Improving your credit before applying
Your credit score isn’t fixed. There are practical steps you can take to improve your credit profile before applying for a mortgage, and even small improvements can open up better rates and more lender options. Here’s what actually works.

What common errors should you dispute?
- Wrong address or addresses you’ve never lived at
- Incorrect date of birth
- Financial links to people you’re no longer connected to (e.g. an ex-partner)
- Debts marked as unsatisfied when you’ve paid them
- Accounts that don’t belong to you (possible identity fraud)
- Late payments incorrectly recorded
- Raise a dispute directly with the credit agency
- They must investigate within 28 days
- Provide supporting evidence (payment receipts, correspondence)
- The agency will correct or remove inaccurate entries
Register on the electoral roll
This is one of the quickest and easiest ways to improve your credit profile. Being registered on the electoral roll at your current address helps lenders verify your identity and confirms you’re stable at that address.
If you’re not registered (or registered at a previous address), you can do it online at gov.uk/register-to-vote. It typically updates on your credit file within a few weeks.
How to reduce existing debt before applying
- Aim to use less than 30% of your available credit limit
- High utilisation signals financial stress to lenders
- Paying off balances in full each month is ideal
Should you close unused credit accounts?
This is nuanced. Having unused credit available can actually help your score by keeping your overall utilisation ratio low. But too many open accounts can concern lenders who worry about potential debt.
As a general rule: keep one or two credit cards you’ve had for a long time (they demonstrate a stable credit history) and close any you don’t use, especially store cards and newer accounts. Don’t open new cards just to improve your credit mix — the hard search and new account will temporarily lower your score.

Building credit from scratch
Register on the electoral roll
The foundation of any UK credit file. Do this first.
Get a credit-builder credit card
Use it for a small regular purchase (e.g. fuel or groceries) and pay the full balance every month. This builds a history of responsible borrowing at no cost to you.
Set up a mobile phone contract
Monthly phone contracts are reported to credit agencies. Paying on time each month adds to your positive payment history.
Consider Experian Boost or similar services
Some credit agencies let you link regular payments (council tax, streaming services, savings) to your credit file. This can add positive data that wouldn’t normally appear.
Be patient
Building a credit history takes time. Six to twelve months of responsible borrowing and on-time payments will make a real difference to your file.
