Equifax Credit Score — UK Guide: This guide covers what you need to know, how credit scores work in the UK, and practical steps you can take today. Check your score free at Experian, Credit Karma (TransUnion), or CheckMyFile.
- Check all three bureaus free — one clean file doesn't mean three
- Pay cards before the statement date (not due date) to shrink reported balances
- Electoral roll + utilisation under 30% + zero missed payments = most of the score
- Keep old cards open — closing your oldest card can hurt
What Actually Moves the Needle
Old joint accounts haunt credit files: a joint account or mortgage links your file to another person's record until you file a notice of disassociation. After any separation, disassociation should be on the checklist next to the address change.
The algorithm's favourite customer is predictable: old accounts, small balances, perfect history. Quick wins exist: electoral-roll registration shows within weeks, and utilisation resets every statement — pay before the statement date, not the due date, to report a lower figure.
Equifax Credit Score — UK Guide
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
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.
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 one to three statement cycles.
None of the ones you see — lenders build internal scores from the underlying data. Treat your visible score as a rough health gauge only.
Missed payments, defaults and CCJs stay for 6 years, whether or not you later pay. Recent behaviour weighs far more than old problems.
