Prescription extinguishes the obligation itself. Limitation in England and Wales bars the remedy instead, which is a different thing entirely.

That distinction reframes everything below. Here is what the 1973 Act says, which debts sit on which period, what extinction does, and what to do about a very old balance the council is still chasing.

Strictly, nothing. Statute barred is English usage, and the Scots law equivalent is prescribed, which comes from the Prescription and Limitation (Scotland) Act 1973.

Prescribed, not statute barred

A prescribed debt has been extinguished by the passage of time. Advisers in Scotland use that word because it is what the statute does to the obligation.

The 1973 Act sets two periods. Section 6 gives the short negative prescription of five years, and section 7 gives the long negative prescription of twenty years.

Extinguishing an obligation is not the same as barring a remedy

Prescription ends the obligation. Once it has genuinely run there is no debt sitting behind the creditor’s inability to collect, because the thing itself has gone.

Limitation in England and Wales operates on the remedy instead, which is why guidance written there talks about a creditor being unable to enforce. The phrase carries that idea with it when it is applied to a Scottish debt.

Why the wrong word costs people money

If you treat a council tax balance as dead at five years, the letters stop making sense. The balance is still live and still enforceable by diligence.

Most consumer debts sit on the five-year short negative prescription under section 6. Council tax, non-domestic rates and their associated charges sit on the twenty-year long negative prescription under section 7.

The two periods side by side

The five-year rule is real and genuinely useful on old consumer debt. It simply is not the rule for council tax.

What the five-year rule covers

Under section 6 a credit card, loan, overdraft or catalogue balance is extinguished if there has been no relevant claim, no payment and no written acknowledgement for five years. It is the rule that does not reach council tax.

What this means for a mixed set of debts

A household with arrears can have both types. An old catalogue balance and an old council tax balance from the very same year are in different legal positions.

That is a good reason to have the whole list checked by an adviser rather than treating every line on it the same way.

Because Schedule 1 paragraph 2(fd) of the 1973 Act excludes it in terms. The exclusion covers council tax under Part 2 of the Local Government Finance Act 1992, non-domestic rates, and the associated surcharges, fees and enforcement expenses.

The power to charge and collect council tax comes from the Local Government Finance Act 1992, and the recovery machinery sits in the Council Tax (Administration and Enforcement) (Scotland) Regulations 1992. Paragraph 2(fd) names that statute, which is why the exclusion leaves little room for argument.

The tail of the exclusion is the part that catches people out

The 10% surcharge added when a summary warrant is granted is an associated surcharge. The sheriff officer fees added to your balance afterwards are associated fees and expenses.

So there is no argument that the tax is old but the charges are newer. Sheriff officer fees are set by the court and added to what you owe, and paragraph 2(fd) puts them on the same twenty-year period as the tax.

Non-domestic rates sit alongside council tax

The same paragraph catches non-domestic rates, and the same 10% surcharge applies to rates on grant of a summary warrant. A business ratepayer is on the twenty-year period too.

Extinction ends the obligation, so there is nothing left for a creditor to pursue, revive or ask you to acknowledge. That is a stronger outcome than a creditor simply losing the ability to sue you.

What extinction does

The obligation ceases to exist rather than becoming unenforceable. There is no dormant balance waiting to be reactivated by a phone call or a payment.

That is why the timing matters so much. A council tax balance one day short of the twenty years is a live debt, enforceable in full.

What extinction does not do

It does not mean the bill was wrong. Prescription is about time passing without a relevant claim, payment or acknowledgement, not about whether you were liable in the first place.

And it does not happen because a council has gone quiet for a while. Silence only counts if it runs the whole period with no relevant claim in it.

What to do if collection carries on anyway

Take advice before you pay or agree the balance in writing, because on a five-year consumer debt both send the period back to the start. Ask the council for a year-by-year breakdown of the account and take it to a free money adviser.

Whether prescription has run turns on dates on one particular account. Our council tax debt advice page covers how to put that request to a council.

If a wage arrestment has already started on a balance you believe is extinguished, raise that with an adviser rather than with your payroll department.

It depends which period applies. On the five-year period a relevant claim, a payment or a written acknowledgement each send it back to the start, while on the twenty-year period only a relevant claim matters and it extends the period rather than restarting it.

Diligence counts as a relevant claim

Section 9 treats executing any form of diligence as a relevant claim. An earnings arrestment, a bank arrestment or an attachment of goods under the Debtors (Scotland) Act 1987 is a relevant claim on that wording.

Enforcement does not send the clock back to the start. Since 28 February 2025 a relevant claim, which includes executing diligence, extends the twenty-year period until that claim is finally disposed of.

Before that date it restarted the period, and a great deal of published advice has not caught up.

A summary warrant has no expiry written into it either. An earnings arrestment under one falls with the employment if you leave that job, and the creditor then has to trace your new employer and serve a fresh arrestment schedule.

A payment no longer touches the twenty-year period

A payment or a written acknowledgement does not affect the twenty-year period at all. Section 10(1) of the 1973 Act now applies only for the purposes of sections 6 and 8A, and section 7 is not among them, so acknowledgement has no part in the twenty-year rule.

The five-year rule is different and has not changed. Under section 6 a payment or a written acknowledgement still interrupts the period and sends it back to the start, which is why the advice to take advice before paying an old debt still holds for ordinary consumer debt.

The events that touch each clock, and the ones that do not

Those two columns are about prescription only, not about whether a council will chase you. Council tax sits in the right-hand column, and most consumer debt in the middle one.

Who has to prove the obligation survived

Section 13A, inserted on the same date, puts the burden on the creditor. Where a question arises about whether an obligation has been extinguished, it is presumed to have been extinguished unless the creditor proves otherwise.

That is a genuinely useful point on an ancient balance, because it is not for you to prove the debt has gone. It is still worth getting the dates read properly before anyone relies on it.

From the date the obligation became enforceable, on the wording substituted into section 7(1) on 28 February 2025. This article will not give you a date, because the starting point turns on the billing and recovery history of the particular account.

Why no page should hand you a date

Real accounts are messy. Bills get reissued, liability periods amended, payments allocated across years, and a summary warrant granted somewhere along the way.

A council tax account passes through a reminder and a final notice before a council applies for a summary warrant. When the twenty years began on your own account is a question for its billing and recovery history rather than for a rule of thumb.

Be wary of any page that hands you a clean trigger date. A money adviser reading the real history is the reliable answer.

Why twenty years is not a plan

Once a summary warrant is granted the balance stays enforceable. The warrant power in Schedule 8 paragraph 2 of the Local Government Finance Act 1992 has no time limit, no duration and no expiry.

None of that makes an old council tax balance safe to ignore. Twenty years is a long period, the council does not need to sue you to enforce, and a live claim holds the period open.

So prescription is worth checking on an ancient balance and is not a plan for a debt from a few years ago. An arrangement or a formal debt solution is the realistic route.

If the council reaches your wages first, deductions come off net pay under Schedule 2 to the 1987 Act, on the tables in force since 6 April 2025. That is £172.50 a month on net monthly pay of £1,800.00, and our wage arrestment calculator works out your own figure.

Ask the council in writing for a breakdown by financial year, and take it to a free money adviser before you pay or acknowledge anything. If the debt stands, deal with it as a debt rather than as a time-limit question.

What to ask the council for

• The property, and the dates you were treated as liable for each year.
• Every payment received, and how each one was allocated between years.
• Every charge added, including the 10% surcharge and any sheriff officer fees.
• The date any summary warrant was granted, and what diligence has followed it.

Payments are normally allocated to the oldest year of arrears first unless you specify otherwise. Put it in writing at the time if you want a payment credited to a particular year.

Our council tax billing guide explains how a bill and its instalments are put together.

If the debt stands and you cannot pay it

Ask the council for a special payment arrangement first. There is no statutory maximum period for spreading arrears, and councils commonly work to the current financial year while considering longer where affordability is shown.

Beyond that, an approved Debt Payment Programme under the Debt Arrangement Scheme freezes interest, fees and charges and stops an existing earnings arrestment. A protected trust deed ends one on the date of protection under s.173 of the Bankruptcy (Scotland) Act 2016.

Council tax arrears can go into a Debt Payment Programme. Your current-year liability cannot, so that still has to be paid alongside.

A moratorium while you decide

A statutory moratorium gives six months of protection and you get one per rolling 12 months. It stops service of a charge for payment, stops new diligence and stops creditor petitions for sequestration.

It does not stop a creditor obtaining a decree, and interest and charges keep accruing throughout.

It does not stop an earnings arrestment that was already running. Section 197(5)(d) of the Bankruptcy (Scotland) Act 2016 lets a creditor carry on executing an earnings arrestment, a current maintenance arrestment or a conjoined arrestment order that came into effect before the moratorium began.

It is applied for through the Accountant in Bankruptcy, usually via a money adviser. Money already deducted before a solution takes effect is credited against the debt rather than refunded.
