Solar Panels Cobham
Solar panels, battery storage and EV chargers for homes in and around Cobham — designed from your actual usage, installed by an MCS-certified team, and explained in plain English before you commit to anything.
Cobham is really two settlements that grew into one: Church Cobham, gathered around the Grade I listed Church of St Andrew by a crossing of the River Mole, and Street Cobham, strung along the old Portsmouth-to-London coaching road. Add the leafy Fairmile to the north-east, semi-rural Downside beside Cobham Park, and Stoke D'Abernon and Hatchford filling out the edges, and you get a town of period cottages and generously plotted detached homes about nine and a half miles north-east of Guildford, centred on the KT11 postcode district.
If you want local proof that solar is being taken seriously here, look to the edge of town. In October 2025 Extra MSA completed one of the largest single-site solar projects in UK motorway service history at Cobham services on the M25 — 810 panels expected to generate up to 305,159 kWh of clean energy a year and cut the amenity building's grid-supplied energy by 24%. Domestic roofs run on the same physics at a smaller scale, and the light is there: the Met Office climate station at Wisley, about three miles away, averaged 1,584 hours of sunshine a year over 1991–2020, roughly 13% above the UK-wide figure of about 1,400 hours. That makes Cobham slightly better-lit than the national average — not a sun trap, and we won't pretend otherwise.
We quote for homes in and around Cobham, and the pattern rarely changes: your roof's orientation, pitch and shading decide most of the outcome, how you use electricity decides the rest, and battery storage deserves pricing alongside the panels rather than as an afterthought. You can test your own figures with our savings calculator, or read on for what is genuinely local — the conservation areas, the council's record and the housing stock itself.
Solar on Cobham's housing
The 2021 Census counted 3,721 households in Cobham and Downside ward, and the split favours rooftop solar: 30.9% live in detached houses and 27.6% in semi-detached — nearly 59% of the ward in house types with their own roof and, usually, their own say over what goes on it (ONS TS044). Terraced homes account for a further 18.4%, mostly in the older streets, and purpose-built flats for 19.2%. The wider Cobham built-up area reached 17,506 residents in 2021, up modestly from 16,963 a decade earlier — steady growth rather than a building boom, which is why so much of the stock is established family housing on mature plots across Fairmile, Downside and Stoke D'Abernon.
Tenure tilts the same way. Some 35.0% of ward households own their home outright and another 30.3% own with a mortgage (ONS TS054) — around two in three homes where the decision to install sits with the people living there. Across Elmbridge as a whole, ownership stood at 71.3% at the 2021 Census, well clear of the England figure of 61.3%. The remaining third needs a different conversation: the 19.6% of ward households renting privately will need their landlord's agreement before anything is fixed to the roof, and leaseholders in flats generally need freeholder or management-company consent — worth sorting out early, before anyone books a survey.
Heritage is the local complication worth understanding precisely. Cobham carries three designated conservation areas. The main Cobham Conservation Area, designated on 31 July 1973, covers the historic Church Cobham core and the River Mole around Mill Road, River Hill and Church Street — home to the Grade I listed Church of St Andrew, the Grade II* Ham Manor, Cedar House and Church Stile House, and the Grade II Cobham Mill. The Tilt (designated 1979, extended 2015) and Cobham Plough Corner (1990, around the Downside Road and Plough Lane junction) complete the set. Roof-mounted panels usually remain permitted development even in a conservation area — the specific restriction is on panels fixed to a wall fronting a highway — but siting on these streets calls for conservation-aware design. Elmbridge has also confirmed Article 4 directions on land off Pointers Road (confirmed 2020) and Woodlands Lane (confirmed 2024); they withdraw permitted development rights for means of enclosure and temporary uses of land rather than for solar itself, but they mark parts of town where checking designations first is simply good practice.
What Elmbridge Borough Council is doing
Elmbridge Borough Council declared a climate emergency in July 2019 and set itself two dates: carbon-neutral as an organisation by 2030 and a carbon-neutral borough by 2050, underpinned by a Carbon Management and Reduction Plan 2030 first published in September 2020 and revised annually since. Unusually, the council has matched the paperwork with panels of its own — 973 went live at its Xcel Leisure Complex in December 2022, expected to cut the site's electrical consumption by around 40% and save an estimated 75-plus tonnes of CO2 a year, followed by a 63-panel solar carport in the Civic Centre car park, completed in June 2023.
For households, the practical route is Solar Together Surrey — the group-buying scheme managed by Surrey County Council with independent experts iChoosr, using collective purchasing to bring installation costs down. Elmbridge homes, Cobham included, are eligible; the 2025 round took registrations from 16 June to 29 August 2025, and the scheme runs in rounds, so check what is currently open before building plans around it. Registering costs nothing and commits you to nothing — and comparing the group offer against an independent quote is exactly the kind of decision-making we would encourage.
What solar costs on a Cobham home
The honest national anchor is the Energy Saving Trust's: a typical domestic system is around 4.5 kWp — roughly around 12 panels over 20 to 30m² of roof — and costs around £7,600 installed. On their payback table, with export payments and fuel prices as of July 2026, London homes sit at about 9 years. Elmbridge households, Cobham included, are eligible for Solar Together Surrey's group-buying rounds — worth comparing against a normal installer quote on the same specification rather than assuming one is cheaper.
Two things move that number for everyone. Residential installations carry 0% VAT until 31 March 2027, reverting to 5% from 1 April 2027. And export payments under the Smart Export Guarantee are set by each supplier and must be above zero — they change on short notice, which is why we never print one. A quote should itemise the panels, inverter, mounting, scaffolding, labour, commissioning, warranties and the DNO notification, so you can see what the total is made of — ours does, and it comes from a survey of your actual roof and usage, not from a table.

When we'd tell you not to fit solar in Cobham
A persistently shaded roof, a slope that faces mostly north, a listed building where consent will not carry the fixings, or a home whose daytime usage is so low that almost everything would be exported at a supplier-set rate — in those cases we will say so at the survey rather than sell you a system that under-delivers. Fabric-first improvements sometimes beat panels as the first spend, and we would rather tell you that than not.
Whoever you use, check the registers yourself: HCE is NAPIT member 73495 and an HIES Consumer Code member (HCE/A/1392), with MCS certification for solar PV via NAPIT — the certification an MCS-certified install needs for Smart Export Guarantee payments.
What a Cobham roof actually generates
Rather than quote a generic yield, we ran the European Commission's PVGIS 5.3 (European Commission Joint Research Centre) for Cobham itself. A 4 kWp array at 35° facing due south, with 14% system losses, is estimated at about 3,990 kWh a year — around 997 kWh per kWp — with a year-to-year variation of roughly ±153 kWh (PVGIS-SARAH3, 2005–2023). East- or west-facing slopes generate less, and shading changes the answer more than the town does; that is exactly what the survey measures.

Cobham solar questions
Do I need planning permission for solar panels in Cobham's conservation areas?
In most cases, no. Roof-mounted solar on a house is generally permitted development in England, and that holds inside Cobham's three conservation areas — the main Cobham Conservation Area of 1973 around Church Street, Mill Road and River Hill, The Tilt (1979, extended 2015) and Cobham Plough Corner (1990). The conservation-area restriction that does bite is on panels fixed to a wall fronting a highway, and flat-roof installations have tighter rules. Listed buildings are the firm exception: properties such as the Grade II* Cedar House and Church Stile House would always need listed building consent. Elmbridge's Article 4 directions in Cobham — off Pointers Road and Woodlands Lane — concern means of enclosure and temporary uses of land rather than solar, but they are a reminder that this is a town where the designations are worth checking against your exact address before any quote is finalised.
Who handles grid connections for solar in Cobham?
UK Power Networks. Cobham falls in UKPN's South Eastern Power Networks licence area — the successor to the old SEEBOARD network, distributing across Kent, Sussex and much of Surrey. Practically, that means your installer notifies UKPN under G98 for a standard domestic system, or applies under G99 for larger arrays or bigger battery setups, before or at connection depending on size. None of this is something you need to arrange yourself — it is part of a competent installer's job — but it is worth knowing which network sits behind your export approval, especially if you later add a battery or an EV charger.
Can Cobham households join Solar Together Surrey?
Yes. Elmbridge is a participating borough, so Cobham households are eligible for Solar Together Surrey — the group-buying scheme managed by Surrey County Council with independent experts iChoosr, which uses collective purchasing power to bring installation costs down. The 2025 round took registrations from 16 June to 29 August 2025, and the scheme operates in rounds, so check what is currently open rather than relying on past dates. Registration is free and carries no obligation, and there is no conflict in doing both: register for the group scheme and get an independent quote, then compare the two on price, kit and workmanship. We are happy to be one of the numbers in that comparison.
The solar array at Cobham services is huge — does that mean solar works well here?
It is certainly a strong local signal. Extra MSA's October 2025 installation at Cobham services on the M25 was one of the largest single-site solar projects in UK motorway service history — 810 panels expected to generate up to 305,159 kWh a year and cut the amenity building's grid-supplied energy by 24%. A commercial operator does not commit to that scale without the generation case stacking up locally. Your roof works on the same physics at perhaps one-hundredth the size: the Wisley climate station about three miles away averages 1,584 sunshine hours a year, and panels generate from daylight rather than direct sun alone. What the services array cannot tell you is whether your particular roof suits panels — orientation, pitch and shading do that — which is why a proper survey beats any headline project.
What payback period should I expect on solar in Cobham?
Nobody can honestly give you a single figure without seeing your roof and your usage, so we will not. What we can tell you is what moves the number. Cobham's high share of detached homes — 30.9% of ward households at the 2021 Census — means many roofs can carry a larger array, which usually improves the economics. How much of your generation you use directly rather than export matters as much as array size, and a battery changes the sums again by shifting daytime generation into evening use. The sunshine input is fixed and sufficient — around 1,584 hours a year at nearby Wisley. Ask for a quote built on your actual roof, usage and tariff, and be wary of any installer who quotes a payback period before seeing either.
How much do solar panels cost to install in Cobham?
Nationally, the Energy Saving Trust puts a typical 4.5 kWp domestic system at around £7,600 installed (updated 27 August 2026), with residential installs at 0% VAT until 31 March 2027 and 5% from 1 April 2027. Elmbridge households, Cobham included, are eligible for Solar Together Surrey's group-buying rounds — worth comparing against a normal installer quote on the same specification rather than assuming one is cheaper. A quote should itemise the panels, inverter, mounting, scaffolding, labour, commissioning, warranties and the DNO notification, so you can see what the number is made of.
What would a typical solar array actually generate on a Cobham roof?
Rather than a generic yield, here is the PVGIS 5.3 estimate for Cobham: a 4 kWp system at 35° facing south with 14% losses comes out at roughly 3,990 kWh a year, or about 997 kWh per kWp, give or take ±153 kWh between years (SARAH3 data, 2005–2023). Orientation and shading move that number far more than your postcode does, which is what a survey settles.
