’t, and a company that ignores a winding-up petition risk tends to move faster than an individual facing the same pressure, since insolvency threatens the business’s survival. Company debts also come with a public paper trail, Companies House filings, registered addresses, and director details, that make identifying the right party and serving documents considerably easier than tracking down an individual who’s moved house.

Sole traders sit in an awkward middle ground: legally, the business and the individual are the same person, so personal assets are exposed, but the Pre-Action Protocol for Debt Claims typically applies to them in the same way it applies to consumers, unlike limited companies. Individuals, meanwhile, get the full protection of consumer-facing rules, including the protocol’s Letter of Claim and Reply Form requirements, and creditors chasing them need to tread more carefully around communication frequency and tone than they would with a corporate debtor.

Balancing recovery with commercial relationships

The instinct to escalate immediately often costs more than it recovers. One recurring pattern worth noting: businesses that offer a modest, time-limited discount for immediate payment on an aged invoice often recover faster, and keep the customer, than those who go straight to a solicitor’s letter.

Start a free assessment for your outstanding debt

Chasing an old invoice or a stubborn client balance alone means guessing which collector actually specialises in your kind of case, an aged commercial debt, a cross-border customer, or a complicated dispute where the paperwork is thin. Debtrecoveryhub is the alternative to picking blind: instead of cold-calling agencies and hoping one fits, you submit the debt type, amount, age, and location once, and get matched with vetted UK collectors suited to that exact profile.

Debtrecoveryhub

This works best for debts that are older but still within the limitation period, complicated B2B balances with statutory interest attached, or cases involving a debtor abroad where you need a collector who’s actually handled that before. The assessment itself is free and takes a few minutes: gather your invoice dates, contract, and any correspondence first, then start the debt collection assessment to get matched with the right agency for your case rather than the first one you find searching online.

FAQ

Can a 10-year-old debt still be collected in the UK?

You can still ask for payment on a debt that old, but if no court claim was started and there’s been no part-payment or written acknowledgement within the last six years (five in Scotland), it’s statute barred and unenforceable in court.

Can a debt from five years ago still be collected?

Yes, in England and Wales a five-year-old debt is almost always still enforceable, since the limitation period is six years from the due date; in Scotland, five years is the cut-off, so it depends on exactly when the debt fell due.

Yes, debt collection is legal, provided it follows the correct process, including the Pre-Action Protocol for Debt Claims where it applies, and avoids harassment or misleading statements about enforcement action.

What happens if my debt is over six years old?

If no court claim was issued and nothing reset the clock, the debt becomes statute barred and a creditor can no longer successfully sue for it, though StepChange notes it isn’t automatically written off and can still be requested.

Does a part-payment restart the limitation period?

Yes. Any part-payment made after the debt fell due, or a written acknowledgement from the debtor, resets the six-year clock in England and Wales (five years in Scotland) from the date of that payment or acknowledgement.
