What happens when a fixed-rate mortgage ends?

When your fixed-rate mortgage term is coming to an end, it’s easy to assume the next step will be automatic. In many cases, it is—but that doesn’t always mean it’s the best outcome for your budget.

As your fixed period finishes, your mortgage will usually move onto your lender’s Standard Variable Rate (SVR) unless you take action to switch to a new deal. SVR rates can change over time, and that can mean your monthly payment may rise.

This guide explains what typically happens at the end of a fixed rate and the main options homeowners consider, so you can plan ahead with confidence.

What is a fixed-rate mortgage?

A fixed-rate mortgage sets your interest rate for a defined period—commonly 2, 5, or 10 years. During the fixed term, your interest rate (and therefore your monthly payment, if your mortgage is set up that way) is designed to stay predictable.

The trade-off is that once the fixed term ends, the mortgage rate usually changes. Most commonly, it moves to the lender’s SVR, which is not fixed and can fluctuate.

What happens when your fixed rate ends?

In most situations, when the fixed period ends:

• your lender will end the fixed-rate arrangement
• your mortgage will typically move to the lender’s SVR (unless you’ve arranged a new product)
• your monthly payment may change because SVR interest rates can be higher than fixed rates and can vary

The key point is that the change may happen without you needing to do anything—but you generally have to do something if you want to avoid moving onto SVR.

Why SVR can feel like a shock

Many borrowers experience a noticeable increase in payments when they move from a fixed rate to SVR. That’s because SVR is often priced differently from fixed deals and may reflect broader interest rate conditions.

Even if the increase isn’t immediate, SVR can still move over time. That means your repayments may become less predictable compared with your fixed term.

Your options after a fixed rate ends

You’re not limited to staying on SVR. The main options are:

1) Remortgage to a new deal (often a common route)

Remortgaging means taking out a new mortgage—either with your current lender or a different one—to replace your existing deal.

Depending on your circumstances, remortgaging can be used to:

• secure a new fixed rate (or another product type)
• adjust the mortgage term
• change the repayment structure (where appropriate)
• borrow additional funds if you need to (subject to affordability and lender criteria)

2) Switch to a different product with your current lender

Some borrowers prefer to stay with their existing lender and move onto a new product offered by that lender. This can be suitable where the lender can offer a deal for your remaining term.

It’s still worth comparing options, because the “best” deal isn’t always the one your current lender automatically offers.

3) Switch to a tracker or discounted rate (if it suits your risk)

Some mortgages allow you to move to products where the interest rate follows a reference rate (for example, the Bank of England base rate) or where a discount applies.

These can reduce the cost if rates fall, but they also introduce more variability. If you’re considering this route, it helps to be clear about how changes could affect your monthly payments.

4) Stay on SVR (sometimes the right choice, but plan for it)

Some homeowners decide to remain on SVR, particularly if they expect to move soon, plan to repay the mortgage early, or want flexibility.

However, staying on SVR usually means accepting:

• potentially higher repayments
• less certainty about future costs

If you choose this option, it’s sensible to model what your repayments could look like under different interest rate scenarios.

Timing: when to start planning

Planning ahead is one of the biggest factors in avoiding an expensive or inconvenient outcome.

A practical approach is to start reviewing options around 3 to 6 months before your fixed term ends. This gives time to:

• compare available deals
• gather information needed for a remortgage application
• complete any required checks and documentation
• ensure the new mortgage is in place before the fixed rate finishes

Delaying can reduce your options and increase the chance you’ll fall onto SVR.

What to watch out for when switching

When you move away from a fixed rate, a few cost and process points can affect the overall outcome.

Early repayment charges (ERCs)

If you switch before the end of your fixed term, you may face early repayment charges. If your fixed term has genuinely ended, ERCs typically won’t apply in the same way—but it’s still important to confirm the timing.

Arrangement fees and other costs

Some mortgage deals include arrangement fees. A lower interest rate doesn’t always mean a better overall deal if fees are high, so it’s worth considering the total cost over time.

Valuation and lender checks

Remortgaging often involves lender processes such as affordability checks and, in some cases, property valuation. Having key documents ready can help avoid delays.

Mortgage term and repayment strategy

Your decision may be influenced by whether you’re aiming to reduce monthly payments, clear the mortgage sooner, or balance short-term affordability with longer-term cost.

How to compare your next deal

Mortgage products change frequently, and the “best” option depends on more than just the headline rate.

When comparing, it helps to consider:

• the length of the new fixed period (and what happens after it ends)
• the total cost including fees
• how the repayment amount changes under different interest rate assumptions
• whether the deal aligns with your plans (staying put, moving, or making overpayments)

A structured comparison can make it easier to choose a deal that fits your circumstances rather than simply reacting to SVR.

Key takeaway

When a fixed-rate mortgage ends, your lender will usually move you onto SVR unless you arrange a new deal. The most effective way to manage this transition is to plan early, understand your options, and choose a mortgage strategy that matches your budget and risk comfort.
