What Credit Score Do I Need to Buy a House? 

One of the questions first-time buyers ask most is whether they need a perfect credit score to get a mortgage. The short answer is no – but your credit history acts as your financial CV, and a clean one is your best asset. 

There’s no universal minimum score 

It’s a common misconception that you need a specific number (like 900+) to buy a home. UK lenders use different credit reference agencies: Experian, Equifax, and TransUnion – and each has a different scale. 

Lenders don’t just see the number; they see the data. They use Open Banking to verify your real-time spending, looking for what’s known as conduct. They want to see you staying within your overdraft limits and avoiding excessive Buy Now Pay Later (BNPL) use in the six months before you apply. 

Why a better score saves you money 

While a fair score might get you a mortgage, a good or excellent score unlocks the best deals. 

A high score can be the difference between a 3.5% and a 5% interest rate (as of early 2026), potentially saving you hundreds of pounds every month. If your credit is excellent, some lenders offering professional or helping hand schemes may allow you to borrow up to 5.5x or 6x your income – and in very rare professional cases, up to 7x.

Quick wins to boost your profile 

If you’re planning to buy in the next 6-12 months, take these steps now. 

Make sure you’re registered on the electoral roll at your current address. This is the fastest way for automated systems to verify your identity. Report any errors on your credit file – even a small mistake in your address history can trigger a referral or rejection. 

Try to keep your credit card balances below 25% of your limit. This shows lenders you aren’t relying on credit to live. And avoid taking out new credit – no new car loans or store cards in the six months before your mortgage application.

Beyond the score: affordability 

Your credit score is just one pillar. Lenders also look at your deposit (a 10% or 15% deposit can often offset a slightly lower score), your debt-to-income ratio (how much of your monthly pay goes toward existing debts), and your employment stability (lenders typically prefer seeing at least 3-6 months in your current role).
