If you already have a mortgage — or you’re about to take one out — you might be wondering:
“Can I change the length of my mortgage?”
The short answer is yes, in many cases you can. But whether it’s the right thing to do depends on your personal situation, your finances, and your long-term plans.
In this guide, we’ll explain what changing your mortgage term means, why people do it, how it works, and what to think about before making a decision — all in plain English.
What Is a Mortgage Term?
Your mortgage term is simply how long you agree to repay your mortgage.
Common mortgage terms include:
- 20 years
- 25 years
- 30 years
- 35 years
At the end of the term, your mortgage should be fully repaid.
Changing your term means either shortening it or extending it — and both options have different benefits and drawbacks.
Can I Change the Term of My Mortgage?
Yes, many homeowners can change the term of their mortgage, but it usually requires:
- A lender’s approval
- An affordability check
- Sometimes a new mortgage application
You can usually change your mortgage term when:
- You remortgage
- You apply for a product switch with your current lender
- You make a formal request to your lender
Each lender has its own rules, so what’s possible for one person may not be possible for another.
Why Would Someone Want to Change Their Mortgage Term?
There are lots of reasons people look at changing their mortgage term. Here are the most common ones.
- To Reduce Monthly Payments
Extending your mortgage term spreads repayments over a longer period, which can reduce your monthly payments.
This can help if:
- Household costs have increased
- You’ve had a change in income
- You want more breathing room each month
However, while monthly payments may be lower, you’ll usually pay more interest overall.
- To Pay the Mortgage Off Faster
Shortening your mortgage term increases monthly payments, but reduces how long you’re in debt.
People often do this if:
- Their income has increased
- They want to be mortgage-free sooner
- They’re planning for retirement
A shorter term usually means less interest paid over time, but higher monthly costs.

- Becoming self-employed
Your mortgage should fit your life — not the other way around.
How Does Changing the Term Affect My Mortgage?
Changing your mortgage term affects two main things:
Monthly Repayments
- Longer term = lower monthly payments
- Shorter term = higher monthly payments
Total Amount Paid
- Longer term = more interest overall
- Shorter term = less interest overall
It’s a balancing act between affordability now and cost over the long term.
Can I Change My Mortgage Term Without Remortgaging?
Sometimes, yes.
Some lenders allow you to change your mortgage term:
- During a product switch
- Mid-deal (subject to checks)
However:
- Not all lenders allow this
- Early repayment charges may apply
- Affordability will still be assessed
This is where advice can be especially useful, as the small print really matters.
Is There an Age Limit When Changing a Mortgage Term?
Most lenders have a maximum age at which the mortgage must end, often between 70 and 85, depending on the lender.
If extending your term pushes the end date beyond this age, lenders may:
- Decline the request
- Ask for proof of retirement income
- Offer a shorter extension
Planning ahead is important, especially if retirement is on the horizon.
Will I Need a New Affordability Check?
In most cases, yes.
Lenders will usually reassess:
- Your income
- Your outgoings
- Your credit history
Even if you’re staying with the same lender, affordability rules may have changed since you first took your mortgage out.
Should I Extend or Shorten My Mortgage Term?
There’s no one-size-fits-all answer.
Extending your term might suit you if:
- You need lower monthly payments
- You want financial flexibility
Shortening your term might suit you if:
- You can comfortably afford higher payments
- You want to reduce interest and clear the mortgage sooner
The right choice depends on your goals, not just the numbers.
