Credit reports and credit scores

Your credit report is a record of your borrowing and repayment history, held by credit reference agencies. A credit score is a number the agencies, or a lender, calculate from it. There is no single national score. Each agency has its own scale, and lenders use their own scorecards, so a good score with one agency does not guarantee approval.

What is on your credit report

  • Credit cards, loans, mortgages, overdrafts and some buy now pay later accounts, and whether payments were on time.
  • Defaults, county court judgments, IVAs, debt relief orders and bankruptcy.
  • Searches by lenders when you apply for credit.
  • Your address history and whether you are on the electoral roll.
  • Financial associations with people you share accounts with.

Talk to a free adviser first

An adviser can look at your whole budget, deal with creditors for you and explain which option suits you. Get free debt advice.

How long things stay

EntryUsually stays for
Missed paymentsSix years
DefaultsSix years from the default date
CCJsSix years, unless paid in full within one month
IVAs, DROs and bankruptcySix years from the start date
Hard searchesAbout 12 months

Time periods are the standard industry rules. Paying a default does not remove it, but marks it as settled.

Check your report

You can see your statutory credit report from each of the three agencies for free. Check all three, because each may hold different information. Look for accounts you do not recognise, wrong balances, missed payments that were not missed and people you should not be linked to.

Correcting mistakes

  • Contact the lender that supplied the wrong information and ask it to correct it.
  • You can also ask the credit reference agency to investigate, and add a short notice of correction to your file explaining your side.
  • If it is not resolved, complain to the Financial Ombudsman Service or the Information Commissioner’s Office.

How to improve your record

  • Pay at least the minimum on time, using direct debits.
  • Register on the electoral roll at your current address.
  • Keep balances well below your limits.
  • Avoid making many credit applications in a short time, and use eligibility checkers that do not leave a hard search.
  • Close or freeze joint accounts and ask for a notice of disassociation after a split. See joint debts.
  • Be patient. Negative entries fade as they age, and recent good behaviour counts for more.

Beware of credit repair claims

Companies that charge to "wipe" accurate negative entries cannot do it legally. Everything they can do, such as checking your file and disputing errors, you can do yourself for free. If you are struggling with debts, speak to a free adviser instead.

Frequently asked questions

What is a good credit score?

It depends on the agency and the lender. Focus on a clean, up-to-date record rather than one number.

Does checking my own credit report lower my score?

No. A check of your own file is a soft search that lenders cannot see.

Does paying off a CCJ or default remove it?

Paying a default marks it as settled but does not remove it. A CCJ paid in full within one month can be removed, otherwise it stays for six years marked as satisfied.

Can I get credit with a poor score?

Often, but at a higher cost. Be wary of high-cost lenders. A credit union or credit-builder product may be a better route.

Does an IVA ruin my credit?

It has a serious effect for the six years it stays on your file, but a good record afterwards helps you recover. See our IVA guide.
