Solar & battery installation in Brentwood
Brentwood, Shenfield and Hutton are dominated by generous 1930s and post-war family homes with big, well-pitched roofs — excellent solar stock. Across CM13–CM15 we design each system around the individual roof, handle the DNO application and every certificate, with a company owner on each install.
We work right across Brentwood — from Shenfield station, Thorndon Country Park and Hutton Mount to the surrounding Essex neighbourhoods.
Postcodes covered: CM13–CM15 · Essex

Roofs & housing in Brentwood
Hutton Mount and Shenfield's larger detached homes regularly take 16–20 panels with room for a high-capacity battery, while the town's semis suit tidy 10–12 panel arrays.
Planning & permissions
Permitted development covers most of Brentwood; parts of Ingatestone High Street and Brentwood's town-centre conservation area get a street-facing check first.

Solar in Brentwood — your questions
Who installs solar panels in Brentwood?
ECONEXIS is an MCS-accredited solar panel, battery storage and heat pump installer covering Brentwood and the CM13–CM15 postcodes, based in Chadwell Heath, Essex. The company is TrustMark, NAPIT and RECC registered, a company owner attends every installation, and the full job — design, install, DNO grid application and certification — is handled in-house.
How much does solar panel installation cost in Brentwood?
Recent real ECONEXIS installs start from £4,990 for a solar-only system, or £6,690 for a 10-panel system with a 5 kWh battery — up to around £14,000 for a 20-panel system with a large battery. As a guide to sizing: Hutton Mount and Shenfield's larger detached homes regularly take 16–20 panels with room for a high-capacity battery, while the town's semis suit tidy 10–12 panel arrays, which shapes how many panels fit. Your fixed Brentwood quote is confirmed after a free custom design — usually within 24 hours.
Do you actually cover Brentwood and the CM13–CM15 postcodes?
Yes — Brentwood is part of our core install area. We cover CM13–CM15 and the surrounding Essex neighbourhoods, with a company owner on every install. We're also regularly in Shenfield and Hutton, so you'll rarely wait long for a survey slot.
How quickly can you install in Brentwood?
Your free custom design usually comes back within 24 hours. After your survey and go-ahead, most Brentwood 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 Brentwood?
In short: Permitted development covers most of Brentwood; parts of Ingatestone High Street and Brentwood's town-centre conservation area get a street-facing check first. We check the rules for your exact address during the free design and handle any paperwork needed — you won't have to deal with the council yourself.
Who handles the DNO application for my Brentwood install?
We do, completely. We prepare and submit the DNO application for your Brentwood property, manage any conditions, and register the system for MCS certification — you don't fill in a single form.
What savings can a Brentwood homeowner expect?
Across our recent quotes, estimated first-year savings ranged from £1,100 to £2,100 with typical payback of 5–8 years, depending on system size and how you use your electricity. Your free design includes savings figures specific to your home in Brentwood — never a generic promise.
