Fixed vs Tracker Mortgage: Which Is Right for You?

Choosing between a fixed vs tracker mortgage is one of the biggest decisions you will make when you remortgage or buy. A fixed rate gives you certainty; a tracker moves with the Bank of England base rate, so your payments can rise or fall. Neither is automatically better. The right choice depends on your budget, your appetite for risk and your view on where rates are heading.

This guide compares the two properly, with the pros and cons of each and who they tend to suit. For the wider process, see our pillar guide, remortgaging explained.

How a fixed-rate mortgage works

With a fixed-rate mortgage, your interest rate is locked for a set period, commonly two, three or five years, and sometimes ten. Your monthly payments stay exactly the same for that period, regardless of what happens to the base rate.

When the fixed period ends, you typically move onto the lender's standard variable rate, which is why most people remortgage or take a new deal at that point.

How a tracker mortgage works

A tracker mortgage follows the Bank of England base rate plus a set margin. For example, a tracker at "base rate plus 0.75%" means if the base rate is 4%, you pay 4.75%. If the base rate rises, your payments rise; if it falls, your payments fall.

Trackers usually run for a set period too, often two or five years, after which you move onto the standard variable rate.

It is worth distinguishing trackers from two related variable products:

• Discount rate — a discount off the lender's own SVR, which the lender can change independently of the base rate.
• Standard variable rate (SVR) — the lender's default rate once a deal ends, usually the most expensive and entirely at the lender's discretion.

A tracker is more transparent than either, because it moves only with the base rate, not at the lender's whim.

Fixed vs tracker: a side-by-side breakdown

Fixed rate

• Payments: the same every month for the fixed period.
• If rates rise: you are protected; your payments do not change.
• If rates fall: you do not benefit; you stay on your fixed rate.
• Budgeting: easy and predictable.
• Early repayment charges: usually apply for the whole fixed period.
• Best when: you value certainty or think rates may rise.

Tracker rate

• Payments: move up or down with the base rate.
• If rates rise: your payments increase.
• If rates fall: your payments decrease.
• Budgeting: less predictable.
• Early repayment charges: some trackers have none, giving flexibility to switch or overpay.
• Best when: you can absorb rate rises or think rates may fall.

Pros and cons of a fixed rate

Pros

• Complete payment certainty for the fixed period.
• Protection if interest rates rise.
• Straightforward budgeting.

Cons

• You will not benefit if rates fall.
• Early repayment charges usually apply if you leave early.
• Fixed rates can start higher than the initial tracker rate when rates are expected to fall.

Pros and cons of a tracker rate

Pros

• You benefit immediately if the base rate falls.
• Some trackers have no early repayment charges, so you can overpay or switch freely.
• Transparent, as it moves only with the base rate.

Cons

• Payments can rise, sometimes sharply, if the base rate climbs.
• Harder to budget with certainty.
• Requires financial headroom to absorb increases.

Who does each suit?

A fixed rate tends to suit you if:

• You are on a tight or fixed budget and need to know your payments.
• You would worry about rate rises.
• You are buying at the top of your affordability and cannot absorb higher payments.
• You believe rates are more likely to rise than fall.

A tracker tends to suit you if:

• You have financial headroom to cope with payment increases.
• You want flexibility, particularly a deal with no early repayment charges.
• You expect the base rate to fall and want to benefit.
• You may want to move or repay the mortgage before a fix would end.

What about early repayment charges?

Early repayment charges (ERCs) matter to this decision. Most fixed deals lock you in with an ERC for the whole period, so leaving early can be costly. Some trackers, by contrast, are fully flexible with no ERC, which is attractive if you might move, come into a lump sum, or want to switch to a fix later. Always check the ERC terms before committing, as they shape how much freedom you have.

Can you hedge your bets?

If you cannot decide, there are middle paths. Some borrowers with larger loans split their mortgage into two parts, part fixed and part tracker, to balance certainty with flexibility. Others choose a shorter fix to revisit the decision sooner. An adviser can talk you through whether either approach fits your situation.
