Bank of England Base Rate change

What happens if the Base Rate goes up or down?


Supporting you when interest rates change

The Bank of England Base Rate has been consistently low for a number of years. But if it changes, this’ll have an impact on your mortgage payments if you have a mortgage linked to this rate.

Current rates:

The Bank of England Base Rate is 0.10%.

(Rate applies to existing customers from 18 April 2020)

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 (unless you’re on the Annual Instalment Review scheme - find out more below).

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:

Currently on Standard Variable Rate (SVR)?

Currently on Homeowner Variable Rate (HVR)?

Find out more about our Homeowner Variable Rate.

Currently on Buy-to-Let Variable Rate (BVR)?

Currently on a Tracker Mortgage?

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 part of the Annual Instalment Review (AIR) scheme?

If you are in the Annual Instalment Review scheme, where your monthly mortgage payment changes just once each year, the overall effect of any rate changes during the year will be taken into account at the next annual review. We’ll let you know your new payment for the next 12 months when we send you your annual mortgage statement.

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?

Frequently Asked Questions

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

If the amount you are required to pay has changed please contact the relevant Benefits Agency or the Payment Protection policy provider direct to notify them of the change.

This may be for one or more of the following reasons:

  • You have recently taken a 'Payment Holiday' in which case the balance of your mortgage will have increased.
  • Your account may be in arrears.
  • Your chosen payment date may be on a day in the month other than the 1st. In this case, the mortgage balance used to calculate your new payment will not take into account your next mortgage payment.
  • You may have transferred funds, or had a refund made from a sub-account, which would affect the mortgage balance used to calculate the new monthly figure.

A fee may have been added, for example a conversion or interest certificate fee, to your Fees and Charges sub-account (99).
