Four ways you can pay your mortgage off sooner (and one reason you might not want to)

Paying off your mortgage sooner: what actually helps

For many people, a mortgage is the largest financial commitment they’ll ever make. It’s understandable to want to clear it as quickly as possible—both to own your home outright and to reduce the interest paid over the life of the loan.

There are several ways to move closer to mortgage-free status. Some reduce the interest you pay, others reduce the time you’re paying it, and a few can do both.

Below are four common approaches, followed by one important reason you might decide not to overpay in certain situations.

1) Switch to a cheaper deal (remortgage)

If your current mortgage rate is higher than what you could get elsewhere, remortgaging can be one of the most effective ways to reduce the cost of borrowing.

When you remortgage, you may be able to:

• Lower your interest rate (which can reduce monthly payments and/or total interest)
• Change the structure of the mortgage (for example, moving from a higher-cost period to a new fixed rate)
• Reconsider the term (for example, keeping the same term or shortening it)

Even if you remortgage mainly to reduce monthly payments, the extra cash flow can sometimes be redirected into overpayments—creating a second lever to pay the mortgage off sooner.

2) Make overpayments (and understand the limits)

Overpayments are payments made in addition to your normal monthly amount. They can reduce the outstanding balance, which typically reduces the interest charged going forward.

How overpayments can affect your mortgage

• Smaller, regular overpayments can add up over time
• Lump-sum overpayments may be useful if you receive savings, bonuses, or other one-off funds
• Shortening the term is sometimes possible if your lender allows you to apply overpayments in a way that reduces the length of the mortgage

Early repayment charges and overpayment rules

Many mortgages have conditions around overpayments—particularly during fixed-rate or discounted periods. Common considerations include:

• Early Repayment Charges (ERCs) may apply if you make certain additional payments during a fixed or discounted term
• Annual overpayment allowances: some mortgages allow you to overpay up to a set percentage of the balance each year without triggering ERCs

If you’re planning to overpay beyond any allowance, it’s important to check how your mortgage contract treats additional payments during the current rate period.

3) Shorten the mortgage term

Another way to reduce the total interest paid is to reduce the number of years you repay the mortgage.

If you shorten the term, your monthly payments usually rise, but you’re typically paying interest for fewer years.

What to consider when shortening the term

• Affordability: can you comfortably meet the higher repayments?
• Flexibility: if your income changes, would you still be able to keep up?
• Timing: remortgaging can be a practical moment to review the term, because you’re already changing the mortgage deal

Even making a modest reduction in term length can change the overall interest cost, because interest is charged over a shorter period.

4) Consider an offset mortgage (if you have savings)

An offset mortgage links your savings to your mortgage balance. In many offset structures, the savings reduce the amount of mortgage balance that interest is calculated on.

Why this can help

• You may reduce interest without necessarily reducing your savings balance
• You may keep access to your savings (depending on the product design)
• If you continue making your normal mortgage payments, the effect of offsetting can help you repay sooner

A trade-off to be aware of

Offset mortgages are not always the cheapest option. They may come with a higher interest rate than a traditional mortgage. Whether they make sense often depends on:

• How much savings you have
• The interest you earn on those savings
• The mortgage rate difference between an offset deal and a standard repayment mortgage

…and one reason you might not want to overpay on your mortgage

Overpaying your mortgage can be a sensible goal—especially if you’re trying to reduce interest and become mortgage-free sooner.

However, there’s a key situation where overpaying may not be the best first move.

If you have other higher-interest debt

If you also have borrowing elsewhere—such as credit cards or certain personal loans—you may be paying a higher interest rate on those balances than you pay on your mortgage.

In that case, it can be worth considering whether it’s more cost-effective to prioritise clearing the more expensive debt first. Paying off higher-interest borrowing can reduce your overall interest costs faster.

Choosing the right approach

The best strategy depends on your circumstances, including your current mortgage rate type, whether you’re in a fixed period, your savings, and your wider debts.

For many borrowers, a combination works well—for example, remortgaging to improve the rate, then using any extra affordability to make overpayments (within the rules of the mortgage).
