Introduction
Fixed-rate mortgages remain the most popular mortgage choice in the UK, especially during periods of economic uncertainty. In 2026, borrowers are increasingly choosing fixed deals to protect themselves from interest rate fluctuations.
This guide explains how fixed-rate mortgages work, compares 2, 5, and 10-year deals, and shows how to choose the best option.

However, you will not benefit if rates fall during your fixed term.
