Buying a car is one of the biggest purchases most people make — and how you finance it can cost or save you thousands. Personal loan or dealer finance? PCP or HP? This guide compares every car finance option available in the UK in 2025, with real numbers to help you choose the most cost-effective route.
Car Finance Options in the UK
There are five main ways to finance a car in the UK. Each works differently and suits different situations. Here’s a quick overview before we go into the detail:
| Finance Type | Do You Own the Car? | Monthly Cost | Flexibility | Best For |
|---|---|---|---|---|
| Personal Loan | Yes (from day one) | Medium | High | New or used car, best credit |
| PCP (Personal Contract Purchase) | No (until balloon payment) | Lowest | Medium | New cars, regular upgraders |
| HP (Hire Purchase) | No (until final payment) | Medium-High | Low | Owning outright, no balloon |
| Leasing (PCH) | Never | Low-Medium | Low | Drivers who always want new |
| Credit Card | Yes | Variable | High | Small purchases under £5k only |
Personal Loan vs Dealer Finance — Which Is Cheaper?
Dealer finance is convenient — but it’s almost never the cheapest option. Dealers often mark up the finance rate or receive commission from the lender. A personal loan from a bank or online lender typically offers a significantly lower APR.
Here’s a comparison on a £12,000 used car over 4 years:
| Finance Option | APR | Monthly Payment | Total Interest | Total Cost |
|---|---|---|---|---|
| Best personal loan | 5.8% | £280 | £1,440 | £13,440 |
| Typical personal loan | 9.9% | £302 | £2,496 | £14,496 |
| Dealer HP finance | 12.9% | £321 | £3,408 | £15,408 |
| Dealer PCP | 8.9% | £180 + balloon | ~£2,200 | £14,200 (if balloon paid) |
| High street bank loan | 7.5% | £290 | £1,920 | £13,920 |
A personal loan at 5.8% saves £1,968 in interest compared to dealer HP at 12.9% over 4 years. Before accepting any dealer’s finance offer, use our loan calculator to check what a personal loan would cost — then negotiate or switch accordingly.
Understanding PCP Finance
PCP (Personal Contract Purchase) is the most popular car finance option in the UK. You pay lower monthly instalments because you’re only financing the depreciation of the car — not its full value. At the end of the contract (typically 3 years) you have three options:
- Return the car — Walk away with nothing owed (if within mileage limits)
- Pay the optional final payment (Guaranteed Minimum Future Value / GMFV) to own it outright
- Part-exchange — Use any equity above the GMFV as a deposit on your next car
PCP works well if you always want a new car every 3 years and don’t mind never fully owning it. It works poorly if you drive high mileage (excess mileage charges apply) or if car values fall significantly, leaving no equity at end of term.
Understanding HP Finance
HP (Hire Purchase) is simpler than PCP — you pay fixed monthly instalments over an agreed term and own the car outright when the final payment is made. There’s no balloon payment and no mileage restrictions. Monthly payments are higher than PCP because you’re paying off the full value of the car, but you own it at the end without any further decisions required.
New Car vs Used Car — Finance Considerations
New cars depreciate fastest in the first 1–3 years — typically losing 40–60% of their value. This makes financing a new car inherently more expensive in real terms, even if the monthly payment looks similar. A 2–3 year old used car that has already taken the depreciation hit gives you significantly more value per pound spent, especially when financed through a personal loan at a competitive rate.
Car Finance FAQ
What credit score do I need for car finance?
There’s no universal minimum, as lenders have their own criteria. A score of 600+ (Experian scale) will typically access standard rates. Scores above 700 unlock the best deals. Below 500, you may face very high rates or refusals — a guarantor or specialist lender may be needed.
Can I pay off car finance early?
Yes — under the Consumer Credit Act, you have a right to settle car finance early at any time. Lenders can charge up to 1–2 months’ interest as an early settlement fee, but early settlement almost always saves money overall if you can afford the lump sum.
Is 0% car finance genuinely free?
0% finance deals on new cars are real — the manufacturer subsidises the interest to boost sales. However, 0% deals are typically only available on specific models, require a substantial deposit, and may not include much negotiating room on the purchase price. Always check whether you could buy for less by negotiating a cash discount and financing separately.
Should I buy with cash or finance a car?
If you can afford to pay cash, the maths usually favours paying cash for a used car — you avoid all interest costs. For new cars, 0% finance may make sense if you’d otherwise dip into investments earning more than 0%. For most buyers, a personal loan at 5–7% on a quality used car represents the best balance of value and cost.
