Annexe discount

A 50% reduction in the payable council tax is available for annexes. The annexe has to form part of a single property (within the grounds of the main house but not necessarily attached) and:

  • be used by the occupier of the main house as part of the main home, or
  • be occupied by a relative of the person living in the main house

The 50% reduction is on top of any other discount you or your relative may be entitled to but will be applied against the balance payable.

If you think you qualify for this discount please email

There are some circumstances where no council tax is payable in respect of an annexe. These can be found on our exemptions page.
