Question to the Ministry of Housing, Communities and Local Government:

To ask the Secretary of State for Housing, Communities and Local Government, what assessment her Department has made of the potential impact of properties that undergo significant structural extensions but remain in their original council tax banding due to legislative restrictions on revaluation on local authority revenues.

Improvements to properties, such as extensions, are not generally taken into account for council tax banding purposes until the property is sold. The government believes it is right that people are not deterred from improving their home by the prospect of their council tax increasing. When the property is sold, the council tax band may increase, but only if the alterations have added sufficient value to push the property into a higher band. The government does not have any plans to change this policy.
