Check your credit report free and fix errors
Lenders may use Experian, Equifax or TransUnion. Checking all three — and correcting mistakes — is free and often overdue.
Your credit profile quietly shapes mortgage rates, car finance, phone contracts and even some job checks. In the UK there is no single “the” credit score — Experian, Equifax and TransUnion each keep a file, and lenders choose which to use. Checking your reports, disputing errors and building steady habits costs little more than time. Paid “credit repair” firms are rarely necessary for the basics.
How to see each report without paying for hype
You can access statutory credit reports and there are also free or freemium services that show scores and report summaries. The important part is coverage: make sure you have visibility across the three main agencies over time, not just one app’s score.
When you read a report, look for: wrong addresses, accounts you do not recognise, incorrect missed payments, defaults that should have fallen off, and search footprints you did not authorise. Errors are common after house moves, shared names, or admin mix-ups.
Give yourself a quiet hour the first time — skimming on a phone while commuting is how people miss a stranger’s loan sitting on their file. Note every hard search in the last two years; a cluster of applications can look risky even if each was declined. If you are a victim of fraud, follow the agency’s fraud process and consider a notice of correction where appropriate.
Guarantor loans, joint accounts and old mobile contracts are frequent surprise entries. If you guaranteed someone else’s borrowing, their missed payments can haunt your file until resolved. Deal with that early if a mortgage is on the horizon.

Quick wins that genuinely help
Register to vote at your current address — being on the electoral roll is a classic, legitimate booster because it helps verify identity and stability. Pay every commitment on time, even small ones. Keep credit card utilisation comfortably low (many people aim well under 30% of limits). Avoid a flurry of new applications if you are preparing for a mortgage.
Closing old unused cards can sometimes shorten average account age; think before you cut useful, well-managed limits. Equally, do not open new accounts just to “game” a score.
If you find a mistake, raise a dispute with the agency and the lender. Keep written records. Corrections can improve how lenders see you within weeks once updated.
What not to waste money on
No legitimate service can wipe accurate negative information overnight. Be sceptical of paid repair promises. Focus on accurate data, on-time payments and sensible balances. If debts feel unmanageable, free debt advice beats paid “solutions” that charge fees for things StepChange or National Debtline can discuss for free.
Official consumer credit context sits with bodies such as the FCA; for practical money guidance stay with MoneyHelper and free advice charities.
Worked UK example: an address error costing mortgage options
Maya plans to apply for a mortgage in four months. She checks all three reports and finds an old shared flat still listed as current on one agency, plus a mobile contract default that actually belonged to a previous tenant at that address after a mix-up.
She updates her electoral roll registration, disputes the address and the incorrect default with supporting documents, and pays down a credit card from 45% to 18% utilisation. Six weeks later the corrected report looks cleaner and she avoids applying while the file is still messy — a sequencing choice that can matter as much as the raw score number.
Step-by-step checklist
- Obtain views of Experian, Equifax and TransUnion reports (not just one score app).
- Check names, addresses, employers and account lists for errors.
- Dispute inaccuracies in writing and keep copies.
- Register to vote at your current address.
- Pay down revolving credit so utilisation is comfortably low.
- Avoid unnecessary credit applications before a big lend.
- Set calendar reminders to re-check reports every 6–12 months.
Common mistakes
- Obsessing over one agency’s score number while ignoring report errors.
- Paying a “repair” company for basic disputes you can raise yourself.
- Applying for several new cards at once before a mortgage application.
- Ignoring electoral roll registration after a house move.

Frequently asked questions
What is a good UK credit score?
Each agency uses its own scale, and lenders set their own criteria. Healthy habits matter more than chasing a single magic number.
Does checking my own report hurt my score?
Checking your own file is normally a soft search and does not harm your score the way a lender’s application search can.
How long do defaults stay on a report?
Defaults and many negative items typically remain for six years from the date of the default, even if later paid — verify details on your report and GOV.UK/MoneyHelper guidance.
Do I need all three reports before a mortgage?
You cannot control which agency a lender uses, so reviewing all three reduces the chance of a surprise error on the one they pick.
