If you are trying to improve your credit score in the UK, one term you will often hear is credit utilisation.
It sounds technical, but the concept is actually very simple. Credit utilisation refers to how much of your available credit you are currently using.
When utilisation becomes too high, it can negatively affect your credit score and make lenders less likely to approve future applications.
What Is Credit Utilisation?
Credit utilisation is usually calculated as a percentage of the credit you are using compared to the total credit available to you.
For example:
- Credit card limit: £2,000
- Balance owed: £1,500
Your utilisation would be:
£1,500 ÷ £2,000 = 75% utilisation
In simple terms, you are using three quarters of your available credit.
Credit Reference Agencies such as Experian, Equifax and TransUnion use this type of information when calculating your credit score.
Why High Credit Utilisation Can Be a Problem
From a lender’s perspective, high utilisation may suggest that someone is financially stretched.
Even if you are making all your payments on time, consistently using most of your available credit can still raise concerns.
Common reasons lenders dislike high utilisation include:
- It can indicate reliance on credit to cover everyday expenses
- It leaves little room for financial emergencies
- It increases the risk that balances will become unmanageable
As a result, high utilisation can lower your credit score and make future borrowing more difficult.
What Is Considered “High” Credit Utilisation?
There is no single rule that every lender follows, but many credit experts suggest the following rough guidelines:
- Below 30% – Generally considered healthy
- 30% to 50% – May start to affect your score
- Over 50% – Often viewed as high risk
For example, if your credit card limit is £3,000, keeping your balance below £900 would keep your utilisation under 30%.
Of course, this is easier said than done when you are already dealing with debt.
High Utilisation Does Not Always Mean You Are in Trouble
It is important to remember that credit utilisation is only one part of your credit profile.
You could still have high utilisation while:
- Making every payment on time
- Reducing balances gradually
- Managing multiple accounts responsibly
Many people see their utilisation rise temporarily during periods of financial pressure, particularly when dealing with rising living costs.
Ways to Reduce Credit Utilisation
If you are trying to improve your credit profile, lowering your utilisation can help over time.
Some common strategies include:
Paying Down Balances
The most obvious way to reduce utilisation is simply paying down existing balances.
Even small reductions can improve the ratio.
Spreading Balances Across Cards
If you have multiple credit cards, spreading balances across them can reduce the utilisation percentage on any single account.
Avoiding New Spending
If possible, avoiding additional spending on credit cards allows balances to fall faster.
Increasing Credit Limits
Sometimes lenders offer credit limit increases. This can lower your utilisation percentage if balances stay the same.
However, this only works if the additional credit is not immediately used.
High Utilisation and Debt Management
If you are currently managing debt, high credit utilisation is extremely common.
For example, someone with several credit cards may have balances close to the limits simply because they were relying on credit during difficult financial periods.
The important thing is progress over time.
Reducing balances gradually, keeping accounts up to date, and avoiding further borrowing can slowly improve both your utilisation ratio and your overall credit profile.
In Summary
High credit utilisation is one of the most common issues people face when trying to rebuild their credit.
While lenders often view high utilisation as a risk factor, it is not permanent. As balances fall and your reliance on credit reduces, your credit profile can improve significantly.
If you are currently dealing with debt, the focus should not be on achieving a perfect credit score overnight. Instead, it should be on steady progress and taking control of your finances one step at a time.
That approach may not be glamorous, but it is the one that actually works.
