What is a personal loan?
A personal loan is a lump sum you borrow from a bank, building society, or specialist lender and repay in fixed monthly instalments over an agreed term. In most cases the amount, the term, and the monthly payment are set when you sign, which makes budgeting straightforward compared with revolving credit.
People use personal loans for one-off costs: buying a car, funding home improvements, covering a wedding, or consolidating several existing debts into one payment. Because you receive the money upfront and repay on a schedule, it suits a defined expense rather than ongoing day to day spending.
Secured versus unsecured loans
An unsecured personal loan is not tied to an asset. The lender relies on your credit history, income, and affordability checks. If you miss payments your credit score suffers and the lender can take recovery action, but your home is not automatically at risk.
A secured loan is backed by something you own, often your home. That security can allow larger sums or lower headline rates, but the asset can be repossessed if you do not keep up repayments. Treat secured borrowing as a last resort for consolidating unsecured debt.
How APR works
APR, the annual percentage rate, includes the interest on the money you borrow plus certain compulsory fees, so it is the fair way to compare loans on a like-for-like basis. The figure you see advertised is usually the representative APR, which UK rules require lenders to offer to at least 51 percent of accepted applicants.
Your personal rate may differ depending on your credit profile, the amount, and the term. Use the personal loan calculator to see how a representative APR translates into monthly payments and total interest before you apply.
Fixed versus variable rates
Most personal loans in the UK have a fixed rate, so your monthly payment stays the same for the whole term. That predictability helps with household budgeting and protects you if wider interest rates rise during the loan.
Some products have a variable rate, which can move up or down with market rates. Your payment can change over time, which adds uncertainty. Check the agreement carefully if you are offered a variable deal.
What affects the rate you are offered
Lenders set your rate based on several factors:
- Credit history: a stronger record usually unlocks lower rates
- Amount borrowed: larger loans sometimes sit in lower rate bands within set limits
- Term: longer terms can carry slightly different pricing
- Income and outgoings: affordability checks confirm you can meet repayments
Two people applying for the same advertised product can receive different APRs. That is why eligibility or quotation tools, which use a soft search, are useful before a formal application.
Eligibility and credit checks
Before approving a loan, lenders review your credit file and verify income against your regular outgoings. A soft search quotation or eligibility check lets you see likely rates without affecting your score, because other lenders cannot see it on your file.
A full application triggers a hard search, which is recorded and can dip your score slightly for a short period. Multiple hard searches in quick succession can signal distress to lenders, so use soft checks to narrow your options first.
Repaying early
Regulated personal loan agreements allow early repayment. Lenders can charge an early settlement fee, typically up to one to two months of interest, but paying off the balance early usually cuts the total interest you pay because you stop accruing future charges.
Ask for a settlement figure before you pay. If you have spare cash, compare early loan repayment with other priorities such as building an emergency fund or clearing expensive revolving credit first.
Loans versus alternatives
A personal loan is not always the cheapest or simplest option:
- 0 percent credit cards: for smaller, short term spending, a purchase or balance transfer card at 0 percent can beat a loan if you clear the balance before the promotional period ends. See our credit card minimum payments guide for why minimum payments are costly once a promotional rate expires.
- Overdrafts: arranged overdrafts suit very short term gaps but daily or monthly charges can exceed loan APRs if the balance lingers. They are poor for planned, longer term borrowing.
- Debt consolidation: rolling several unsecured debts into one loan can simplify payments, but a longer term may increase total interest. Moving unsecured debt onto a secured loan puts your home at risk if repayments falter.

Frequently Asked Questions
You borrow a fixed amount and repay it in equal monthly instalments over an agreed term, usually one to seven years, with interest added. Most personal loans are unsecured, so they are not tied to an asset, and the rate is set when you take the loan.
It is the advertised annual cost of a loan, including interest and compulsory fees, that the lender must offer to at least 51 percent of customers who are accepted. Because it is only the majority, not everyone, your personal APR could be higher.
An unsecured loan is based on your creditworthiness and is not linked to an asset. A secured loan is backed by something you own, often your home, which can allow a larger amount or a lower rate, but the asset can be repossessed if you do not keep up payments.
There is no single cut-off, as each lender sets its own criteria, but a stronger credit history and stable income improve your chances and the rate offered. Using a soft-search eligibility check first lets you gauge your odds without harming your score.
Amounts vary by lender, commonly from a few hundred pounds up to around 25,000 to 50,000 pounds for unsecured loans, subject to affordability. Larger sums usually need a secured loan. What you are offered depends on income, outgoings, and credit history.
Yes, regulated personal loans allow early repayment. The lender can charge an early settlement fee of up to one to two months of interest, but settling early still usually reduces the total interest you pay over the life of the loan.
A quotation or eligibility check uses a soft search, which is not visible to other lenders and does not affect your score. A full application uses a hard search, which is recorded and can lower your score slightly for a short time.
It can simplify several debts into one payment and sometimes lower the rate, but extending the term can increase the total interest, and moving unsecured debt onto a secured loan puts an asset at risk. Compare the total cost before deciding.
