Building Regulations

Town and Country Planning

Your PERFECTHEAT Solar Thermal System does not normally require planning permission
if it is to be installed in a residential (non-commercial) dwelling house.

Statutory Instrument 2008 No. 675 : The Town and Country Planning (General Permitted Development) Order came into force on 6th April 2008 allowing installation of domestic microgeneration equipment as - permitted development in England.

Please note that it is the property owner who is responsible for obtaining the necessary permissions - not PERFECTHEAT nor the installer.

For your information, the Act says:

(c) the surface area of the solar panels forming part of the stand alone solar would exceed nine square metres or any dimension of its array (including any housing) would exceed three metres.

Conditions
B.2. Development is permitted by Class B subject to the following conditions;
