Rate change information - Siberite

Rate change information

We’ll always write to you at least four working days before your interest rate changes. The letter we send you will tell you about your new rate and when your monthly payment will change, and you won’t need to do anything until you receive our letter.

There’s more information below about what happens when your interest rate changes.

Rate rise calculator

See how an interest rate rise could affect your monthly mortgage payments.

Rates have changed several times in recent years, so planning now can help you prepare for any future increases in your payments.

Using this tool

You’ll need to know your outstanding balance, type of mortgage (interest only or repayment), current interest rate and how long is left on your mortgage.

If your mortgage is made up of multiple sub-accounts you can enter details for each part separately.

Understanding the results

Our calculator shows the increase in monthly payments, for a repayment or interest only mortgage, at a range of different interest rates.

The results you’ll see are based on the information you have entered for your current balance, interest rate and remaining term.

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 mortgage payments after an interest rate increase may differ slightly to the figures shown in the calculator.

This means the results should only be used as a guide.

When is an interest rate change triggered?

The events that could trigger a change in your interest rate depend upon the type of rate that applies to your mortgage.

The London Interbank Offered Rate (LIBOR) is no longer being published. 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, your interest rate will continue to be reviewed 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 has a Product Variable Rate (PVR) or tracks Bank of England base rate (BBR), your rate will usually change at the start of the month after the Bank of England announces a change in BBR.

We won’t be able to tell you what your new monthly payment will be if you call us immediately after a change in BBR has been announced. This is because the rate change needs to be applied to your account and your recalculated payment updated.

You’ll be able to check any change in your monthly payment by signing in to Self-Serve. After the change has been applied to your account there’ll be a message about your new payment amount on the account summary screen. Find out more here.

We’ll also write to you before any change in your monthly payment takes effect.

The most recent change in BBR to its current 5.25% was announced on 3 August 2023. We wrote to you in late August to confirm your new rate and when your monthly payment would change. That rate will continue to apply until after any further change to BBR is announced.

The SVR is set in response to trends in the UK mortgage market. The 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 the SVR is regularly reviewed, there aren’t any fixed dates on which it will change. 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 the rate change needs to be applied to your account and your recalculated payment updated.

You can see your current interest rate, monthly payment amount and details of future changes by signing in to Self-Serve. After the change has been applied to your account there’ll be a message about your new payment amount on the account summary screen. Find out more here.
