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.

How do I improve my credit score fastest?

Three moves matter most: electoral roll, utilisation under 25–30%, and perfect payment history. 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 — closing your oldest card can actually drop your score. Close cards only if temptation or fees outweigh that.

Which credit score do lenders actually use?

None of the ones you see — lenders build internal scores from the underlying data. Treat your visible score as a rough health gauge only.

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 report lower utilisation instantly
Electoral roll + utilisation under 30% + zero missed payments = the core formula
Keep old cards open — account age and unused limits both help
Check all three bureaus free — each holds different data and different errors

Beyond the Basics

Check all three bureaus, not one: Experian, Equifax and TransUnion hold different data from different lenders, and each error is invisible until the wrong lender checks the wrong file. All three offer free access — use it annually.

Financial associations outlive relationships: a joint account or mortgage links your file to another person's record indefinitely unless you formally disassociate. An ex-partner's missed payments can quietly tax your applications for years.

Credit scoring rewards boring consistency above everything: long-held accounts, low utilisation, zero missed payments. There are no shortcuts, but there are accelerants: electoral-roll registration shows in the next cycle, and utilisation resets every statement — pay before the statement date, not the due date, to report a lower figure.
