Everything you need to know about personal loan vs car finance uk in the UK.
When buying a car in the UK, the two most common financing methods are a personal loan from a bank or lender and dedicated car finance arranged through the dealership. Each has distinct advantages and drawbacks, and the cheapest option depends on your credit profile, the car you are buying, and how long you want to keep it.
In 2024, around 90% of new cars and over 50% of used cars in the UK are bought on some form of finance. Yet many buyers accept whatever the dealer offers without comparing alternatives. Taking the time to understand your options could save you thousands of pounds over the life of the agreement.
With a personal loan, you borrow a fixed amount from a bank or lender and use it to buy the car outright. You own the car from day one, which means you can sell it, modify it, or change your insurance without any restrictions from a finance company. Loan rates for borrowers with good credit start from around 3–5% APR for amounts between £7,500 and £15,000.
The main advantage of using a personal loan is ownership and flexibility. You also have more negotiating power at the dealership because you are effectively a cash buyer, which can help you negotiate a lower purchase price. Some dealers offer discounts of 5–10% for cash or finance-free purchases.
Hire purchase spreads the cost of the car over a fixed term, typically 2–5 years, with equal monthly payments. You pay a deposit (usually 10–20% of the car's value) and make monthly payments until the full amount plus interest is repaid. You do not own the car until the final payment is made, and a small option-to-purchase fee (typically £100–£200) may apply.
HP rates from dealers typically range from 5–10% APR, though some manufacturers offer promotional rates as low as 0% on selected new models. The total amount repayable is clearly stated upfront, and there are no mileage restrictions. HP is straightforward and easy to understand, making it a popular choice for used car purchases.
💡 Under HP, you can exercise your right to voluntary termination once you have paid at least half the total amount due. This lets you hand back the car and walk away without further payments, which can be useful if your circumstances change or the car is depreciating faster than expected.
PCP is the most popular form of car finance in the UK, accounting for over 80% of new car finance deals. It works differently from HP: you pay a deposit and lower monthly payments, but a large balloon payment (the guaranteed minimum future value, or GMFV) is deferred to the end of the agreement.
At the end of a PCP deal, you have three choices: pay the balloon payment and keep the car, hand the car back with nothing more to pay (provided it is within agreed mileage and condition limits), or use any equity above the GMFV as a deposit on a new PCP deal. Monthly PCP payments are typically 30–40% lower than HP for the same car because you are only financing the depreciation, not the full value.
However, PCP has significant downsides. You never own the car unless you pay the balloon. Exceeding the agreed mileage limit (typically 8,000–12,000 miles per year) incurs charges of 5–15p per excess mile. Damage beyond fair wear and tear results in additional charges. PCP can also be more expensive overall if you keep rolling from one deal to the next.
Consider a car costing £20,000 with a £2,000 deposit, financed over 4 years:
In this example, the personal loan is the cheapest option for someone who wants to own and keep the car. PCP is cheapest monthly but costs the most overall if you want to keep the vehicle.
⚠️ Be very cautious of PCP deals with low monthly payments but high balloon payments. If the car is worth less than the balloon payment at the end of the term (known as negative equity), you cannot use it as a deposit for a new deal and may feel trapped into paying the balloon or accepting unfavourable terms on a replacement.
Choose a personal loan if you want to own the car outright, plan to keep it for many years, drive high mileage, or want the negotiating power of being a cash buyer. Choose HP if you want straightforward financing with ownership at the end and cannot access a competitive personal loan rate. Choose PCP if you like changing cars every 2–4 years, drive relatively low mileage, and are comfortable never owning the vehicle.
If your credit score is strong enough to access competitive personal loan rates (below 5–6% APR), a loan almost always works out cheaper than dealer finance for buyers who plan to keep the car. If your credit is less strong, dealer finance may offer more competitive rates, especially on new cars with manufacturer-subsidised deals.
A loan broker can compare personal loan rates across the market and help you calculate whether a loan or dealer finance is cheaper for the specific car you are looking at. They can also help if you have poor credit and need specialist options.
