How long does negative information last?

Missed payments, defaults and CCJs stay for six years from the event, whether or not you later pay. Their impact fades over time even before they drop off.

Does checking my own credit hurt my score?

No. Checking your own file is a soft search, invisible to lenders and free at all three bureaus. Only applications create hard searches.

Which credit score do lenders actually use?

None of the ones you see — lenders build internal scores from the underlying data. Focus on the report contents, not the marketing number.

How do I improve my credit score fastest?

Register on the electoral roll, cut utilisation below 30%, and never miss a payment. Visible improvements typically show within 1–3 months.

Should I close old credit cards?

Often it's better to keep them. Old accounts lengthen credit history and unused limits lower utilisation — both help your score. Close cards only if temptation or fees outweigh that.

Expert Tip — Check All Three

Each credit reference agency (Experian, Equifax, TransUnion) holds slightly different data. Some lenders use only one agency. It's worth checking all three to catch any errors. You're also entitled to a free statutory credit report from each agency — see GOV.UK credit file guide ↗.

What Makes Up Your Credit Score?

Payment history (35%): Always paying on time is the single biggest factor
Credit utilisation (30%): Keep credit card balances below 30% of your limit
Length of credit history (15%): Older accounts help
New credit applications (10%): Multiple applications in a short time hurt your score
Credit mix (10%): Having a mix of credit types can help

Frequently Asked Questions

Does checking my credit score affect it?

No. Checking your own score is a 'soft search' and has no impact on your credit rating. Only 'hard searches' (like a full credit application) are visible to lenders and affect your score.

What credit score do I need for a mortgage?

There's no fixed minimum — each lender has their own criteria. For the best rates you'll typically want 700+ (Experian), 660+ (Equifax) or 600+ (TransUnion). See our bad credit mortgage guide if your score is lower.

How long does it take to improve a credit score?

Most people see meaningful improvement in 3–6 months with consistent positive behaviour. Negative marks (late payments, defaults) reduce in impact over time and disappear entirely after 6 years.

Key takeaways

Pay cards before the statement date (not due date) to shrink reported balances
Check all three bureaus free — each holds different data and different errors
Electoral roll + utilisation under 30% + zero missed payments = most of the score
Keep old cards open — account age and unused limits both help

Read This Before You Apply

Old joint accounts haunt credit files: a joint account or mortgage links your file to another person's record indefinitely unless you formally disassociate. After any separation, disassociation should be on the checklist next to the address change.

Credit scoring rewards boring consistency above everything: long-held accounts, low utilisation, zero missed payments. Quick wins exist: electoral-roll registration shows in the next cycle, and paying before your statement date (not the due date) reports lower utilisation immediately.
