The law currently only allows compensation for planning blight to be sought from the authority proposing a scheme under the Land Compensation rules, which is nothing to do with Council Tax legislation. You may wish to contact the Department of Transport direct for further information about the HS2 rail link, for example, or the local authority responsible for the scheme.
For Council Tax queries, the Valuation Office Agency can deal with your enquiry. There is no charge for this service. Find the contact details of your regional VOA office here.
