If you have a bad credit rating in the UK, the honest answer has two halves. The damage already recorded — defaults, County Court Judgments, an IVA — sits on your file for six years from the date it happened, and there is no legitimate way to shorten that. What you can change is everything sitting around it: whether you are on the electoral roll, whether the file is even accurate, whether you are still financially linked to an ex-partner, how much of your available credit you are using, and how much clean payment history you have built since.
That second half is not a consolation prize. Lenders weigh recent behaviour heavily, and a file showing two years of faultless payments behind a four-year-old default reads very differently from one showing a four-year-old default and nothing since.
This is a UK guide. UK credit reporting works differently from the American system that dominates search results: different agencies, different score scales, no FICO, no 300–850, and a 30% utilisation rule that is not the rule here. Everything below is specific to a UK file.
The six-year clock, and where it starts
The single most-asked question on this topic is "how long until this goes away", and it has a precise answer. National Debtline, the free advice service run by the charity Money Advice Trust, states that credit accounts in default stay on your credit report for six years from the date of default. Its guide gives matching six-year periods for missed payments, county court judgments, bankruptcy orders, debt relief orders and IVAs.
Two details in that sentence do most of the work.
The clock starts at the default, not at the repayment. A default registered in March 2022 disappears in March 2028 whether you cleared it that year or have never paid a penny. Paying it does not restart the clock either — the entry is simply marked as satisfied, which lenders prefer to see, but the removal date does not move. Anyone offering to remove it sooner is selling you something that does not exist.
There is exactly one erasure available, and it is time-limited. Registry Trust, the not-for-profit that maintains the statutory Register of Judgments, Orders and Fines for the Ministry of Justice, says judgments stay on the public Register for six years unless cancelled, paid within one calendar month, or set aside. Pay a CCJ in full within one calendar month of the judgment date and give the court proof of payment, and the judgment is removed from the Register and the credit reference agencies are told to delete it. This matters to a lot of people: Registry Trust's Q4 2025 statistics summary records 996,261 new consumer judgments in England and Wales in 2025, up 11.8% on 2024.
When each marker leaves a UK credit file
The date the clock starts from is what most people get wrong
- Day 0The clock starts on the date of defaultNot the date you pay. A default recorded in March 2022 comes off in March 2028 regardless of whether the debt was settled in 2022, in 2027, or never.
- Within 1 calendar monthThe only CCJ that can be erasedPay a County Court Judgment in full within one calendar month of the judgment date and give the court proof of payment. Registry Trust removes it from the public Register and notifies the credit reference agencies to remove it from their files. One day late and this option is gone.
- 6 yearsDefaults, missed payments and CCJs drop offNational Debtline gives six years for accounts in default (from the date of default), for missed payments, and for county court judgments — deleted six years from the date the judgment was made, whether or not they have been paid.
- 6 yearsInsolvency markers drop offBankruptcy orders, debt relief orders and administration orders. An IVA is normally deleted six years from the date it was set up, which for a five-year IVA means roughly a year of clean file after it completes.
- After thatInvisible to a search, not to your own bankOnce an entry ages off, a lender searching your file cannot see it. A lender you already hold an account with keeps its own customer records, which is why a bank that wrote off your debt may still decline you.

Work out the drop-off date for every negative entry on your file before you do anything else. If your worst default ages off in eleven months, the sensible plan is to wait and prepare rather than pay a broker to find you a subprime product now.
You do not have "a" credit score
The three UK credit reference agencies (CRAs, not "bureaus") are Experian, Equifax and TransUnion. Each holds a slightly different set of data on you, each scores it on its own scale, and none of those scales is comparable to the others.
The three UK credit reference agencies score you differently
- Good861–1000
- Very good1001–1120
- Excellent1121–1250
- Fair / Low641–860 / 0–640
- Moved from the old 0–999 scale in autumn 2025, so a banking app may still show the old number
- Poor0–438
- Excellentover 811
- Band figures are from Equifax's own guidance page, last updated April 2021
- Intermediate bands widely quoted elsewhere are not published on Equifax's own pages
- Published band boundariesnone
- TransUnion's own FAQ describes Experian as out of 999 and Equifax as out of 700 — both now out of date
- Same person, same month, three unrelated numbers

Now the part that most UK articles get wrong, including the earlier version of this one. No lender approves or declines you on the basis of the number in your Experian app. Lenders build their own internal scorecards, combining the raw data a CRA supplies with your application details and, if you are already a customer, how you have behaved with them. Two lenders looking at an identical file will reach different answers because they are selling to different risk appetites. The consumer score is a rough progress indicator, nothing more.
That is also why the same person gets three different scores: the agencies hold different data. The regulator has been trying to fix that. The FCA published CP26/7 in February 2026, consulting on rules that would oblige lenders to report credit information to designated credit reference agencies so the three do not hold different records on the same person. The consultation closed on 1 May 2026 and the FCA is still considering responses — these are proposals, not rules, so for now you have to check all three yourself.
Step 1: read all three files, and pay nothing for it
You are legally entitled to your statutory credit report from each agency free of charge, and all three also run free consumer-facing products. Check the agency's own website for the current free route rather than clicking the first advert you see, and never enter card details for a "free trial" that converts to a monthly subscription.
Most people are not doing this. The FCA's Financial Lives 2024 survey found that one in three UK adults obtained a credit report or checked their score in the year to May 2024, and only 5% of those who checked paid a fee for it.
Checking your file is free, quick, and worth doing

Reading your own file is a soft search. It is visible only to you and has no effect on how a lender assesses you, no matter how often you do it.
Step 2: register to vote at your current address
This is the fastest, cheapest and most reliable improvement available to a UK credit file, and it is the item most commonly missing from a bad one.
Lenders and CRAs use the electoral register to confirm you are who you say you are and that you live where you say you live. If you are not on it at your current address, applications can fail identity verification before anyone even looks at your repayment history. Register at your local authority through the government's register-to-vote service; it is free and takes a few minutes.
Two edge cases. If you have an anonymous registration for safety reasons you will not appear on the open register, so you will need to prove your address another way; say so on applications rather than leaving it unexplained. And if you have moved, register at the new address — address history is part of what lenders match against.
Step 3: fix errors, and break dead financial associations
Two separate jobs here, and the second is the one nobody mentions.
Errors. If an entry is wrong — a payment marked late that you made on time, an account you never opened, a default recorded at the wrong date — raise a dispute with the CRA showing it. The agency investigates with the lender and the entry is flagged as disputed while that happens. Be persistent: the FCA found that among those who raised a dispute with a credit reference agency, just over a third received a response within one month. The FCA flags that particular result as resting on a small number of survey observations, so treat it as indicative rather than exact, but the direction is clear enough — chase.
If the data is accurate but the context matters, you cannot have it removed, and that is where a Notice of Correction comes in: a short statement you can add to your file explaining, for example, that arrears followed a period in hospital. Lenders that read it will consider it. The trade-off is real: a Notice of Correction usually forces an application out of automated decisioning and into manual review, which is slower and not always in your favour. Use it for a genuine explanation, not for grumbling about a lender.
Financial associations. If you have ever held a joint account, joint mortgage or joint loan with someone, the CRAs create a financial association between your files. From then on their credit behaviour can be pulled into decisions about you. Closing the joint account does not automatically break the link — you have to ask each CRA for a notice of disassociation once no joint products remain open. Separated or divorced readers routinely carry an ex-partner's deteriorating file for years without knowing. If you are still working out how to untangle shared money, our guides on joint versus separate accounts and combining finances with a partner cover the mechanics.
While you are at it, consider requesting your file from CIFAS, the UK fraud prevention service. A protective registration or a fraud marker there can block applications for reasons that never show up on a normal credit report.
Step 4: get every account current, in this order
Payment history is the heaviest single input into how a lender reads you, so arrears come before everything else.
The priority order is not "smallest first" or "highest rate first". It is:
- Anything in arrears but not yet defaulted. Getting an account back to current before it defaults prevents six years of damage. This is the highest-value pound you can spend.
- Priority household arrears — rent, mortgage, council tax, energy. These carry consequences worse than a credit marker, and council tax arrears reach a liability order fast.
- Existing defaults. Paying does not remove them or move the drop-off date, but the entry is marked satisfied, which most lenders prefer, and an unsatisfied CCJ is a specific red flag.
If you cannot cover every minimum, stop and get free advice before you start juggling. National Debtline, StepChange, Citizens Advice and MoneyHelper are all free and regulated; our UK debt guide sets out the formal options and what each does to your file.
Call before you miss, not after. An arrangement agreed in advance is usually the difference between an arrangement-to-pay marker and a default.
Step 5: bring utilisation down to under 25%
Credit utilisation is the share of your available credit you are actually using. The 30% figure you have read everywhere is American. Experian UK's own published guidance is to keep utilisation below 25% to help protect your score, and to pay it back as soon as you can if you need to use more.
Treat that as a rule of thumb rather than a cliff edge. No agency publishes its scorecard weights, and lenders read utilisation as a continuous signal — 26% is not a different world from 24%.
The arithmetic, worked for a UK reader:
| Now | After paying down | After a limit increase | |
|---|---|---|---|
| Total limits | £4,000 | £4,000 | £7,200 |
| Balance | £1,800 | £1,000 | £1,800 |
| Utilisation | 45% | 25% | 25% |
Two routes to the same number, with different costs. Paying £800 off reduces both the ratio and the interest you owe. A limit increase reduces the ratio and nothing else, and it only helps if you do not then spend the extra headroom. Ask an existing lender for the increase rather than opening a new card, and ask first whether it runs a hard search for a limit review — some do.
One timing trick that costs nothing: most issuers report the balance shown on your monthly statement, not the balance after your payment clears. Paying a few days before the statement date rather than on the due date therefore reports a smaller figure. Check with your issuer which date it reports.
If clearing balances is the bottleneck, the credit card payoff calculator shows what a given monthly payment actually does, and snowball versus avalanche settles the order to pay them in.
Step 6: rebuild with one product, used small
Once the file is accurate and the arrears are dealt with, you need new, clean, boring history. That means one product, used lightly, paid in full by direct debit, for a long time.
- Credit-builder cards. Low limits and high headline APRs. The APR is irrelevant if you clear the balance every month and ruinous if you do not — set the direct debit to "full balance" on day one. Our guide to UK credit card types covers which card does which job.
- Credit-builder loans and savings-linked products. You pay in monthly and receive the money at the end. You are buying payment history, and the fee is the price of that history.
- Rent reporting. Several UK schemes report on-time rent payments to one or more CRAs via Open Banking. Coverage varies by agency, so check which CRAs the specific scheme reports to before assuming it helps everywhere.
The discipline that matters more than the product choice: apply for as little as possible while you rebuild. Use soft-search eligibility checkers, which most UK lenders and comparison sites offer, to see your likely acceptance before a real application leaves a hard search on your file. Each CRA sets out in its own report key how long searches remain visible, so read yours rather than trusting a number from an American article.
A 90-day plan for a damaged UK file
- Week 1 — read all three files freeExperian, Equifax and TransUnion. Write down every negative entry and, next to it, the date its six-year clock started.
- Week 1 — register to vote at your current addressFree, fast, and the most common thing missing from a bad file.
- Week 2 — dispute what is wrong, disassociate from who is goneRaise errors with the CRA showing them. Request a notice of disassociation once no joint products remain open with an ex-partner.
- Weeks 2–4 — stop new damageGet anything in arrears but not yet defaulted back to current. Call lenders before you miss a payment, not after. Take free advice if the minimums do not fit.
- Months 2–3 — cut utilisationExperian's published guidance is to stay under 25% of your available credit. Pay before the statement date so the lower balance is what gets reported.
- Month 3 onwards — one rebuild product, nothing elseOne credit-builder card or loan, cleared in full by direct debit. No other applications. Use soft-search eligibility checkers before any real application.

What a repaired file is actually worth
Credit pricing in the UK is spread out enough that the file is worth real money.
Average advertised UK borrowing rates, July 2026
Source: Bank of England — quoted household interest rates, Series IUMODTL, IUMCCTL, IUMBX67, IUMHPTL, month-end 31 July 2026
Two things to take from that chart. First, the £5,000 loan costs nearly double the rate of the £10,000 one, because lenders price small loans as a different product — borrowing more to reach a cheaper tier only saves money if you genuinely do not spend the extra. Second, the gap between the bottom of the ladder and the top is where the value of a clean file sits. The 6.85% at the bottom is an advertised headline rate — the sort of price a clean file competes for, not one a damaged file attracts.
If a mortgage is the goal, the difference shows up in the rate you are offered rather than a simple yes or no. The mortgage calculator guide shows what a rate difference does to a monthly payment, and the first-home savings guide covers deposit and affordability alongside it.
Applying for a mortgage in the next six months
A specific plan, because it is the most common reason people search this topic.
- Stop applying for anything else now. New accounts, new searches and a rising balance in the run-up all read badly.
- Keep balances low across the whole run-up, not just in the month you apply. Lenders look at the pattern.
- Do not close old, well-behaved accounts. A long, clean account is history you cannot buy back.
- Check all three files at least three months out, so a dispute has time to resolve.
- Get your bank statements presentable. Underwriters read months of transactions, and gambling, unarranged overdrafts and short-term loans are risk signals regardless of your score. The debt-to-income calculator shows how much of your income existing commitments take, which is closer to what an affordability test measures than any score is.
When this does not work
Three situations where the advice above is the wrong advice.
When the debt is unaffordable. If your income does not cover essentials plus minimum payments, optimising a score is the wrong problem. Free advice from StepChange, National Debtline or Citizens Advice comes first. A DMP, IVA or DRO will damage your file — not a reason to avoid them if they are the right answer, a reason to decide with an adviser rather than alone.
When the entry is about to age off anyway. If your worst marker drops off in under a year, build clean history and apply after it goes rather than accepting an expensive product now.
When the problem is affordability, not history. Plenty of declines have nothing to do with a score: lenders test whether the payment fits your income and existing commitments. A perfect file will not fix that; a smaller loan or a bigger deposit will. Getting the household budget in order does more here than any credit tactic — start with the step-by-step household budget guide.
Four things you will read that are not true
"There is a credit blacklist." There is not. There is no central list of banned people, and no address is blacklisted. What exists is your file, the previous occupants' files (which do not affect you unless you were financially associated with them), and each lender's own policy.
"A credit repair company can remove accurate entries." Nothing a commercial firm can legally do is something you cannot do yourself for free. Disputes, Notices of Correction and disassociations are all free and all take minutes. If you want help, use a free regulated service — StepChange, National Debtline, Citizens Advice or MoneyHelper — not a firm charging a fee to write the same letters.
"Checking your own score damages it." It does not. Checking your own file is a soft search and is invisible to lenders.
"You need to carry a balance to build credit." You do not. Using a card and clearing it in full every month builds exactly the same payment history and costs nothing in interest. Maximum credit score strategies goes further into the levers that actually move a file.
The honest summary
You cannot make six years pass faster. What you can do, this month, for free: register to vote, read all three files, correct what is wrong, disassociate from an ex-partner, get anything in arrears back to current, and drive utilisation down. Then add one boring rebuild product and leave it alone. That is the whole method, and it is the same method a paid firm would sell you.
