A fixed-rate mortgage means the interest rate on your mortgage is fixed for between two to five years. But what happens when your fixed term ends?

Key takeaways

  • When your fixed term ends, your mortgage interest rate will automatically switch to your mortgage provider's standard variable rate (SVR)

  • This is usually a much higher interest rate, meaning your monthly repayments could go up by hundreds of pounds

  • For that reason, most people opt to remortgage, usually for another fixed-rate deal and the certainty that brings. Or opt to take their chances with a tracker or variable rate mortgage

What can I do when my fixed-rate mortgage ends?

When your fixed-rate mortgage ends, you have two options:

1) Do nothing and stay on your mortgage provider's SVR

When your fixed term comes to an end, you'll automatically be switched to your lender's SVR. 

While there's a small chance that the interest rate will be lower, especially if the Bank of England's base rate is low, it's much more likely that the SVR is higher than your fixed rate. 

Additionally, the SVR is liable to change at any time - and the rate is completely up to your lender's discretion.

2) Remortgage to a new deal 

By remortgaging to a new deal, you can avoid the higher interest rates that often come with an SVR - potentially saving you hundreds of pounds in repayments every month.

You can try to get a new deal with your current mortgage lender, or shop around to find a better one.

If you want to remortgage, it's best to plan ahead around four to six months before your fixed term ends - our guide When is the best time to remortgage your home? goes into more detail.

Remortgaging with a new lender does require having to go through the mortgage application process again, including credit checks.

And if your circumstances have changed - for example, if you've become self-employed, accumulated debts, or have a new baby - this may negatively affect your new mortgage application.

It's also worth bearing in mind that remortgaging comes with set-up costs and admin fees.

What is the penalty for leaving a fixed-rate mortgage?

You can leave your fixed-rate mortgage early, but it'll come at a cost. In most cases, you will have to pay an Early Repayment Charge (ERC) to leave before your fixed term comes to an end.

How much an ERC costs depends on the outstanding mortgage amount and how many years you have left in your term.

Usually, ERCs are between 1% to 5% of the remaining loan, with this percentage decreasing for every year you're into the deal.

If you want to switch to a better mortgage deal without having to pay an ERC, you should plan your remortgage to coincide with the end of your mortgage deal. Alternatively, if you need some flexibility, it's worth staying on your lender's SVR for a few months after your fixed term has ended.

Can you extend a fixed-rate mortgage?

Yes, you have the option to extend your mortgage term. This involves adding to the number of years that you were originally intending to pay back your loan.

While extending your mortgage term can lower monthly repayments, it means a higher cost in the long term - as you'll pay more in interest over the total term of your mortgage. 

However, if you're coming to the end of your fixed term and the interest rate is set to rise by a lot, extending your mortgage term can be a way of making your monthly repayments more affordable.

Another solution to lower monthly repayments is to switch to an interest-only mortgage, which involves paying only the interest each month, leaving the capital debt unchanged.

You don't have to remortgage and get a new loan in order to extend your fixed term. You'll just need to speak with your mortgage lender directly.

Can I change my fixed rate to a variable rate?

Yes, you can change your fixed-rate mortgage to a variable-rate one.

While a fixed rate provides more financial stability, certainty and protection from rising interest rates, a variable rate can be ideal if you're looking for a flexible, short-term plan.

You won't have to pay any ERCs if you want to move to a new deal or provider, nor will you have to pay any fees if you want to pay off some or all of your mortgage early.

Is remortgaging right for me?

While remortgaging typically helps to keep your monthly repayments down, as you may be able to lock in a lower-interest, fixed-term deal, it's not suitable for everyone.

For example, it might be more difficult to remortgage if the value of your home has decreased, or if you have very little equity in your home or are close to retirement age.

If your financial situation has changed - such as going freelance or being out of work - you might not be stable enough to remortgage.

In these instances, it may be better to stick with your lender's SVR for a few months until you're in a more financially stable position to get a new mortgage.

Finally, if you have a relatively small balance remaining on your mortgage, it may work out cheaper to be switched to your lender's SVR than paying for the fees that come with remortgaging.

On an SVR, you can also pay off some or all of your mortgage early without penalty.
