PCP vs HP vs Personal Loan (UK): Which Cost Less?

PCP vs HP vs Personal Loan: Which Car Finance Actually Costs Less?

The dealer quoted £230 a month on PCP. A personal loan for the same car worked out at £320 a month. She almost signed for the PCP on the spot, until she asked what the total cost of actually owning the car looked like once the balloon payment was factored in, and the numbers stopped looking quite so simple.

Over 80% of new cars in the UK are now financed rather than bought outright, and PCP alone accounts for 60 to 70% of that. The monthly payment is what gets compared at the dealership. It’s rarely the number that actually matters most.

What each option actually is

Personal Contract Purchase (PCP) finances the car’s predicted depreciation, not its full value. You pay a deposit, then lower monthly payments covering the gap between the car’s price and its estimated future value, then face a choice at the end of the term: hand the car back with nothing further to pay (assuming you’re within the agreed mileage and condition), pay a lump sum balloon payment (the Guaranteed Minimum Future Value, or GMFV) to own it outright, or use any equity toward a new deal.

Hire Purchase (HP) is more straightforward. You pay a deposit, then fixed monthly instalments covering the full price of the car plus interest, spread across the term. There’s no balloon payment, and once the final instalment clears, you own the car outright.

A personal loan is separate from the car entirely. You borrow a lump sum from a bank or lender, buy the car outright with your own money on day one, and repay the loan on a fixed schedule. You own the car immediately, with no finance company involved in the vehicle itself.

A worked example — HP vs personal loan

Say you need £13,500 to finance a used car after your deposit. HP at 9.9% APR over 48 months works out to roughly £342 a month, a total of about £16,404, meaning £2,904 in interest across the term. The same £13,500 as a personal loan at 6.9% APR over the same 48 months comes to roughly £323 a month, a total of about £15,487, meaning £1,987 in interest, a saving of over £900 compared to the HP deal.

That gap exists because dealer-arranged finance rates are often higher than what a strong personal loan applicant can get directly from a bank or building society, sometimes 9 to 14% on dealer finance versus 4.5 to 7% on a best-buy personal loan for the same amount. The FCA has previously flagged that some dealers historically earned bigger commissions on higher-rate finance, which is exactly why comparing your own bank’s loan quote against the dealer’s offer before signing anything is worth the extra ten minutes.

Where PCP genuinely fits

PCP’s lower monthly payment isn’t a trick, it’s structurally lower because you’re only financing the car’s depreciation, not its full value. If you like changing cars every few years, don’t want to deal with selling a used car privately, and are comfortable with mileage limits, PCP can be a genuinely sensible way to always drive something newer for a predictable monthly cost. The balloon payment at the end means the total cost of actually owning the car outright often ends up comparable to, or sometimes higher than, HP or a loan, once you add the GMFV to what you’ve already paid monthly, so PCP tends to work out best specifically for people who plan to hand the car back or part-exchange rather than buy it outright at the end.

Where PCP catches people out is treating the low monthly figure as the full picture and drifting toward buying the car at the end anyway, without having budgeted for a balloon payment that can run into several thousand pounds. If there’s a real chance you’ll want to keep the car permanently, it’s worth comparing the total cost of PCP-then-buy against HP or a loan from the outset, rather than deciding at the point the balloon payment actually comes due.

The right nobody at the dealership mentions

Both PCP and HP agreements carry a statutory right under Section 99 of the Consumer Credit Act 1974 called voluntary termination, once you’ve paid 50% of the total amount payable under the agreement, you can hand the car back and walk away from the remaining payments owing nothing further, provided the car is in reasonable condition. On PCP specifically, that 50% figure is calculated against the total amount payable including the balloon, so it typically takes longer to reach than on an equivalent HP deal, since the balloon inflates the total figure you’re measuring against. A personal loan carries no equivalent right, since it isn’t secured against the car in the same way, you own the vehicle from day one and the loan is simply a separate unsecured debt you’re repaying regardless of what happens to the car.

The protection you lose with a personal loan

Dealer-arranged PCP and HP finance for purchases between £100 and £30,000 come with Section 75 protection under the Consumer Credit Act, meaning the finance company is jointly liable if the car turns out to be faulty or misrepresented. Buying a car outright with a personal loan and paying the seller directly doesn’t carry this same protection, if a private seller misrepresents the car, your claim is against them personally, not against your bank. This matters more when buying privately or from a smaller independent dealer than when buying from a large franchised dealership with its own reputation and complaints process to answer to.

How to actually decide

If you want to own the car outright, plan to keep it for years, and can get a competitive personal loan rate, a loan is usually the cheapest route, provided your credit qualifies for a rate meaningfully below typical dealer finance. If you like the flexibility of changing cars regularly and want the lowest monthly outgoing without committing to full ownership, PCP fits that pattern well, as long as you go in accepting you likely won’t own the car unless you separately budget for the balloon. HP sits in between, no balloon surprise, ownership guaranteed at the end, but rarely the cheapest option once you’ve actually shopped a personal loan rate against it. Compare the APR across all three, not just the monthly payment, before signing anything at the dealership.

Frequently asked

Is PCP always cheaper than HP?
The monthly payment is almost always lower, but the total cost of ownership, including the balloon if you buy the car, is often similar to or higher than HP. Whether PCP is genuinely cheaper depends entirely on whether you plan to hand the car back or buy it outright.

Can I get voluntary termination on a personal loan car purchase?
No. Voluntary termination under Section 99 only applies to regulated HP and PCP agreements. A personal loan is unsecured general credit, not tied to the vehicle in the same legal way, so this specific protection doesn’t apply.

Should I always shop my own personal loan quote before accepting dealer finance?
Generally yes, particularly if you have a strong credit profile. Dealer finance rates aren’t always the most competitive available, and even a small difference in APR can mean a meaningful saving over a three- to five-year term.

What happens if I exceed the mileage limit on a PCP deal?
You’ll typically face an excess mileage charge per mile over the agreed limit when you hand the car back, which can add up to a significant amount if you’ve substantially exceeded what was agreed. If your driving needs are unpredictable or high-mileage, PCP’s mileage restriction is worth weighing carefully against HP or a loan, neither of which carries this limitation.

Is a used car cheaper to finance than a new one?
Generally yes in absolute terms, since the amount financed is smaller, though the APR itself can sometimes be higher on used car finance depending on the lender and the age of the vehicle. Always compare the total cost, not just the headline rate, across new and used options if you’re weighing both.
