Money off Council Tax for annexes

Find out about discounts for family and dependant relatives living in annexes.

Annexes to homes usually have a separate Council tax bill. The Valuation Office Agency decides if an annexe must have its own Council Tax band.

An annexe usually has:

  • been built or adapted to use as separate living accommodation
  • its own cooking, toilet and washing facilities
  • a separate entrance to the main home, such as an external door, or a door from a landing or hallway within the main home

For Council Tax, it doesn't matter if the annexe is within the main home or if it is separate.

Annexes and family discount

If you live in an annexe as your main home, you may be able to get a 50% discount on your council tax bill if you are a relative of the person who is responsible for paying council tax on the main property.

Annexes occupied by an elderly relative

An annexe will be exempt (which means you don’t have to pay council tax) if it has a dependant relative living in it as their main, or only, home. A relative is dependant if they are:

  • aged 65 or over
  • substantially or permanently disabled
  • severely mentally impaired
