Frequently Asked Questions

What is a mortgage overpayment?

Can I overpay my mortgage without penalty?

Most UK mortgage lenders allow you to overpay up to 10% of your outstanding balance each year without penalty. Always check your specific mortgage terms and conditions first. Your lender’s policy will detail any overpayment limits.

Are there tax implications for overpaying my mortgage?

Generally, there are no direct tax implications for making mortgage overpayments in the UK. Overpayments reduce your debt, they are not considered income. For specific tax advice, always consult HMRC guidance or an FCA-authorised financial adviser.

Does overpaying my mortgage automatically lower my monthly payments?
