Remortgaging at the right time can save you thousands of pounds. This guide explains when to remortgage, how to compare deals effectively, what fees to expect, and the step-by-step remortgaging process.

When Should You Remortgage?

• When your fixed-rate deal is about to expire (start comparing 3–6 months before)
• When market rates have fallen significantly since you took out your current deal
• When your property value has risen, improving your LTV band and access to better rates
• When you want to release equity for home improvements or other purposes
• When you want to consolidate other debts (seek independent financial advice first)
