Find out more about the base rate
Find out what affects it, how it affects interest rates and when the next announcement will take place at the Bank of England website.
The official base rate is set by the Bank of England and affects the interest rates offered by Banks, Building Societies and other financial institutions. Through changing the rate, the Bank of England seeks to meet the target set by the Government to keep inflation low and stable, as well as influencing overall borrowing in the economy.
The Bank of England base rate can go up or down and is announced at the Monetary Policy Committee (MPC).
Changes to the base rate could affect interest rates and payments on any savings or mortgages you hold with us.
