How Personal Loans Work in the UK

A personal loan is a fixed-sum borrowing agreement where you receive a lump sum and repay it in equal monthly instalments over an agreed term. Unlike a credit card, the interest rate and monthly payment are fixed from day one, making budgeting straightforward.

When you apply, the lender assesses your creditworthiness — including your credit score, income, employment status, and existing debts — and offers you a personalised interest rate. If approved, the money is usually paid into your bank account within 1–3 business days.

Understanding APR on a Personal Loan

APR (Annual Percentage Rate) is the standardised measure of the cost of borrowing, expressed as a yearly percentage. It includes both the interest rate and any mandatory fees (such as arrangement fees), making it the fairest way to compare loans from different lenders.

Representative APR Explained

Lenders advertise a "representative APR" which, by FCA rules, must be offered to at least 51% of successful applicants. The remaining 49% may receive a higher rate. This means you could apply and be offered a worse rate than advertised — always use eligibility checkers first.

Example: £10,000 loan at 9.9% APR over 3 years Monthly repayment: approximately £320 | Total repaid: £11,520 | Total interest: £1,520

Personal Loan Amounts and Terms

Most UK unsecured personal loans fall within these parameters:

Early Repayment and Settlement

You are entitled under the Consumer Credit Act to settle a personal loan early at any time. However, most lenders apply an Early Repayment Charge (ERC) of up to 58 days' interest (roughly 1–2 months). To settle early, contact your lender and request a settlement figure, which is valid for 28 days.

Secured vs Unsecured Personal Loans

Unsecured loans are the most common personal loans in the UK. They are not tied to any asset, so approval depends entirely on your credit profile. If you default, the lender cannot automatically seize your property, but they can pursue you through the courts.

Secured loans (also called homeowner loans or second-charge mortgages) are tied to your property. They typically offer lower rates, longer terms, and higher amounts than unsecured loans, but your home is at risk if you fail to keep up repayments. Only consider secured loans if you are certain you can afford the payments.

Guarantor Loans

If your credit score is poor, a guarantor loan may be an option. A guarantor (usually a parent or close friend with good credit) agrees to cover your repayments if you default. Rates are higher than standard loans but lower than subprime unsecured loans. Note: if you miss payments, the guarantor's credit score is also damaged.

Impact on Your Credit Score

A personal loan application creates a hard search on your credit file, temporarily reducing your score. However, responsibly managing a loan (paying on time each month) can improve your score over time. Before applying, use a lender's eligibility checker — these use soft searches which do not affect your credit file.

Frequently Asked Questions

What is a representative APR on a personal loan?
Representative APR means at least 51% of accepted applicants receive that rate or lower. The remaining 49% may be offered a higher rate based on their individual credit assessment. This is an FCA requirement to prevent misleading advertising. Always check your personalised rate using an eligibility checker before applying.
What is a good personal loan APR in the UK?
In the UK, APRs below 10% are excellent and usually only available to those with very strong credit histories. Rates between 10–15% are competitive for most borrowers. Anything above 20% APR is expensive and should prompt you to consider improving your credit before borrowing, or exploring 0% purchase credit cards for smaller amounts.
How much can I borrow with a personal loan in the UK?
Most UK personal loans are offered between £1,000 and £25,000. Some specialist lenders go up to £50,000. The amount you are offered depends on your income (typically loans up to 3–5x your annual salary), existing debt commitments, and credit profile. Many lenders offer better rates on amounts of £7,500–£15,000.
Can I repay a personal loan early?
Yes. Under the Consumer Credit Act 1974, you have the legal right to repay any personal loan early at any time. Lenders may charge an early repayment penalty of up to 58 days' interest on the outstanding balance. Contact your lender for a settlement figure, which is valid for 28 days from the date of the statement.
Does applying for a personal loan affect my credit score?
Yes, a full credit application creates a hard footprint on your credit report, which can temporarily lower your score by a few points. Multiple applications in a short period can look like financial distress to lenders. Use eligibility checkers first — these use soft searches which have no impact on your score. If accepted, managing the loan responsibly will improve your score over time.
What is the difference between a secured and unsecured personal loan?
An unsecured personal loan requires no collateral. Approval is based on your credit score, income, and financial history. If you default, the lender pursues you through debt collection and potentially court action, but cannot automatically take your property. A secured loan is tied to your home — lower rates but your property is at risk if you default. Most standard personal loans in the UK are unsecured.
