What is the Bank of England Base Rate?
The Base Rate is the official interest rate set by the Bank of England. When the Bank of England decides to change the official interest rate, this can have an effect on your mortgage payments.
What will happen to my mortgage if the rate changes?
The impact of any change will depend on the type of mortgage you have, the amount you’ve borrowed and how long you’ve taken it out for. If any part of your mortgage is on one of our variable rates and your rate changes following a change to the Bank of England Base Rate, your payment may go up or down. If this happens, we’ll write to you confirming your new payment.
If you’re worried about how a change in interest rate might affect you, the first thing to do is check what type of mortgage you’re on:
A tracker mortgage is a variable rate mortgage. The difference between these and other variable rate mortgages is that they follow, or track, the movements of another rate, most commonly the Bank of England Base Rate. If your mortgage is affected by the rate change, we will write to confirm your new payment. Any change in interest rates will usually take effect from the first of the month following the Bank of England’s announcement.
Currently on a Fixed Rate Mortgage?
If you’re on a fixed-rate mortgage your payments will stay the same for the fixed-rate period, as the rate you’re paying does not move in line with the Bank of England Base Rate. The benefit of a fixed rate is that it removes the uncertainty of the rate going up; of course the Bank of England base rate could go down during the fixed rate period

Do I need to take any action?
If you have a variable rate mortgage which is impacted by the rate change, we’ll write to you to let you know what your new monthly payment will be and what action you need to take. The letter will arrive before the change takes effect, usually on the first day of the month following the announcement of the change.
Payments by standing order
If you pay your mortgage by standing order, you’ll need to contact your bank to amend the amount from the date shown on your rate change letter. Unfortunately this can’t be done by us on your behalf, so you may find it easier to pay by Direct Debit instead.
Payments by Direct Debit
If you pay your mortgage by Direct Debit there’s no need to take any action. The new amount will be collected as usual.
Payments by cash or cheque
If you pay your mortgage by cash or cheque, simply adjust the amount(s) that you send to us each month.
What if I’m on an instalment or payment break?
If you’re on an agreed Instalment Break or Payment Break, the new interest rate will be applied to your account from the date shown on your rate change letter. Once your break comes to an end, the revised payment amounts will apply.
Worried about making your repayments?
If your payments have increased and you feel that you’re unable to meet them, please contact our team on 0345 835 3374 , where full support will be available.
Base Rate Change Letters
We are mailing our mortgage customers to tell them how the Bank of England base rate change affects their monthly payments.
If you currently make an overpayment, we'll continue to collect the same extra amount as we do currently on top of your new monthly payment.
If you would like to start, change or cancel a regular overpayment, you can do this by using the form below. You'll need your mortgage account number, which can be found on your mortgage statement or other mortgage related letters.
We have changed some or all of our variable mortgage interest rates because there has been a change to our cost of lending or we know that our cost of lending is about to change. There are a number of reasons why our cost of lending can change and they include a change in Bank of England base lending rate or a change to laws and regulations that impact our costs.
If you have a tracker rate, the change will be because the rate automatically follows the Bank of England base lending rate.
Simply adjust the amount you send us each month to the new total monthly payment shown above. Please remember, if you are sending in a payment by cheque, make sure the payee is shown as 'TSB Bank plc', followed by either your name or your mortgage account number.
You do not need to make any payments during the period of your 'Payment Holiday'. However the new interest rate will be applied to your account from the date shown above. Once the arrangement comes to an end, the revised payment shown will apply.
Lenders are required to write to you about all payment amount changes on parts of your mortgage (sub-accounts) that are regulated by the Consumer Credit Act 1974 (CCA). Lenders must provide separate notification for each account to everyone named on the mortgage.
Therefore, if one or more of your sub-accounts are CCA regulated, you will receive a letter for each of the relevant accounts
There are a number of reasons why your payment may have gone up even though the base rate has gone down
When rates change from the 1st of the month, then we deduct your next monthly payment – at the new interest rate – from the mortgage balance used to calculate your new monthly payment. However, when our rates change on a day other than the 1st of the month, then we can’t always do this. This means the balance we use to calculate your new monthly payment may be a little higher than expected and so the revised monthly payment a little higher as well. But rest assured, we’re still using the new interest rate to calculate your new monthly payment
If you are on a repayment mortgage, and there’s not long to go until your mortgage ends, your monthly payments may have increased to make sure you pay off everything you owe at the end of your mortgage.
You may have or recently had a payment holiday and your monthly payments have increased to make sure you remain on track to pay off everything you owe by the end of your mortgage term. If you’re currently on a payment holiday you don’t need to take any action.
