6 Ways to Improve Your Credit Score
28th October 2025
A good credit score can make everyday finances a little easier, from setting up a phone contract to applying for a loan or renting a home. If your score isn’t where you’d like it to be, don’t worry. Small, steady changes can make a big difference over time.
What is a credit score?
A credit score is a number that shows how reliable you are when borrowing money. Think of it as a kind of trust score. Lenders use it to help decide whether to lend you money and on what terms. In the UK, credit scores usually range from 0 to around 999, depending on the credit reference agency you use, such as Experian, Equifax, or TransUnion.
Why does your credit score matter?
Your credit score isn’t just about getting a loan. A higher score can make it easier to get approved for a mortgage, rent a flat, or set up a mobile phone contract. Some utility providers and insurers also check your credit history when setting up payments. A lower score doesn’t mean you can’t borrow, but it might mean fewer options or stricter conditions.
How is your credit score calculated?
Credit reference agencies look at several factors, including:
- Payment history: Do you pay your bills on time?
- Credit use: How much of your available credit do you use?
- Credit history: How long you’ve had accounts open.
- Recent applications: Have you applied for several loans or cards recently?
These details together help build a picture of how you manage money.
6 simple ways to boost your credit score
1. Get on the electoral roll
Registering to vote helps lenders confirm your name and address. It’s a simple step that makes it easier for them to verify who you are and can boost your score. You can register to vote online at the official government website.
2. Start building a credit history
If you’ve never borrowed before, lenders don’t yet know how you handle credit. You can start small by using a credit-builder card for small purchases and paying it off in full each month, setting up a mobile phone contract in your name, or opening a current account and managing it responsibly. The goal isn’t to borrow more, just to show you can manage money well.
3. Pay bills on time and keep your credit use low
Set up direct debits to make regular payments on time. This prevents missed bills from lowering your score. Try not to use more than 30 percent of your available credit each month. For example, if your limit is £1,000, keep your balance below £300 where possible.
4. Avoid applying for too much credit at once
Each new credit application leaves a mark on your report. Too many in a short time can lower your score and make you look overextended. If you just want to check your eligibility, look for lenders that offer a soft search. This lets you see your chances without affecting your score.
5. Check your credit report for mistakes
Even small errors can hurt your score. Check your credit report regularly for things like old or incorrect addresses, financial links with people you’re no longer connected to, or missed payments that weren’t actually missed. You can check your report for free with Experian, Equifax, or ClearScore.
6. Be careful with joint accounts
If you share a loan, mortgage, or overdraft, your credit file is linked with the other person’s. If they miss payments or have poor credit, it can affect your score too. If you’re no longer financially linked, you can ask credit agencies to remove the connection.
How long does it take to improve a credit score?
Improving your credit score takes time. There are no quick fixes. Positive habits like paying on time or keeping credit balances low can show results within a few months. Bigger improvements, such as clearing debts or correcting errors, may take longer. The key is consistency and patience. Every good habit adds up.
Final thought
Improving your credit score is about steady, sensible choices. From registering to vote to paying bills on time, each small step builds trust with lenders over time. Don’t worry if change doesn’t happen overnight. Stay consistent, check your reports often, and keep going. Over time, you’ll see your score improve.
Before you borrow
A higher credit score can open doors, but borrowing isn’t always the right choice for everyone.
