Remortgage guides (UK)
Use these guides to understand the process, avoid common fee traps, and time your switch properly. If you only do one thing, compare total cost (payments + fees + any ERC) over the period you’ll keep the deal.
What is a remortgage?
The clear definition, the two ways to switch, why people do it, common risks, and a simple decision checklist.
Remortgage process (timeline)
A practical step-by-step timeline with realistic timeframes and the most common causes of delay.
Remortgage fees explained
Product fees, valuations, legal work, broker fees, and what matters most when comparing total cost.
Early repayment charges (ERC)
How ERCs work, when they apply, typical percentages, and how to time your remortgage to avoid paying them.
Quick start (3 steps)
- Check your ERC and end date so you don’t complete too early.
- Calculate your LTV to understand which rate band you’re likely in.
- Compare total cost for the period you’ll keep the new deal, not just the headline rate.
