How do solar panels and a battery work together?
Panels make power by day. The battery keeps what you don't use, and your home runs on it in the evening.
Daytime. Your panels power the house first. Spare power fills the battery, and anything left over goes to the grid — you can be paid for it under the Smart Export Guarantee. Evening. The battery runs your home on the power your panels made today. The grid only tops up when the battery runs low.
What we fit: all-black panels by AIKO, LONGi and DMEGC · batteries and inverters by Fox ESS, Sigenergy and Tesla Powerwall 3 · power-cut backup with a backup gateway, quoted at survey.

What we see on Chelmsford roofs.
The roofs, the planning rules and how we price your home.
Roofs & housing in Chelmsford
Near the centre you'll find Victorian and Edwardian terraces. Springfield, Moulsham and Great Baddow are mostly large inter-war and post-war semi estates. Beaulieu and Channels are substantial modern developments.
The suburban semis have concrete interlocking tiles at a friendly working pitch, so they design quickly. The new-build estates use trussed roofs (factory-made timber frames) that take mounting rails cleanly. Extensions are common, and often add a second roof slope you can use.
Planning & permissions
Almost all Chelmsford installs go ahead under permitted development. The exceptions are the city council's conservation areas around the cathedral quarter, Moulsham Street and New London Road. There, a street-facing array needs confirming before it is ordered.
We check your exact address during your free roof design.

Real pricing, custom design
Every Chelmsford design is built around your actual roof and how much power you use. We design from aerial imagery before anyone visits, then confirm it on site.
That's how we work across CM1–CM3 and neighbouring Springfield, Great Baddow, Writtle. Your free roof design and fixed price are usually back within 24 hours, 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.

Solar in Chelmsford — your questions
Do you actually cover Chelmsford and the CM1–CM3 postcodes?
Yes — Chelmsford is part of our core install area. We cover CM1–CM3 and the surrounding Essex neighbourhoods, with a company owner on every install. We're also regularly in Springfield and Great Baddow, so you'll rarely wait long for a survey slot.
How quickly can you install in Chelmsford?
Your free roof design and fixed price usually come back within 24 hours. After your survey and go-ahead, most Chelmsford installations are booked within a few weeks and completed in one to two days on site.
Do I need planning permission for solar panels in Chelmsford?
Usually not. Almost all Chelmsford installs go ahead under permitted development. The city council keeps conservation areas around the cathedral quarter, Moulsham Street and New London Road. There, a street-facing array needs confirming before it is ordered. We check the rules for your exact address during your free roof design and handle any paperwork needed — you won't have to deal with the council yourself.
Who handles the DNO application for my Chelmsford install?
We do, completely. We prepare and submit the DNO application for your Chelmsford property, manage any conditions, and register the system for MCS certification — you don't fill in a single form.
