Reductions for annexes

From 1 April 2014 annexes which are used by the occupier of the main house as part of the main home or which are occupied by a relative of the person living in the main house, are entitled to a 50% reduction in the Council Tax payable on the annexe

The eligibility for the discount is:

The annexe must form part of a single property which includes at least one other property ie the annexe must be within the grounds of the main house (not necessarily attached) and must be included in the title deeds of the main house and not registered separately.

And either:

• The annexe is being used by the resident of the main house as part of their main home,


• The annexe is lived in by a relative of the person who lives in the main house. For this purpose a relative is defined as: a partner, parent, child, step child, grandparent, grandchild, brother, sister, uncle, aunt, nephew and niece (also includes great grandparent, great grandchild etc. and great great grandparent etc).

If you have a close relative who lives in the annexe and they are over 65 years of age or they are either severely mentally impaired or substantially and permanently disabled we may be able to award an exemption from Council Tax for the annexe. Please complete our online application form.

If the annexe is unoccupied and cannot be let separately because of a planning restriction then it could also be exempt.  Please upload documentation detailing the restriction when completing the application form.
