What Happens When Your Fixed-Rate Mortgage Ends?
A fixed-rate mortgage gives you certainty for a set period of time. For two, three, five or sometimes ten years, your interest rate stays the same, which means your monthly repayments are easier to plan around.
But a fixed rate does not last forever.
When your fixed mortgage deal ends, your interest rate will usually change unless you arrange a new mortgage product. For many homeowners, this can be the moment when monthly repayments rise, especially if the original deal was taken during a period of much lower interest rates.
If your fixed-rate mortgage is due to end soon, it is worth understanding what happens next, what your options are, and why leaving things too late can reduce the number of choices available to you.
The quick answer: what happens when a fixed rate ends?
When your fixed-rate mortgage ends, the special fixed interest rate you agreed with your lender comes to an end.
Unless you arrange a new deal, you will usually be moved onto your lender’s standard variable rate, often shortened to SVR. MoneyHelper explains that fixed-rate deals normally move to the lender’s SVR unless you get a new deal or remortgage.
That means:
Your interest rate may no longer be fixed.
Your monthly mortgage payment may go up or down.
Your lender can usually change its SVR.
You may pay more than you would on a new fixed, tracker or product-transfer deal.
You may have more flexibility, but often at a higher monthly cost.
For many borrowers, the main risk is simple: doing nothing can mean paying more than you need to.
What is a standard variable rate?
A standard variable rate is the rate your lender charges once your initial mortgage deal ends and no new product has been arranged.
Unlike a fixed-rate mortgage, an SVR can change. It is set by the lender and may move in response to wider interest-rate changes, funding costs, market conditions, or the lender’s own pricing decisions.
That does not mean every borrower should automatically avoid SVR in every situation. Some people use it temporarily because it may offer flexibility, especially if they are planning to sell, repay a large amount, or wait before choosing a new deal. But for many homeowners, staying on SVR long-term can be expensive.
Why can repayments rise when your fixed rate ends?
Your repayment changes because the interest rate changes.
If you fixed your mortgage at a low rate and the rates available today are higher, your new monthly payment may increase when you remortgage, switch product, or move onto SVR.
This has become a major issue for many UK homeowners because a lot of borrowers fixed their mortgage during the ultra-low-rate period.
The Bank of England says Bank Rate was 0.1% at the beginning of December 2021 and is 3.75% now. It also notes that Bank Rate was below 1% from April 2020 to May 2022. Bank of England rate-history data shows Bank Rate rose through 2022 and 2023, reaching 5.25% in August 2023, before later falling to 3.75% in December 2025.
That matters because mortgage pricing is strongly influenced by the wider interest-rate environment.
So, if you secured a two-year or five-year fixed rate during a much cheaper period, the new deals available when your current fix ends may still be higher than the rate you originally had.
Example: why even a small rate change matters
The exact impact depends on your mortgage balance, term, rate and repayment type.
As a simple illustration, on a repayment mortgage of £180,000 over 20 years:
At 2.00%, the payment would be roughly £911 per month.
At 4.75%, the payment would be roughly £1,163 per month.
At 6.75%, the payment would be roughly £1,369 per month.
That is only an example, but it shows why the end of a fixed-rate deal can feel significant. The mortgage balance may be the same, the house may be the same, and the borrower’s circumstances may be similar — but the interest-rate environment can make the monthly payment very different.
Your main options when a fixed-rate mortgage ends
When your fixed mortgage deal is coming to an end, you generally have three broad routes to consider.
Option 1: switch to a new deal with your current lender
This is often called a product transfer or rate switch.
A product transfer means you stay with your existing lender but move onto a new mortgage product, such as another fixed rate or a tracker deal.
This can be simpler than a full remortgage because you are not moving the mortgage to a different lender. In some cases, there may be less paperwork, fewer legal requirements, and no full affordability assessment.
The GOV.UK Mortgage Charter says customers who are up to date with payments can be supported to switch to a new mortgage deal at the end of their fixed rate without another affordability check. It also says participating lenders allow customers approaching the end of a fixed rate to lock in a deal up to six months ahead and request a better like-for-like deal before the new term starts if one is available.
A product transfer can be useful if:
You want a relatively straightforward option.
Your circumstances have changed and a full remortgage may be harder.
You are happy with your current lender’s available rates.
You want to avoid some of the work involved in changing lender.
However, it may not always be the cheapest or most suitable option. Your current lender can only offer its own products, while a wider remortgage search may show alternatives elsewhere.
Not sure whether to stay, switch or remortgage?
Choosing what to do when your fixed rate ends is not always straightforward. Your current lender may offer a simple product transfer, but a wider remortgage search could reveal other options.
A mortgage review can help you compare both routes and understand the costs, fees and potential repayment difference.
Option 2: remortgage to a new lender
Remortgaging means switching your mortgage from your current lender to a new lender.
This can give you access to a wider range of mortgage deals, which may include lower rates, different fixed-rate periods, tracker options, offset mortgages, or products that better match your circumstances.
A remortgage may be worth exploring if:
You want to compare the wider market.
Your loan-to-value has improved.
Your income or credit profile is strong.
You want to borrow more, subject to affordability and criteria.
You want a different mortgage type or term.
The trade-off is that remortgaging usually involves a fuller application process. The new lender will normally assess your income, outgoings, credit profile, property value and overall affordability.
There may also be costs to think about, such as arrangement fees, valuation fees, legal work, or exit fees from your current lender. Some remortgage products include free valuation or legal support, but this depends on the lender and product.
The key point is not just to chase the lowest headline rate. The best option may depend on the total cost, including fees, incentives, term, flexibility, overpayment rules and your future plans.
Option 3: move onto SVR temporarily
You can usually allow your mortgage to move onto your lender’s SVR.
This may not require a new application, and it can provide flexibility because SVRs often do not have the same early repayment charges as fixed-rate deals. That can be useful if you are planning to sell soon, repay the mortgage, or wait before committing to a new deal.
But SVR is often more expensive than other available mortgage products. MoneyHelper says SVRs will usually be higher than other rates you may be able to get elsewhere, and that borrowers should check whether switching to a new mortgage deal could save money.
SVR may be a short-term holding position, but it should usually be a conscious decision rather than something that happens because you forgot to review your mortgage.
Fixed rate ending soon?
If your mortgage deal is due to end in the next 6 months, it may be worth reviewing your options before you move onto your lender’s standard variable rate.
You can request a mortgage review to compare your current lender’s options with wider remortgage deals and understand what your next monthly payment could look like.
When should you start looking before your fixed rate ends?
A good rule of thumb is to start looking around six months before your fixed rate ends.
Starting early gives you time to: Check what your current lender will offer.Compare remortgage options with other lenders. Understand whether your circumstances still fit lender criteria. Avoid being rushed onto SVR. Secure a new rate before your current deal ends. Review fees, early repayment charges and total cost.
In some cases, you may be able to lock in a new deal months before your current rate finishes. If rates improve before completion, some lenders may allow changes, but this depends on the lender’s rules and the specific product.
That is why it is important to understand the terms before committing.
What should you consider before choosing your next deal?
The right mortgage route depends on your circumstances. Before deciding what to do next, it may help to think about the following points.
How long do you plan to stay in the property?
If you expect to move soon, a long fixed-rate deal with early repayment charges may not suit you unless it is portable and the lender agrees to transfer it to a new property.
If you plan to stay long-term, you may value payment certainty.
Do you want stability or flexibility?
A fixed-rate mortgage gives certainty because your payment stays the same during the deal period.
A tracker or variable product may move up or down, which can be useful if rates fall but risky if they rise.
SVR may offer flexibility but can be more expensive.
Has your income changed?
If your income has fallen, you have become self-employed, changed job, taken on more credit, or had a major life change, your remortgage options may be different from the last time you applied.
That does not mean you have no options, but it does mean you should review things early.
Has your property value changed?
Your loan-to-value, or LTV, can affect the rates available to you.
If your property has increased in value or your mortgage balance has reduced, you may now fall into a lower LTV band. That could improve the range of deals available.
If your property value has fallen, or your borrowing remains high compared with the property value, options may be more limited.
Are there fees or early repayment charges?
Some mortgage deals come with arrangement fees. Others have lower fees but higher rates.
A deal with the lowest rate is not always cheapest overall. You need to look at the total cost over the period you expect to keep the mortgage.
You should also check whether your current fixed deal has an early repayment charge if you switch before the end date.
Are you looking to borrow more?
Some borrowers review their mortgage because they want to raise additional funds, perhaps for home improvements, debt consolidation, or another purpose.
Additional borrowing depends on lender criteria, affordability, property value and the reason for the borrowing. It should be considered carefully because it may increase the amount secured against your home and could increase total interest paid.
What if you are worried about the new payment?
If your fixed rate is ending and you are worried about the payment increase, do not ignore it.
You can contact your lender to understand what support may be available. The Mortgage Charter says borrowers worried about repayments can contact their lender for help and guidance without any impact on their credit file.
Depending on your situation, options may include reviewing a new deal, looking at term changes, temporary support, or wider budgeting support.
If you are already struggling, speaking to your lender early is usually better than missing payments without contact.
Is it better to fix again or choose a tracker?
There is no single answer.
A fixed rate may suit borrowers who want certainty and need to know exactly what they will pay each month.
A tracker may suit borrowers who are comfortable with payments moving and who want the possibility of benefiting if rates fall.
SVR may suit a borrower who needs short-term flexibility, but it can be expensive if used for too long.
The right choice depends on your attitude to risk, your monthly budget, your future plans and the deals available at the time.
Should you use a mortgage adviser?
A mortgage adviser can help you compare options, especially if your situation is not straightforward.
This may be useful if:
Your fixed rate ends soon.
You are unsure whether to stay with your lender or remortgage.
Your income has changed.
You are self-employed.
You have credit issues.
You want to borrow more.
You are worried about affordability.
You want someone to compare product transfers against wider market options.
A mortgage review does not force you to switch. It simply helps you understand what may be available and what the next step could look like.
Fixed rate ending soon? Do not leave it until the last minute
The end of a fixed-rate mortgage is one of the most important review points in homeownership.
If you do nothing, you may move onto your lender’s SVR. That might be flexible, but it can also be more expensive than other available options.
By reviewing your mortgage early, you can compare your current lender’s offer against wider remortgage options, understand the potential payment change, and avoid making a rushed decision.
Review your mortgage before your fixed rate ends
If your fixed-rate mortgage is coming to an end, the worst option is usually leaving it until the last minute.
Your lender may move you onto its standard variable rate if no new deal is arranged, which could mean higher monthly repayments. Reviewing your mortgage early gives you time to compare options, check affordability and decide whether staying with your lender or remortgaging could be more suitable.
A mortgage review can help you understand:
- What your current lender may offer
- Whether a remortgage could reduce your monthly payment
- How much your repayments could change
- Whether fixed, tracker or variable options may suit your circumstances
- What fees or early repayment charges may apply
Request a mortgage review today and explore your options before your fixed rate ends.
