What’s a credit score?

It’s a figure created by a Credit Reference Agency (CRA) that reflects your financial history.

With a better, higher credit score, you’re seen as financially reliable and less risky to lenders. Therefore, you’re more likely to be accepted when you apply for credit – be it a car loan, mortgage, credit card, overdraft or new mobile phone or utility company contract.

A good credit score could also mean you’ll have access to secure the best deals and interest rates on the market too.

You don’t have one universal credit score. Instead, credit reference agencies score you using their own specific criteria as they build up your credit report.

So, your credit score can be different in each credit reference agency, depending on what information they hold in your credit file.

In the UK there are three main credit reference agencies – Experian, Equifax and TransUnion.

These independent organisations gather your personal and financial information and credit history from creditors and lenders. This will include any county court judgements (CCJs), bankruptcies or insolvencies plus past credit agreements and repayment history as well as current credit products and how much you owe.

Lenders - such as banks and building societies and retailers – go to at least one of these three agencies when you apply for credit to examine your credit report.

They do this to get a clear picture of your financial and credit history. The information helps them judge how likely you will be to pay back the amount loaned and whether or not to approve your application.

What is a bad credit score?

Your credit score is a three-digit number calculated by a credit reference agency.

It’s a good guide as to how much of a risk you may be considered by lenders.

The higher your score, the better your credit report and so the more attractive you’ll be to lend to, because you’re seen as financially reliable.

A low, or poor, credit score will mean that your credit report will contain information that will be considered a red flag to lenders – and so you may find your applications for credit are limited or declined.

Confusingly, each credit reference agency (CRA) uses a different numerical scale to score you.

For example Experian provides a score from 0-999 and considers a 'good' score to be between 881-960 and a ‘poor' score between 561-720.

Equifax score levels run from 0-1,000. They rate a score of 0-438 as ‘poor’ and 531 to 670 as ‘good’.

TransUnion’s credit score only goes up to 710. A ‘poor’ score is 551-565 and a ‘good’ score 604-627.

How do I check my credit score?

It’s a good idea to check your credit score regularly, especially if you’re planning on applying for credit. It can give you an idea of how likely you are to be approved.

Checking your credit score – no matter how many times – won’t affect your score.

If your credit score is poor you might want to take steps to improve it before you apply for credit.

Too many applications can adversely affect your score.

As well as knowing your credit score, getting hold of your credit report from one or all of the CRAs is really useful too.

You can check for factual errors, challenge them (either with the finance provider or CRA) and get them corrected. This can boost your score.

And you may even spot signs of identity theft early – where a fraudster has taken out a loan in your name, for example – if you review your report regularly.

You can request a free statutory copy of your credit report from all UK credit reference agencies.

How to improve your credit score.

There’s plenty you can do to boost your score.

  1. Get on the electoral register

    If you’re not already on it, get on the electoral register. It helps verify your identity and address to lenders, preventing fraud.

  2. Keep up payments

    Keep up with repayments - and pay them on time. Missed or late payments go on your record and indicate to lenders that you may struggle to manage financially.

  3. Watch your balance

    Try to pay your credit card balance in full each month. If that’s not feasible, aim to keep your balance at less than 30% of your credit limit. Lenders look at your ‘credit utilisation’ - the percentage you use of your credit limit. The lower the percentage you use, the more positively lenders see it.

  4. Build your credit history

    If you’ve never taken out any form of credit before, it can count against your credit score.

With no credit history, lenders can’t judge whether or not you’re a good bet to lend to. So, you may be refused credit, even when you can comfortably afford to repay.

You could take out a ‘credit builder’ card to build up a personal credit history. This type of card tends to have very high interest rates, though – so be sure you pay back the full amount you borrow every month or you’ll get stung.

The Experian Boost tool from Experian can help people with no credit history.

It’s a tool that connects to your current account and scans it for payments and subscriptions that can boost your credit score.

Regular payments into investments and savings, such as ISA and monthly saver accounts, Council Tax and even digital subscriptions such as Netflix and Spotify can all indicate that you manage your money well and so can go towards boosting your credit score.

Cut financial associations

If you have a financial association – such as a joint mortgage or loan – with someone who has a bad credit history, it will affect your credit file and score too. If you no longer share finances with someone, you can let each of the CRAs know and ask for them to be removed from your credit report.

Why is it important to have a good credit score?

A higher score usually makes you more attractive to a lender and therefore more likely to be approved for credit when you need it.

What’s more, the better your credit score, the more access you should get to a wider range of financial products – with more generous limits and the best possible interest rates.

How long does it take to improve your credit score?

It depends on how poor your credit history is.

Serious issues like unpaid debts, CCJs and bankruptcies stay on your credit file for six years.

But if you have just had one slip up, and have quickly rectified it, your score should go back up within a few months.

Even taking out a new line of credit can cause your score to drop. But as long as you keep up repayments, your score should rise again within three months.

What can make my credit score go down?

Any default on credit payments can make your credit score drop.

And try to avoid making repeated applications for credit in a short space of time.

With every application you make, the lender will perform a ‘hard’ search on your credit history. This leaves a footprint on your credit report.

If you make a lot of rejected applications in a short space of time, lenders might see it as a sign that you’re financially struggling and it can affect your credit score.

Instead, run an eligibility check before you apply for any type of credit. This only requires a ‘soft’ credit search that lenders won’t see on your file and so won’t adversely affect your credit score.
