UK Credit Score Guide: Ranges, How to Check & Improve Your Score (2026)

By Wealthvieu · Updated

Your credit score affects your ability to get a mortgage, credit card, or loan — and the interest rate you’ll pay. Unlike the US, the UK has three different credit reference agencies with completely different scoring scales.

How Credit Scores Affect Mortgage Rates

Your credit score significantly affects the mortgage interest rate you’ll be offered:

Excellent 4.2% £1,349 £154,700

The difference between excellent and poor credit can cost over £68,700 in extra interest over 25 years.

Myths About UK Credit Scores

Myth Reality
“There’s one credit score” Three agencies, three different scores
“Checking your score lowers it” Soft search — no impact
“Being on the electoral roll doesn’t matter” It matters a lot — lenders use it to verify identity
“Closing old cards helps” Often hurts — reduces credit history length
“Joint finances automatically link you” Only joint accounts and financial associations
“Paying off a default removes it” It stays for 6 years but shows as “satisfied”
“You need to carry a balance” Pay in full — carrying a balance costs interest and doesn’t help
