How to Improve Your Credit Score Before Applying for a Mortgage

Your credit score is one of the first things a mortgage lender will assess when you apply. A stronger score can open the door to a wider choice of lenders and more competitive rates, while a lower score may limit your options or mean higher borrowing costs. This guide explains what your credit score means in the context of a mortgage application, what lenders look for, and the practical steps you can take to improve your position before you apply.

Your home may be repossessed if you do not keep up repayments on a mortgage or any other debt secured on it.

What Is a Credit Score and Why Does It Matter for a Mortgage?

A credit score is a numerical summary of your borrowing and repayment history, calculated by a credit reference agency. In the UK, the three main agencies are Experian, Equifax and TransUnion. Each uses its own scoring model, so your score will differ between them.

Mortgage lenders use credit data to assess how reliably you have managed debt in the past. They do not all use the same agency, and many run their own internal scoring alongside the agency data. This means there is no single universal score that determines whether you will be approved. A score that one lender considers acceptable may be viewed differently by another.

What matters more than any headline number is the detail behind it: whether you have missed payments, how much outstanding debt you carry, whether you have any county court judgments or defaults, and how stable your financial behaviour appears over the past six years.

Understanding Credit Score Ranges

Each agency uses a different scale, which can make it difficult to compare scores directly. As a general indication:

•       Experian scores range from 0 to 999. A score below 721 is typically considered poor, 721 to 880 is fair, 881 to 960 is good, and 961 to 999 is excellent.

•       Equifax scores range from 0 to 700. Below 380 is generally considered poor, 380 to 419 is fair, 420 to 465 is good, and 466 to 700 is excellent.

•       TransUnion scores range from 0 to 710. Below 566 is typically considered poor, 566 to 603 is fair, 604 to 627 is good, and 628 to 710 is excellent.

These bands are useful as a rough guide, but they do not determine mortgage eligibility on their own. Lenders weigh your full credit file, income, deposit and the property itself when making a decision. If you are unsure where you stand, downloading your credit report is a sensible first step.

Practical Steps to Improve Your Credit Score

Improving your credit score takes time, so it is worth starting well before you plan to apply for a mortgage. The steps below address the factors lenders focus on most.

•       Register on the electoral roll. This is one of the simplest ways to strengthen your credit file. Lenders use the electoral roll to verify your identity and confirm your address. If you are not registered, some lenders may decline your application on that basis alone.

•       Pay all bills and credit commitments on time. Late or missed payments are among the most damaging entries on a credit report. Set up direct debits to ensure regular payments on credit cards, loans, mobile contracts and utility bills.

•       Reduce outstanding debt. Paying down existing balances, particularly on credit cards and overdrafts, shows lenders you are managing your finances responsibly. It also improves your debt-to-income ratio, which affects mortgage affordability assessments.

•       Keep credit utilisation low. Try to use no more than 25 to 30 per cent of your available credit limit across all cards. High utilisation suggests reliance on credit, which lenders view as a risk.

•       Avoid new credit applications in the run-up to your mortgage. Each application places a hard search on your credit file. Several hard searches in a short period can lower your score and may signal financial stress to a lender. Aim to avoid applying for new credit for at least six to twelve months before your mortgage application.

•       Close unused credit accounts. Open but inactive credit cards or store accounts add to your total available credit. Some lenders factor this in when assessing affordability, even if the accounts carry no balance.

•       Check your credit report for errors. Mistakes on your file, such as incorrect addresses, debts that have been repaid but still show as outstanding, or accounts that do not belong to you, can drag your score down. Report inaccuracies to the relevant agency and ask for them to be corrected.

•       Resolve disputes before they escalate. Even minor debts, such as unpaid parking fines or disputed utility bills, can result in a county court judgment if left unresolved. A CCJ remains on your credit file for six years and can seriously affect your mortgage prospects.

What Lenders Look At Beyond Your Credit Score

A strong credit score is important, but it is only one part of a lender’s assessment. Mortgage lending criteria vary between lenders, and the following factors all play a role in the decision.

•       Deposit size. A larger deposit reduces the loan-to-value ratio, which lowers the lender’s risk. Borrowers with a higher deposit may access more competitive rates, even if their credit history is not perfect. Our mortgage deposits guide explains how much you may need to save.

•       Income and affordability. Lenders carry out detailed mortgage affordability assessments to check that you can comfortably meet your repayments alongside your other financial commitments. Income type matters too. Self-employed applicants, contractors and those with overseas income may face additional documentation requirements.

•       Employment status. Stable employment with a consistent income is generally viewed favourably. If you are self-employed or work on contracts, lenders typically ask for two to three years of accounts or tax returns.

•       Property type. Non-standard construction properties, flats above commercial premises or properties with short leases can be harder to mortgage. This is because of potential resale risk if the lender needed to repossess.

•       Age. Most lenders set minimum and maximum age limits, either at the point of application or at the end of the mortgage term.

How Mortgage Credit Checks Work

When you apply for a mortgage, the lender will run a credit check. There are two types. A soft search gives the lender a summary view of your credit profile without leaving a visible mark on your file. A hard search is a full review of your credit history and does leave a footprint that other lenders can see. Our mortgage credit checks guide covers how each type works and when they are used during the application process.

Multiple hard searches within a short period can lower your score, which is one reason why working with a broker can be valuable. Rather than applying to several lenders directly, a broker can identify the most suitable lender for your profile before any hard search is carried out.

What If Your Credit Score Is Low?

A low credit score does not automatically mean your mortgage application will be declined. Some lenders specialise in cases involving adverse credit, including applicants with defaults, CCJs, individual voluntary arrangements or a history of missed payments. These lenders may accept applications that high street banks would not, though the terms will often reflect the additional risk, typically through higher interest rates or larger deposit requirements.

If your credit history includes more serious issues, our bad credit mortgage guide explains the options available and how a broker can help match your circumstances to the right lender.

For first-time buyers building a credit history from scratch, a thin credit file can be just as much of a challenge as a poor one. Opening a credit card, using it for small regular purchases and repaying it in full each month is one way to build a track record. Our first-time buyer mortgage guide covers the full range of considerations when buying your first home.

Timing Your Application

Credit scores do not improve overnight. If you know you want to apply for a mortgage in the coming months, it is worth reviewing your credit report as early as possible so you have time to address any issues. As a general rule, allow at least three to six months to make meaningful improvements, though some changes, such as registering on the electoral roll, can take effect within weeks.

If you are remortgaging, the same principles apply. Lenders will run a fresh credit check, and your current score will influence the rates available to you. Our remortgaging guide explains the process and what to prepare.

Before submitting a formal mortgage application, consider getting your credit report reviewed by a broker. Mortgage One can assess your report, highlight any areas of concern and advise on the right time to apply.

FAQs

1. Is there a minimum credit score needed to get a mortgage?

There is no fixed minimum score that applies across all lenders. Each lender uses its own criteria and may use a different credit reference agency. A score that one lender considers too low may be acceptable to another, particularly among specialist lenders.

2. Will checking my own credit report lower my score?

No. Checking your own credit report is recorded as a soft search and has no effect on your credit score. You can check it as often as you like without any impact.

3. How long does it take to improve a credit score?

Some changes can take effect quickly, such as registering on the electoral roll or correcting an error on your file. Others, like building a consistent payment history or reducing debt levels, take several months. Allow at least three to six months before applying if you need to make significant improvements.

4. Does a mortgage broker check my credit score?

A broker may ask for a copy of your credit report or request permission to obtain one. This helps the broker assess your profile and identify suitable lenders, reducing the number of hard searches on your file.

5. Can I get a mortgage with a CCJ on my credit file?

It may be possible, depending on the size of the CCJ, when it was registered and whether it has been satisfied. Some specialist lenders will consider applications with CCJs, particularly if the judgment is older or for a small amount. A larger deposit is usually required.

6. Why do Experian, Equifax and TransUnion give me different scores?

Each agency uses its own scoring model, data sources and scale. A lender may use one, two or all three agencies, plus their own internal scoring. This is why your score can vary and why no single number defines your mortgage eligibility.

7. Should I close old credit cards before applying for a mortgage?

It depends on your circumstances. Closing unused accounts reduces your total available credit, which some lenders view positively. However, closing a long-standing account can shorten your credit history, which may have the opposite effect. A broker can advise on whether closing a particular account would help or hinder your application.

8. How can Mortgage One help with my credit score and mortgage application?

Mortgage One can review your credit report, identify any issues that may affect your application and recommend steps to improve your position. When you are ready to apply, a broker can match your profile to lenders whose criteria suit your circumstances, reducing the risk of unnecessary hard searches and declined applications.
