What does a £125,000 mortgage cost per month?
At 5.25% APR over a 15-year term, the monthly repayment on a £125,000 mortgage is about £1,004.85. Over the life of the loan you'd repay £180,872.49 in total — of which £55,872.49 is interest.

How to lower the repayment
- Increase your deposit to reduce the loan amount.
- Improve your credit score before applying — even a 0.25% rate cut saves thousands.
- Compare whole-of-market brokers, not just your high-street bank.
- Consider overpayments — most UK lenders allow 10% per year fee-free.
