Fix for 2 Years or 5 Years in 2026: How to Decide
Most UK fixed-rate mortgages are sold as 2-year or 5-year products. Three-year, seven-year, and ten-year fixes exist but are far less common, and the decision most borrowers actually face at application or remortgage time comes down to these two. Each commits you to a particular monthly payment for a particular period, and to a particular date in the future when you will need to make this decision again. The difference between a 2-year and a 5-year fix is not just the rate. It is the length of your commitment, the cost of exiting early, and how long you go before revisiting the market.
This article does not tell you which to pick. It explains what each choice commits you to, the variables that tend to make one more or less appropriate for different situations, and the questions worth taking to a qualified broker before you decide.

How fixed-rate mortgages actually work
What the fix locks in
A fixed-rate mortgage locks the interest rate for the agreed term. For a repayment mortgage with no overpayments, the monthly payment is also constant throughout the fix, because the rate and the outstanding balance together determine the payment and neither changes unexpectedly. For an interest-only mortgage, the monthly payment is also fixed, but no capital is being repaid.
What the fix does not lock in is what happens afterwards. When the fixed term ends, the borrower either moves onto a new deal or rolls onto the lender’s Standard Variable Rate (SVR). The fix period is a window of payment certainty. What comes after that window is a separate question.
Early repayment charges during the fix
Leaving a fixed-rate mortgage before the term ends typically triggers an Early Repayment Charge (ERC). ERCs are expressed as a percentage of the outstanding balance, and they vary by product and lender. A common structure is a higher percentage in the early years of the fix that tapers down as the term progresses. On a 5-year fix, for example, an ERC structure might run 5% in year one, 4% in year two, 3% in year three, and so on. On a 2-year fix, the charges are typically smaller in absolute terms because the window is shorter.
The ERC applies in several situations: remortgaging to a different lender before the fix ends, paying off the mortgage in full, or in some cases selling the property if the mortgage cannot be ported. Most fixed-rate products allow overpayments of up to 10% of the outstanding balance per year without triggering an ERC. Exceeding that limit does.
What happens when the fix ends
At the end of the fixed term, the lender moves the borrower onto its SVR unless the borrower has arranged a new deal. The gap between SVR and fixed rates is consistently large, which makes the end-of-fix date a meaningful financial planning event. A borrower who does nothing at the end of a fix and rolls onto the SVR for several months will typically pay significantly more per month than they would on a new fixed deal.
Most lenders allow borrowers to lock in a new rate three to six months before the current fix ends, with no ERC on the existing product because the switch is timed to the end of the term. Starting that process early avoids any gap on the SVR.
The trade-offs of a 2-year fix
What 2 years of certainty covers
A 2-year fix provides payment certainty for 24 months. For a borrower completing a purchase or remortgage in April 2026, the fix runs to around April 2028. Within that window, the rate and monthly payment do not change regardless of what happens to the Bank of England base rate or wider mortgage market.
The arrangement fee structure and headline rate on a 2-year fix tend to be broadly comparable to 5-year equivalents, though which is marginally cheaper varies at any given time depending on the shape of the market. In April 2026, 2-year and 5-year averages across the market sit within a few basis points of each other at most LTV bands.
When 2-year fixes tend to suit a borrower
Borrowers who expect their circumstances to change within two to three years often find 2-year fixes worth considering. Situations that commonly factor in include a planned move, a period of parental leave that will affect income calculations at remortgage time, a career change, or a property purchase where the borrower plans to sell within a few years. A shorter fix reduces the ERC exposure if plans change and the mortgage needs to be exited or restructured.
Borrowers who are comfortable revisiting the mortgage market regularly and who want the ability to respond to whatever product landscape exists in two years may also find the shorter term suits their approach.
What the borrower is exposed to
Choosing a 2-year fix means accepting that in two years’ time, the borrower will need to remortgage onto whatever is available then. The rate could be higher, lower, or roughly the same as today. That outcome is unknown at the point of choosing. The 2-year fix does not protect against an unfavourable rate environment at renewal, nor does it lock the borrower out of a favourable one. It simply defers the decision.
There are also recurring costs to factor in. Each remortgage typically involves an arrangement fee, and potentially legal and valuation costs, depending on whether the borrower stays with the same lender or moves. Over the life of a mortgage, choosing 2-year fixes means going through this process more frequently than with longer terms.
The trade-offs of a 5-year fix
What 5 years of certainty covers
A 5-year fix provides payment certainty for 60 months. For a borrower completing in April 2026, the fix runs to around April 2031. Within that window, neither rate changes nor market movements affect the monthly payment. For households where predictable outgoings matter for budgeting, this extended window removes a significant variable.
When 5-year fixes tend to suit a borrower
Borrowers with stable circumstances and no expectation of significant change tend to find 5-year fixes worth considering. This includes those who are settled in a property they plan to stay in, those whose income is stable and unlikely to require restructuring the mortgage in the near term, and those who place a high value on not having to revisit the remortgage process for an extended period.
The fewer product fee cycles also have a practical effect over time. A borrower who takes a 5-year fix instead of two consecutive 2-year fixes avoids one set of arrangement fees and one round of legal and valuation costs, which can amount to several hundred to a couple of thousand pounds depending on the products involved.
What the borrower commits to
A 5-year fix is a longer commitment on both sides. The ERC applies for the full term, typically tapering but present throughout. A borrower who needs to exit the mortgage in year three of a 5-year fix faces a larger ERC than they would in year three of a 2-year fix that has already ended and been renewed.
Life can change in five years. A borrower who is confident about their circumstances today may face a job change, relationship change, or relocation within the fix period that makes flexibility desirable. Some fixed-rate mortgages are portable, meaning the deal can be transferred to a new property. But portability is subject to lender approval at the time of the move and is not guaranteed. A broker can clarify the porting terms of any specific product.
The variables that matter for your situation
The mechanics of 2-year and 5-year fixes are the same for every borrower. What differs is how those mechanics interact with individual circumstances. The following are the variables worth working through before speaking to a broker.
How long you will be in the property
A borrower planning to sell within two years has a different relationship to ERC risk than one planning to stay for ten. Even where a mortgage is portable, the transfer to a new property is not automatic and requires lender approval at the time. If the move cannot be completed within the fix period, or if the porting application is declined, the ERC applies. Borrowers with a high probability of moving within the fix period are typically more exposed to ERC costs on a longer fix.
How stable your circumstances are
Income changes, employment changes, parental leave, and significant life events can all affect what a borrower needs from their mortgage. Someone expecting a substantial income change within two years may find it harder to remortgage onto competitive terms at that point, depending on how affordability assessments are applied at the time. A longer fix defers that reassessment but also locks in the current structure for longer. Use our property affordability calculator to understand the income multiple that applies to your situation.
Your appetite for payment certainty
Some households budget tightly and need to know exactly what their mortgage will cost each month for the foreseeable future. Others can absorb variation in their monthly outgoings without disruption. A 5-year fix eliminates payment variation for a longer period. A 2-year fix reintroduces it sooner. This is a practical question about how much uncertainty is comfortable to live with, not purely a financial one.
Total cost versus headline rate
The headline rate is only part of the cost comparison. Arrangement fees, valuation fees, and legal costs all form part of the true cost of a mortgage product. A 2-year fix at a rate marginally lower than a 5-year equivalent may end up costing more over the same period once fees are included, particularly if the loan size is smaller. The calculation is straightforward: total interest paid over the period plus fees, compared across both products. A broker can run this for your specific loan size and the products available to you.
Overpayment plans
Most fixed-rate mortgages allow overpayments of up to 10% of the outstanding balance per year without ERC. A borrower planning regular or lump-sum overpayments above that limit would need to check the terms of each product they are considering, since exceeding the limit triggers an ERC charge regardless of how far into the fix they are. If overpayments are likely to be substantial, this is worth factoring into the product comparison.
Worked examples: how the mechanics play out
The rates and figures used in the examples below are illustrative and do not reflect any specific lender or product. They are intended to show how the mechanics work, not to project likely outcomes.
Example 1: A first-time buyer with a 5-year horizon
Property: £350,000. Deposit: £35,000 (10%). Loan: £315,000 over 30 years. Hypothetical 2-year fix at 4.6%. Hypothetical 5-year fix at 4.4%.
At 4.6%, the monthly repayment is approximately £1,609. Over 24 months, total payments come to approximately £38,616. At 4.4%, the monthly repayment is approximately £1,575. Over 24 months, total payments come to approximately £37,800.
The 5-year fix is around £34 cheaper per month during the fix period on these illustrative figures, or approximately £816 over two years. What the borrower pays after the 2-year fix ends depends entirely on the rate environment in two years’ time, which is unknown. This example shows the cost during the fix period only.
Example 2: An ERC scenario
Same loan: £315,000. The borrower needs to exit the mortgage in month 18 due to a job-related relocation. At month 18, the outstanding balance on either product is approximately £305,000 (illustrative, based on standard amortisation at these rates).
- 2-year fix with an illustrative ERC of 1% at month 18: ERC of approximately £3,050.
- 5-year fix with an illustrative ERC of 4% at month 18: ERC of approximately £12,200.
The difference in ERC cost between the two products in this scenario is approximately £9,150. This illustrates why the length of the ERC commitment matters when there is a realistic possibility of needing to exit the mortgage before the term ends. ERC structures vary by lender and product. The specific ERC applicable to any product will be set out in the Key Facts Illustration (KFI) or European Standardised Information Sheet (ESIS).
Example 3: SVR rollover
A borrower on a 2-year fix at 4.6% takes no action at the end of the term and rolls onto their lender’s SVR. Hypothetical SVR: 7.5%. At 4.6%, the monthly payment on £315,000 over 30 years is approximately £1,609. At 7.5%, the same loan produces a monthly payment of approximately £2,118.
That is approximately £509 more per month, or £6,108 per year, on these illustrative figures. The same SVR rollover cost applies at the end of a 5-year fix if the borrower takes no action. The end-of-fix date matters regardless of which term was chosen, and allowing any significant time on the SVR typically carries a material cost.
Questions to take to a broker
Going into a broker conversation with some prepared questions makes the meeting more efficient and the output more useful.
- How long do I plan to stay in this property, and how certain is that?
- What is the realistic probability that my income, family situation, or location changes in the next two to five years?
- What are the overpayment limits on the products I am considering, and do they match what I plan to do?
- What is the full ERC schedule on each product, and at what point does it taper to zero?
- What is the true total cost of each option over the fix period, including arrangement fees and any incentives such as cashback or free legals?
- Is the product portable, and what are the porting conditions if I move during the fix?
- What is this lender’s SVR, and what does my monthly payment look like if I roll onto it for a few months at the end of the term?
- How far in advance can I lock in a renewal rate, and what is the process for doing so?
A fee-free or whole-of-market broker can answer these against the products available to you and your specific circumstances. Credibrate does not provide mortgage advice.
Frequently asked questions
Are 2-year fixes always cheaper than 5-year fixes?
Not always. Which is cheaper depends on the state of the market at the time of application, specifically the shape of the swap rate curve that lenders use to price fixed products. At some points the 2-year is marginally lower; at others the 5-year is. Product fees also affect the total cost. A product with a lower headline rate but a higher arrangement fee may cost more over the fix period than one with a higher rate and lower fee, depending on the loan size. The only reliable way to compare is to calculate the total cost over the fix period for your specific loan amount.
Can I leave a fixed-rate mortgage early?
Yes, but doing so before the fixed term ends will almost always trigger an Early Repayment Charge. ERCs are set out in the product terms and are typically expressed as a percentage of the outstanding balance, often tapering over the course of the fix. The ERC applies whether the borrower is remortgaging to a different lender, selling the property, or paying off the balance in full.
What is the difference between the fix rate and the SVR?
The fix rate is the interest rate that applies during the fixed term. The SVR is the lender’s Standard Variable Rate, which the borrower rolls onto automatically when the fix ends unless they arrange a new deal. SVRs are set by individual lenders and can be changed at the lender’s discretion. In April 2026, the average SVR across UK lenders sits at around 7.15%, materially higher than available fixed-rate deals. The gap varies over time but has consistently been significant.
Can I port a fixed-rate mortgage to a new property?
Most fixed-rate mortgages include a portability feature that allows the deal to be transferred to a new property. However, porting is not automatic. It is subject to the lender re-approving the borrower under current affordability criteria and approving the new property. If the porting application is declined, the ERC applies. The porting conditions for any specific product will be in the product terms, and a broker can clarify what those conditions mean in practice for your circumstances.
Do I have to remortgage with the same lender at the end of my fix?
No. When the fix ends, the borrower is free to remortgage to any lender, subject to normal affordability and eligibility criteria. Staying with the same lender via a product transfer is one option, but comparing the market through a broker typically surfaces alternatives. Product transfers with the same lender often complete faster because no legal or valuation work is required, but the rate may not be the most competitive available.
What are typical ERCs on fixed-rate mortgages?
ERCs vary by product and lender, but commonly range from 1% to 5% of the outstanding balance. On a fix that tapers, the percentage is typically higher in the early years and lower towards the end of the term. The specific ERC schedule for any product will be set out in the KFI or ESIS issued before application. Always check this document rather than relying on general ranges.
Can I overpay during a fix?
Most fixed-rate mortgage products allow overpayments of up to 10% of the outstanding balance per year without an ERC. Exceeding that limit typically triggers a charge on the excess. If you plan to make substantial overpayments, confirm the specific limit on each product you are comparing before committing.
When should I start looking at remortgage options before my fix ends?
Three to six months before the fix end date is a common starting point. Many lenders allow borrowers to lock in a rate up to six months in advance, timed to start when the current fix expires. This means the new deal begins on the day the old one ends, with no gap on the SVR. Starting early also gives time to complete a full remortgage to a new lender if the product transfer rate from the existing lender is not competitive.
Is a longer fix always safer?
It depends on what you mean by safer. A 5-year fix provides payment certainty for longer and removes the risk of needing to remortgage at an unfavourable time. A 2-year fix provides flexibility sooner and reduces the ERC exposure if circumstances change. Neither is inherently safer. They offer different types of certainty and different types of risk. What matters is which set of trade-offs fits the borrower’s specific situation.
Is it better to get advice from a broker or go direct to a lender?
A whole-of-market or large-panel broker has access to products from multiple lenders and can compare the market on your behalf. Going direct to a single lender limits the comparison to that lender’s own products. A broker also provides regulated mortgage advice, meaning the recommendation is assessed against your circumstances and documented. The FCA regulates mortgage advice, and borrowers are entitled to a KFI or ESIS setting out the full terms of any product they are offered before they commit.
