Solar Panels Cobham: Installers for KT11
Solar, battery storage and EV charging in Cobham — designed and installed by a local, MCS-certified team based in Portsmouth.
Quick answer
Cobham (KT11) is on UK Power Networks' grid, and we file the G98 or G99 application for you. PVGIS puts a 4kW south-facing, unshaded array here at about 4,117 kWh a year, and homes in Cobham's two conservation areas get a discreet, all-black design.
Cobham sits on the River Mole in the Borough of Elmbridge, about 17 miles south-west of London, and grew from two settlements: Church Cobham around the 12th-century St Andrew's Church and Cobham Mill, and Street Cobham. Downside lies to the south and Fairmile to the east, and the A3 and M25 run close by. Cobham is also home to Painshill Park, an 18th-century landscape garden.
Property values are high: HM Land Registry put Elmbridge's average detached price at £1,593,107 in July 2026. The roof matters more than the price tag, though, so every design starts with a survey of orientation, pitch and shading. Cobham is about 47 miles from our Portsmouth base as the crow flies, so surveys and installs here are planned visits.
Solar in Cobham: the local detail
Grid connection (DNO)
Cobham is in the UK Power Networks (UKPN) area: our postcode checks put KT11 on the South Eastern network, like nearby Woking and Guildford. G98 covers smaller systems; G99 (applied for in advance) covers batteries and larger arrays — SCSS files the application.

Heritage & conservation
Two conservation areas: Cobham Conservation Area (designated 31 July 1973), covering the historic core of Church Cobham and the River Mole around Mill Road, River Hill and Church Street, and Cobham (Plough Corner), designated 28 November 1990 at Downside Road and Plough Lane. Elmbridge's 2024 Article 4 direction at land off Woodlands Lane covers boundary treatments and temporary uses, not rooftop solar.
Local housing stock
High-value detached homes are a big part of the market: HM Land Registry's July 2026 averages for Elmbridge were £1,593,107 for detached houses, £725,898 for semi-detached, £580,978 for terraced and £353,544 for flats. The listed buildings of Church Cobham, including the Grade I St Andrew's Church and Grade II* Ham Manor, Cedar House and Church Stile House, sit within the conservation area.
Typical roofs
PVGIS 5.3 gives a 4kW unshaded array about 4,117 kWh a year facing south, 3,300 facing east and 3,237 facing west, so an east–west split loses about a fifth of the south-facing yield. We check trees and neighbouring buildings for shading at the survey.
Sunlight & generation
PVGIS models about 4,117 kWh a year for a 4kW unshaded, south-facing array at a 35° pitch

Solar Panels Cobham: Conservation Areas, Yields and the UK Power Networks Connection
Cobham's historic core is protected, but that rarely rules solar out. Elmbridge Borough Council has two conservation areas here: Cobham Conservation Area, designated in 1973 around Church Cobham and the River Mole, and Cobham (Plough Corner), designated in 1990. Under the national rules, panels on the roof slope of a house in a conservation area keep permitted development; panels on a wall, balcony or roof enclosure fronting a highway do not, and a flat-roof array needs prior approval. Listed buildings are different: Class A rights don't apply, so listed building consent comes first. The borough's 2024 Article 4 direction off Woodlands Lane covers boundary treatments and temporary uses, not rooftop solar.
On yield, PVGIS 5.3 gives a 4kW unshaded, south-facing array in Cobham about 4,117 kWh a year, with about 504 kWh in June and 138 kWh in December. That is lower than the Sussex coast, where the same array in Hailsham models at about 4,680 kWh, so orientation and shading make a real difference here and we model both at the survey.
Cobham is on UK Power Networks' South Eastern network, the same as Woking and Guildford. That places it in Octopus's South Eastern tariff region, where Flux paid 29.79p per kWh for 4pm to 7pm exports on 17 September 2026, with Outgoing Octopus at 12p flat. We submit the G99 application to UKPN for any battery before installation.
Our advertised prices apply here too, all "from" and subject to survey: solar from £4,995, solar with a battery from £6,995, and solar with a Tesla Powerwall 3 from £12,920. For larger homes, the Powerwall 3 can be expanded to 27kWh, from £13,950 as a battery-only install.

Do I need planning permission for solar panels in Cobham's conservation area?+
Usually not for panels on the roof slope of a house. In a conservation area the permitted development limit applies to walls, balconies and roof enclosures fronting a highway, and flat-roof arrays need prior approval. Listed buildings, such as those around St Andrew's Church, need consent checked first, and we confirm the position for your address.
Why does a solar array in Cobham generate less than one on the Sussex coast?+
Cobham is further north and inland. PVGIS models a 4kW south-facing, unshaded array at about 4,117 kWh a year in Cobham against about 4,680 kWh in Hailsham, near the East Sussex coast. The difference is worth knowing when you compare savings estimates from different areas.
