Letting your property

If you want to let your property, instead of living in the property, you can, but you'll need to get permission from us first.

Remember, that once your property is let, you cannot:

  • switch your mortgage deal
  • take additional borrowing
  • complete a term change
  • add or remove a borrower.
  • change your repayment method.

Unless you are a member of the British Armed Forces or have a critical illness.

If you've already started letting your property

You'll need to get consent from us as soon as possible. Your mortgage terms and conditions explain that you need consent from us to let your property before the let starts and any breach on these conditions could lead to further action being taken.

Fees and charges for letting your property

If you are on a fixed or tracker rate

We’ll add 0.5% to your current interest rate while you’re letting your property. We will give you reasonable notice of any change to the additional letting interest rate and let you know about any amends to the rates by changing our tariff of charges page - PDF 73KB (opens in a new window).

The additional 0.5% added to your rate will end once your fixed rate product ends and you revert to our Standard Mortgage Rate or Base Mortgage Rate.

If you are on our Standard Mortgage Rate (SMR) or Base Mortgage Rate (BMR)

You will not be charged an additional 0.5% to your rate when you let your property.

If you're a member of the British Armed Forces

We won’t charge the additional letting interest rate. When you request consent to let, we’ll require proof you’re still a serving member. Remember that you’ll need to let us know if this situation changes.

Paying tax on profit from renting out your property

You must pay tax on any profit you make from renting out property.

This may mean your rent income moves you into a higher tax band, as your taxable income could increase.

To find out more about paying tax on your rented property, and how to work it out, please visit the UK Government website (opens in a new window).

No information on this site should be taken as tax advice. For advice you should consult with an independent tax adviser.

Making Tax Digital for landlords

From April 2026, some landlords will need to report their income and expenses to HMRC in a new way. This is called Making Tax Digital (MTD) for Income Tax.

MTD may affect you if you have a buy-to-let property or a consent to let arrangement.

Visit our Making Tax Digital for landlords page to find out if you'll need to follow the new rules, when the changes start and what you'll need to do.
