Bank of England base rate raised by 0.25% to 4.25%: How will it impact your finances?

The Bank of England (BoE) announced the latest rise to the base rate, increasing it by 0.25%, taking it from 4.25% to 4.50%. It is the 12th consecutive base rate rise since December 2021 and it is now at the highest level since the height of the financial crisis in 2008. In this article, we reveal the impact the latest base rate rise will have on both savers and borrowers. We also provide some resources and tools to help those who are looking to remortgage soon.

What is the Bank of England base rate?

The Bank of England base rate is the rate that the Bank of England charges banks, building societies and other lenders when they borrow money. A rise to the Bank of England base rate causes a knock-on effect, meaning banks and other lenders need to raise the interest rate that they charge borrowers, to ensure they continue to make a profit. Conversely, savers are likely to see savings rates increase across the market, although this isn't guaranteed for every lender and the rate offered will often be far lower than the rate charged to borrowers, again, ensuring the lender makes a profit.

Why has the Bank of England base rate increased again?

The Monetary Policy Committee (MPC) voted to raise the Bank of England base rate by 0.25%. The annual rate of inflation remains stubbornly high at 10.1% for March 2023, down slightly from 10.4% in February, but it is still well above the official target rate of 2%. It is hoped that the latest interest rate rise will help cool inflation with the latest forecasts predicting inflation will fall to around 7% by mid-summer and around 5.2% towards the end of 2023.

However, some economists are predicting there may be one or two more rate rises still to come before the Bank of England pauses. A lot will depend on UK inflation data in the coming months as well as the general health and stability of the banking sector and UK economy.

How does the BoE interest rate rise affect you if you have a mortgage?

Fixed-rate mortgage customers

Roughly 75% of mortgage holders are on a fixed-rate mortgage deal protecting them, for the time being at least, from the latest interest rate rise. If your fixed-rate deal is coming to an end in the next 6 months then you may wish to read our article 'Remortgaging in 2023 – is now the right time to fix & for how long?'.

Those on a fixed-rate mortgage deal that is coming to an end (even if it is in more than 6 month's time) should consider the impact that the latest interest rate rise will have on their monthly mortgage repayments when they remortgage and budget accordingly. As a rough guide, the 0.25% rise will mean the monthly mortgage repayments will rise by around £13 per month for every £100,000 you owe, based on a 25-year mortgage term. However, the figures are only based on the latest base rate rise, so if your current fixed-rate deal was in place before December 2021, you will need to include the cost of all of the rate rises combined. This works out at an increase of roughly £229 per month, per £100,000 borrowed, based on a 25-year mortgage term.

Variable rate or tracker mortgage customers

Those with tracker or variable rate mortgages are likely to see their mortgage payments increase in line with the latest Bank of England base rate announcement, however, lenders often take time to implement the increase, so exactly when you will feel the increase will depend on your lender. You can work out what the impact will be on your mortgage payments by using our interest rate rise calculator. You'll need to know your initial mortgage term, the initial mortgage amount borrowed at the start of the deal and your current mortgage rate.

Anyone worried about the impact that the latest base rate rise will have on their finances should speak with an independent mortgage adviser* as they can easily explain the likely impact on your finances as well as the best way to remortgage. They will be able to weigh up your options and compare what mortgage rates and deals are available to you. Always check to see if there are any Early Repayment Charges (ERC) when remortgaging and check to see how long is left on your current deal. Alternatively, you can take a look for yourself by using our mortgage best buy calculator.

How does the BoE interest rate rise affect you if you have credit cards, loans or overdrafts?

Credit cards

It is likely that your credit card provider will increase the Annual Percentage Rates (APR) on your credit card. However, if you have an existing credit card with an agreed interest-free period or promotional interest rate you won't notice any immediate impact from the Bank of England rate rise. However, if your promotional period is due to end, or you are applying for a new credit card in the future, you will likely notice that the APR increases. One way to avoid a rise in interest on your credit card is to complete a balance transfer, by transferring your existing credit card balance to a 0% balance transfer credit card. To ensure you pay no interest on your repayments, the balance needs to be repaid within the promotional interest-free period. Be aware that most (not all) balance transfer credit cards charge a balance transfer fee, usually between 2% and 5, and of course you will be credit checked during the application process. Find out more in our article, 'Best 0% balance transfer credit cards'.


If you already have a loan in place and it has a fixed interest rate then you are unlikely to be affected by the latest base rate rise. Those looking for a new loan are likely to see higher APR deals entering the market.


The interest rate charged on your overdraft could be impacted by the latest rise in the Bank of England's base rate and so your overdraft rate could go up. You should receive advanced notification from your Bank or Building Society if this is the case, giving you time to consider your options.

How does the BoE interest rate rise affect you if you have savings?

Savings rates are likely to go up as a result of the latest Bank of England base rate rise, however, it is up to the individual bank or building society as to when/if they increase their rates. Some will take weeks or even months to increase rates following a Monetary Policy Committee announcement and others may not increase rates at all, as they are under no obligation to do so. If you are looking for the best savings rates then you should always shop around for the best deal. Check out the best savings rates using our Savings Best Buy tables.
