One of the most common decisions you will face when taking out or remortgaging is whether to choose a fixed rate or a tracker rate. There is no universally right answer - it depends on your circumstances, your attitude to risk, and what is happening with interest rates at the time. This guide explains how each type of mortgage works and what to think about when making the choice.

What is a fixed rate mortgage?

A fixed rate mortgage locks your interest rate in for a set period - typically two, three, or five years, though longer fixed periods of up to ten years are also available. During that period, your monthly payment stays the same regardless of what happens to the Bank of England base rate or wider interest rate movements.

At the end of the fixed period, you will move onto the lender's standard variable rate unless you remortgage. The standard variable rate is almost always higher than the fixed rate you were on, which is why most people remortgage when their deal ends rather than sitting on it.

What is a tracker mortgage?

A tracker mortgage follows an external rate - usually the Bank of England base rate - with a set margin added on top. For example, a tracker might be described as base rate plus 0.75%. If the base rate is 4.5%, you would pay 5.25%. If the base rate rises to 5%, your rate goes up to 5.75%. If it falls, your rate falls with it.

Trackers are usually available for an initial period - typically two or five years - though some lenders offer lifetime trackers that run for the full mortgage term. Unlike fixed rates, tracker mortgages often have no early repayment charges, or lower ones, which can give you more flexibility.

What are the advantages of a fixed rate?

The main advantage of fixing is certainty. You know exactly what your mortgage payment will be for the duration of the fixed period, which makes budgeting straightforward. This is particularly valuable for first-time buyers or anyone who needs their finances to be predictable.

A fixed rate also protects you if interest rates rise during the fixed period. If base rate goes up significantly after you have locked in, you will be insulated from the increase while your deal runs.

The trade-off is that if rates fall, you will not benefit - you are locked in at the higher rate until the fixed period ends, unless you pay an early repayment charge to exit.

What are the advantages of a tracker rate?

A tracker mortgage can work in your favour when interest rates are falling or expected to fall. If the base rate drops during your tracker period, your monthly payment reduces automatically - no remortgage required.

Trackers also tend to offer more flexibility. Many have no early repayment charges, which means you can overpay freely, switch products, or pay off the mortgage entirely without penalty. This can be valuable if you think you might want to sell, remortgage, or make significant overpayments during the period.

The risk is that rates could rise. If the base rate increases significantly while you are on a tracker, your payment goes up and there is no ceiling unless your mortgage includes a cap - which some do, but many do not.

How do you decide which is right for you?

The right choice depends on several factors.

Your appetite for risk is the starting point. If payment certainty matters more to you than the possibility of paying less, a fixed rate is likely the better fit. If you can absorb potential payment increases and want to benefit if rates fall, a tracker is worth considering.

Your plans for the property also matter. If you are likely to sell or remortgage within the next two or three years, a tracker with no early repayment charges may give you more flexibility than a fixed rate that could lock you in with significant exit costs.

The current interest rate environment is relevant too. When rates are widely expected to fall, the case for a tracker is stronger. When rates are expected to rise or stay high, fixing gives you protection. Nobody can predict rate movements with certainty, but understanding the general outlook is part of making an informed decision.

Finally, your financial resilience matters. If your budget is tight and a rate rise of one percentage point would cause you real difficulty, the certainty of a fixed rate is worth paying for.

Is there a middle ground?

Some lenders offer discounted variable rate mortgages, where the rate is set at a fixed discount below the lender's standard variable rate for a period. These can offer lower starting rates than fixed products but carry the same variability risk as a tracker. They are less common than they once were but worth knowing about.

A good adviser will present the options available across the market - not just push you towards one product type - and help you weigh up which approach genuinely suits your situation.
