Remortgaging allows you to realign your home loan with your long-term financial objectives. Borrowers can change the duration of their agreement when switching to a new deal, whether staying with an existing lender or moving to a new provider. When you change your mortgage term, it will affect your monthly repayments and how much interest you have to pay, which could go up or down depending on how your mortgage term changes and how your credit and other factors affect the deals you are offered.

It is important to carefully consider whether the deal you have been offered is right for you. At JMW, our remortgaging solicitors carry out the legal steps involved in the process of remortgaging, whether you are switching to a new lender or staying with the same provider. Here, we explain the ways that changing your mortgage term could affect affordability and what is involved in changing the term of your mortgage when you secure a new deal.

How Changing Your Mortgage Term Works

Changing the loan duration involves rewriting the repayment plan for the outstanding balance, which occurs during the transition between mortgage deals. Lenders will perform affordability checks to establish that the revised monthly mortgage payments are sustainable alongside your other outgoings, so you should perform your own calculations to make sure the terms are affordable and likely to be approved.

During a remortgage, the new lender evaluates the remaining length of the agreement and the outstanding balance. They calculate monthly outgoings based on the adjusted timeline, and this sometimes enables buyers to lower their mortgage repayments, which in turn could help you to address other financial priorities such as debt consolidation.

Extending Your Mortgage Term

Extending the loan duration is a way to lower monthly outgoings. By spreading the debt over a longer repayment period, you reduce the immediate pressure on your budget. This is particularly useful if interest rates have climbed or your financial situation requires more liquidity.

However, while the new monthly commitment is lower, borrowers must recognise that this choice impacts long-term costs. A lower monthly payment amount means that you are paying off less of the outstanding mortgage balance, which allows interest to accrue and could lead to you paying significantly more over time. As such, while extending the repayment period can solve immediate cash flow issues, you will not always save money with this approach unless you are comfortable with overpayments or the total amount you borrow is much less than your original mortgage was worth.

Another factor is that lenders consider your planned retirement age and most require the debt to be cleared before you stop working, which limits how far the duration can be extended.

Shortening the Mortgage Term

Reducing the loan duration is an efficient way to minimise interest costs. If your financial situation improves through salary increases or other capital, a shorter repayment period means that you will become debt-free sooner. Shortening the agreement typically increases monthly outgoings but reduces the interest payments you will need to make over time.

This strategy is effective for those wishing to eliminate debt before retirement. While it requires a commitment to higher monthly payments, the reduction in total interest can save tens of thousands of pounds. It also means that you will own more equity in the home for the purposes of remortgaging, which means that you can release more cash in future remortgage efforts.

We recommend consulting with mortgage and protection advisers to ensure your budget supports this increase. Making this option work for you depends on affordability and your current mortgage balance.

Why Change Your Mortgage Term?

Mortgage agreements should reflect your current life stage. Adjusting the timeline of your current remaining mortgage term is an opportunity to secure a deal that better works for your lifestyle and financial situation.

The most common reason to adjust the repayment timeline is to manage monthly outgoings. If a fixed rate ends during a period of high market rates, costs will rise. Extending the agreement can offset this increase, keeping the monthly total at a manageable level.

Others change the term of a mortgage as part of retirement planning. As you age, you may want to try to settle the debt before your income changes. If you intend to downsize in the future, a shorter duration might be more beneficial to maximise equity for your next purchase.

Do I Need to Remortgage?

It is not always necessary to remortgage to secure a better financial position. For example, you can often reduce the repayment period without a formal contract change. Most lenders permit annual overpayments of up to 10 per cent of the balance without fees.

Consistent overpayments effectively shorten the timeline without a permanent commitment to higher costs. For example, paying an extra few hundred pounds monthly could take years off your mortgage, but with the flexibility that if your circumstances change, you can stop the overpayments and return to standard monthly outgoings.

If you are remortgaging to save money, bear in mind that you may face early repayment charges if you are still within the fixed term of a mortgage product. These penalties for an early remortgage can amount to more than the interest paid and thereby cancel out the savings you could make by extending your mortgage term.
