The best car finance deal comes from doing your research before you set foot in a showroom. Around 80 per cent of new cars in the UK are bought using some form of finance, according to the Finance and Leasing Association, and dealers often earn more commission from the finance arrangement than from the car sale itself. Knowing how to compare your options protects you from overpaying.
Short Summary
Car finance is available in several forms: hire purchase (HP), personal contract purchase (PCP), and personal loans. Each works differently and suits different circumstances.
Always compare deals using the APR (Annual Percentage Rate), not the monthly payment alone. A lower monthly payment over a longer term usually means you pay more in total.
Getting a personal loan quote from your bank before visiting a dealer gives you a benchmark figure. If the dealer cannot beat or match it, walk away.
Haggling is normal and expected. Dealers have room to move on both the car price and the finance terms, particularly near the end of a sales month.
What are the different types of car finance?
The three most common car finance types in the UK each work differently. Hire purchase (HP) means you pay a deposit and fixed monthly instalments; you own the car outright once the final payment is made. Personal contract purchase (PCP) has lower monthly payments because you are only financing the depreciation, but you face a large optional final "balloon" payment if you want to keep the car. A personal loan from a bank such as Barclays, HSBC or NatWest means you own the car from day one and are not tied to the dealer's finance terms.
| Finance type | Who owns the car during the term? | Typical deposit | Best for |
|---|---|---|---|
| Hire purchase (HP) | Finance company | 10% | Buyers who want to own the car outright |
| Personal contract purchase (PCP) | Finance company | 10% | Lower monthly payments; option to upgrade |
| Personal loan | You | None required | Good credit; maximum flexibility |
| Leasing | Leasing company | 3 months upfront | Drivers who always want a new car |
How do I compare car finance deals properly?
Always compare deals using the APR, which is the Annual Percentage Rate. This is the only figure that includes both the interest rate and any fees, which means it is the only honest like-for-like comparison. A dealer who quotes you a monthly payment or a daily rate is not giving you the full picture.
Get the total amount repayable in writing. This is the single most important number: how much you pay back in total across the full term. A £15,000 car financed at 9.9% APR over three years costs significantly less in total interest than the same car at 9.9% over five years, even though the monthly payment is lower. Always ask for both figures.
Be cautious when a salesperson extends the loan term to make payments look affordable. Paying £250 a month over 60 months instead of £330 a month over 36 months feels cheaper day-to-day but costs hundreds more overall.
Should I get a personal loan before visiting the dealer?
Yes. If your credit score is good enough to qualify, get a personal loan quote from your bank or a comparison site such as MoneySuperMarket before you visit any showroom. This gives you a concrete number to compare against the dealer's offer.
Most high-street banks including Barclays, HSBC, Halifax and NatWest offer personal loans for car purchases. Rates are typically lower than dealer finance for buyers with good credit. Taking a pre-approved loan quote into the dealership also gives you negotiating power: you can tell the dealer exactly what rate you are comparing against.
If the dealer's finance offer beats your loan quote on APR and total repayable, it may be the better option. If it does not, use your loan.
How do I haggle on car finance?
Treat the car price and the finance as two separate negotiations. First, agree the best possible price for the car itself. Then, and only then, discuss how you will pay for it. Dealers sometimes inflate one to offset a concession in the other.
Ask for extras to be included if the rate is close to your benchmark but not quite better. Free servicing, a full tank of fuel, floor mats, or an extended warranty all have real monetary value. If the dealer will not move on the rate, they can often move on these add-ons instead.
Visiting more than one dealership and getting competing finance quotes is one of the most effective tactics. A salesperson who knows you have an alternative offer is far more motivated to sharpen their terms.
What should I watch out for with car finance?
Check whether a PCP deal includes a guaranteed minimum future value (GMFV). This is the predicted value of the car at the end of the contract. If the car is worth less than the GMFV when you come to hand it back, the finance company absorbs the loss. If it is worth more, you can use that equity as a deposit on your next deal.
Mileage limits on PCP and leasing agreements can be costly. Exceeding the agreed annual mileage (typically 8,000 to 12,000 miles) triggers penalty charges, often 5p to 10p per excess mile. Be realistic about how much you drive.
Section 75 of the Consumer Credit Act 1974 protects buyers who finance a purchase of between £100 and £30,000 on a credit card or HP agreement. If the car is faulty or the dealer goes out of business, the finance provider shares liability. This protection does not apply to personal loans.
FAQ
What is the difference between HP and PCP car finance?
With hire purchase (HP), your monthly payments cover the full cost of the car minus your deposit, and you own the car outright at the end. With PCP, you only finance the depreciation, so monthly payments are lower, but you have to pay a large balloon payment to keep the car at the end. Most drivers on PCP hand the car back and use any equity as a deposit on the next deal.
Can I get car finance with bad credit?
Yes, specialist lenders including Black Horse and Moneybarn offer car finance to buyers with poor credit histories. The trade-off is a higher APR, sometimes above 20 per cent. If your credit score is low, consider improving it before applying, or look at guarantor finance. You can check your score for free with Experian, Equifax or TransUnion.
Is dealer finance always more expensive than a bank loan?
Not always. Some manufacturers offer 0% APR promotional deals on new cars, which are hard to beat. However, these deals often come with a higher car price or limited choice of model and colour. On used cars, dealer finance is frequently more expensive than a personal loan from a high-street bank.
What does APR mean in car finance?
APR stands for Annual Percentage Rate. It is the total cost of borrowing expressed as a yearly percentage, including interest and any mandatory fees. It is the standard measure used to compare finance deals on a like-for-like basis. A lower APR means the deal costs less in interest overall, assuming the loan term is the same.
Can I pay off my car finance early?
Yes, in most cases. Under the Consumer Credit Act, you have the right to settle a hire purchase or PCP agreement early. The lender may charge a settlement fee, typically one to two months' interest. Ask for a settlement figure in writing before you make any overpayments, as the calculation differs between lenders.
Is it better to put down a bigger deposit on car finance?
A larger deposit reduces the amount you borrow, which lowers your monthly payments and the total interest you pay. If you can afford to put down 20 per cent or more, it also makes you less likely to fall into negative equity, where the car is worth less than the outstanding finance balance.
