Mortgage Term
Also known as: Mortgage length
In simple terms
The mortgage term is how long you have to pay back your mortgage — often 25 years, though it can be shorter or longer. A longer term lowers monthly payments but adds to the total interest.

What does mortgage term mean?
The mortgage term is the full period over which you agree to repay the loan — for example 25, 30 or 35 years. It is different from the deal period (such as a two- or five-year fix), which is just the current rate arrangement sitting inside the overall term.
On a repayment mortgage, the term is set so that regular payments clear the whole balance by the end. On an interest-only mortgage, the term sets when the full capital must be repaid by other means.
How the mortgage term works
The longer the term, the more months there are to spread the repayments over, so each monthly payment is smaller. But because interest is charged for longer, a longer term usually means you pay considerably more interest in total.
You can often change the term when you remortgage — shortening it to clear the debt sooner, or lengthening it to ease monthly payments. Lenders also apply maximum age limits, which can cap how long a term they will offer.
How could this affect me?
Choosing a term is a balance between what you can afford each month and what you pay overall. Stretching the term can make a home affordable now but adds thousands in interest across the life of the loan.
Overpaying, where your deal allows it, effectively shortens the term and cuts total interest — a useful lever if your income improves over time.
Things to watch out for
- A longer term lowers monthly payments but can add many thousands of pounds in total interest.
- The deal period (e.g. a 5-year fix) is not the same as the mortgage term — do not confuse the two.
- Lender maximum-age rules can limit how long a term you are offered, especially later in life.
- Extending the term to cut payments is a real cost, not a free fix — treat it carefully.
