UK Credit Score Guide 2026: Experian, Equifax and TransUnion Explained
Updated April 2026 · 10 min read
Understanding UK Credit Scores: Three Agencies, Three Different Numbers
The UK has three credit reference agencies — Experian, Equifax, and TransUnion — each with their own scoring system. A score of 700 means something completely different on each scale. Lenders may check one, two, or all three agencies, so your score with each one matters. The good news: the factors that improve your score are the same across all three.
Check your score for free: ClearScore shows your Equifax score, Credit Karma shows TransUnion, and MSE Credit Club shows Experian. Monitor all three monthly to catch errors and track improvement. Use our credit utilization calculator to optimize one of the biggest score factors.
The Fastest Ways to Improve Your UK Credit Score
Register on the electoral roll (immediate and significant impact). Keep credit card utilization below 25 percent. Never miss a payment — set up direct debits for at least the minimum on all credit accounts. Space credit applications at least 3 months apart. If you have thin credit history, a credit-builder card (used for small purchases and paid in full) builds your file quickly.
Avoid common mistakes: closing old credit cards (reduces your total available credit and average account age), making multiple credit applications in a short period (each hard search is visible), and only paying minimums on credit cards (signals financial stress).

Frequently Asked Questions
What is a good credit score in the UK?
Experian: 881 to 960 is good, 961 to 999 is excellent (out of 999). Equifax: 531 to 670 is good, 671 to 1000 is excellent. TransUnion: 604 to 627 is good, 628 to 710 is excellent. Each agency uses different scales so the numbers are not comparable.
How can I check my credit score for free?
ClearScore (uses Equifax data): free monthly updates. Credit Karma (uses TransUnion): free weekly updates. MSE Credit Club (uses Experian): free monthly Experian score. All three are genuinely free with no hidden costs.
Does checking my credit score lower it?
No. Checking your own score through ClearScore, Credit Karma, or similar services is a soft search that does not affect your score. Only credit applications (hard searches) can temporarily lower your score.
How long do negative marks stay on my credit report?
Six years from the date of the event. This includes missed payments, defaults, CCJs, and bankruptcy. After 6 years, they are automatically removed. There is nothing you can do to remove accurate negative information before the 6-year period ends.
Does being on the electoral roll really help?
Yes. Being registered on the electoral roll at your current address is one of the single biggest factors for UK credit scores. It verifies your identity and address. If you are not registered, this should be your first action — it is free and takes 5 minutes at gov.uk.
