Solar panel installation in Slough
Slough is flat, densely built and mostly inter-war and post-war housing — which for solar is a good combination. Consistent pitched roofs, little natural shading from terrain, and estates built to a repeating pattern. We design and install across SL1–SL3 and the surrounding villages.
We work right across Slough — from to the surrounding Berkshire neighbourhoods.

Local knowledge
What we see on Slough roofs.
Roofs & housing in Slough
Slough is flat, densely built and mostly inter-war and post-war housing - which for solar is a good combination. The large Britwell and Cippenham estates are post-war semis and terraces with plain pitched tiled roofs at friendly working pitches, built to repeating patterns that design quickly. Nearer the centre there are Victorian and Edwardian terraces, more often slate. Chimney stacks and neighbouring rooflines are the usual shading factor rather than trees or hills.
Planning & permissions
Slough Borough Council treats domestic solar as permitted development in almost every case. Conservation areas exist around Upton Court and parts of the older centre but cover a small proportion of the housing stock. We check yours before you commit to anything.

Real pricing, custom design
Every Slough design is built around your actual roof and usage — not a package price off a website. We design from aerial imagery before anyone visits, then confirm on site, across SL1–SL3 and neighbouring Langley, Cippenham, Burnham. Your free design is usually back within 24 hours with the full price in writing.
Package prices are based on one roof elevation with a single scaffold lift. Extra roof faces or additional scaffolding are quoted at survey.
