Compare Fixed vs Variable Rate Mortgages

You have been told to consider both fixed and variable, with no explanation of what the choice does to your real life. This compares them where it counts: how certain your monthly payment is, what happens to each when the Bank of England moves rates, and which suits how much uncertainty you can stomach. For first-time buyers facing a decision dressed up in jargon.

**Compare across four practical dimensions:**
1. Monthly payment certainty: what changes and when under each type
2. What happens when the Bank of England base rate moves
3. Early repayment: the cost of leaving or overpaying under each type
4. Who each type suits based on risk tolerance and likely life changes
