How to close a credit card without hurting your credit score in the UK

Closing a credit card is not always the right move — even if you no longer use it. Under some circumstances, closing a card can lower your credit score by shortening your credit history or increasing your credit utilisation ratio. Understanding the mechanics helps you make the right decision.

Why closing a credit card can reduce your score

Two mechanisms explain the potential score impact. First, credit history length is a factor in credit scores — a card you have held for several years contributes to the length of your credit history. Closing it removes that history from your active accounts, potentially shortening your average account age. Second, closing a card reduces your total available credit, which increases your credit utilisation percentage if you have balances on other cards.

Example: you have two credit cards, each with a £2,000 limit. You use one for £500 per month — 25% utilisation on that card, 12.5% overall. If you close the unused card, your overall utilisation jumps to 25%, which is above the threshold most scoring models reward.

When it is worth closing a card anyway

Despite the potential score impact, there are valid reasons to close a credit card: if the card has an annual fee that is not offset by benefits, if the card is linked to problematic spending habits, if the card is associated with a joint credit agreement you want to end, or simply to simplify your finances. A moderate, temporary score reduction is worth accepting for these benefits.

How to minimise the impact when closing

• Pay the balance to zero before closing — never close a card with an outstanding balance
• Wait until your credit score is in good shape before closing — do not close during a period of active credit applications
• Keep your oldest cards open if possible — the account with the longest history has the most impact on credit history length
• If keeping multiple cards, use each one occasionally to maintain activity
• After closing, monitor your utilisation rate — reduce balances on other cards if utilisation increases significantly

The process of closing a credit card

To close a credit card, pay the balance to zero, then contact the card provider by phone or secure message to request closure. Ask for written confirmation that the account is closed and settled. Check your credit file with all three agencies a few weeks later to confirm the closure is recorded correctly.
