What Credit Score Do You Need to Buy a House in the UK?

There is no official minimum credit score you need to buy a house in the UK. Mortgage lenders don't share one scoring system between them, and each one looks at your full credit report rather than a single number from a free credit app. That said, a stronger score generally means more lenders willing to say yes, and better rates once they do.

In this guide, we'll explain what the credit reference agencies actually measure, what mortgage lenders look at beyond your score, and the practical steps that can improve your chances before you apply.

Why There’s No “Pass Mark” for a Mortgage

Three credit reference agencies operate in the UK: Experian, Equifax and TransUnion. Each one runs its own scoring model on a different scale, so the same financial history can produce three different numbers. On top of that, most lenders build their own internal credit score using your credit file, your income, and the details on your application, which you never see directly.

That means the score shown on a free banking app or comparison site is a useful guide to your general credit health, but it isn't the figure your mortgage lender will actually use to make a decision.

Credit Score Bands: What Counts as Good, Fair or Poor

Each agency groups scores into bands, from poor through to excellent. These are set by the agencies themselves and used as general guidance only, lenders aren't required to follow them, and many apply their own thresholds behind the scenes.

A “good” or higher score across any of the three generally means access to most mainstream lenders and their more competitive rates. A “fair” score can still lead to an approval, often with a slightly larger deposit or a higher rate. A “poor” score usually points towards a specialist lender.

What Mortgage Lenders Actually Look At

Your credit score is only part of the picture. Lenders also look directly at:

Does It Matter If You’re a First-Time Buyer or Moving Home?

First-time buyers are sometimes judged a little differently, mainly because they often have a thinner credit file, with fewer loans, cards or any mortgage history to show. That isn't automatically a problem. Lenders can draw on utility bills, phone contracts and the conduct of your current account, but a longer, steady record of managing credit tends to help your case. If you have little or no credit history at all, our guide to getting a mortgage with no credit history covers your options in more detail.

Home movers with an existing mortgage usually have more data for a lender to assess, including whether previous mortgage payments were made on time, which carries real weight in a new application.

What If You Have Missed Payments, Defaults, CCJs or an IVA?

Missed payments, defaults, County Court Judgments (CCJs) and Individual Voluntary Arrangements (IVAs) don't automatically rule you out of getting a mortgage, but they do narrow your options to lenders who specialise in adverse credit. These lenders weigh how recent and how severe the issue was, alongside your income and deposit.

If any of this applies to you, our guides to mortgages with adverse credit, CCJs mortgages, mortgages after late payments, and mortgages with an IVA go into more detail on what's realistic for your situation.

How Your Deposit Can Offset a Lower Credit Score

A larger deposit reduces how much you're borrowing against the property's value, known as your loan-to-value, which lowers the lender's risk. That can offset a weaker credit score, sometimes significantly. If your score sits in the fair or poor range, saving a bigger deposit before you apply, even an extra 5 to 10%, can open up lenders who'd otherwise decline you.

Our mortgage deposit guide and average house deposit article can help you plan realistically, and if you're working with little or no deposit at all, see our guide on getting a mortgage with no deposit.

How to Improve Your Credit Score Before You Apply

Most meaningful improvement takes three to six months, though some steps help faster than others:

• Check your credit reports with all three agencies, since lenders can use any of them, and correct any errors you find.
• Register on the electoral roll at your current address if you haven't already.
• Pay down credit card and overdraft balances to below 30% of your limit where possible.
• Catch up any missed or late payments and keep everything on time from now on.
• Avoid applying for new credit, including store cards and phone contracts, in the three to six months before you apply.

Not Sure Where You Stand? Here’s How We Can Help

Whether your score is good enough in practice depends on three things: whether you're buying for the first time or moving home, which tier you currently fall into across the major apps, and whether there are any adverse marks, like missed payments or defaults, on your file.

Tell us where you stand on each of those and one of our advisers will map out exactly how lenders are likely to view your profile, and which ones are worth approaching first. It costs nothing to ask, and there's no obligation to proceed.
