Business rates will not be payable in the first three months that a property is empty. This is extended to six months in the case of certain industrial properties.
A building is classed as empty (unoccupied) if it isn't being used and all stock and effects have been removed (apart from fixtures and fittings).
A change in ownership, lease or tenancy termination does not start a further rate free period.
The liability for empty property rate rests with the "person (or company) entitled to possession". This could be the tenant or leaseholder (if there continues to be a valid tenancy or lease) or the owner of the property.
