The Valuation Office Agency (VOA) holds limited information about heating in domestic properties. For arriving at a banding for council tax purposes the presence or absence of heating would only be relevant in those comparatively rare cases where this would significantly affect the property's value. The Automated Valuation Model, developed for the (now postponed) 2007 revaluation, does not therefore treat the presence or absence of heating as a significant factor. The VOA's records provide for the recording of this information if it becomes available. At present fewer than 0.1 per cent. of properties are recorded as not having heating.
