Fixed vs Tracker Mortgages: Which Is Right for You in 2026?

Choosing between a fixed rate and a tracker mortgage comes down to one central question: how much certainty do you need, and how much of a chance are you willing to take on your monthly payments changing? Neither option is objectively "better" - a fixed rate protects you from rate rises for a set period, in exchange for an early repayment charge if you leave early, while a tracker mortgage moves in line with the Bank of England base rate, offering more flexibility but no such certainty. This guide compares both in depth, so you can weigh up which suits your circumstances.

Key takeaway: There is no universally "better" option between fixed and tracker mortgages. It comes down to your attitude to risk, how long you plan to stay in the property, and whether you value payment certainty over the chance of paying less right now.

What is a fixed rate mortgage?

A fixed rate mortgage locks your interest rate for an agreed period, commonly 2, 3, 5 or sometimes 10 years. Whatever happens to the base rate or the wider mortgage market during that time, your monthly payment stays the same. When the fixed period ends, you'll usually move onto your lender's standard variable rate (SVR) unless you arrange a new deal, either with your existing lender (a product transfer) or by remortgaging elsewhere.

What is a tracker mortgage?

A tracker mortgage is a type of variable rate mortgage that moves directly in line with, or "tracks", the Bank of England base rate, usually expressed as base rate plus a set margin (for example, base rate plus 0.75%). When the base rate changes, your rate and monthly payment typically change shortly afterwards, in either direction. Most tracker deals run for 2 years, though some ("lifetime trackers") continue for the whole mortgage term.

Fixed rate mortgages: the pros

The main appeal of a fixed rate is certainty. Beyond that, the length of fix you choose is often driven by a specific reason:

• Stable payments through a particular life stage - for example, wanting predictable outgoings while children are young and childcare-related costs are high.
• Timing your next remortgage deliberately - choosing a fixed term that ends when you specifically want to remortgage, for instance because you expect to benefit from a lower rate at that point.
• Planning a large overpayment at a set time - aligning your fixed term with a point in the future when you intend to make a significant lump sum reduction, since large overpayments beyond your fee-free allowance can trigger a charge during the fixed period.

Whatever happens to fixed or tracker rates elsewhere in the market during your term, your payment does not change, which makes budgeting straightforward.

Fixed rate mortgages: the downsides

• Early repayment charge (ERC) - leaving your fixed deal early, whether to remortgage, move home in a way that requires a new mortgage, or overpay beyond your allowance, will usually trigger a charge, typically 1-5% of your outstanding balance depending on how far through the term you are.
• No benefit if rates fall - if fixed or tracker rates drop after you've fixed, you stay on your original rate until the term ends.
• Less flexibility during the term - restructuring your borrowing, such as raising further funds or changing the term, is more limited while you're tied into a fixed deal.

Example: On a £250,000 mortgage with an ERC of 3%, leaving your fixed deal early could cost in the region of £7,500. It's worth being confident about your plans for the fixed period before you commit.

Can you borrow more with a fixed rate mortgage?

In some cases, yes. A number of lenders offer their highest income multiples specifically on longer-term fixed rate products, since a 5-year fix gives the lender more confidence in the stability and predictability of your repayments over that period.

• Nationwide's Helping Hand offers first-time buyers up to 6 times income on their 5-year fixed rate product.
• Leeds Building Society's Income Plus offers first-time buyers up to 5.5 times income, also on a 5-year fixed rate.
• Lenders including NatWest, Halifax and Santander also tend to offer their higher borrowing amounts on 5-year fixed rate products rather than shorter fixes or trackers.

This is worth factoring into your decision if maximising your borrowing is a priority, not just the rate itself. Our guide on how much you could borrow in 2026 covers income multiples in more detail, and if you're a first-time buyer specifically, our guide to preparing for your first property is a useful next step.

Tracker mortgages: the pros

• Often no early repayment charge - many tracker deals let you move home, remortgage or repay your mortgage in full without a penalty, though this varies by product, so always check.
• Frequently unlimited overpayment allowances - rather than the roughly 10%-a-year fee-free limit common on fixed deals, many trackers allow unlimited fee-free overpayments, useful if you want to reduce your balance more aggressively.
• Freedom to switch to a fixed rate later - many tracker deals let you move to a fixed rate at any point during the term without an ERC, so you can lock in certainty later if your circumstances or the rate environment change.
• Often a lower starting rate - tracker rates have historically tended to start lower than equivalent fixed rates, though this isn't guaranteed and the gap between the two changes over time.

Tracker mortgages: the downsides

• Payments can rise as well as fall - shortly after any base rate increase, your monthly payment will typically go up, which can make budgeting harder if you have little room to spare.
• No certainty over total cost - you won't know in advance exactly what you'll pay in total over the tracker period.
• Could end up costing more than a fixed rate would have - if the base rate rises significantly and stays higher for an extended period, a tracker can work out more expensive than a fixed rate taken at the same time.
• Lifetime trackers carry longer exposure - these often start with a lower margin above base rate, but leave you exposed to rate movements for the whole mortgage term rather than just 2 years.
• Subject to availability - not every lender offers a competitive tracker range. If your circumstances limit your choice of lender, for example due to your income type, credit profile, or other specialist criteria, you may find fewer or less competitive tracker options available, which can effectively steer you towards a fixed rate product instead.

How does loan to value (LTV) affect your choice?

Your loan to value (LTV) is the size of your mortgage compared with your property's value, expressed as a percentage. Lenders group their rates into LTV bandings, for example up to 60%, up to 75%, up to 90% or up to 95%, and the higher your LTV, the higher the rate banding you're usually charged, on both fixed and tracker products.

If you lock into a 95% LTV fixed rate for 5 years, you'll typically be paying one of the highest rate bandings for the whole term, even if your LTV improves along the way. If you're planning home improvements, or intend to make large overpayments, either of which can increase your property's value and reduce your LTV banding, a tracker mortgage may suit you better. Without an early repayment charge tying you in, it can be easier to remortgage onto an improved LTV banding as soon as your circumstances allow, rather than waiting out a fixed term first.

What's happening with the "fixed-rate cliff edge" in 2026?

Around 1.8 million UK fixed-rate mortgage deals are due to end during 2026, more than the roughly 1.6 million that matured in 2025. Many of these were taken out when rates were considerably lower than they have been more recently, which can mean a noticeably higher monthly payment for borrowers rolling off an older deal onto a new one.

If your fixed deal is ending this year, it's worth reviewing your options in good time. Most lenders let you arrange a new deal several months before your current one finishes, and your choice at that point is broadly the same one this guide covers: a new fixed rate, a tracker, or (usually the least favourable option) doing nothing and moving onto your lender's standard variable rate, which is typically the most expensive of the three.

Which should you choose: fixed or tracker?

Neither a fixed rate nor a tracker mortgage is inherently better. The right choice depends on your attitude to risk and what suits your circumstances right now, not a one-size-fits-all rule.

• A fixed rate may suit you if you value predictable payments, would rather not take on any risk of payments rising, or have a specific date in mind for a life change, a planned remortgage, or a lump sum overpayment.
• A tracker may suit you if you can comfortably absorb some payment fluctuation, want the flexibility to overpay or move home without a penalty, or want to benefit from a potentially lower starting rate while keeping the option to fix later.

A whole-of-market mortgage adviser can talk you through both scenarios using your own numbers, so you're choosing with your eyes open rather than guessing. If you'd also like to check your borrowing power before deciding, our guide on how much you could borrow in 2026 is a useful next step.

Frequently asked questions

Can I switch from a tracker to a fixed rate mortgage?

Often, yes. Many tracker mortgages let you switch to a fixed rate at any point during the tracker term without an early repayment charge, though this varies by lender and product, so it's worth checking your specific terms.

What happens when my fixed rate ends?

Unless you arrange a new deal, you'll move onto your lender's standard variable rate (SVR), which is usually considerably higher than typical fixed or tracker rates. Most lenders let you arrange a new deal a few months before your current one ends, so it's worth reviewing your options in advance.

Is a tracker mortgage riskier than a fixed rate?

A tracker carries more uncertainty, since your payments can rise as well as fall if the Bank of England base rate changes. Whether that counts as riskier for you depends on how comfortable you are with payment fluctuation and how much headroom you have in your monthly budget.

Can I overpay on a fixed rate mortgage?

Usually, yes, up to a set annual allowance, commonly around 10% of the outstanding balance, without triggering an early repayment charge. Overpaying beyond that limit during the fixed term can trigger a charge, so check your specific deal before making a large lump sum payment.

Should I fix for 2 years or 5 years?

This depends on your plans rather than a fixed rule. A shorter fix can suit you if you expect your circumstances or the rate environment to change soon, while a longer fix can suit you if you want payment certainty for longer, such as through a specific life stage.

Does everyone qualify for a tracker mortgage?

Not necessarily. Tracker mortgages are subject to availability, and not every lender offers a competitive tracker range. If your circumstances limit your choice of lender, for example due to your income type, credit profile, or other specialist criteria, you may find fewer or less competitive tracker options available, which can effectively steer you towards a fixed rate product instead. A whole-of-market adviser can confirm which options are realistically open to you.

What's the difference between a tracker and a discount mortgage?

Both are variable rate mortgages, but they work differently. A tracker mortgage moves directly in line with the Bank of England base rate, while a discount mortgage is set at a discount to the lender's own standard variable rate (SVR), which the lender can change independently of the base rate. This means a discount mortgage can be less predictable, since it isn't tied to a rate set by the Bank of England.

Can part of my mortgage be fixed and part on a tracker?

Some lenders offer "part and part" mortgages, letting you split your borrowing between a fixed rate portion and a tracker portion. This can suit borrowers who want some payment certainty alongside some flexibility, though not all lenders offer this option, so it's worth discussing with an adviser if it interests you.

Does choosing a fixed rate mean I can borrow more?

It can. Some lenders offer their highest income multiples specifically on 5-year fixed rate products, since the longer-term stability gives them more confidence in your ability to maintain repayments. This varies by lender, so it's worth checking whether a fixed rate could also improve how much you're able to borrow, not just your payment certainty.
