Around 1.1 million households will see a mortgage hike before a potential general election in November. According to research by the Liberal Democrats, which used Financial Conduct Authority (FCA) data, 1.1 million fixed rate terms will end between February and October, and of these, 700,000 fixed rate mortgages will expire between May and October. A typical homeowner will have seen their monthly mortgage interest payments go up by £240, equivalent to a 39% rise.
