Solar & battery installation in Sevenoaks
Sevenoaks combines some of Kent's largest family homes with some of its highest energy bills — and roofs with the space to do something serious about them. We install across TN13–TN15 from Riverhead to Kemsing, with a company owner on every job.
We work right across Sevenoaks — from Knole Park, The Vine cricket ground and the High Street to the surrounding Kent neighbourhoods.
Postcodes covered: TN13–TN15 · Kent
Local knowledge
What we see on Sevenoaks roofs.
Roofs & housing in Sevenoaks
Substantial Edwardian and interwar homes around the town and towards Kippington offer big, well-pitched roofs where 14–20 panel arrays fit comfortably, while the post-war streets towards Otford and Seal carry simpler roofs that still take a full family-sized system. All-black panels are the usual spec on these streets.
Planning & permissions
Much of the area proceeds under permitted development, but Sevenoaks has real sensitivities: conservation areas around the historic core and The Vine, listed properties, and the Kent Downs National Landscape on the fringes. We establish exactly what applies to your address before anything is ordered.
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 Sevenoaks design is built around your actual roof and usage, and your free custom design is usually back within 24 hours.

Solar in Sevenoaks — your questions
Who installs solar panels in Sevenoaks?
ECONEXIS is an MCS-accredited solar panel, battery storage and heat pump installer covering Sevenoaks and the TN13–TN15 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 Sevenoaks?
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: Substantial Edwardian and interwar homes around the town and towards Kippington offer big, well-pitched roofs where 14–20 panel arrays fit comfortably, while the post-war streets towards Otford and Seal carry simpler roofs that still take a full family-sized system, which shapes how many panels fit. Your fixed Sevenoaks quote is confirmed after a free custom design — usually within 24 hours.
Do you actually cover Sevenoaks and the TN13–TN15 postcodes?
Yes — Sevenoaks is part of our core install area. We cover TN13–TN15 and the surrounding Kent neighbourhoods, with a company owner on every install. We're also regularly in Riverhead and Otford, so you'll rarely wait long for a survey slot.
How quickly can you install in Sevenoaks?
Your free custom design usually comes back within 24 hours. After your survey and go-ahead, most Sevenoaks 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 Sevenoaks?
In short: Much of the area proceeds under permitted development, but Sevenoaks has real sensitivities: conservation areas around the historic core and The Vine, listed properties, and the Kent Downs National Landscape on the fringes. We establish exactly what applies to your address before anything is ordered. 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 Sevenoaks install?
We do, completely. We prepare and submit the DNO application for your Sevenoaks property, manage any conditions, and register the system for MCS certification — you don't fill in a single form.
What savings can a Sevenoaks 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 Sevenoaks — never a generic promise.
