Use our rate change calculator to get an idea of how much your monthly mortgage payment might change.
You can find your current mortgage details in your most recent annual mortgage statement.
If you have a fixed rate mortgage, any change to the Bank of England base rate will not affect the fixed interest rate during the fixed rate period.
Where your mortgage is made up of a number of variable rate sub-accounts or parts, you'll need to complete separate calculations for each one.
If your mortgage is affected by a rate change, we will always write to you, to let you know your new monthly payment ahead of it being taken.
