UK mortgage repayment guide

Repayment vs interest-only

Repayment mortgages pay down capital and interest each month so the loan is cleared by term end. Interest-only mortgages pay only interest — you need a separate plan to repay the capital.

Most residential buyers use repayment. Interest-only is more common for buy-to-let with documented repayment vehicles.

UK-specific considerations

Deposit requirements typically start around 5–10% for residential purchases, with better rates at 15–25% deposit. Loan-to-value (LTV) bands affect the rate you are offered.
