An annex is living accommodation attached to the main property which has been built or adapted to be used as self-contained accommodation.
Council Tax is normally paid in full for an annex. In certain circumstances you may be able to apply for a reduction.
You can apply for a 100% reduction where the annex is occupied by a dependent relative aged 65 or more, or is severely mentally impaired or disabled, or where the annex is empty and is not able to be let due to planning restrictions.
You can apply for a 50% reduction where the annex is occupied by a family member or where it is not occupied and used as part of the main residence.
