The simple difference between HP and PCP
Hire Purchase, or HP, is usually the easier structure to understand. You pay a deposit, make monthly payments, and normally own the car after the final payment and any option-to-purchase fee.
Personal Contract Purchase, or PCP, usually has lower monthly payments because a chunk of the car value is left until the end as an optional final payment, often called the balloon payment or guaranteed minimum future value.
That lower monthly PCP payment can be useful, but it means the end of the agreement matters more. You normally choose whether to hand the car back, part-exchange into another deal, or pay the final balloon payment to own it.
