Rate change information
On Thursday 18 December, the Bank of England base rate (Bank Rate) was reduced from 4.00% to 3.75%.
As a result, the interest rate on all our mortgages that track Bank Rate will reduce by 0.25% from 1 January 2026.
We’re also reducing our Standard Variable Rate (SVR) by 0.25% from 1 January 2026.
If your interest rate is changing, we’ll write to you before your rate changes to tell you your new rate and monthly payment amount. You don’t need to do anything until you receive our letter.
Quickly estimate your new monthly payment
You can check the effect of a rate reduction now using our new rate change calculator.
See how an interest rate change could affect your monthly mortgage payments, and the total amount you’ll pay over your remaining term.
Using this tool
You’ll need to know the outstanding balance, repayment type (interest only, part & part or capital and interest), current interest rate and remaining term of your mortgage.
Find out how to see up to date information about your mortgage.
If your mortgage has sub-accounts with different interest rates, repayment types or outstanding terms, you’ll need to enter details for each sub-account separately into the calculator.
Understanding the results
Our calculator shows how your monthly payments and the total amount payable over your remaining term could alter if your interest rate changes.
The results you’ll see are based on the information you enter for your current balance, interest rate and remaining term – plus the new interest rate you want to compare.
Our calculator uses a simple method to determine the amount of interest you’ll pay as part of your monthly payment, by dividing the total amount of interest you’ll pay over a full year into 12 equal monthly amounts.
Since interest on your mortgage may be calculated differently (such as on a daily basis), then the actual change in your monthly payments and total amount payable after an interest rate change may differ slightly to the figures shown in the calculator.
Our calculator also makes several other assumptions about your mortgage, including:
- You make your standard monthly payment every month over the full remaining term.
- There is no further change to your interest rate over the full remaining term.
- There are no fees or charges added to the balance you owe.
- There are no other changes to your mortgage which would result in a recalculation of your monthly payment (e.g. changes to your remaining term or the repayment type of your mortgage).
This means the results should only be used as a guide.
There’s more information below about what happens when your interest rate changes.
When is an interest rate change triggered?
The events that trigger a change in your interest rate depend upon the type of variable interest rate that you have.
The published London Interbank Offered Rate (LIBOR) is being wound down. You were written to in 2021 to explain how your account would be affected, and you can find more information about the end of LIBOR on our website here.
The end of LIBOR means that the reference rate used to set your interest rate has changed or will change later this year. However, we’ll continue to review your interest rate once every three months.
We’ll always write to you before any change in the interest rate that applies to your mortgage, or your monthly payment takes effect.
If your interest rate tracks the Bank of England base rate (the Bank Rate), your rate will usually change at the start of the month after the Bank of England announces a change in the Bank Rate.
The most recent change in the Bank Rate to its current 3.75% was announced on 18 December 2025. If your interest rate is changing, we’ll write to you later in December to confirm your new rate and when your new payment will apply.
That rate will continue to apply until after any further change to the Bank Rate is announced.
If your interest rate and monthly payment are due to change at the start of the next month, you’ll find details of your new rate, payment amount and the date when this will apply in our online Self-Serve system.
This will be available to view after we have processed the rate change on your account. We’ll do this as soon as possible, although it can sometimes take several days.
If you call us, we won’t be able to confirm your new rate and payment until it’s also showing in Self-Serve. So, if it’s not there, please check back later.

We’re reducing our SVR by 0.25% from 1 January 2026.
If your interest rate is changing, we’ll write to you later in December to confirm your new rate and when your new payment will apply.
We set our SVR in response to trends in the UK mortgage market. Our SVR isn’t directly linked to any external reference rate, this means that it doesn’t automatically change if for example, the Bank of England changes Base Rate. Although we keep our SVR under regular review there aren’t any fixed dates on which we decide to change it.
We’ll always write to you before any change in your rate takes effect. If your account is linked to SVR, your rate will usually change at the start of the month after the change to the SVR is announced.
We won’t be able to tell you what your new monthly payment will be if you call us immediately after a change in SVR has been announced. This is because we need to apply the rate change to your account and to calculate your updated payment.
You can see your current interest rate, monthly payment amount and details of future changes by signing in to Self-Serve. After we’ve applied an SVR change to your account there’ll be a message about your new interest rate, monthly payment amount and the date when this will apply on the account summary screen.

More information about your account and interest rate changes
Please read the answers to the questions below before you call us with a question about your account.
Unfortunately, we’re closed to new business and unable to offer any new deals to customers.
There’s more information about remortgaging with another lender on our Find a better mortgage deal page.
Unfortunately, we can’t freeze your interest rate. However, there may be options available to you if you’re struggling to afford your monthly payments. If you’re worried about making your payments, please take a look at the information about how we may be able to help on our Payment difficulties page. Simply getting in touch with us won’t affect your credit file.
Your monthly payment is calculated based on your outstanding balance and the remaining term of your mortgage, at the point when a new interest rate is set.
The payment will vary according to the repayment basis of your mortgage.
If you have a capital and interest (repayment mortgage), your monthly payments cover the interest charged each month and also pay off some of the balance that you owe. This means that providing you make your monthly payments in full and on time, your mortgage will be fully repaid at the end of its term.
If you have an interest only mortgage, your monthly payments only cover the interest charged on the balance you owe. Your payments don’t reduce the total amount you owe over time, so when your mortgage reaches the end of its term, you’ll need to repay this to us as a lump sum.
If you have a part & part mortgage, a set portion of your mortgage is on a repayment basis and another set portion is on interest only. Here, your monthly payments will cover the interest charged on the whole amount you owe, but you’ll also be repaying part of that total balance each month. So unlike a full repayment mortgage, this means there will still be a lump sum to pay at the end of the mortgage term.
Find out what type of mortgage you have
It’s important you’re fully aware of the type of mortgage you have, so you can plan ahead. If you’re unsure, you can easily find this information using Self-Serve, our secure online mortgage service, which is available 24 hours a day, 7 days a week. See our website section about finding your account information.
You can also see your latest mortgage statement or check your latest mortgage offer documents. Alternatively, if you need further support, please contact us.
The impact of an interest rate change on your monthly payments will depend on several factors, such as the type of mortgage you have (interest only, capital and interest or part & part), your current balance and remaining term.
There are also other factors that can affect the recalculation of your monthly payment, for example if you have:
- made regular overpayments on your account;
- incurred any fees or charges that have been added to your balance;
- taken a payment holiday;
- not paid ground rent/service charges and we’ve paid these on your behalf;
- missed any payments or made reduced payments for any reason.
The impact of these factors on the recalculation of your monthly payment following a rate change may be greater if you only have a short remaining term.
Because of this, the exact change in your monthly payments following a rate change may be different to what you expect.
If you’re worried about making your monthly mortgage payments now or in the future there’s more information about how we may be able to help you on our Payment Difficulties page.

If you’re paying an extra amount on top of your normal monthly payment as part of an agreement to clear or reduce your arrears, it’s important to continue paying that extra amount. But if your monthly payment has increased and you’re struggling to keep up the arrangement we’ll need to reassess your situation.
There’s more information on our Payment difficulties page about how you can start that process by going online to provide us with updated income and expenditure details. You can also call us. You may find it useful to have your bank statements, wage slips and utility bills to hand.
When you’re making regular monthly overpayments, it’s a good idea to check you’re happy with the amount you’re overpaying after an interest rate change. Depending upon how your overpayment is set up and whether your normal monthly payment has gone up or down, you may want to check and adjust the amount you’re overpaying. There’s more information about making regular monthly overpayments on our Overpayments page.
If you make your monthly payments by Direct Debit you don’t need to take any action, we’ll collect the new payment amount when this is due.
