Solar & battery installation in Grays
Grays and Thurrock — including Chafford Hundred's modern estates — combine Victorian terraces with big 1990s–2000s developments whose roofs were practically made for solar. Across RM16–RM20 we run the whole job: design, MCS install, DNO application and certification.
We work right across Grays — from Chafford Hundred, Grays Beach Riverside Park and Lakeside to the surrounding Essex neighbourhoods.
Postcodes covered: RM16–RM20 · Essex

Solar in Grays — your questions
Who installs solar panels in Grays?
ECONEXIS is an MCS-accredited solar panel, battery storage and heat pump installer covering Grays and the RM16–RM20 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 Grays?
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: Chafford Hundred and Ockendon's newer homes have clean, unshaded double slopes that suit east-west splits; the older terraces near the town centre take compact high-output arrays, which shapes how many panels fit. Your fixed Grays quote is confirmed after a free custom design — usually within 24 hours.
Do you actually cover Grays and the RM16–RM20 postcodes?
Yes — Grays is part of our core install area. We cover RM16–RM20 and the surrounding Essex neighbourhoods, with a company owner on every install. We're also regularly in Chafford Hundred and South Ockendon, so you'll rarely wait long for a survey slot.
How quickly can you install in Grays?
Your free custom design usually comes back within 24 hours. After your survey and go-ahead, most Grays 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 Grays?
In short: Nearly all Thurrock installs go ahead under permitted development — we confirm your address during the free design. 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 Grays install?
We do, completely. We prepare and submit the DNO application for your Grays property, manage any conditions, and register the system for MCS certification — you don't fill in a single form.
What savings can a Grays 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 Grays — never a generic promise.
