Fixed Rate vs Variable Rate Mortgages: Which Is Right for You?

One of the most frequent questions I'm asked as a mortgage broker is: should I fix my rate, or go variable? There's no single right answer — it depends on your circumstances, your appetite for risk, and your view on where interest rates are heading.

Here's a clear breakdown of both options.

Fixed-rate mortgages

With a fixed-rate mortgage, your interest rate — and therefore your monthly payments — stay the same for an agreed period. Common fixed terms are 2, 3, 5, and 10 years.

Advantages:

• Certainty — you know exactly what you'll pay each month
• Budgeting — ideal if you have a tight budget or prefer predictability
• Protection — if the Bank of England raises rates, you're unaffected during the fixed term

Disadvantages:

• Less flexibility — leaving the deal early usually incurs an Early Repayment Charge (ERC)
• Miss out if rates fall — if rates drop, you'll still pay the higher fixed rate
• Slightly higher starting rate — fixed rates typically come with a small premium over variable products

How long should I fix for?

This is where personal preference and market conditions come in. As a general guide:

• 2-year fix — more flexibility to switch, useful if you think rates will fall soon
• 5-year fix — popular choice; provides medium-term stability, and rates are often competitive
• 10-year fix — best for those wanting maximum certainty, e.g. nearing retirement on a fixed income

Variable-rate mortgages

Variable rates move up and down — either in line with the Bank of England base rate or at the lender's discretion. The main types are:

Tracker mortgages — set at a defined margin above the Bank of England base rate. If the base rate moves, your rate moves with it.

Discount mortgages — a fixed percentage below the lender's Standard Variable Rate (SVR).

Standard Variable Rate (SVR) — the lender's default rate, usually applied when a fixed or tracker deal ends.

Advantages:

• Potentially lower initial rate — especially tracker mortgages in a falling rate environment
• Flexibility — many tracker products have no early repayment charges
• Benefit if rates fall — your payments reduce automatically

Disadvantages:

• Uncertainty — your monthly payment can increase if the base rate rises
• Harder to budget — especially on a tight income

Which is right for you?

In practice, most borrowers in the UK currently choose fixed-rate mortgages — particularly 5-year fixes. Here's a simple framework to help you decide:

The "right" choice depends on your individual circumstances — which is exactly why speaking to a broker is so valuable. I can run the numbers, explain the current market, and recommend the product that truly fits your situation.
