- Pay cards before the statement date (not due date) to shrink reported balances
- Keep old cards open — account age and unused limits both help
- Check all three bureaus free — each holds different data and different errors
- Electoral roll + utilisation under 30% + zero missed payments = most of the score
Insider Notes
Credit scoring rewards boring consistency above everything: old accounts, small balances, perfect history. Quick wins exist: electoral-roll registration shows within weeks, and paying before your statement date (not the due date) reports lower utilisation immediately.
Old joint accounts haunt credit files: a joint account or mortgage links your file to another person's behaviour until you file a notice of disassociation. After any separation, disassociation should be on the checklist next to the address change.
Your three credit files disagree more than you'd think: Experian, Equifax and TransUnion hold different data from different lenders, and each error is invisible until the wrong lender checks the wrong file. Statutory reports are free from all three.
Credit Score for Car Finance
Your credit score is used by lenders to assess how likely you are to repay what you borrow. In the UK, credit scores are calculated by three main credit reference agencies (CRAs): Experian, Equifax, and TransUnion.
How UK Credit Scores Work
Each CRA uses a slightly different scoring scale:
| Agency | Score Range | "Good" Score | Check Free At |
|---|---|---|---|
| Experian | 0–999 | 881+ | experian.co.uk ↗ |
| Equifax | 0–700 | 420+ | ClearScore ↗ |
| TransUnion | 0–710 | 604+ | Credit Karma ↗ |
Key Factors Affecting Your Score
- Payment history — paying on time is the biggest factor
- Credit utilisation — keep below 30% of your credit limit
- Length of credit history — older accounts help
- Credit mix — a mix of credit types (card, loan, mortgage)
- New applications — too many hard searches in a short period hurt your score
- Electoral roll — being registered improves your score
Practical Steps to Improve Your Score
- Register on the electoral roll
- Pay all bills on time — set up direct debits
- Keep credit card balances below 30% of the limit
- Don't close old accounts unless necessary
- Check your credit report for errors and dispute any mistakes
- Space out credit applications by at least 3–6 months

Frequently Asked Questions
Not Experian's, Equifax's or TransUnion's headline number — lenders build internal scores from the underlying data. Treat your visible score as a rough health gauge only.
No. Checking your own file is a soft search, always free and harmless. Only applications create hard searches.
Register on the electoral roll, cut utilisation below 30%, and never miss a payment. Visible improvements typically show within one to three statement cycles.
Missed payments, defaults and CCJs stay for 6 years, whether or not you later pay. Their impact fades over time even before they drop off.
Usually not. Old accounts lengthen credit history and unused limits lower utilisation — both help your score. Close cards only if temptation or fees outweigh that.
