Two-year fixed-rate mortgages ending: why you must avoid the SVR trap

Over a million UK homeowners coming off two-year fixed-rate mortgages risk paying thousands of pounds more each year if they slip onto their lender’s standard variable rate without acting. The gap between the average SVR and the best available fixed rates is stark, and the cost of doing nothing is measurable.

Why so many fixed-rate deals are ending now
Many borrowers who took out two-year fixes in late 2023 and 2024 chose shorter terms deliberately, betting that interest rates would fall and they could remortgage onto something cheaper. That prediction has largely come true, but it also means there is now a significant wave of deals expiring at roughly the same time. According to UK Finance, around 1.6 million fixed-rate mortgages expired across 2025, with a further 1.8 million due to expire in 2026.
The current cohort facing expiry includes 122,526 first-time buyers, 111,349 home movers, 690,738 homeowners who previously remortgaged with their current provider, and 122,832 who remortgaged with a new provider, according to research from Compare the Market. That is a broad cross-section of borrowers, not a niche group, and many of them will be facing their first experience of remortgaging under pressure.
The SVR trap: what “doing nothing” actually costs
If you reach the end of your fixed term and take no action, your lender will move you automatically onto its standard variable rate. Based on an average mortgage debt of £200,250, that means monthly payments could jump to £1,432, an increase of £283 per month compared to your previous two-year fix. Over a full year, that translates to paying £17,184 rather than £13,788 — more than £3,000 extra annually.
The average SVR across lenders currently stands at 7.13%, according to Moneyfacts. By contrast, Bank of England figures show the average two-year fixed rate in July 2025 was 4.79%. That is a substantial difference, and it compounds quickly on a typical mortgage balance. UK Finance estimates that 540,000 households are already sitting on their lender’s SVR, so the problem is not theoretical.
Switching from an SVR to a new two-year fix could reduce monthly repayments by up to £286 per month, or £3,432 across a year. That is a meaningful sum for most households, particularly at a time when most budgets remain tight.
What the current rate environment looks like
The encouraging news is that mortgage rates have generally been falling since 2024 in line with Bank of England base rate reductions. Lenders are actively competing for remortgage business, and rates have continued to edge down in recent weeks. Nationwide has cut mortgage rates twice this month, with the latest round reducing rates by up to 0.15 percentage points across two, three, and five-year fixed products. Its lowest rate now sits at 4.48% on a 60% loan-to-value deal, with a £1,499 fee attached. HSBC UK has also reduced selected rates by up to 0.20%.
These cuts matter because even a small reduction in the rate you secure can save you hundreds of pounds over the life of a deal. It is worth noting that the lowest headline rates often come with arrangement fees, so the total cost comparison needs to account for those fees, not just the rate itself. A slightly higher rate with no fee can sometimes work out cheaper depending on your loan size and term.
How to act before your deal expires
You do not need to wait until your fixed rate ends to start the remortgage process. Most lenders allow you to lock in a new rate up to six months before your current deal expires, which means if your mortgage ends any time before early 2026, you can start looking now.
Sajni Shah, money expert at Compare the Market, puts it plainly: “Shopping around to compare mortgages from different lenders is one of the simplest ways to see what’s available and find a deal suited to individual circumstances.”
Locking in a rate early does not mean you are committed to it indefinitely. If a better deal becomes available before your current term ends, you can often switch to it, particularly if you have not yet completed. This means the main risk of starting early is administrative rather than financial.
A mortgage broker can be worth the time investment here, particularly if your circumstances have changed since you last remortgaged. Brokers have access to deals not always visible on comparison sites, and they can assess the full cost picture including fees, overpayment options, and exit charges on your current deal.
What to check before you remortgage
Before approaching a lender or broker, it helps to have a clear picture of a few key figures. Your outstanding mortgage balance and your current property value together determine your loan-to-value ratio, which directly affects which rate bands you can access. A lower LTV generally unlocks better rates, so if you have been making overpayments or property values in your area have risen, you might qualify for a more competitive tier than when you last remortgaged.
You should also check your credit file before applying, since lenders will run a full credit check as part of any new application. Any errors on your record can slow the process or affect the rates you are offered. Services such as Experian, Equifax, and TransUnion all offer free report access.
Finally, be clear on whether your current deal carries an early repayment charge. Most two-year fixes do, but that charge typically drops to zero on or after the end date. If you are within a few weeks of your deal ending and have not yet arranged a new one, it may still be worth a short spell on the SVR rather than incurring a large exit fee, though you should calculate the numbers carefully.
What this means for you
The core message from the data is simple: the SVR is expensive, the alternatives are considerably cheaper, and the window to act is now. If your fixed deal ends within the next six months, the time to start looking at remortgage options is this week, not the week your deal expires.
Waiting costs money. The average homeowner who slips onto an SVR and stays there for a year before remortgaging is paying more than £3,000 extra for the privilege of doing nothing. That is money that could be directed towards overpayments, home improvements, or simply kept in your pocket.
Verdict
This is one of the more clear-cut personal finance decisions available to homeowners right now. The rate gap between SVRs and competitive fixed deals is wide, the market is moving in borrowers’ favour, and the process of locking in a new rate early is straightforward. Start comparing deals now, get your figures together, and consider speaking to a broker if your circumstances are at all complicated.
Frequently asked questions
How long before my mortgage ends should I start looking at remortgage deals?
Most lenders let you lock in a new rate up to six months before your current deal expires. Starting early gives you time to compare properly and also means you can switch to a better deal if rates fall further before your end date.
Will I pay an early repayment charge if I remortgage before my fixed term ends?
Almost certainly yes, if you complete the new mortgage before your current deal’s end date. Charges vary by lender but can be significant. Most people time their remortgage to complete on or after the end date to avoid this. Starting the application early does not trigger the charge.
What is an SVR and why is it usually more expensive?
A standard variable rate is the default rate your lender charges once a fixed or tracker deal ends. Unlike fixed rates, it is not tied to a competitive market rate, and lenders set it independently. It tends to be considerably higher than what is available to new or remortgaging customers.
Does it matter if my property value has changed since I last mortgaged?
Yes. Your loan-to-value ratio determines which rate bands you can access. If your property has increased in value or you have reduced your balance through overpayments, you may qualify for a lower LTV bracket and a better rate. It is worth getting an up-to-date valuation before you apply.
Should I use a broker or go directly to a lender?
Both are valid, but a broker can compare deals across multiple lenders and access some products not available directly. If your situation is straightforward and you are comfortable comparing deals yourself, going direct is fine. If your income, credit history, or property type is at all unusual, a broker is likely worth the time.
The rate environment is as favourable as it has been for several years, and the tools to compare and secure a new deal are readily available. Acting sooner rather than later is the only sensible move.
