Fixed vs Variable Mortgages: How to Choose the Right Deal for Your Circumstances
Choosing between a fixed and variable rate mortgage is one of the most important financial decisions you’ll make as a homeowner. The truth is, there’s no universally “best” option—what works brilliantly for your neighbour might be completely wrong for your circumstances.
This guide explains the key mortgage types available and helps you decide which approach suits your situation.
Understanding the Fundamental Difference
Fixed-rate mortgages lock your interest rate for a set period—typically two, three, five, or even ten years. Your monthly payments stay identical regardless of market changes. When the fixed period ends, you’ll move onto your lender’s standard variable rate unless you remortgage.
Variable-rate mortgages fluctuate based on various factors, meaning your monthly payments can go up or down throughout your mortgage term.
Types of Variable Mortgages Explained
Tracker mortgages follow the Bank of England base rate at a set margin above it. If the base rate is 4.5% and your tracker is “base rate plus 1%”, you pay 5.5%. These offer complete transparency but no protection against rate increases.
Discount variable mortgages offer a discount off the lender’s standard variable rate (SVR) for a set period. However, lenders can change their SVR at any time, giving you less certainty than tracker deals.
Standard variable rate (SVR) is what you revert to when any deal ends. It’s typically the lender’s highest rate—most people find themselves on it by default rather than actively choosing it.
Fixed-Rate Mortgages: Pros and Cons
Fixed rates offer complete payment certainty, making budgeting straightforward and protecting you from rate increases. This peace of mind is particularly valuable if you’re stretching affordability or have limited financial cushion.
However, you won’t benefit if rates fall during your fixed period. Early repayment charges (ERCs) can be substantial if you need to exit early, creating potential issues if you move house and your mortgage isn’t portable.
Variable-Rate Mortgages: Pros and Cons
Variable rates often start lower than equivalent fixed rates, potentially saving money if rates remain stable or fall. Tracker mortgages offer transparency—you’re not at the mercy of your lender’s SVR decisions.
The downside is uncertainty. Payments could increase significantly, which can strain budgets and create stress if rates rise sharply.
Two-Year vs Five-Year Fixed Deals
Two-year fixed deals typically offer the lowest rates but require remortgaging more frequently. This suits those valuing flexibility—perhaps planning to move or expecting income changes. However, you face arrangement fees every two years.
Five-year fixed deals provide extended security and avoid frequent remortgaging hassle. Rates are usually slightly higher, but you’re protected longer. The trade-off is reduced flexibility with ERCs typically applying throughout.
Decision Framework: What Suits You?
Consider these key factors:
Risk tolerance: If payment uncertainty worries you, fixed rates provide peace of mind. Comfortable with fluctuation and have financial buffer? Variable rates might save money.
Income stability: Variable income or commission-based earnings often pair better with fixed rates, ensuring mortgage payments remain manageable during leaner months.
Future plans: Planning to move within two years? Shorter fixes offer flexibility. Settling long-term? Five-year fixes might suit better.
Affordability margins: Borrowing close to maximum affordability? Fixed rates protect against unmanageable increases. Comfortable headroom? You might tolerate variable fluctuations.
Beyond the Rate: Important Features
Look at early repayment charges if circumstances might change. Portability allows transferring your mortgage to a new property without penalties. Overpayment allowances let you reduce your balance faster—most deals allow 10% annually without penalty.

Frequently Asked Questions
Should I fix my mortgage rate right now? This depends on your personal circumstances. If you need payment certainty and couldn’t comfortably manage increases, fixing provides security. If you have financial flexibility, variable options might suit better.
What’s better: a 2-year or 5-year fixed mortgage? Two-year fixes offer lower rates and flexibility but require remortgaging more frequently. Five-year fixes provide extended security at slightly higher rates. Your choice depends on whether you prioritise flexibility or long-term certainty.
How does a tracker mortgage work? Trackers follow the Bank of England base rate at a set margin above it. When the base rate changes, your rate changes automatically by the same amount—offering transparency but no protection from increases.
Can I switch from a variable to a fixed rate mortgage? Yes, though if you’re mid-deal, early repayment charges might apply. If your deal has ended and you’re on the SVR, you can switch without penalties.
