Total number of mortgage sales in the UK 2018-2022, by interest rate type
A fixed interest rate is simply a mortgage where the rate of repayment is fixed. The source defines a standard variable rate as "the rate that is the lender’s underlying variable interest rate. This rate is a basic variable rate charged to borrowers with no discounts or other special deals. It is also the rate used by the lender as a reference rate when defining a discounted variable rate product (e.g., discounted product ABC is 0.50% below the lender’s standard variable or basic rate). This is the rate that mortgage deals will often revert to after a special rate period."
Product sales data (PSD) is collected by the Financial Conduct Authority (FCA) and includes new sales (including remortgages); transfers, top-ups, alterations (such as mortgage switches with the same lender). It does not include data on transactions made through fund supermarkets and nominee accounts (such as those used in platforms) and, increments and renewals are generally not included according to the source. In the United Kingdom all home finance providers are required to submit the mortgage PSD.
