One of the most important decisions when taking out a mortgage is choosing between a fixed rate and a variable rate. Both have genuine advantages — the right choice depends on your circumstances and attitude to risk.

Fixed-rate mortgages

Your interest rate stays the same for an agreed period — typically 2, 3, 5 or 10 years. Advantages: complete certainty, protection if rates rise, easier to budget. Disadvantages: you won't benefit if rates fall, early repayment charges apply.

Variable-rate mortgages

Standard Variable Rate (SVR) — the lender's default rate, usually the most expensive option. Tracker mortgage — tracks the Bank of England base rate directly. Discount mortgage — set below the lender's SVR for a set period.

Which is better in 2026?

Many borrowers are opting for shorter fixed terms (2–3 years) to retain flexibility, while others prefer the security of a 5-year fix. The most popular choice in the UK remains the 2-year fixed rate — a balance of security and flexibility.

What happens when my fixed rate ends?

You'll automatically move onto your lender's SVR — almost always significantly higher. Start looking for a new deal 3–6 months before your current deal expires. You can often lock in a new rate up to 6 months ahead.
