Discounts and exemptions for annexes

Council tax exemptions and discounts for annexes

About Annexes

An annexe is a self-contained unit which: 

  • Is generally a building or part of a building which has been constructed or adapted for use as separate living accommodation
  • Will include a kitchen area, a bath or shower room, toilet, living space and sleeping space
  • May share an entrance with the main house and common services 

If a residential property contains more than 1 unit of self-contained accommodation, the main house and each self-contained unit (or annexe) will have its own Council Tax band determined by the Valuation Office Agency.

Discount amount

You may be able to get a 50 percent discount if either of the below apply to you:

  • The annexe is lived in by immediate family members, including parents and teenagers, where other family members live in the main building
  • The annexe is used as part of the main residence but otherwise unoccupied

Apply for Annexe discounts

If someone who's not a family member lives in the annexe then you won't be able to get the discount.
