Your mortgage term affects both your monthly repayments and how long it takes to clear your mortgage. When you remortgage, you may be able to adjust that term to better match your budget, repayment plans or wider financial goals.
Extending your term could reduce your monthly payments, while shortening your term could help you repay the mortgage sooner. However, changing your term can also affect affordability, total interest and long-term cost.
Muttuo Mortgages can help you compare remortgage options from over 100 lenders and check how a term change could affect both your monthly payments and the overall cost of your mortgage.
Before you change your mortgage term
✓ A longer term may reduce monthly payments
Spreading your mortgage over more years can lower the monthly cost, but may increase the total interest.
✓ A shorter term may help you repay sooner
Reducing your term can help clear the mortgage faster, but your monthly payments are likely to rise.
✓ Affordability still matters
Lenders will usually check whether the new payment is affordable, especially if you want to shorten the term.
✓ Total cost should be compared
The best option is not always the lowest monthly payment. It is important to check what the change means over the full mortgage term.
What does changing your mortgage term mean?
Changing your mortgage term means adjusting how long you have left to repay your mortgage.
When you remortgage, you may be able to keep the term similar, extend it to lower monthly payments, or shorten it to repay the mortgage sooner. A longer term can make payments more manageable, but may increase total interest. A shorter term can reduce total interest, but usually means higher monthly payments.
The right option depends on your affordability, age, mortgage balance, lender criteria and long-term plans.
Extending or shortening your mortgage term
Changing your mortgage term usually comes down to extending it or shortening it. Each route can help in different ways, but both can affect your monthly payments and long-term costs.
Option 1: Extend your term
Lower monthly payments
Extending your mortgage term spreads the balance over more years, which can reduce your monthly payments and give your budget more breathing room.
This may help if your current payments feel too high or your income and spending have changed. However, you may pay more interest over time, and the mortgage could run later into life.
Option 2: Shorten your term
Repay the mortgage sooner
Shortening your mortgage term means paying the balance back over fewer years. This usually increases monthly payments, but can reduce the total interest you pay.
This may help if your income has increased or you want to clear the mortgage faster. However, your monthly payments may rise, and you could have less spare income each month.
How changing your term could work in practice
Changing your mortgage term can affect the monthly payment and the total amount of interest you pay. The same mortgage balance can look very different depending on how long you choose to repay it.
01 Your current mortgage position
Mortgage balance: £220,000
Current remaining term: 24 years
Comparison interest rate: 4.75%
Estimated monthly payment: £1,282
Estimated interest over the term: £149,116
This gives you a starting point for comparing how a longer or shorter term could affect your repayments.
02 You extend the term
New mortgage term: 30 years
Estimated monthly payment: £1,148
Estimated interest over the term: £193,145
Extending the term could reduce the monthly payment by around £134, because the mortgage is spread over more years. However, in this example, the total interest could increase by around £44,029.
03 You shorten the term
New mortgage term: 18 years
Estimated monthly payment: £1,517
Estimated interest over the term: £107,701
Shortening the term could increase the monthly payment by around £235, but it may help you repay the mortgage sooner. In this example, the total interest could be reduced by around £41,415.
What this comparison shows
This example shows how the same mortgage balance can lead to different monthly payments and interest costs, depending on the term you choose.
✓ Extending the term may lower monthly payments, but increase total interest
✓ Shortening the term may increase monthly payments, but reduce total interest
✓ The right term should balance affordability now with long-term cost
The best option is not always the lowest monthly payment. It is the term that gives you the right balance between affordability today and cost over time.
Illustration only: Figures assume the same interest rate across each term. Actual payments and total interest depend on your rate, balance, fees, repayment type, lender criteria and circumstances.

Why changing your term affects total interest
Your mortgage term affects how long you pay interest for. Even if the interest rate stays the same, changing the term can change the overall cost of the mortgage.
A longer term usually reduces the monthly payment because the balance is spread over more years. However, you may pay interest for longer, which can increase the total amount paid back.
A shorter term usually increases the monthly payment because the balance is repaid faster. This may mean you pay less interest overall because the mortgage is cleared sooner.
What to check before changing your term
- Monthly affordability
- Total interest over the term
- Whether the term runs into later life
- Overpayment flexibility and early repayment charges
The lowest monthly payment is not always the lowest-cost option. If you extend your term, the key question is whether the short-term savings are worth the extra interest over time.
What lenders may check
If you want to change your mortgage term when remortgaging, lenders will usually check whether the new payment is affordable and whether the term fits their criteria.
Check
What it means
Income and spending
Whether the new monthly payment is affordable alongside your regular commitments.
Age and retirement plans
Whether the mortgage will remain affordable if the term runs into later life.
Mortgage balance
How much the payment changes if the term is extended or shortened.
Credit profile
Whether missed payments, credit usage or recent borrowing affect your options.
Loan-to-value
How your property value and balance affect the deals you may qualify for.
Size of the term change
Whether the change is small, significant or extends the mortgage into retirement.
Even if changing your term seems straightforward, the lender still needs to check that the new mortgage is affordable and fits their criteria.
Other options to compare before changing your term
Changing your mortgage term is not the only way to adjust your monthly payments. Depending on what you want to achieve, there may be other routes to compare before you decide.
Option 1: Remortgage
Switch to a new rate
A different mortgage rate could change your monthly payment without changing the length of your mortgage.
This may be worth checking if your current deal is ending or if you want to compare wider remortgage options.
Option 2: Overpayments
Make overpayments
If your goal is to repay sooner, overpayments may give you more flexibility than committing to a shorter term.
Before doing this, check whether your mortgage has overpayment limits or early repayment charges.
Option 3: Repayment type
Review repayment type
Some borrowers may consider interest-only or part-and-part options, although these come with specific risks and lender criteria.
This route needs careful advice because you must have a credible repayment plan.
Option 4: Product transfer
Consider a product transfer
If you want to stay with your current lender, a product transfer may let you move onto a new deal without a full remortgage.
However, it is still worth comparing the rate, fees and total cost against wider options.
The right route depends on whether you want to lower payments, repay faster, improve flexibility or reduce long-term cost.
Not sure which route fits your budget?
Compare term changes, remortgage options and product transfer routes before you decide.
Benefits and trade-offs of changing your mortgage term
Changing your mortgage term can help you reshape your mortgage around your budget or repayment goals. However, it can also affect how much interest you pay and how flexible your mortgage feels later.
Benefits
Lower monthly payments
Extending your mortgage term can reduce the monthly payment by spreading the balance over more years.
Repay the mortgage sooner
Shortening your term can help you clear the mortgage faster and may reduce the total interest paid.
Match your mortgage to your plans
A term change can help your mortgage better reflect changes in income, spending, family plans or retirement goals.
Trade-offs
You may pay more interest over time
A longer term can make monthly payments lower, but you may pay interest for more years.
Monthly payments could rise
A shorter term usually means higher monthly payments, which need to remain affordable.
Your options may be limited
Lender age limits, affordability checks, retirement plans and mortgage criteria can affect whether a term change is available.

Frequently asked questions about remortgaging to change your term
Use these FAQs to answer common questions about extending, shortening and reviewing your mortgage term.
Can I change my mortgage term when I remortgage?
Yes, you may be able to change your mortgage term when you remortgage.
Changing your term means adjusting how long your mortgage is set to run. You may want to extend the term to reduce monthly payments, or shorten it to repay the mortgage sooner.
Whether this is available depends on your lender, age, affordability, mortgage balance, income and wider circumstances.
What happens if I extend my mortgage term?
Extending your mortgage term can reduce your monthly payments, but may increase the total interest paid.
A longer term spreads the mortgage balance over more years. This can make the monthly payment more manageable, which may help if your budget is under pressure.
However, because the mortgage runs for longer, you may pay interest for more years. That means the total cost of the mortgage could increase, even if the monthly payment falls.
What happens if I shorten my mortgage term?
Shortening your mortgage term can help you repay your mortgage sooner, but your monthly payments are likely to rise.
A shorter term means you are repaying the balance over fewer years. This can reduce the amount of interest you pay overall, but the higher monthly payment needs to be affordable.
Lenders will usually check your income, spending and commitments before agreeing to a shorter term.
Is it better to extend or shorten my mortgage term?
It depends on whether your priority is lower monthly payments or reducing long-term costs.
Extending your term may suit you if you need more breathing room in your monthly budget. Shortening your term may suit you if you can afford higher payments and want to repay the mortgage faster.
The right option depends on your income, affordability, age, mortgage balance, future plans and how much flexibility you need.
Will changing my mortgage term affect affordability checks?
Yes, changing your term can affect how lenders assess affordability.
If you shorten your term, the monthly payment is likely to increase, so the lender needs to check whether the higher payment is affordable.
If you extend your term, the payment may reduce, but the lender may still consider your age, retirement plans and whether the mortgage runs too far into later life.
Can I change my term without remortgaging?
Sometimes, but it depends on your current lender and mortgage deal.
Your existing lender may allow a term change, product transfer or other adjustment without a full remortgage. However, this is not guaranteed and may still involve affordability checks.
It is worth comparing this against remortgage options, especially if your current deal is ending or you want to check whether another lender could offer a more suitable route.
Could overpayments be better than shortening my term?
Overpayments may give you more flexibility than committing to a shorter term.
If your goal is to repay the mortgage sooner, overpayments could help reduce the balance while keeping your required monthly payment lower. This may suit borrowers who want flexibility rather than a fixed higher payment.
However, some mortgages have overpayment limits or early repayment charges, so it is important to check the rules of your deal first.
When should I review my mortgage term?
It is usually worth reviewing your mortgage term before your current deal ends or when your budget, income or plans change.
A term review can be useful if your payments feel too high, your income has increased, you want to repay faster, or your mortgage may run into later life.
Starting early gives you more time to compare options and understand how different term lengths could affect both your monthly payment and total cost.
