What is an interest only mortgage?
- An interest only mortgage allows you to make monthly payments that just cover the interest on the money you have borrowed. These payments do not pay off any capital of the sum originally borrowed.
- This means that you’ll need to repay the full mortgage amount in one lump sum at the end of the mortgage or when you sell the property.
What's the difference between interest only and capital repayment mortgages?
An interest only mortgage allows you to pay just the interest charges on your mortgage loan. A capital repayment mortgage allows you to pay both the capital and interest off on your loan. Most mortgages are capital repayment mortgages.
Interest only mortgages
- Aninterest only mortgage, a type ofmortgage where you pay just the loan's interest. Once you reach the end of the mortgage term, you're required to repay the original mortgage amount (capital) in full.
- There's a higher risk of negative equity than a repayment mortgage. The mortgage balance remains the same over the mortgage term, leaving you more exposed to changes in house prices.
- The total amount paid in interest over the life of an interest only mortgage will also exceed the interest paid on a repayment mortgage.

Capital repayment mortgages
- Acapital repayment mortgage, also known as arepayment mortgage, means you'd be paying back part of the mortgage and interest each month, the monthly payments are calculated so that the loan is paid off at the end of the mortgage term.
- By paying off bothcapital and interest, your total debt will reduce over time, meaning the amount you owe in interest will begin to reduce.

- You can pay off your interest only mortgage early, but there may be limitations to the amount you can repay without incurring anEarly Repayment Charge (ERC), depending on your mortgage.
- Check your mortgage terms for more information on repayments limits or charges.
What happens at the end of an interest only mortgage?
- The remaining balance of your interest only mortgage will need to be repaid in full at the end of your term. This is the capital you borrowed to buy your home at the beginning of the contract. The repayment is usually made as a lump sum, as agreed when you took out the mortgage.
- If you are in the position where you can't repay the loan in full you may be able to get an extension on the mortgage term or remortgage. Another option to look at is whether you have equity in the property, this could also be used to pay off the mortgage.
Setting an interest only mortgage repayment plan
If you apply for an interest only mortgage, we will work with you to agree a repayment plan to pay off the borrowed capital - your plan can also include an endowment, a pension plan, or a stocks and shares ISA. You are liable to repay all the capital borrowed, even if you fall short at the end of the term.
Repayment plan information
Reviewing your repayment plan
It’s important that you stick to your repayment plan and this means reviewing it often to ensure it remains on target.
Occasional check ins
We may check in with you occasionally and ask you to show us that you’re on track and in a healthy position to pay off your mortgage at the end of the agreement.
Keep an eye on the housing market
You could struggle to pay off the full amount if you’re only able to sell the property for a lower value than expected. This may leave you short on equity and unable to purchase another property.
At the end of the mortgage term
If, at the end of your mortgage term, you choose to repay your capital by selling the property, it’s important to remember that the value of your house may vary in line with future average house prices.
Information for interest only mortgage customers
The Financial Conduct Authority (FCA) has published research into consumers’ ability to repay interest only mortgages when they mature. The findings show that many should be in a good position to repay their mortgage when it is due for repayment.
However, some borrowers will need to take control of their mortgage repayment planning now. To that end the FCA, the Council of Mortgage Lenders and the Building Societies Association are working together to ensure lenders contact their borrowers to prompt them to check their repayment plan is on track and to consider the options available to them.
The FCA believes that with careful planning, consideration and engagement with their lender, many interest only borrowers should be able to find a viable way to pay off their mortgage if they take control now.
