St Albans has Victorian and Edwardian terraces around the centre and in Fleetville, with a large conservation area around the cathedral. Stevenage, the first post-war new town, and Hemel Hempstead have estates of plain 1950s and 1960s roofs that suit a standard layout. Welwyn Garden City and Letchworth Garden City are a special case: both have estate management schemes, so solar needs the scheme’s consent as well as the usual checks. Watford, Bushey and Rickmansworth are largely 1930s semis and post-war houses with drives.
Planning goes through the borough or district council, such as St Albans, Dacorum, Watford, Welwyn Hatfield, North Herts or East Herts. The Chilterns National Landscape covers the west of the county around Tring and Berkhamsted. The network operator is UK Power Networks. Royston and the villages along the northern border are at the edge of the area we cover, so call first. Hertfordshire is more than 90 minutes from Ferndown, so the first survey is usually a video call, then a site visit. Installs are scheduled in groups.
