- Pay cards before the statement date (not due date) to shrink reported balances
- Keep old cards open — closing your oldest card can hurt
- Electoral roll + utilisation under 30% + zero missed payments = most of the score
- Check all three bureaus free — each holds different data and different errors
Insider Notes
Check all three bureaus, not one: Experian, Equifax and TransUnion hold overlapping but distinct records, and an error on any one can sink an application with lenders who use it. All three offer free access — use it annually.
The algorithm's favourite customer is predictable: 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.
Financial associations outlive relationships: 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.
IVA and Your Credit Score
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
No. Checking your own file is a soft search, always free and harmless. Only applications create hard searches.
Three moves matter most: electoral roll, utilisation under 25–30%, and perfect payment history. Visible improvements typically show within 1–3 months.
Usually not. 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.
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.
Not Experian's, Equifax's or TransUnion's headline number — lenders build internal scores from the underlying data. Focus on the report contents, not the marketing number.
