What Is a Credit Score? How to Check and Improve Yours

Your credit score is a three‑digit snapshot of how you’ve managed borrowing in the past. Lenders use it alongside your income and other data to decide if they’ll lend you money and at what rate. While a high score typically makes approval easier, a low score isn’t a life sentence, you can check your file without signing up for a paid service and take practical steps to improve it.

This guide explains what a credit score is, how to view it for free, and how you could boost it so you’re in the best position for car finance.

Please note: We do not act as financial advisors and cannot provide financial advice, there are firms that could assist you with this.

No single number: The UK’s three credit reference agencies (Experian, Equifax and TransUnion) each use different scales, so your scores will vary, and lenders have their own rules.

Free checks exist: Order a statutory report from each agency for free; apps need sign‑up and paid trials aren’t worth it.

Better habits matter: Get on the electoral roll, pay on time, keep usage low and fix errors.

Build credit: Open a bank account, put bills in your name and use a small credit card responsibly; low scores still have finance options.

How is a credit score calculated?

Your credit score is calculated from information in your credit report, such as payment history, credit utilisation (how much of your credit limit you use), the age of your accounts and any missed payments or court judgments. It doesn’t include your salary or non‑financial details like ethnicity or religion. Each of the UK’s three credit reference agencies (CRAs), Experian, Equifax and TransUnion compiles its own report based on data from lenders and public records. Lenders may also apply their own internal criteria, so a good score doesn’t guarantee approval, but it improves your chances.

You don’t have one single credit score

There is no universal UK credit score. Experian, Equifax and TransUnion each hold different data and use different scales. It’s therefore normal for your numbers to vary. Lenders might check one or more agencies, and they also apply their own scoring models. The table below shows how the ranges differ.

Credit reference agency

Scale

Bands (poor → excellent)*

Experian

0–999

0–720 poor, 721–880 fair, 881–960 good, 961–999 excellent

Equifax

0–1000

0–438 poor, 439–530 fair, 531–670 good, 671–1000 excellent

TransUnion

0–710

0–550 poor, 551–565 fair, 566–603 good, 604–710 excellent

How to check your credit score for free

Truly free – no account needed

Under the Consumer Credit Act and data‑protection laws, you have the right to a statutory credit report from each CRA once a year. It costs nothing and doesn’t require any account; you simply request the report online or by post. Experian’s statutory report is clearly labelled “free”, and you receive a secure passkey to view it. The Information Commissioner’s Office confirms that CRAs must provide your credit file free of charge and cannot make you sign up to a subscription. Links to request statutory reports:

Two other free resources are worth bookmarking. MoneyHelper, a government‑backed site, offers impartial guides on understanding credit reports and debts. Registering on the electoral roll (gov.uk/register‑to‑vote) is not only a legal requirement but also a quick way to strengthen your credit file because your details help lenders confirm your name and address.

Free – but you’ll need to create an account

Several services provide a credit score at no cost if you register: ClearScore (Equifax data), Credit Karma and MoneySavingExpert’s Credit Club (TransUnion data), and Experian’s free account. These are genuinely free and update monthly, but you must create an account and accept marketing offers. They may also display “pre‑approved” credit deals; ignore anything you don’t need.

Watch out for free trials

Some premium services, such as Experian’s CreditExpert or Equifax’s paid plan, advertise a 30‑day free trial but then convert to a subscription costing around £14.99 a month. Only sign up if you intend to cancel before the trial ends.

Does checking your score lower it?

Checking your own credit report is a soft search. Experian explains that soft searches are only visible to you and have no impact on your score. You can check as often as you like without harming your rating. Only “hard” searches – such as when you apply for credit – are visible to lenders and can temporarily reduce your score if there are many applications.

What’s a good credit score in the UK?

A “good” score varies by agency and lender. Generally, a good score means you’re likely to be accepted at mainstream rates, a fair score may result in higher interest or lower limits, and a poor score could lead to rejection or higher‑cost credit. The bands in the earlier table give a rough guide. Remember that lenders also look at affordability, employment and any defaults or court judgments; even a high score doesn’t guarantee approval.

How to improve your credit score

Improving your score takes consistent behaviour rather than quick hacks. Start with the steps below. Where possible, set up direct debits or reminders to automate good habits. This information is not financial advice, but designed to act as helpful tips. Please consult a financial advisor or a money advice charity for personal assistance on finances. 

Register on the electoral roll (4–6 weeks)

Registering to vote is one of the fastest ways to boost your score. When you join the electoral roll, your details appear on your credit report and help lenders verify your identity. You can register online in minutes and the update typically shows on your report within a month.

Always pay on time (ongoing)

Payment history is the single biggest factor in your score. Experian advises paying accounts on time and in full to demonstrate reliability. Missing or late payments stay on your file for six years. Set up direct debits for at least the minimum payment on credit cards and loans to avoid slipping.

Keep your credit utilisation low (immediate impact)

Using less than about 30% of your available credit shows you’re not over‑reliant on borrowing. Experian notes that keeping utilisation low can improve your score.

Check your report for errors and fix them (weeks)

Mistakes such as outdated addresses or misreported missed payments can drag down your score. Experian suggests checking your report regularly and disputing any errors. CRAs must investigate and correct mistakes, often within a month.

Space out applications and use soft searches (months)

Each hard search can lower your score a little. Use eligibility checkers that perform soft searches before applying, and avoid multiple applications in a short period.

Keep old, well‑managed accounts open (ongoing)

Closing an old credit card reduces your total available credit and can increase your utilisation ratio. Experian advises that long‑held, well‑managed accounts can improve your score. Unless a card has high fees, consider keeping it open.

Cut financial links to ex‑partners

If you’ve had a joint account or loan with someone, their credit behaviour can affect yours. Ask the CRA to remove the financial association once the account is closed.

Realistic timeline

Quick wins like joining the electoral roll or correcting errors can boost your score within a few weeks. Building a solid payment history takes three to six months, while serious marks such as defaults, county court judgments or debt relief orders remain on your report for six years but their impact reduces over time.

How to build a credit score from scratch

If you’ve never borrowed, you may not have a credit score at all. To build one:

  1. Get on the electoral roll.
  2. Open a bank account in your name and manage it well. Regular income and bill payments build trust.
  3. Put household bills in your name (e.g., mobile phone, utilities) and pay by direct debit. A consistent payment record helps.
  4. Use a credit‑builder product, such as a low‑limit credit card or a store card, and pay it off in full each month. Keep utilisation low.
  5. Limit applications and avoid payday loans; they signal risk.

How your credit score affects car finance

Your credit score influences the interest rate and deposit a lender may require for car finance. A higher score can give you access to lower rates and larger loan amounts, while a lower score may limit your options. However, specialist lenders can still help people with poor credit. For a deeper look at finance options with a low score, see Car Loans UK’s bad‑credit car finance guide. When you’re ready to see what you could borrow, our eligibility checker uses a soft search that won’t affect your score.

Where to get free help

If you’re struggling with debts or want impartial guidance, several organisations offer free support without requiring an account:

  • MoneyHelper (moneyhelper.org.uk) – government‑backed guidance on money and credit.
  • Citizens Advice – explains how lenders decide to give you credit and how long information stays on your file.

  • Information Commissioner’s Office: guidance on your right to access your credit file.
