Solar panel 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
Local knowledge
What we see on Grays roofs.
Roofs & housing in Grays
Grays mixes Victorian terraces near the town centre and the river with inter-war and post-war semis further out, plus newer riverside development on former industrial land. The terraces are more often slate, which needs the right fixings rather than a different approach; the semis carry concrete interlocking tile at friendly working pitches. Thurrock's flat ground means neighbouring rooflines, not terrain, are the usual shading factor.
Planning & permissions
Permitted development covers the large majority of Grays installs. Thurrock Council maintains conservation areas around the older parts of town and the riverside, so a front-facing array in those streets is worth checking first - we confirm the status of your exact address during your free roof design.

Real pricing, custom design
Every Grays design is built around your actual roof and usage. We design from aerial imagery before anyone visits, then confirm on site, across RM16–RM20 and neighbouring Chafford Hundred, South Ockendon, Stanford-le-Hope. 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.
