Many homeowners assume their mortgage will simply carry on as normal when a fixed-rate deal ends. In reality, this is one of the most important points in the life of a mortgage deal.
If nothing is done, the loan usually moves automatically onto the lender’s Standard Variable Rate (SVR). That rate is often much higher than the fixed rate that was previously in place.
Because of this, monthly payments can rise quickly. Understanding what happens at this stage helps borrowers avoid unnecessary costs and decide whether switching deals makes sense.
What Happens After a Fixed Mortgage Deal Ends
A fixed-rate mortgage keeps your interest rate locked for a set period. That might be two years, five years, or sometimes longer.
When that deal finishes, the mortgage itself does not end. What changes is the interest rate applied to the loan.
In most instances, the lender moves the mortgage onto their Standard Variable Rate (SVR). This rate can change over time and is often higher than the fixed rate that came before it.
If no new deal is arranged, the mortgage simply continues on that SVR. Because the rate is usually higher, monthly payments can increase quite quickly.
For that reason, many homeowners start reviewing their mortgage options with different mortgage lenders before their fixed deal comes to an end.
Understanding the Standard Variable Rate (SVR)
When a fixed or introductory mortgage deal ends, most lenders move the loan onto their Standard Variable Rate, usually called the SVR. This becomes the default interest rate unless a new mortgage deal is arranged.
Unlike a fixed rate, the SVR can change at any time. It is often influenced by movements in the Bank of England base rate, but lenders are free to adjust it as they see fit.
SVR rates are often higher than many new mortgage deals available on the market. Even a small difference in interest rates can add up to thousands of pounds in extra interest over time.
Because the rate can change, monthly payments may also rise or fall. This makes long-term budgeting more difficult for many homeowners.
For that reason, many borrowers start reviewing their mortgage options by comparing mortgage deals before their fixed deal ends, rather than allowing the loan to move onto the SVR.
How Much Can Mortgage Payments Increase After a Fixed Rate Ends?
When a fixed mortgage deal ends, the rate on the loan often changes. Many mortgages move onto the lender’s Standard Variable Rate (SVR).
If that happens, monthly payments can rise. How much depends on the mortgage balance, the remaining term and the difference between the old fixed rate and the lender’s SVR.
Example: How Payments Can Rise After a Fixed Rate Ends
One thing that often catches homeowners off guard is how much payments can rise once a mortgage moves onto the lender’s Standard Variable Rate. The increase depends on the balance, the remaining term and the difference between the old fixed rate and the new one.
Take a simple example.
- Mortgage balance: £250,000
- Remaining term: 25 years
- Previous fixed rate: 2.2%
- Monthly payment: about £1,085
If the fixed deal ends and the loan moves onto an SVR of around 6.5%, the monthly payment could rise to roughly £1,690.
That’s more than £600 extra each month – an increase of over 55%.
For many households that kind of jump is noticeable. Even borrowers who can manage the higher payment often start looking at new mortgage deals rather than staying on the SVR.
How Lenders Notify Borrowers
Lenders do not move a mortgage onto the Standard Variable Rate without warning. Most borrowers receive a reminder a few months before their fixed deal is due to end.
In many cases this notice arrives around three to six months before the expiry date.
The letter or email usually outlines:
- when the fixed rate will end
- the lender’s current Standard Variable Rate
- product transfer options with the same lender
- details on how to review alternative mortgage deals
The idea is to give borrowers enough time to decide what they want to do next.
In reality, many homeowners put the letter aside and plan to deal with it later. If nothing is arranged before the fixed term ends, the mortgage can move onto the SVR while a new deal is being arranged.
Because of that, some borrowers choose to speak with a mortgage broker and compare options across different lenders rather than relying only on the lender’s default rate.
Product Transfer vs. Remortgage
When a fixed-rate deal ends, most borrowers face two main choices: switching to a new product with their current lender or moving the mortgage to a different lender through a remortgage. If you want to understand the process in more detail, you can also read our remortgaging guide.
A product transfer means choosing a new mortgage deal with the same lender. This is often the simpler option because the lender already holds the mortgage. In many cases there is little paperwork and a new property valuation or full affordability checks may not be required.
A remortgage involves moving the loan to a different lender. This normally requires a full application, affordability checks and a property valuation. The process can take longer, but it gives borrowers access to the wider mortgage market.
Because of that, many homeowners compare deals across several lenders before deciding whether staying put or switching lender offers better long-term value.
What Types of Deals Can Replace a Fixed Rate?
When a fixed mortgage deal ends, most borrowers move onto a new mortgage product. If you want to see how the main mortgage types work, it can help to review the options before deciding.
Some borrowers simply take another fixed-rate deal so their payments stay predictable for a few more years. Others move onto a tracker mortgage, where the rate rises or falls with the Bank of England base rate.
Some lenders also offer discounted variable deals for a short period.
In the end it usually comes down to a simple choice – keeping payments steady with a fixed rate or taking a variable deal where the rate can change.
Why Timing Matters
Timing can make a real difference when a fixed mortgage deal is coming to an end. Many homeowners start reviewing their options around three to six months before the fixed rate expires.
A lot of lenders allow borrowers to secure a new deal in advance while keeping their current rate until the fixed term finishes. This gives time to complete the application without the risk of moving onto the Standard Variable Rate.
Starting early also means borrowers can watch how mortgage rates are moving and secure a new deal before rates change.
If nothing is arranged before the fixed rate ends, the mortgage may move onto the lender’s SVR while a new application is processed. Even a short period on a higher rate can increase the overall cost of the loan.
Because of that, many homeowners review their mortgage options with an independent mortgage advisor well before the end date rather than leaving the decision until the last minute.
Risks of Waiting Too Long
Many homeowners delay reviewing their mortgage because they are comfortable with their current deal. But leaving it too late can create a few problems.
First, mortgage rates may change between the time you start looking and the point you secure a new deal. Rates can move quickly, especially when markets are uncertain.
Second, if the fixed rate ends before a new deal is arranged, the mortgage can move onto the lender’s Standard Variable Rate. Even a short period on SVR can mean noticeably higher monthly payments.
Third, some mortgage products are withdrawn or repriced when market conditions change. Waiting too long can mean missing the most competitive deals.
For that reason, many borrowers review their mortgage options well before the fixed rate expires.
Why Professional Advice Can Help
Mortgage deals are not always easy to compare. Every lender has its own rules around affordability, deposits and the types of products it offers.
Because of that, some homeowners speak with a mortgage advisor when their fixed deal is coming to an end.
A good mortgage advisor can look across many different lenders and explain how the available deals compare. For people whose income, job or circumstances have changed since they last arranged a mortgage, that outside view can be useful when deciding what to do next. A whole-of-market mortgage broker can also access a wide range of lenders, which may give borrowers more options to consider.
Planning Ahead for Mortgage Stability
The end of a fixed mortgage deal does not need to be stressful. Most of the time it simply means choosing what to do next.
Looking at mortgage options a few months early gives homeowners more time to compare deals and decide what works best before the current rate finishes.
Rather than letting the loan move straight onto the lender’s Standard Variable Rate, many borrowers use this moment to review their mortgage and see if a better deal is available.
Keeping an eye on rates and understanding how SVR works can help avoid paying more interest than necessary over time.

That rate is often higher than the previous deal and it can change over time.
Can I remortgage before my fixed rate ends?
Yes, many lenders allow borrowers to secure a new mortgage deal three to six months before the fixed rate finishes.
The new deal can then begin as soon as the current fixed term ends.
How much could my mortgage payment increase when the fixed rate ends?
Payments can increase if the mortgage moves onto the lender’s Standard Variable Rate.
How much they rise depends on the size of the loan, how long is left on the mortgage, and how different the SVR is from the previous fixed rate.
