Unsecured personal loans are the cheapest mainstream borrowing for most UK adults — typically 6–12% APR for prime borrowers in 2026, well below credit card rates. But the rate you see in advertising is rarely the rate you're actually offered, and the small print on fees, early repayment and credit-report impact varies more than the headline rate suggests. This guide walks through what to check before you click 'apply'.
FCA rules require lenders to quote a 'representative APR' that at least 51% of accepted applicants will be offered. The other 49% can pay more — sometimes much more. Your personal APR depends on your credit file, income, employment and existing debt.
Always use a soft-search eligibility checker (most major comparison sites and several lenders offer one) before submitting a full application. A soft search shows what you're likely to be offered without leaving a footprint on your credit file.
A full loan application leaves a hard search on your credit file. One or two hard searches in a year are normal and have minimal impact. Five or more in a few months looks like 'credit hunger' and lowers your score for around 12 months.
If you're shopping around for a loan, do all your full applications within a 14-day window. Most credit-scoring algorithms treat this as a single rate-shopping event rather than multiple separate attempts.
Arrangement fees: usually £0 for unsecured personal loans, but secured/homeowner loans often add 1-5%. Insurance: optional credit insurance (PPI's quieter successor) is rarely good value — decline it.
Early repayment charges: under the Consumer Credit Act, lenders can charge up to 1 month's interest if you repay early (or 2 months on loans over £8,000 with more than 12 months remaining). Many lenders waive this — check before signing.
Every regulated personal loan comes with a Standard European Consumer Credit Information (SECCI) document. The four numbers that matter: total amount of credit (what you actually receive), total amount payable (what you'll pay back including all interest and fees), APR, and the number and amount of repayments.
If total amount payable is more than 1.5x the total amount of credit on a 5-year loan, the rate or fees are high. Run the comparison tool to see if a different lender is cheaper before signing.
For under £3,000 with a 12-24 month payoff, a 0% purchase credit card or 0% balance transfer (with a 2-3% fee) usually beats a personal loan. The hard part is making sure you clear it before the 0% ends.
For £5,000-£25,000 over 2-7 years, a personal loan is almost always cheapest. Authorised overdrafts at 35-40% EAR are the most expensive mainstream credit — only use as short-term liquidity, never for planned spending.
Most UK lenders accept Experian scores of 700+ for prime rates. 600-700 will get you offers but at higher APRs. Below 600, expect APRs of 25%+ if you're accepted at all.
Yes — under the Consumer Credit Act you have the right to repay any regulated loan early. The lender can charge up to 1-2 months' interest as a fee, but many waive it.
Rarely. APRs are typically 35-50% and they put your guarantor's credit and assets at risk. Improve your own file with a credit-builder card for 6-12 months instead if you can wait.
Soft search = visible only to you, no impact on credit score. Hard search = visible to lenders for 12 months, small temporary score dip. Use soft-search eligibility checks before any full application.
