Solar panel installation in Dartford
Dartford sits right on our doorstep across the river — inter-war semis, post-war estates and the big modern developments around Stone and The Bridge all suit solar well. Across DA1–DA2 we handle custom design, MCS installation, the DNO application and every certificate.
We work right across Dartford — from Central Park, the Orchard Theatre and the Darent Valley path to the surrounding Kent neighbourhoods.
Postcodes covered: DA1–DA2 · Kent
Local knowledge
What we see on Dartford roofs.
Roofs & housing in Dartford
Dartford spans three quite different stocks: Victorian terraces near the town centre, post-war estates through Temple Hill and Stone, and recent development on former industrial land towards the river. The terraces tend to be slate, the post-war housing concrete tile, and the new-build modern trussed construction - each takes a different fixing, which is why we survey before finalising a design rather than quoting from a postcode.
Planning & permissions
Permitted development covers the large majority of Dartford installs. Dartford Borough Council maintains conservation areas around the older town centre, and the flat riverside ground means neighbouring rooflines are the usual shading consideration rather than terrain.

Real pricing, custom design
Every Dartford 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 DA1–DA2 and neighbouring Crayford, Stone, Wilmington. 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.
