Overview of the UK credit system

Each country has its own credit system so if you’re a new arrival or expat you’ll want to get to grips with how credit scores work in the UK.

Having a local credit score in the UK is important as it’s one way your creditworthiness is established when you take out credit, or take on a contract like a rental agreement on a home, or a new phone or broadband agreement. Unfortunately when you move countries you might find you have to build your local credit history from scratch.

We’ll cover how to check a UK credit score in this guide, as well as how you can improve your credit score to make it easier to manage your UK finances.

This guide is for information only. If you need support with understanding your UK credit score, get professional financial advice.

Understanding credit scores in the UK

There are three major credit score companies in the UK. They all operate a little differently, but similar factors are taken into account when they run a credit score check.

Credit score agencies in the UK get their information from the following:

• The Electoral Roll – the register of voters, which shows confirmed addresses for individuals
• Public records covering court judgments, bankruptcies and other legal decisions about your financial affairs
• Existing account information including your bank account and other borrowing, showing account use and repayment patterns
• Home repossessions – details can be provided by your mortgage lender if you have have a UK home repossessed
• Financial associations including people you’ve got a joint account with or where you’ve made joining applications for credit
• Address associations – covering any other UK addresses you’ve lived at
• Previous searches showing which other companies have checked your score in the past year

Each credit bureau then assigns a score to you, which is checked and updated regularly as additional information is passed to the agency. Different bureaus use their own scoring mechanisms and have their own ranges which are considered Exceptional – Poor.

To give an example, here’s an outline of the Experian credit score ranges:

It’s helpful to know that different credit agencies in the UK have very different scoring ranges, which means that their average scores vary a lot:

• TransUnion UK average is 573
• Experian UK average is 797
• Equifax UK average is 585

Before you start thinking about your UK credit score it’s helpful to get reports from several agencies so you can see where you stand – bearing in mind they score on different scales and may have slightly varied metrics.

Credit bureaus and credit reports in the UK

There are three major credit score bureaus in the UK:

• Experian UK
• Equifax UK
• TransUnion UK

Each has a different scoring method, and different score range. That means that what counts as a good score with one bureau may not be the same for the next. All that really matters is that the agency checking your score – like a bank or a credit card company – agrees your score is adequate for the services they’re offering.

Why credit scores matter for expats in the UK

UK credit scores can be used for the following:

• Mortgage applications and home buying requirements
• Credit card approvals and interest rates
• Personal loan access and terms
• Rental applications and security deposits
• Insurance premium calculations
• Employment background checks (where applicable)
• Utility deposits and service connections

If you don’t have a good UK credit score you may find your opportunities for getting credit are limited, and interest rates are higher than you’d like when your applications are approved.

What affects your credit score?

Experian states that the factors which impact your UK credit score negatively can include:

• Having little or no credit history – important for expat new arrivals in the UK
• Opening new bank accounts frequently or applying for many credit cards or other loan products all at once
• Running close to your credit limits when spending on a credit card – or missing repayments entirely
• Borrowing more than you can repay – which can result in legal judgements against your name which damage your score significantly

There are also some key factors that don’t affect credit scores including the people you live with or who used to live in your home address, checking your own credit score, or credit history from over six years ago.

Starting with no credit history as an expat

When you first move to the UK you will often find you have no credit history that’s visible to UK credit agencies. While some global banks may be able to check your overseas credit scores this isn’t common. That means you’ll need to build your credit score as quickly as possible to be able to access financial services more conveniently and cheaply in the UK.

How to build credit as an expat in the UK

There are steps you can take to ensure your UK credit score improves, which can mean your future loans and credit cost you less. Here are some ways to build credit as an expat in the UK:

• Register to vote – make sure your name is on the Electoral Roll as this is used to check your identity for credit scoring
• Make regular payments – such as direct debits which show you can manage your money effectively
• Do not borrow too much, and repay credit cards regularly – avoid missing repayments or running up too much debt
• Don’t change accounts too often – including credit cards and bank accounts as frequent applications can look suspicious to credit scoring agencies
• Check and correct errors in your score – check your credit score often and ask to see your credit file. If there are errors in the file you can ask the agency to correct them which can improve your score

Timelines for building credit in the UK as an expat

There’s no single timeline to build your credit score as it will all depend on your individual circumstance. However, here’s an overview of some common actions you might take to improve your UK credit score, and the timings which may work for many expats:

Managing finances in multiple currencies? Check out Wise to make money management easier. Getting to grips with your finances in a new country can be tricky – but using Wise can make it easier to keep on top of your money in different currencies.

Types of credit and their impact

There are some different types of credit which may influence your credit score in the UK in different ways:

Using credit scores for major purchases

Credit scores in the UK are used when you apply for financing of different types – here are some common occasions when your credit score may be important in dictating your approval rates of the credit interest rates you get:

Expats in the UK may find that large or regular payments such as a mortgage or car loan involve sending money from abroad to be received in the UK to cover your repayments. In this case, keep your costs low with international transfers from Wise. You get the mid-market rate with low fees – and there are progressive discounts on the costs when you send higher amounts, with a dedicated support team to help you through every step of the transfer.

Credit score monitoring and improvement

The UK has three major credit agencies which each calculate your score differently. Legally, you are entitled to a free credit report from each which you can get online.

It’s a good idea to check your score and ask for your credit file from each on a regular basis until your credit score in the UK is stable and established. There’s no impact on your score when you request a report from a credit agency – and spotting errors or omissions in your report can help you improve your score in the end.

Credit for different expat situations

It’s common to require credit from time to time, but the reasons and types of credit needed by expats might vary a lot depending on your situation. For example:

• International students may want to apply for a student credit card, which will require a credit check or guarantor in many cases
• Temporary workers may need a credit check to access housing or get a phone for use in the UK
• Permanent residents may be concerned with long-term credit building to get cheaper access to long term products like mortgages
• Digital nomads may need to maintain credit across borders by building a history in the UK whilst also managing their credit history in their home country

While you’re thinking about managing your expat finances in the UK, why not take a look at Wise for low cost currency conversion, easy international transfers, secure card spending and no ongoing account fees.

Common credit mistakes expats make in the UK

Let’s round out with a few common credit mistakes expats make in the UK so you can avoid the pitfalls:

• Failing to appreciate the need for a good credit score – even if you don’t want a loan you may need a UK credit score to secure housing or get a phone
• Not registering your address – get on the Electoral Roll if you can, to ensure this factors into your credit score
• Opening many accounts and cards all at once – applying for several bank accounts and credit cards can reduce your credit score as it may look irresponsible
• Putting too much on credit – moving country is costly, but maxing your cards can mean damaging your long term credit score
