How long should I fix my mortgage for?

How long should I fix my mortgage for in 2025? 

When deciding how long you should fix your mortgage for, there are a few things to consider. First, if you have a low LTV (i.e. you have a high percentage of equity in your property compared to your outstanding mortgage), you could benefit from a fixed-rate mortgage as you could get lower interest rates than someone with a higher LTV. But it's also a good idea to be aware of what's happening with mortgage rates. Right now, a mini price war has emerged between mortgage lenders, with many high street names offering deals sub-4%. It's expected that mortgage rates in general will continue to come down, ending 2025 at an average of 3.63%!

Fixing for two years could protect you from any short-term rate increases while allowing you to remortgage onto hopefully a lower rate in a couple of years' time. However, there's no guarantee rates will drop, and you could have to remortgage to higher rates.

Second, how long do you plan to stay in the property? If this is your forever home or you have a good idea how long you’ll live there, fixing your mortgage could be a smart move. You won’t need to worry about remortgaging or paying fees to port the mortgage to another property.

Third, how much risk can you cope with? We all have our own attitude to risk. Some people feel comfortable taking financial risks if there’s a chance they’ll be better off. Others are risk-averse and don’t sleep soundly at night unless they’re financially secure. Before making a decision, think about how financial uncertainty makes you feel, and if you would be happier knowing what you'll be paying on your mortgage each month, regardless of what's going on in the market.

Navigating a volatile mortgage market can be challenging to do alone, so it’s a good idea to speak to an experienced mortgage broker.

What is the average fixed mortgage interest rate?

Right now, mortgage rates are at their lowest level since June 2024. Currently, the lowest 2-year fixed mortgage rate from our panel of lenders is 4.44%, while the lowest 5-year fixed mortgage rate is 4.29%, and there are even some sub-4% deals available for buyers with large deposits. However, keep in mind that fixed rates are normally much higher for specialist mortgages and longer fixed periods. What rate you could get is also influenced by your eligibility and deposit size or equity.

Is now a good time to fix my mortgage?

Mortgage rates are on a downward trend, and are expected to keep tracking downwards, but gradually. If you're 6 months away from your current deal ending, you can lock in a mortgage deal now to make the most of current rates, then if rates go down further before you remortgage you could reapply. This helps to protect you from rate rises as you'll lock in the lower rate. The same goes for applying for a mortgage - a mortgage offer typically is valid for 3-6 months, but the exact length depends on the lender and other factors. If you want to buy soon, there are also ways to get access to lower mortgage interest rates or get a bigger mortgage.

Sticking with a variable-rate mortgage might also be risky in the current climate. Although the Bank of England has now cut the base rate to 4.25% and should cut it again before the end of the year, if inflation begins to climb again the Bank could raise it again. Every time the Bank of England increases the base rate, rates on variable-rate mortgages will increase too, which will make repayments more expensive.

The Bank of England has kept the base rate high in an attempt to get inflation under control - the target is to get inflation down to 2%. Although inflation is expected to hover above this in 2025, the market is expecting the base rate to be cut at some point over 2025.

Is it better to fix my mortgage for longer?

Fixing your mortgage for longer can give you greater certainty as you'll know exactly what your mortgage repayments will be for the next 5 or 10 years. However, fixing for a longer term normally comes with higher interest rates - although rates for 5 year deals are lower than 2 year deals at the moment.

This is because mortgage lenders don't know what the market will be like in 5 or 10 years' time, so they are taking a risk by allowing you to fix your mortgage for that length of time. To help balance out this risk, they often offer higher interest rates on longer fixed-rate deals than shorter ones. Higher interest rates will also make your monthly repayments more expensive, as you'll have to pay more to your mortgage lender in interest.

The other risk with fixing your mortgage for longer is current mortgage rates could end up being much lower than your fixed rate. This means you will be paying more interest each month in comparison to live interest rates.

While you can switch to a new rate, you might have to pay an early repayment charge (ERC) and possibly a penalty to leave your fixed rate deal early which can be costly.

Should I fix my mortgage for 2 or 5 years?

Whether you should fix your mortgage for 2 or 5 years depends on you and your individual circumstances. Fixing your mortgage for 2 years can give you certainty and stability in the short-term, and can also be the right choice if you only plan on staying in your home for a few years. Plus, if rates decline over the next two years, it means you can then move onto a new rate once your deal ends.

Fixing your mortgage for 5 years can give you certainty over a longer period of time, which can be better if you plan on staying in the property for a long time. However a lot can happen over 5 years, so there is a chance mortgage interest rates could drastically change over that time, which could mean you'll end up paying more interest in comparison to live rates.

Should I fix my mortgage for 10 years?

Fixing your mortgage for 10 years can give you even more protection and peace of mind than fixing for 2 or 5 years, although interest rates are usually higher for longer fixed rate deals. If you know you’ll be staying in your home for a decade or more, or you feel that the years ahead are going to be bumpy, this could be the right option for you.

But if interest rates fall after you’ve fixed your mortgage, you may end up paying more interest than if you’d fixed for a shorter term or stuck with a variable rate. If you find you want to leave before 10 years, you may also have to pay an early repayment charge and potentially a penalty.

What to do if your fixed-rate mortgage ends in 2025?

If your fixed-rate mortgage deal is ending this year, there are a couple of options which could be open to you. One is to do nothing and move onto your lender's Standard Variable Rate (SVR) automatically when your deal ends. SVRs then to be significantly higher than current fixed-rate deals, so this option is likely to cause your repayments to increase. Another option is to remortgage to a new deal with a new provider or to remortgage with your current provider (technically called a product transfer, or product switch). Moving to a part and part or interest-only deal can help you reduce your monthly payments in the short term. If you are struggling to remortgage due to affordability, you could also consider an Income Boost remortgage, which involves adding a loved one onto your mortgage as a guarantor.

What are the pros of fixing your mortgage?

1. Protection against interest rate increases

When you fix your mortgage, you essentially lock yourself into today’s interest rates for a set period of time. It won’t matter whether interest rates go up or down, you’ll keep paying the same amount until your fixed rate period ends. 

2. You may save money on fees

Every time you remortgage your home, you may have to pay fees to do so. For example, some lenders charge an arrangement fee, which can set you back hundreds of pounds. Sticking with the same mortgage for many years will help you reduce the amount you spend on fees. However, if you’re able to remortgage to a better deal, paying the fee can be worth it in the long run, so always seek advice from a mortgage broker.

3. You’re protected from changing criteria

Lenders will sometimes tighten their affordability criteria, making it harder for existing borrowers to remortgage. If you’re locked into a fixed-rate deal, this isn’t something you need to worry about until your fix is over.

If you fall into this category, you could remortgage onto a new deal with your current lender through a product transfer.

4. You’re protected from changing circumstances

Fixed rate mortgages can also protect you if your own circumstances change. Let’s imagine you buy a home when you’re in full-time employment but you become self-employed 6-months after completion. If you’ve not fixed your mortgage, you may struggle to secure a new deal in the near future. This is because lenders often have tighter criteria for self-employed applicants — particularly those who haven’t been working for themselves for long. 

Whereas if you fix your mortgage for 5 years, for example, you won’t need to worry about meeting lenders’ criteria during that period. In this scenario, by the time your fixed rate ends your business will hopefully be well established and you’ll pass lenders’ affordability checks with flying colours. 

Another example is if you want to remortgage or fix your mortgage while pregnant or on maternity leave. It’s possible to get a mortgage when you’re having a baby, but lenders will want to see evidence that you’ll be able to afford the repayments if your income is lower or you have to factor childcare costs into your budget.

You can learn more about this in our guide to getting a mortgage when you’re on maternity leave.

What are the cons of fixing your mortgage?

1. Your monthly payments may be higher

Fixing has so many advantages but it tends to come at a cost. Your monthly payments will often be higher on a fixed-rate mortgage than they would be if you opted for a variable rate. This may sound counterproductive, but you’re essentially paying a premium for stability and protection.

2. You may pay a penalty if you move

If you want to move house 3 years into a 5 year fix, you may have to pay a penalty. Some mortgage deals are portable, meaning you can take them with you to your new home at no extra cost, but others will see you having to pay to exit your fix early.

3. Want to pay your mortgage early? You may face an early repayment charge 

If you get a pay rise, inheritance or lottery win during your mortgage term, you may decide to pay the rest of your mortgage off early. This can save you thousands in interest, but it can result in an early repayment charge (ERC). Most lenders will let you overpay a certain amount each year (often up to 10% of the remaining mortgage balance) at no extra charge. Overpay more than this, and you may have to pay an ERC. You might also have to pay a charge if you’re a joint owner of the property but you’d like to buy the other person out of the house.

Is a fixed-rate mortgage worth it?

Whether a fixed rate mortgage is worth it depends on you, your financial situation and your feelings about money. If you’re someone who likes security and stability, fixing your mortgage can be worth it — even if you end up paying more than you would on a variable rate in the long run. You’ll be able to budget several months in advance and you’ll hopefully sleep soundly at night knowing your mortgage payments won’t fluctuate from one month to the next. For those who are risk-adverse, for this reason a fixed rate mortgage can give you peace of mind. 

But for those who are more comfortable with risk, going onto a variable rate mortgage can be a better option. It can be cheaper in the long run to have a variable rate mortgage, although your monthly payments may fluctuate in the amount you pay month to month. You can go onto a variable rate mortgage, and then choose to fix when mortgage interest rates go down later down the line, securing a lower rate. However, they could also go up in this time period, which is why it depends if you are comfortable taking this risk, and have the cash to cope with the amount you pay each month fluctuating.

FAQs

What happens when my 5-year fixed mortgage ends?

When your fixed mortgage ends, you’ll be moved onto your lender’s standard variable rate (SVR). At this point you might decide to do nothing and pay the SVR, or remortgage to a better deal. It’s a good idea to compare mortgages before choosing a new one. A mortgage broker can help you compare a wide range of mortgage deals from across the market before selecting the right one for you. 

Is it worth it to break a fixed mortgage?

Breaking a fixed mortgage can be expensive. You may have to pay charges to exit your deal early. However, if you’re moving to a better deal and the overall cost of your new mortgage will be lower, this can quickly cover the cost of the fees.  

What is the best term to fix a mortgage?

The best mortgage term for one person won’t be the best term for another. To find out which fixed term is right for you, it’s a good idea to talk to a mortgage broker.
