Local knowledge
What we see on Dartford roofs.
Roofs & housing in Dartford
The Fleet estate and Temple Hill's post-war semis take standard 10–12 panel arrays; newer riverside developments often have shallow-pitch roofs where we spec higher-output panels to maximise yield.
Planning & permissions
Almost all Dartford installs proceed under permitted development; the town-centre conservation area around Holy Trinity is the main check, done free at design stage.
Real pricing, custom design
Recent ECONEXIS installs start from £4,990 for solar only, or £6,690 with battery storage — up to around £14,000 for our largest systems. Every Dartford design is built around your actual roof and usage, and your free custom design is usually back within 24 hours.

Solar in Dartford — your questions
Who installs solar panels in Dartford?
ECONEXIS is an MCS-accredited solar panel, battery storage and heat pump installer covering Dartford and the DA1–DA2 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 Dartford?
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: The Fleet estate and Temple Hill's post-war semis take standard 10–12 panel arrays; newer riverside developments often have shallow-pitch roofs where we spec higher-output panels to maximise yield, which shapes how many panels fit. Your fixed Dartford quote is confirmed after a free custom design — usually within 24 hours.
Do you actually cover Dartford and the DA1–DA2 postcodes?
Yes — Dartford is part of our core install area. We cover DA1–DA2 and the surrounding Kent neighbourhoods, with a company owner on every install. We're also regularly in Crayford and Stone, so you'll rarely wait long for a survey slot.
How quickly can you install in Dartford?
Your free custom design usually comes back within 24 hours. After your survey and go-ahead, most Dartford 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 Dartford?
In short: Almost all Dartford installs proceed under permitted development; the town-centre conservation area around Holy Trinity is the main check, done free at design stage. 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 Dartford install?
We do, completely. We prepare and submit the DNO application for your Dartford property, manage any conditions, and register the system for MCS certification — you don't fill in a single form.
What savings can a Dartford 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 Dartford — never a generic promise.
