UK Mortgages: Fixed or Tracker? How to Choose

When your mortgage deal is about to end, one question comes up before all the others: should you fix, or go for a tracker? This guide explains how each UK mortgage type works, what the trade-off really is, and how to compare deals side by side so you can choose with a clear head instead of a knot in your stomach.

Key takeaways

  • A fixed rate keeps your payment the same for the deal period, usually 2, 3 or 5 years. A tracker follows Bank Rate plus a set margin, so payments can go up or down.
  • The Bank of England held Bank Rate at 3.75% on 17 September 2026. Check the latest decision before you commit to any deal.
  • Compare the total cost over the deal period, including arrangement fees and early repayment charges, not just the headline rate.
  • Many lenders let you secure a new deal about 3 to 6 months before your current one ends, so start early and avoid drifting onto the standard variable rate.

"Mortgages" has been drawing a lot of searches in the UK this autumn, helped along by the Autumn Budget on 28 October 2026. If your fixed deal ends in the next few months, or you are buying your first home, you are probably reading headlines about rates and wondering what they mean for you. The good news is that the choice becomes much easier once you strip it back to a few simple questions about your budget, your plans and how much uncertainty you can live with.

A quick note before we start: this guide is general information about how mortgages work, not personal financial advice. Your home may be repossessed if you do not keep up repayments, so speak to a qualified mortgage adviser or broker about your own situation before you sign anything.

Where UK mortgage rates stand for 2026

Mortgage pricing does not move in a straight line with any single number, but two figures give you useful context for 2026.

Bank Rate matters most for tracker mortgages, because a tracker moves when Bank Rate moves. Fixed rates are priced differently. Lenders look at what it costs them to borrow money for the length of the fix, which depends on market expectations for rates over the next few years. That is why fixed rates can rise even when Bank Rate stays put.

That is exactly what happened in late summer. Moneyfacts reported that the average two-year fixed mortgage rate rose from 5.63% in early August to 5.73% in mid-September 2026, while Bank Rate was unchanged. Rates and products change often, so treat any figure you read as a snapshot and check the latest Bank of England decision and current lender rates before you choose.

The main UK mortgage types in plain English

Most residential deals fall into four families. Knowing how each one behaves makes the comparison far less confusing.

Fixed rate

Your interest rate, and therefore your monthly payment, stays the same for the deal period. Common lengths are 2, 3 and 5 years. A fix gives you certainty: you know exactly what leaves your account each month, which makes budgeting simple. The trade-off is that if rates fall, you do not benefit until the deal ends, and leaving early usually costs money.

Tracker

A tracker follows Bank Rate plus a margin set by the lender. If Bank Rate goes down, your rate and payment go down too. If it goes up, so does your payment. Some trackers have a "collar," a floor below which the rate cannot fall, so read the terms. Some trackers have lower or no early repayment charges, which can make them more flexible, but always check.

Standard variable rate (SVR)

This is the lender's own variable rate, and it is where you usually land when your deal ends if you do nothing. The lender can change it at its discretion, and it is often higher than the rates on new deals. For most borrowers, sitting on the SVR is a sign that it is time to shop around.

Offset

An offset mortgage links your savings to your mortgage. Instead of earning interest, your savings reduce the balance you pay interest on. Offset deals can be fixed or tracker and can suit people who keep a healthy cash buffer, but the rate may be higher than on a plain deal, so run the numbers.

Pro tip

Before you compare anything, find your current deal's end date and your outstanding balance. Both are usually in your annual mortgage statement or your lender's app. Write them at the top of your comparison sheet so every decision starts from real numbers.

Fixed vs tracker: the real trade-off

The choice comes down to certainty versus flexibility. Neither is "right" in general. The right answer depends on your budget, your plans and your temperament.

Fixed rate suits you if

  • You want a payment that never changes during the deal
  • Your budget has little room for a higher payment
  • You plan to stay in the home for at least the deal period
  • You would lose sleep watching every rate announcement

Tracker may suit you if

  • You could cope comfortably if payments rose
  • You think you might move, sell or overpay soon
  • You value flexibility and lower exit costs, where the deal offers them
  • You are happy to keep an eye on Bank Rate decisions

A useful test is the "stress question." Ask yourself: if my payment went up noticeably next year, could I still pay it without cutting essentials? If the honest answer is no, the certainty of a fix is worth a lot. If the answer is yes and you value flexibility, a tracker is a reasonable option to consider.

Choosing the length of a fix

If you lean toward fixing, the next question is how long. A shorter fix lets you review sooner, which helps if your plans might change. A longer fix gives more years of certainty, but you are tied in longer, and early repayment charges usually apply if you leave during that time. Think about your next few years: a new baby, a business launch, a possible move or a big pay change all point toward matching the fix to your plans.

Fees and charges that change the real cost

The headline rate gets all the attention, but fees can tip the balance between two deals. Look closely at these.

  • Arrangement fees. Some deals with lower rates come with a larger product fee. On a smaller balance, a fee-free deal with a slightly higher rate can work out cheaper overall. You can often pay the fee upfront or add it to the loan, but adding it means paying interest on it.
  • Early repayment charges (ERCs). These apply if you leave a deal early or overpay beyond the allowed limit. They are often a percentage of the balance and can be substantial, so check the ERC schedule for every year of the deal.
  • Overpayment allowances. Many deals let you overpay a certain amount each year without an ERC. If you plan to reduce your balance, check the limit.
  • Valuation and legal fees. Some remortgage deals include these. Others do not. Note which.
  • Exit fees. Your current lender may charge an admin fee when you leave. It is usually smaller than an ERC but still worth including.

Common mistake

Choosing the deal with the lowest rate without adding up the fees. A low rate with a large arrangement fee can cost more over two years than a slightly higher rate with no fee, especially on a smaller mortgage. Always compare the total cost over the deal period.

How to choose a mortgage deal step by step

Here is a simple process you can follow whether you are remortgaging, switching with your current lender or buying.

  1. Note your key dates and numbers. Deal end date, outstanding balance, remaining term and your home's rough value.
  2. Check your budget. Work out the highest monthly payment you could comfortably manage, and how much a rise would hurt.
  3. Decide on your priorities. Certainty, flexibility, the ability to overpay, or the option to move soon.
  4. Get options from your current lender. A product transfer can be quick, so ask what they offer.
  5. Compare the wider market. A broker can compare deals across many lenders, and some deals are only available through brokers.
  6. Compare total costs. Use the template below to add up payments and fees over the deal period.
  7. Secure the deal early. Lock in an offer ahead of your end date, and keep watching. If rates improve before completion, ask whether you can switch.

A simple mortgage deal comparison template

Copy this table into a spreadsheet and add one row per deal. All amounts below are made-up examples for illustration only, not real rates or prices.

Deal C2-year tracker£1,100 (today)£499NoneDepends on Bank RatePayment can change

For the total, multiply the monthly payment by the months in the deal and add the fees. To compare deals of different lengths fairly, look at the same time window, such as the first two years, and note what happens after.

Hypothetical example

Imagine Sam, a self-employed photographer whose 5-year fix ends next spring. Sam's income varies, and a jump in the mortgage payment would squeeze the household budget. Using the made-up figures above, the tracker looks cheapest today, but Sam cannot easily absorb a rise. Sam also plans to stay in the home for years. Deal B, the fee-free 5-year fix, gives the most certainty at a competitive cost, so Sam leans that way. A friend who expects to move within 18 months might pick the tracker with no ERC instead. Same numbers, different lives, different answers.

Timing: when to start looking

As a rule of thumb, many lenders let you secure a new deal about 3 to 6 months before your current one ends. Starting early has two big benefits. First, you avoid rolling onto the standard variable rate while paperwork drags on. Second, you give yourself time to compare calmly instead of grabbing the first offer.

Put a reminder in your calendar six months before your deal ends. At that point, check your credit file, gather recent payslips or accounts, and ask for initial quotes. If you are self-employed, our guide to mortgages for the self-employed covers the extra paperwork.

Pro tip

Keep a "mortgage folder" with your current deal terms, the last annual statement, ID, proof of income and every offer you receive. When a lender or broker asks for something, you can send it the same day, which helps you lock in a deal before it is withdrawn.

Your fixed or tracker checklist

  • Find your current deal end date and outstanding balance
  • Set a reminder for six months before the deal ends
  • Work out the highest monthly payment you can comfortably afford
  • Answer the stress question: could you cope if payments rose?
  • Check the latest Bank of England decision and current lender rates
  • Ask your current lender for product transfer options
  • Speak to a broker to compare deals across lenders
  • Compare total cost over the deal period, including all fees and ERCs
  • Secure your new deal before the current one ends

Frequently asked questions

Is a fixed or tracker mortgage better right now?

There is no single answer. A fix suits people who need payment certainty, while a tracker suits people who can absorb changes and value flexibility. Nobody can reliably predict where rates will go, so choose based on what you can afford and how you would feel if things moved against you.

What happens if my deal ends and I do nothing?

You usually move onto your lender's standard variable rate, which is often higher than new deals. You can normally switch to a new deal at any point after that, but every month on the SVR may cost you more, so act early.

Can I leave a fixed deal early?

Usually yes, but you may pay an early repayment charge. Check your mortgage offer for the ERC schedule. Some deals let you take the mortgage with you if you move home, which can help avoid the charge.

Does the Budget change my mortgage rate?

Not directly. But government borrowing plans can influence markets and expectations for interest rates, which feed into how lenders price fixed deals. Keep an eye on lender rates in the weeks after big announcements.

The bottom line

Choosing between a fixed and a tracker mortgage is really about choosing how much certainty you need. Start with your budget and your plans, compare the total cost of each deal including fees and early repayment charges, and start looking 3 to 6 months before your current deal ends so you never drift onto the SVR.

Set your reminder today, fill in the comparison table with real quotes, and talk to a broker or adviser before you commit. A calm, well-documented decision now can save you money and stress for years.
