When you’re taking out a new mortgage deal, one of the key questions to answer is: do I want a fixed- or variable-rate mortgage? There isn’t a straightforward answer to the question. It’ll depend on your circumstances and your plans.
If you choose a fixed-rate mortgage, the rate of interest and your repayments will remain the same until the deal runs out. The key benefit of this option is that you know how much your outgoings will be each month. So, if you’re unsure if you could incorporate higher outgoings into your budget, a fixed-rate mortgage may make sense.
In contrast, the interest rate you pay on a variable-rate mortgage may rise and fall during the deal. This would have a direct effect on your mortgage repayments.
Imagine you have a £200,000 repayment mortgage with a 20-year term. With an interest rate of:
- 4.5% your repayment would be £1,265
- 4% your repayment would be £1,212.
As you can see, even a small difference in the interest rate could change your repayment by hundreds of pounds a year.
So, in what scenarios might a variable-rate mortgage be the right option for you? Here are three.
1. You think interest rates will fall
If you take out a variable-rate mortgage and the interest rate falls, you’d benefit from lower repayments. As a result, if you believe the Bank of England (BoE) or your lender will cut interest rates during your mortgage term, it could make financial sense to choose a variable option.
The BoE last cut the base interest rate in February 2025 to 4.5% when figures suggested inflation was stabilising. Experts predict there will be several more cuts throughout 2025, taking the base rate to around 4%, as inflation nears the 2% target.
As a result, if you’re weighing up your mortgage options, a variable-rate mortgage may look like an attractive one.
Remember, while economists are predicting that the BoE will cut the base interest rate, this is not guaranteed. A range of factors affect the BoE’s decision, some of which cannot be predicted. In the last few years, the Covid-19 pandemic and war in Ukraine have influenced the base interest rate.
So, it’s important you consider how an interest rate rise might affect your finances and your ability to meet the repayments.
2. You plan to move home soon
Usually, when your current mortgage deal ends, it’s advised that you search for a new deal.
This is because you’ll normally be moved on to your lender’s standard variable rate (SVR), which often isn’t competitive, but if you plan to move home soon, it could be a useful option.
The key benefit of an SVR is that you’re not locked into a deal for a defined period. So, when you find your next home, you could avoid paying an early repayment charge (ERC), which is normally a percentage of the outstanding mortgage balance.
It’s worth doing some calculations to understand which would be the best option for you financially. If you’re paying a higher interest rate by remaining on the SVR, the extra you’re paying each month could be higher than the ERC.
3. You want to overpay your mortgage
Overpaying could mean your mortgage-free sooner and save you thousands of pounds over the full mortgage term.
If you have a £200,000 20-year repayment mortgage with an interest rate of 4.5%, your regular repayments would be £1,260 a month. However, if you boosted that by £150 each month, you’d save more than £18,000 in interest alone and pay off your mortgage three years and two months earlier than planned.
You might also choose to make a one-off overpayment.
However, if you’ve locked in a mortgage deal, you can usually only overpay by 10% of the outstanding balance each year before you might pay an ERC.
Again, by moving on to your lender’s SVR, you could have the flexibility to overpay more without a fee. Keep in mind, that the higher interest rate you may pay on an SVR could offset some of the savings you’ve made by overpaying.

A variable-rate mortgage deal could save you money if interest rates fall, while paying the SVR might suit you if your plans could lead to an ERC.
