Interest only mortgages

Information for new and existing customers.

What do I need to remember?

With an interest-only mortgage, your monthly payment pays only the interest charges on your loan – you don’t pay off any of the loan amount and won’t be reducing the loan.

Ilustration of the effect of monthly payments on a £100,000 interest-only loan over the mortgage term

This means that although your monthly payments will be less than if you had a repayment mortgage at the end of the mortgage you’ll still owe the amount you borrowed. The total cost of an interest-only mortgage will be higher because you will be paying interest on the full loan amount  throughout the mortgage term. 

Interest-only mortgages are only available when the amount of the loan is less than 75% of our latest valuation of the property (or less than 60% if your repayment plan is to sell your home, with a further 15% available on repayment). Please note: these limits change from time to time but were correct at November 2023.

With an interest-only mortgage, you will need to know from the start how you are going to find a lump sum to repay the loan at the end of the mortgage term. When you apply, we’ll ask you to show us the repayment plan(s) that should provide enough money to repay everything you owe by the end of the mortgage term.

From time to time, we may ask you to show us that your repayment plan(s) remains on track to repay the mortgage.

What type of repayment plans can I use?

This table sets out the repayment plans we currently accept which may change in the future.

All evidence must be given on letter headed paper, from your repayment plan provider.

Sale of Second Home/Buy to Let (UK)

We’ll check the ownership of the property and assess its value. We’ll deduct any amount you owe that’s secured against the property and allow you to use up to 80% of the amount left over (provided that this is over £50,000)

Sale of Second Home/Buy to Let not yet purchased (UK)

Property details. Acting solicitor to confirm intended ownership and details of any loans to be secured against this property.

We’ll confirm the intended ownership and assess its value. We’ll deduct any amount you’ll owe that’ll be secured against the property and allow you to use up to 80% of the amount left over (provided that this is over £50,000)

Sale of the security property (UK)

A signed declaration. This form will be provided by TSB for you to sign.

We’ll assess the property value. We’ll deduct the amount you owe that’s secured against the property and allow you to use the sale of your home as a repayment plan where the equity within the property is over £300,000.

As with any investment, there is a risk that it may not cover your outstanding mortgage balance at the end of its term. This means you may need to sell your property to repay your mortgage.

We cannot provide advice on your investment plan. If you need or want advice, please speak to an Independent Financial Adviser.

If your repayment plan is the sale of your home, remember that the value of your home can go down as well as up. This could affect your plans – for example the type, location, and cost of a home you might want to downsize to.

How long it takes

Once your completed forms and evidence have been received and reviewed, we will let you know if your evidence has been accepted or if we need more information. We normally respond within 30 working days if possible, however there may be occasions we don't meet these timescales.

Keeping on track with your repayment plan

Staying on top of your finances throughout the life of your mortgage will help you keep on track or even reach your goal sooner. While it’s your responsibility to keep an eye on your repayment plan, we will check with you that your plan remains on track and support you as far as possible. From time to time, we may ask you to show us that your repayment plan(s) remains on track to repay the mortgage. If we think your plan may not be enough to repay everything you owe by the end of the term, we’ll try to contact you to discuss other arrangements. These may include transferring part, or all, of your loan to a repayment mortgage. 

What if I don't have a plan in place?

If you don’t have a plan in place it’s important that you act now. Please contact us on 0345 835 3389 as soon as possible so we can discuss the options and help you put a plan in place. Lines are open 8:30am - 7pm Monday to Friday and 8:30am - 1pm on Saturdays.

These are some of the repayment plan options available:

  • Switching all of your mortgage to repayment basis - this will mean that your monthly payment will increase but your full mortgage will be repaid at the end of the term
  • Switching part of your mortgage to a repayment basis
  • Pay into an investment plan which can be used to pay off the capital at the end of the term
  • Make lump sum overpayments or set up regular overpayments but first check your mortgage offer to see if an Early Repayment Charge would apply. 

Worried your repayment plan isn't sufficient?

Even if you’re a few years away from the mortgage end date – the longer you leave it the fewer options you’ll have to get back on track so it’s important you contact us as soon as possible. If you have a plan in a place but you don't feel it'll cover the amount owed at the end of your mortgage, please call 0345 835 3389 and we'll be able to go through the options available to you.
