Car finance is one of those things that sounds straightforward until you’re sitting in a dealership, someone slides a document across the desk, and you realise you’re not entirely sure what you’re signing. I’ve spoken to enough drivers who’ve been stung by end-of-contract charges to know this isn’t a fringe problem. PCP and HP agreements between them account for the vast majority of new car sales in the UK, yet the differences between them, and the traps buried inside each, remain genuinely confusing for most buyers. This guide cuts through the noise.
What HP and PCP actually are
Hire Purchase (HP) is the simpler of the two. You borrow the full value of the car, minus your deposit, and pay it back in equal monthly instalments over an agreed term, typically two to five years. Once the final payment is made, you own the car outright. No balloon payment, no optional final payment, no mileage allowance to worry about. The monthly costs are higher than PCP for the same car, but you’re building equity the whole time.
Personal Contract Purchase (PCP) works differently. The lender sets a Guaranteed Minimum Future Value (GMFV), which is a prediction of what the car will be worth at the end of the contract. You only finance the difference between the car’s purchase price and that predicted residual value, plus interest. Monthly payments are lower as a result. At the end of the term, you have three options: hand the car back, use any equity (if the car is worth more than the GMFV) as a deposit on a new deal, or pay the optional final payment to own it outright.
The optional final payment is where many buyers get confused. It’s not a penalty. It’s simply the GMFV, the amount the lender predicted the car would be worth. On a popular family hatchback with strong residuals it might be reasonable. On a niche model or a car in a rapidly shifting market (electric vehicles being the obvious current example), the GMFV set three years ago can look very different from what the car actually fetches. If the car is worth less than the GMFV, you just hand it back and walk away. If it’s worth more, that equity is yours to use.
How mileage penalties work in practice
PCP agreements set a mileage limit for a reason. The GMFV is calculated partly based on how many miles the car will have covered. Go over that limit and the lender’s predicted residual value falls, so they charge you for the difference, typically between 6p and 15p per mile depending on the lender and vehicle. That sounds trivial until you do the maths. Ten thousand miles over a three-year contract at 10p per mile is £1,000 coming out of your pocket when you hand the car back.
I’d always recommend being honest with yourself about your annual mileage before signing. If you cover 15,000 miles a year and the deal is written around 10,000, you’ll know about it at handover. Some lenders let you buy additional miles upfront, which is usually cheaper than paying the excess charge at the end. Worth asking the question before you sign rather than hoping for the best.
HP agreements have no mileage limit at all. You can drive the car to the moon and back (within reason) because you’re paying off the full value regardless. That flexibility has a real appeal, particularly for higher-mileage drivers. If you’re doing 20,000 miles a year, HP deserves serious consideration even if the monthly payments look heavier on paper. Over a four-year term, avoiding mileage penalties on a PCP could save you well over £2,000.
What the FCA says about fair finance conduct
The Financial Conduct Authority regulates motor finance in the UK, and this matters more than many buyers realise. In 2021 the FCA banned discretionary commission arrangements, which had allowed dealers and brokers to inflate interest rates to earn bigger commissions, without the customer knowing. The ban followed an FCA review that found widespread harm to consumers. You can read the FCA’s motor finance guidance at fca.org.uk/consumers/car-finance.
In 2024 and into 2026, that issue has resurfaced significantly. The Court of Appeal ruled that undisclosed commissions on historic car finance agreements could entitle millions of UK customers to redress. The case went to the Supreme Court and the fallout is still being worked through at the time of writing. If you took out a PCP or HP deal before January 2021, it’s worth checking whether you were affected. The FCA has been pushing lenders to set aside provisions for potential compensation.
Under current FCA rules, any lender offering motor finance must be authorised, must explain the total cost of credit clearly, and must carry out affordability assessments. If you feel a finance product was mis-sold or that charges weren’t made clear at the point of sale, you have the right to complain to the lender directly and, if unresolved within eight weeks, escalate to the Financial Ombudsman Service. These aren’t just theoretical protections. Use them.
Common traps and how to sidestep them
The biggest trap on PCP is treating the optional final payment as something you’ll definitely not pay, then finding yourself emotionally attached to the car and paying it anyway without checking whether the price is fair. The GMFV is set by the finance company. It doesn’t automatically reflect what the car would actually fetch on the used market. Before paying it, get a valuation from at least two independent sources. If the market value is lower, hand the car back.
On HP, the main risk is negative equity in the early years. Because you’re paying off the full value, your outstanding balance drops slowly at first relative to the car’s depreciation. If you need to settle early or the car is written off, you might owe more than the car is worth. Gap insurance exists to cover this difference and is worth factoring into your budgeting, particularly on a brand-new car that loses significant value in the first year.
Settlement figures on both products can also surprise people. You’re entitled to a voluntary termination under the Consumer Credit Act 1974 once you’ve repaid 50% of the total amount payable. This is a legal right, not a favour the lender grants you. Know it exists.
It’s also worth thinking carefully about which type of finance suits the car you’re buying. If you’re choosing between two very different vehicles, the finance structure might actually influence that decision. Our guide on leasing versus buying in the UK covers why the monthly payment isn’t the whole story, and if you’re weighing up something like an electric car on PCP, our breakdown of the real cost of keeping a petrol car beyond 2030 is useful context for understanding residual value risk on both sides of the fuel debate.
Which is right for you
In general: if you want lower monthly payments, plan to change your car every two to three years, and drive a predictable annual mileage, PCP works well. If you want to own the car outright, drive high mileage, or prefer simplicity, HP is the cleaner option. Neither is inherently better. The trap isn’t choosing the wrong product; it’s choosing one without understanding exactly what you’re committing to.
Read the total amount payable, not just the monthly figure. Understand what happens at the end of the contract before you’re at the end of it. And if anything in the agreement feels unclear, ask the dealer to explain it in plain terms before you sign. That’s not awkward. That’s just sensible. If you’re also looking at finance on a premium vehicle, the dynamics are slightly different and it’s worth reading our Range Rover Sport vs Porsche Cayenne comparison to see how high-value residuals affect the PCP equation at the top end of the market.
Frequently Asked Questions
What is the difference between HP and PCP car finance?
HP (Hire Purchase) finances the full value of the car in equal monthly instalments, and you own it once the final payment is made. PCP (Personal Contract Purchase) only finances the difference between the purchase price and a predicted future value, leaving you with an optional lump sum payment at the end if you want to keep the car.
What happens if I go over my mileage limit on a PCP deal?
You’ll be charged an excess mileage fee, typically between 6p and 15p per additional mile, when you hand the car back. On a three-year deal with 10,000 miles of overage at 10p per mile, that’s £1,000. You can often buy extra mileage upfront at a cheaper rate, so it’s worth negotiating this before signing.
Do I have to pay the optional final payment at the end of a PCP?
No. You can hand the car back at the end of the contract with nothing more to pay, provided it’s within the agreed mileage and in reasonable condition. The optional final payment (GMFV) only applies if you choose to keep the car. If the car is worth more than the GMFV on the open market, any positive equity is yours to use.
