Solar panel installation in Chelmsford

Across CM1–CM3 we handle the full job: custom design, MCS install, the DNO application and certification, with a company owner on site for every Chelmsford installation.
We work right across Chelmsford — from Hylands Park, the city centre and the riverside Springfield areas to the surrounding Essex neighbourhoods.

Local knowledge
What we see on Chelmsford roofs.
Roofs & housing in Chelmsford
Chelmsford spans Victorian and Edwardian terraces near the centre, large inter-war and post-war semi estates through Springfield, Moulsham and Great Baddow, and substantial modern development at Beaulieu and Channels. The suburban semis carry concrete interlocking tile at friendly working pitches and design quickly; the new-build estates use trussed roofs that take mounting rails cleanly. Extensions are common and often add a second usable slope.
Planning & permissions
Almost all Chelmsford installs proceed under permitted development. The city council maintains conservation areas around the cathedral quarter, Moulsham Street and New London Road, where a street-facing array needs confirming before it is ordered. We check your exact address during the free design.

Real pricing, custom design
Every Chelmsford 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 CM1–CM3 and neighbouring Springfield, Great Baddow, Writtle. 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.
