2-Year vs 5-Year Fixed Rate Mortgage: How to Choose
The choice between a 2-year and 5-year fixed rate mortgage is one of the most common decisions UK borrowers face, whether they’re taking their first mortgage or remortgaging onto a new deal. The right answer depends less on where you think rates are going, and more on your own situation: how long you plan to stay in the property, how much certainty you want, and how much flexibility you might need if life changes.
Here’s what actually separates the two, how fees and early repayment charges factor in, and how to work out which fixed term is likely to suit you best.
What’s the difference between a 2-year and 5-year fixed rate mortgage?
The main difference between a 2-year and a 5-year fixed rate mortgage is the length of time your interest rate and monthly payments stay the same.
A 2-year fix lets you review your mortgage and switch to a new deal sooner if interest rates drop or your circumstances change. A 5-year fix locks your rate for 60 months, protecting you from rising interest rates for a longer period and giving more predictable long-term budgeting.
Historically, 2-year fixes have tended to be cheaper than 5-year fixes, though this varies with market conditions and can invert entirely. Leaving either deal early usually triggers an early repayment charge, but these penalties are often higher and apply for longer on a 5-year fix.
Should you fix your mortgage for 2 or 5 years?
Choose a 2-year fix if you expect interest rates to fall or plan to move soon. Choose a 5-year fix if you value long-term budget stability and want to avoid remortgaging fees and early exit charges for longer.
A 2-year fix works well when:
| You expect market rates to drop and want the option to remortgage sooner | |
| You plan to sell or move within a couple of years and want to minimise early repayment charges | |
| Your circumstances are changing, new job, growing family, considering relocation | |
| You want to test how comfortable your budget is at the current rate before committing longer | |
A 5-year fix works well when:
| You want the exact same monthly payment for the next five years | |
| You're happy where you are and have no plans to move | |
| You want to avoid the cost and hassle of remortgaging every two years | |
| You'd rather have certainty than risk paying more if rates rise | |
How much does today’s interest rate matter when choosing a fixed term?
Today’s rates set the baseline for your immediate monthly costs, but the decision depends more on where you think rates will go next. It’s a balance between short-term savings and long-term certainty.
When 2-year rates are higher than 5-year rates, it usually means markets expect interest rates to fall. Today’s higher 2-year rate might tempt you into the cheaper 5-year deal. But if rates drop sharply in 18 months, locking into that 5-year deal means you miss out on the lower future rates.
When 5-year rates are higher than 2-year rates, it usually means markets expect rates to stay stable or rise. Choosing the lower 2-year rate saves you money today, but you could face much higher rates when you need to remortgage in two years.
There’s no perfect answer either way, the shape of the market at the point you’re borrowing changes which is the more comfortable bet.
What would happen to your monthly payments when a 2-year fix ends?
When your 2-year fixed rate ends, your monthly payments will change depending on where market rates have moved and what new deal you choose.
If you do nothing, your lender will move you onto their standard variable rate (SVR), which is almost always much higher than your fixed rate, so payments usually jump significantly.
If you remortgage to a new fixed deal:
- If rates are higher than they were two years ago, your new monthly payment will also be higher than your previous deal
- If rates have fallen, you can lock in a cheaper deal, and your monthly payments will go down
Some borrowers move onto a variable rate temporarily if they expect rates to keep falling, though SVRs generally remain expensive as a long-term option.
How could early repayment charges affect the decision?
Early repayment charges (ERCs), fees lenders apply for leaving a deal before the fixed term ends, make a 5-year fix less flexible than a 2-year fix if your circumstances might change.
On a 2-year fixed mortgage, the penalty window is short. You’re free to switch to a new deal or move house without penalty sooner. If interest rates drop or your job changes in year three, you can act without triggering an ERC.
On a 5-year fixed mortgage, the lock-in period is long. ERCs often start high, sometimes 5% of the balance in Year 1, and drop steadily each year through the fix. If you need to break the deal early, that cost can run into thousands of pounds.
The trade-off is straightforward: a 5-year fix gives you certainty, but you pay for that certainty in reduced flexibility.
Should the decision be based on the rate outlook?
Your choice between a 2-year and 5-year fix can factor in the rate outlook, but it shouldn’t be the only thing you consider. Personal factors usually matter more.
How long you plan to stay in the property, whether you’re likely to move for work, how comfortable you are with a payment change in two years’ time, and how important predictability is to your budget, these are almost always more important than trying to time the market.
Why is trying to predict future mortgage rates a risky way to choose?
Trying to predict future mortgage rates is risky because rates are genuinely unpredictable, and guessing wrong can force you to remortgage onto a more expensive market or pay repeated fees sooner than expected.
No one can reliably forecast inflation, global events or central bank decisions. Choosing a 2-year fix because you assume rates will drop means you face higher costs if inflation stays stubborn or rates rise instead. A 2-year fix also forces you to go back to the market twice as often, so arrangement and legal fees repeat sooner.
Choosing purely on a rate prediction also ignores your actual life timeline, whether you plan to move house, change jobs, have children, or take on other financial commitments within the next five years. Those factors are usually far more reliable to base a decision on than any rate forecast.
What fees and remortgaging costs should you include in your comparison?
The core fees to compare are:
| Arrangement fee: Usually the largest. Lower interest rates often come with higher arrangement fees. Check whether you can add it to the loan or need to pay it upfront. | |
| Booking fee: A small, non-refundable fee some lenders charge just to reserve the rate. | |
| Valuation fee: Some lenders charge to assess the property's market value; others include it for free. | |
| Legal or conveyancing fees: Cover the solicitor's work to transfer the deeds. Many lenders offer free standard legal work on remortgages, which reduces this cost significantly. | |
When might a 2-year fix better suit your circumstances?
A 2-year fixed mortgage best suits you if you plan to move or change your financial situation soon, or if you expect interest rates to drop in the near future.
It works well when:
-
You have short-term plans (moving, job change, family change)
-
You expect rates to fall and want the option to capture that
-
You want lower initial costs, if the 2-year rate is currently cheaper
-
You want to test how a mortgage payment fits your budget before committing longer
The risks to be aware of are:
-
More frequent remortgaging, and the fees that come with it
-
The possibility of rates rising by the time you need to remortgage
When might a 5-year fix better suit your circumstances?
A 5-year fixed mortgage best suits someone who wants predictable monthly payments and long-term budget stability.
It works well when:
- You want budget certainty over a longer period
-
You want to avoid the repeated fees and admin of remortgaging every two years
-
You’re planning to stay in the property for the medium to long term
-
You’d rather lock in a rate you’re comfortable with than risk what the market does next
The situations to be more cautious about are:
-
If you’re expecting rates to fall significantly, a 5-year fix locks you out of that saving
-
If you might move in the short term, the early repayment charges can be costly

Frequently Asked Questions
Is it better to fix for 2 or 5 years?
Neither is universally better, it depends on your plans, your budget, and how much certainty matters to you. A 2-year fix gives flexibility and the chance to capture falling rates. A 5-year fix gives longer-term certainty and fewer remortgaging costs.
Can I remortgage before my 5-year fix ends?
Yes, but you'll usually pay an early repayment charge, typically a percentage of your outstanding balance, which drops each year of the fix. Whether it's worth paying the ERC to switch depends on how much you'd save on the new rate.
What about 3-year or 10-year fixed rate mortgages?
Some lenders offer 3-year fixes as a middle ground, though the market is smaller. 10-year fixes exist but often carry higher rates and longer ERC windows. Both are worth considering in the right circumstances.
Can I overpay on both 2-year and 5-year fixed mortgages?
Yes. Most lenders allow overpayments of up to 10% of your outstanding balance each year without triggering an ERC. This applies on both 2-year and 5-year fixes.
What is a tracker mortgage, and how does it compare?
A tracker mortgage follows the Bank of England base rate plus a set margin. Your payments move with base rate changes rather than being locked. Trackers can be worth considering when rates are expected to fall, though there's no certainty on what future payments will look like.
How early can I lock in a new deal before my current fix ends?
Most lenders allow you to secure a new deal up to six months before your current one expires. This is usually a good idea, because it protects you against rate rises without locking you in early, you can normally still switch if a better rate appears before completion.
