Understanding credit

Credit is a tool, and like any tool it works best when you understand it. This guide explains how UK credit scores work, what’s in your report, and the habits that keep your score healthy.

Score vs report

Your credit report is the actual record — every account, payment, and credit application in your history. Your credit score is a number calculated from that report by credit reference agencies. Lenders don’t usually see “your score”; they receive the report data and apply their own rules. The score is a useful shorthand for how you look.

What’s in your report

• Credit accounts — credit cards, loans, mortgages, phone contracts, their limits and balances
• Payment history — whether payments were on time or late (late payments can stay for six years)
• Credit applications — recent “hard searches” when you applied for credit
• Public records — insolvencies, CCJs, IVAs, bankruptcies
• Financial associations — people you’re financially linked to (e.g. joint accounts), whose records lenders may consider
• Electoral roll — being registered to vote helps verify your identity

What lenders actually care about

Lenders want to answer two questions: will you pay it back, and can you afford it? They look at payment history, how much of your available credit you’re using, how often you apply, how long your accounts have been open, and your affordability (income minus outgoings).

Habits that keep you healthy

• Pay on time — missed payments are the biggest red flag
• Use a small slice of your limit — using under 25–30% of your credit limit looks responsible
• Don’t apply in bursts — several hard searches in a few weeks look risky
• Keep old accounts open — account age adds history
• Be on the electoral roll — an easy, free boost
• Clear balances, don’t just make minimums — interest compounds against you otherwise

Fixing mistakes

Errors happen — a wrongly reported late payment, a settled account still shown as open, or a closed card showing a balance. Check all three agencies (Experian, Equifax, TransUnion) for free and raise a dispute with the agency or lender to correct errors. Disputes must be investigated.

Credit myths to ignore

• “Checking my score lowers it” — only applications (hard searches) leave traces
• “I need to pay to fix my score” — free tools and diligence do the job
• “Closing cards helps” — it can hurt, by shortening your history
• “One score everywhere” — you have a different score at each agency

Credit and your big goals

A good credit record unlocks better rates on mortgages, loans and cards — worth thousands over time. Read our understanding mortgages guide for how it affects home buying, and reducing debt for escaping high-interest balances.

Plan around it

If you’re borrowing, the loan calculator shows the true cost at different rates, and the budget calculator helps you keep payments affordable.
