Royal Bank of Scotland and NatWest are the latest lenders to announce passing on the base rate increase to mortgage holders in December.
Customers on base rate linked products will see the rate increase by 0.25%, while the standard variable rate is being increased by 0.24% to 3.99% for all residential mortgages.
An RBS spokesman said: “We are writing to all of our mortgage customers on our standard variable rate to advise that their rate will change on 1 December.
“We will also increase rates on the majority of our savings accounts.
“We offer a range of fixed rate mortgages which could benefit customers as well as a free financial health check, which could help customers adjust to a change in their monthly payments.
“Customers can also find information on our website to help them understand their choices and ways of managing their money.”
