The emails, which said “the Bank of England base rate has changed today”, were distributed ahead of the Bank’s next interest rate decision tomorrow.

According to The Herald, customers of both Halifax and Lloyds Bank were affected by the mistake.

The emails read: “we want to help you understand what this could mean for you”, and continue to explain the differences between fixed and variable rate mortgages.

The emails also highlight the support available if customers are struggling with their repayments.

A Lloyds Banking Group spokesperson apologised for any inconvenience caused.
