Choosing the wrong mortgage type can make monthly payments harder to manage.
When you’re looking to buy a home or invest in property in the UK, one of the biggest decisions you’ll make is choosing the right mortgage type. Two popular options are fixed-rate mortgages and tracker mortgages. But what exactly do these terms mean, and how do they work?
In this guide, we’ll break down the key differences between fixed and tracker mortgages, explain the pros and cons, and give simple UK examples to help you understand which option could be more suitable for your circumstances.
This guide covers:
- What a fixed-rate mortgage is
- What a tracker mortgage is
- The main differences between fixed and tracker mortgages
- Pros and cons of each mortgage type
- Fixed vs tracker mortgages for buy-to-let buyers
- Other variable mortgage options
- When to speak with a mortgage adviser
What Is a Fixed-Rate Mortgage?
A fixed-rate mortgage is a type of home loan where the interest rate stays the same for an agreed period. This is usually between 2 and 10 years, depending on the mortgage product and lender.
This means your monthly mortgage repayments will not change during the fixed period, even if interest rates or the Bank of England base rate change.
For many UK buyers, this is one of the main reasons fixed-rate mortgages are popular. They offer payment certainty and make it easier to budget.
When Can a Fixed-Rate Mortgage Be Useful?
A fixed-rate mortgage can be useful if you want stability and predictable monthly payments.
Many borrowers like fixed-rate mortgages because they know exactly how much they need to pay each month during the fixed term. This can help reduce uncertainty and make household budgeting easier.
Example:
Sarah and Tom are first-time buyers in Birmingham. They choose a 5-year fixed-rate mortgage at 3%.
This means their monthly repayments will stay the same for five years, even if the Bank of England raises interest rates during that time. This helps them plan their finances with more confidence.
Pros of Fixed-Rate Mortgages
Fixed-rate mortgages can offer several benefits, especially for buyers who want financial certainty.
- Predictable monthly mortgage payments
- Protection from interest rate rises during the fixed term
- Easier budgeting for households
- Useful for first-time buyers who want repayment stability
- Can provide peace of mind during uncertain market conditions
Cons of Fixed-Rate Mortgages
Fixed-rate mortgages may not suit everyone. There are some points to consider before choosing this type of mortgage.
- Initial rates may be higher than some variable mortgage options
- Less flexibility if interest rates fall
- Early repayment charges may apply if you leave the deal early
- Overpayment limits may apply during the fixed period
- You may need to remortgage when the fixed term ends
What Is a Tracker Mortgage?
A tracker mortgage is a type of variable-rate mortgage where the interest rate moves up or down based on a specific reference rate.
In the UK, tracker mortgages usually follow the Bank of England base rate, plus a set percentage known as the lender’s margin.
For example, if your tracker mortgage is set at the Bank of England base rate + 1%, and the base rate is 4%, your mortgage rate would be 5%.
If the base rate rises, your mortgage rate may rise. If the base rate falls, your mortgage rate may fall too.
When Can a Tracker Mortgage Be Useful?
A tracker mortgage can be appealing if you expect interest rates to stay the same or fall.
Because tracker mortgages are linked to a reference rate, they can sometimes offer lower initial rates than fixed-rate mortgages. However, they also carry more risk because your monthly payments can change.
Example:
James owns a buy-to-let property in Manchester. He has a tracker mortgage with a rate of Bank of England base rate + 1%.
When interest rates are low, James benefits from lower monthly payments. But if the Bank of England raises rates, his monthly mortgage payments will increase.
Pros of Tracker Mortgages
Tracker mortgages may be suitable for borrowers who are comfortable with payment changes.
- Initial rates may be lower than some fixed-rate mortgages
- Payments can decrease if interest rates fall
- Clear link to the Bank of England base rate
- Can offer more flexibility depending on the lender and product
- May suit borrowers with room in their budget for payment changes
Cons of Tracker Mortgages
Tracker mortgages can be riskier because repayments are not fixed.
- Monthly payments can rise if interest rates increase
- Budgeting can be more difficult
- Higher repayments may create financial pressure
- Less certainty compared with a fixed-rate mortgage
- Not ideal for borrowers who need stable monthly payments
Fixed vs Tracker Mortgages: Key Differences at a Glance
The table below shows the main differences between fixed-rate mortgages and tracker mortgages.
| Feature | Fixed-Rate Mortgage | Tracker Mortgage |
|---|---|---|
| Interest rate | Fixed for a set period | Variable and usually tracks the Bank of England base rate plus a margin |
| Monthly payments | Stay the same during the fixed term | Can go up or down when the base rate changes |
| Best suited for | Borrowers who want payment certainty | Borrowers comfortable with possible rate changes |
| Risk of rate rises | No rate rise during the fixed period | Payments may increase if the base rate rises |
| Budgeting | Easier to plan | Less predictable |
| Flexibility | May have early repayment charges | Varies by lender and product |
| Potential benefit | Stability and protection from rate rises | Possible lower payments if rates fall |
| Main risk | Could miss out if rates fall | Payments may rise unexpectedly |
Fixed or Tracker Mortgage: Which Is Right for You?
Choosing between a fixed-rate mortgage and a tracker mortgage depends on your personal circumstances, income, financial commitments, future plans, and attitude to risk.
There is no single mortgage type that is right for everyone. The best option depends on what you need from your mortgage.
Consider a Fixed-Rate Mortgage If:
A fixed-rate mortgage may be worth considering if you prefer certainty.
- You want predictable repayments
- You need stable monthly costs for budgeting
- You are concerned about possible interest rate rises
- You plan to stay in your home for the fixed term
- You do not want your payments to change during the deal period
This can be especially useful for first-time buyers, families, and borrowers with a tighter monthly budget.
Consider a Tracker Mortgage If:
A tracker mortgage may be worth considering if you are comfortable with some uncertainty.
- You can manage possible payment increases
- You believe interest rates may stay the same or fall
- You want the possibility of lower initial rates
- You understand how base rate changes affect repayments
- You have enough flexibility in your budget
Tracker mortgages can be suitable for some borrowers, but they need careful consideration because payments can rise.
What About Buy-to-Let Mortgages?
The same fixed vs tracker mortgage choices can apply if you are a landlord with a buy-to-let mortgage.
Some landlords prefer fixed-rate buy-to-let mortgages because they want predictable costs. This can help when calculating rental income, mortgage payments, and other property expenses.
Example:
Emma lets out two flats in Leeds. She chooses a 3-year fixed buy-to-let mortgage to keep her costs stable in the medium term.
This helps her manage rental income and expenses without worrying about interest rate changes during the fixed period.
Alternatively, a buy-to-let investor might choose a tracker buy-to-let mortgage, hoping to benefit from lower rates if interest rates fall. However, they must also accept the risk that payments could increase if rates rise.
Other Mortgage Options: Variable Rate Mortgages
Fixed and tracker mortgages are not the only options available.
There are also other types of variable rate mortgages. These do not always strictly track the Bank of England base rate. Instead, the rate may change at the lender’s discretion.
One common example is a standard variable rate mortgage, often called an SVR mortgage.
An SVR can change when the lender decides to adjust it. This means payments can be less predictable. SVR rates may also be higher than fixed-rate or tracker mortgage deals, depending on market conditions and the lender.
Fixed vs Tracker Mortgages: Simple Summary
A fixed-rate mortgage gives you payment certainty for a set period.
A tracker mortgage gives you a rate that can move up or down, usually in line with the Bank of England base rate.
The key difference is stability versus flexibility.
A fixed-rate mortgage can help protect you from rate rises during the fixed term. A tracker mortgage may allow you to benefit if rates fall, but your payments may also increase if rates rise.
Final Thoughts
Both fixed and tracker mortgages come with pros and cons.
A fixed-rate mortgage may suit borrowers who want stable repayments and easier budgeting. A tracker mortgage may suit borrowers who are comfortable with payment changes and want a mortgage rate linked to the Bank of England base rate.
Understanding how each mortgage type works can help you make a more informed decision.
Before choosing a mortgage, it is important to consider your income, monthly commitments, deposit, credit profile, future plans, and how much risk you are comfortable taking.
