You would think that your repayments should automatically reduce when the rate drops. It actually depends on which lender you are with. Below is a compiled list of answers from each lender.

Below is a list of what happens depending on your lender.
If you’re making Principal & Interest repayments on your loan and your lender announces an interest rate drop, nothing generally happens to your loan repayments – for a while at least anyway. With most lenders, unless you ask for a change to your repayments, your minimum monthly repayment stays the same but since you’re now charged less interest, each repayment consists of a higher proportion of principal.
In all instances, your lender will notify you of any change to your interest rate change, changes to you minimum repayments and if action you need to take to change your direct debit repayments.
