How to Pay Off Debt in the UK: £3,000 in 4 Years, Not 28
How to pay off debt in the UK without finding extra money: the same £85.72 a month clears £3,000 in 4 years 10 months, not 28. The maths and the apps.
Almost every guide to how to pay off debt in the UK opens by telling you to spend less. That advice is not wrong, it is just second. There is a change you can make in about four minutes, this evening, that costs you nothing extra in month one and still takes roughly £3,500 of interest off a typical credit card balance. It is a change to how your payment is collected, not how much you pay, and no budgeting app will make it for you.
This page works through that change, the maths behind it at the rate British cardholders are actually being charged in 2026, the legal duties your card company already owes you at 18 and 36 months, and the specific job money apps are good at once the boring part is done.
Falling interest rates have not reached your credit card
Start with the number the advice pages skip. The Bank of England publishes a monthly series called representative credit card lending to households, code IUMCCTL. It is the rate on the cards actually being marketed, and it has barely twitched while Bank Rate has fallen a full percentage point.
In January 2025 the representative rate was 24.65%. In July 2026 it was 24.71%. Over the same nineteen months, the monthly average of official Bank Rate went from 4.75% to 3.75%. The gap between what the Bank charges and what your card charges got wider by more than a point.
The practical reading: waiting for card debt to get cheaper is not a plan. Nothing in the last year and a half suggests it will. You can check both series yourself in the Bank of England interactive database.
The minimum payment is designed to shrink
Here is the rule almost nobody reads. The FCA’s Consumer Credit sourcebook, CONC 6.7.5R, says a firm must set the minimum required repayment on a credit card or store card “at an amount equal to at least that amount which repays the interest, fees and charges that have been applied to the customer’s account, plus one percentage of the amount outstanding”. It applies to agreements made on or after 1 April 2011.
Read that again with the emphasis in the right place. The minimum is a percentage of what you still owe. As the balance falls, the minimum falls with it. A direct debit set to “minimum payment” is a direct debit that gets smaller every single month, which is exactly why it never finishes.
Work it through on a £3,000 balance at 24.71%, the July 2026 representative rate, with no new spending on the card and the minimum set at the regulatory floor:
| Pay the minimum each month | Freeze the payment at £85.72 | |
|---|---|---|
| First month’s payment | £85.72 | £85.72 |
| Time to clear | 28 years 4 months | 4 years 10 months |
| Interest paid | about £5,360 | about £1,890 |
| Total paid | about £8,360 | about £4,890 |
Identical money leaves your account in month one. The difference is roughly £3,470 and 23 years, and it comes entirely from refusing to let the payment shrink. Many issuers set their minimum higher than the regulatory floor, which shortens the left-hand column, but the shape does not change: a falling payment stretches the debt.
The FCA has explicitly recognised this. CONC 6.7.34G confirms that a customer “increasing payments” includes the case “where the amount a customer pays remains fixed at the same amount the customer was previously paying”. Holding still counts as speeding up.
And you are entitled to do it. CONC 6.7.6R requires the card firm to “provide a customer with the option to pay any amount they choose (equal to or more than the minimum required repayment but less than the full outstanding balance) on a regular basis, when making automated repayments”. A fixed monthly direct debit of your choosing is not a favour. It is a rule.
Do this first. Open your card’s app, find the direct debit or recurring payment setting, and switch it from “minimum” to a fixed amount at least equal to this month’s minimum. Then leave it alone.
Your card company owes you a plan at 18 months, whether you ask or not
This is the part of UK debt rules that goes almost entirely unused, and it is worth knowing before you download anything.
Under CONC 6.7.27R, a card firm must check, at least once a month, whether over the preceding 18 months you have paid less towards principal than towards interest, fees and charges. If you have, you are in what the FCA calls persistent debt, and the firm must write to you, explain that paying more would cut the cost and the time, encourage you to get in touch, and give you the contact details of not-for-profit debt advice bodies. The one carve-out that matters: it does not apply if the balance dipped below £200 at any point in those 18 months.
Then the clock keeps running:
- Months 9 to 10 after that letter (CONC 6.7.29R): the firm must look at your payment pattern since, assume it continues, and if you are heading for a second 18-month period in persistent debt, write to you again.
- At 36 months (CONC 6.7.30R and 6.7.31R): if you were still paying more in interest than principal across the second 18-month period, the firm “must take reasonable steps to assist” you to clear the balance faster in a way that does not damage your finances. It has to set out options, which CONC 6.7.32G says can include a repayment plan or moving the balance to a fixed-sum personal loan, and give you a reasonable period to reply.
- The target it must aim at (CONC 6.7.33G): the FCA “expects a ‘reasonable period’ … to usually be between three and four years”, with anything beyond four years reserved for exceptional cases and at no extra cost to you.
There is a sting. CONC 6.7.35R says that if you do not respond, or you agree the options are affordable and then say you will not pay them, the firm must suspend or cancel your use of the card. Ignoring the letter is the one response with a guaranteed bad outcome.
Now put that next to the maths above. On our £3,000 example, paying the regulatory minimum means that after 18 months you have paid about £496 off the principal and about £922 in interest. You are in persistent debt by the FCA’s own test, automatically, from a balance most people would not describe as a problem. After three full years of paying every month you would still owe roughly £2,089.
If you have had a card balance sitting there for a couple of years, go back through your emails for a letter about your payments. It exists, and it is an offer of a three-to-four-year plan.
What money apps are actually for
Once the payment is fixed, the useful job left is finding the money to raise it, and that is genuinely what open banking apps do well. Be clear-eyed about what they do not do.
They do not order your debts for you. A lot of pages claim UK budgeting apps run avalanche or snowball calculations. Check the feature lists first-party before you believe it. Emma’s own site organises its product around everyday spending, budgeting, analytics, net worth, saving, cashback, payments, investing and credit score, plus rent reporting to Equifax, Experian and TransUnion. There is no debt payoff engine in that list. Snoop is built around spotting overpayment on bills and subscriptions. Both are extremely good at freeing up £30 or £60 a month. Neither will tell you which card to attack first, so do that on paper, once, in ten minutes.
Their strongest use is the redirect. The apps find leaks; a fixed payment turns a leak into progress. If cancelling forgotten subscriptions frees £22 a month, raise the standing order by £22 the same day. Money not immediately committed gets spent. On our £3,000 example, going from £85.72 to £115.02 a month clears the balance in three years flat and cuts total interest to about £1,140.
The blind spot is buy now, pay later. Connect every account you can, then write down the ones the app cannot see. Aggregators read payment accounts through open banking, which means BNPL instalment plans frequently sit outside the picture entirely, and a net worth figure that ignores them is flattering you.
That blind spot now matters more, because the sector changed on 15 July 2026, when the FCA began regulating deferred payment credit. The regulator’s own figures put the market at over £13bn in 2024, up from £0.06bn in 2017, with 10.9 million UK adults using it in the twelve months to May 2024. From regulation day you get upfront information about payment dates and what happens if you miss one, proportionate affordability checks before you borrow, a duty on lenders to support customers in difficulty and point them to free debt advice, and the right to take a complaint to the Financial Ombudsman Service. The FCA’s announcement sets all of it out. Merchant own credit, where a retailer lends to you directly, stays exempt.
For anyone paying off debt, the practical consequence is unchanged: interest-free BNPL sits at the bottom of any interest-ranked list, but a missed instalment is a missed credit commitment, so the payment date beats the interest rate on that one.
Ordering what you owe
Two methods, and the honest version of the argument:
Highest rate first (avalanche). List every debt by APR, pay the fixed minimum on all of them, and put every spare pound at the top of the list. It costs the least. At the rate gap we are looking at in 2026, with cards near 24.71% and almost nothing else close, the top of that list is nearly always a credit card or an overdraft.
Smallest balance first (snowball). Same idea, ordered by size. It costs slightly more and it clears whole debts sooner, which some people need to keep going. If you have abandoned two previous attempts, the more expensive method you finish beats the cheaper one you quit.
Three UK-specific adjustments that the generic version misses:
- Overdrafts belong at the top with the cards. They are often priced in the same band and they are invisible, because the balance simply looks like a smaller current account.
- A 0% balance transfer changes the order, not the debt. It is a genuinely useful move if you keep the payment fixed at the level that clears the balance before the promotional period ends. If you drop to the minimum on a 0% card you will arrive at the end of the deal with a balance and a standard rate.
- Priority debts are not on this list at all. Rent, mortgage, council tax, energy and anything with a court order behind it come first, whatever the interest rate, because the consequence of missing them is not a charge, it is losing your home or your supply.
Once you have the order, the apps you already use become the reporting layer: a budgeting app shows the spare pound arriving, and a credit score app shows the balances falling on your file.
When an app is the wrong tool entirely
If you are choosing between debts, or paying one card with another, or missing priority bills, no amount of transaction categorisation will help and free advice will.
Debt advice from StepChange, National Debtline and Citizens Advice is free, and the FCA requires the card firms above to point you to them by name. Beyond advice, England and Wales have a legal protection worth knowing about. Under the Debt Respite Scheme, a standard breathing space gives “legal protections from creditor action for up to 60 days”, pausing most enforcement action and creditor contact and freezing most interest and charges. A mental health crisis breathing space, for someone receiving mental health crisis treatment, “lasts as long as the person’s mental health crisis treatment, plus 30 days (no matter how long the crisis treatment lasts)”.
You cannot apply for it yourself. A debt advice provider or a local authority starts it, which is another reason the free advice call comes before the app store.
The four-minute version
- Switch every card and store card direct debit from minimum to a fixed amount, at least this month’s minimum. This is the step that does most of the work.
- Search your email for a letter from your card company about your payment pattern. If one exists, reply to it, because it is an offer of a three-to-four-year plan and ignoring it gets the card suspended.
- List everything you owe by interest rate, with overdrafts included and priority bills kept separate.
- Connect your accounts to a budgeting app to find spare money, then raise the fixed payment by exactly what you find, the same day.
- Write down the debts the app cannot see, BNPL first, and diarise their payment dates.
Frequently asked questions
Is it better to pay off debt or save first in the UK? Keep a small buffer, then attack the debt. A card at 24.71% costs you far more than any easy access account pays, so every pound above your buffer earns more against the balance than in savings. The exception is that having nothing at all in reserve means the next unexpected bill goes straight back on the card. Our guide to where to keep an emergency fund covers sizing it.
Does paying off debt improve your credit score? Falling balances help, mainly through credit utilisation, and a consistent payment record helps more. Closing an old card can reduce your available credit and your account age, so clearing a balance is not always a reason to close the account. More detail in how to improve your credit score with an app.
What is persistent debt and how do I know if I am in it? It is the FCA’s test in CONC 6.7.27R: over the preceding 18 months you paid less towards the principal than towards interest, fees and charges. Your card firm must check at least monthly and write to you if you meet it. If you have been paying the minimum on a balance over £200 for a year and a half, you almost certainly qualify.
Can a budgeting app see my Klarna or Clearpay balance? Usually not. Open banking gives apps access to payment accounts, and BNPL instalment plans commonly sit outside that, so they will not appear in an app’s balance or net worth totals. Track them separately by payment date, and remember the sector has been FCA-regulated since 15 July 2026, so missed payments now sit inside a formal complaints and forbearance framework.
Should I use a 0% balance transfer card? It can save a large amount of interest, but only if you set a fixed payment that clears the whole balance before the 0% period ends, and stop spending on the old card. Transferring and then reverting to the minimum payment simply moves the debt and buys time you will not use.
Where can I get free debt advice in the UK? StepChange, National Debtline and Citizens Advice all provide it at no cost, and MoneyHelper’s Debt Advice Locator finds services near you. A regulated debt adviser is also the only route into a breathing space moratorium, alongside local authorities.
