Mortgage with a Low Credit Score UK: Options & Tips

What credit score do you need for a mortgage?

There's no single 'minimum credit score' for a UK mortgage because each credit reference agency (Experian, Equifax, TransUnion) uses a different scoring system, and each lender has its own assessment criteria.

As a rough guide: on Experian (0–999), scores below 721 are considered 'poor'; on Equifax (0–1000), below 380 is 'poor'; on TransUnion (0–710), below 566 is 'poor'. However, lenders look at the underlying data, not just the headline score.

Why your score is low

Common reasons for a low credit score include:

• Missed or late payments on credit agreements, loans, or bills
• High credit utilisation — using more than 30% of your available credit
• CCJs, defaults, or insolvency on your credit file
• Too many credit applications in a short period
• No credit history — surprisingly, having no credit can be as problematic as bad credit
• Errors on your credit file — incorrect addresses, wrong account statuses

Quick ways to improve your credit score

Some improvements can make a difference within weeks:

• Register on the electoral roll at your current address — this alone can add 50+ points
• Correct any errors on your credit reports
• Pay down credit card balances to below 25% of their limits
• Set up direct debits for all bills to avoid missed payments
• Avoid new credit applications in the 3–6 months before your mortgage application
• Ask to be removed as a financial associate of someone with poor credit

Mortgage options with a low score

If your score is low but you don't have serious adverse credit (no CCJs, defaults, or insolvency), many mainstream lenders will still consider you, especially with a larger deposit. A deposit of 15%+ opens significantly more doors than 5%.

If your low score is caused by adverse credit events, specialist lenders like Pepper Money, Kensington, and Bluestone cater specifically to this market. Rates will be higher but the mortgage is achievable.

The role of a mortgage broker

A broker can look beyond your headline credit score and assess your full financial picture. They know which lenders are more flexible on credit scores and can often find deals you wouldn't find on your own.

Crucially, a good broker will do an initial 'soft search' that doesn't affect your credit score, giving you an idea of your options before committing to a full application.

Whether your score needs a quick fix or you need specialist lending, the right broker makes all the difference.
