The one-line differences
• HP — fixed monthly instalments over 24–60 months. Ownership transfers on the final payment. Best for drivers who keep cars long term.
• PCP — lower monthlies with a big optional balloon payment at the end. Mileage cap applies. Best for drivers who change car every 2–4 years.
• Personal loan — unsecured cash used to buy the car outright. You own it from day one. Best when rates are sharp and you want no restrictions.
A worked example: £18,000 car, 48 months
To make this concrete, imagine a £18,000 car with a £2,000 deposit, taken over 48 months at a 12.9% representative APR. In real life the APR would vary slightly by product; we're holding it flat here to isolate the structural differences.
HP: Monthly payment around £428. Total interest across the term about £4,540. Own the car outright at the end — no further payments.
PCP (with a £7,500 balloon): Monthly payment around £218. Total interest across the term about £4,780. To keep the car at the end you'd pay the £7,500 balloon; if you hand it back you walk away.
Personal loan for the full £18,000 (no dealer deposit): Monthly payment around £479. Total interest about £5,100. You own the car from day one.
PCP wins the headline monthly by a mile. HP wins the total-cost-if-you-keep-the-car race. The personal loan gives you maximum flexibility — you can sell the car whenever — but you pay for that flexibility.
Mileage, wear and end-of-term
PCP is the only product with a formal annual mileage cap. Setting it correctly at the start is critical: at 5–25p per excess mile, misjudging by 3,000 miles a year for four years can add £600–£3,000 to your bill.
PCP also runs a fair-wear-and-tear inspection at return. Small kerbs on alloys or a light scratch is fine; anything beyond the BVRLA fair-wear guide is chargeable.
HP has neither cap nor inspection. Personal loans obviously don't either — the car is entirely yours.
Ownership and flexibility
If you plan to modify, sell or scrap the car during the finance term, only a personal loan gives you full control. HP and PCP both restrict changes without lender permission because the car secures the debt.
That said, PCP's real superpower is the end-of-term “three ways out” option: pay the balloon and keep the car, hand it back and walk away, or roll any equity into a new PCP on a newer car. That flexibility is genuinely valuable if you like a new car every few years.
The refinance angle
Refinancing at the end of a PCP is now common: instead of paying the balloon in one hit, drivers refinance it onto a 24–48 month HP agreement, spreading the balloon out and keeping the car. This effectively turns the last chapter of a PCP into a mini-HP — useful if the car has held its value.
HP itself is refinanced less often mid-term because the car acts as collateral for the current lender. Personal loans are the easiest to refinance because they're unsecured.
Reader personas
• You keep cars for 5+ years and drive 15,000+ miles a year. HP is almost always the winner.
• You change car every 2–4 years and drive 8,000–12,000 miles. PCP will typically feel best, but always run the total-cost check.
• You have excellent credit and want zero restrictions. A personal loan can occasionally beat HP on rate — worth comparing.
• You're rebuilding credit. HP is the pragmatic winner — secured lending is more forgiving and on-time payments rebuild your file.
