Solar panels Surrey cost: 2026 prices

Solar panel installation cost in Surrey sits a little above the national average, as you’d expect this close to London, where labour, scaffolding and parking all cost more. There’s a lot of competition, though. One directory lists about 400 MCS-certified installers who work in the county, around 85 of them based here. Typical 2026 installed prices, all with 0% VAT:

Several things move a Surrey quote. Plain clay tiles, the small handmade tiles on so many older Surrey houses, take longer to fit around than modern concrete tiles and add £300–£800. Tall, complex roofs on large detached houses, with hips, gables and dormers, split the array across several faces and often need optimisers (optimisers). Three-storey houses and homes on sloping plots need more scaffolding. Private estates and gated roads can restrict working hours and vehicle access. A plain two-storey 1930s semi with side access in Ewell, Ashford or Horley is the cheapest install in the county. Larger systems are covered in our 6kW, 8kW and 10kW guides, and the national picture is in solar panel cost UK.

How much you’ll generate and save

Surrey is in the sunnier south-east corner of England, with around 1,600 hours of sunshine a year. A well-oriented, unshaded roof here yields roughly 960–1,050kWh per kW of panels a year, a little above the UK average. One modern 440W panel on a south-facing Surrey roof produces about 420–460kWh a year. For a 4kW system:

*At the October–December 2026 price cap of 26.32p/kWh and 12p export, with about half the output used at home (about 80% with a battery, plus some off-peak winter charging). Homes where someone is in during the day, or with an EV or heat pump, do better. The Surrey catch is trees. With woodland covering more than a fifth of the county, a mature oak or a row of pines to the south can cut these figures by a fifth or more. A proper shade analysis at survey is worth more here than a few extra watts per panel (solar panels and shading). The ideal fixed tilt in Surrey is about 35–38°, but anything from 25° to 45° loses only a few per cent (best angle and direction, roof pitch). Solar panel output has the month-by-month curve, solar panel payback shows the sums, and the calculator will run your own usage.

Home solar panels in Surrey: houses and roofs

Surrey grew up along its railway lines to London, so most of its housing is suburban and dates from the 1900s onwards. That’s good news for domestic solar panels. Residential roofs here tend to be large and structurally sound. The case by type and area:

• Inter-war semis. Epsom, Ewell, Stoneleigh, Banstead, Ashford, Staines, Sunbury and much of Walton and Molesey are built of 1930s semis with hipped roofs and concrete or clay tiles. They take 8–12 panels across two or three faces and are the bread and butter of Surrey solar (semi-detached).
• Post-war and 1970s–80s estates. Goldsworth Park and Sheerwater in Woking, Park Barn and Bellfields in Guildford, the Heatherside and Old Dean estates in Camberley, and Merstham and Horley. Simple gabled roofs with concrete tiles. Easy, good-value installs.
• Large detached houses. Weybridge, Cobham, Esher, Oxshott, Virginia Water, Ashtead and the villages. Big roofs, high electricity use, often an EV or two. These homes suit 6–10kW systems with battery storage. Watch for complex roofs, tall trees and estate rules (detached houses, 5-bed houses).
• Victorian and Edwardian streets. Central Guildford, Woking, Redhill, Reigate, Dorking, Godalming and Farnham have slate and clay-tile terraces and villas. Roofs are smaller and broken up by chimneys, so 6–9 panels is typical (terraced houses, solar on slate).
• Surrey vernacular. Tile-hung cottages, handmade clay roofs and timber frames in Shere, Chiddingfold, Haslemere, Lingfield and the Surrey Hills villages. Many are listed or in conservation areas, and some roofs can’t take standard fixings. An outbuilding or ground-mounted panels is often the better answer (unusual roofs).
• Bungalows. Common in Ashford, Shepperton, Frimley, Bookham and Caterham. Big, low roofs and single-storey scaffolding make them close to ideal (bungalows).
• New builds. Recent estates in Horley, Cranleigh, Ash, Guildford and Woking often already have a few panels and suit an upgrade or a battery. Check any estate covenant (solar on a new build). From March 2027 the Future Homes Standard makes solar a requirement on most new homes in England.
• Flats. Woking and Guildford town centres, Redhill, Staines and Epsom have many blocks. Roof panels need the freeholder’s consent. For a balcony, plug-in solar has been legal since August 2026.

Two Surrey-specific checks. On a private estate, such as St George’s Hill, Burwood Park or Wentworth, the estate company may need to approve anything visible from the road, on top of any planning rules. And if you’re surrounded by tall trees, ask for panel-level optimisers or microinverters to be priced as an option (microinverters vs string inverters).

Best solar panels for Surrey homes

There’s no single best solar panel for Surrey, but the county’s houses point to some clear choices.

At the same wattage, the mainstream brands produce almost identical output. The differences are in the warranty, the look and the company behind it. Our full ranking is in best solar panels UK, with most efficient solar panels and types of solar panels for more detail.

Solar panel installation in Surrey: what to expect

Once the paperwork is done, a home solar panel installation in Surrey is quick. Most solar panel installations follow the same order:

1. Survey and design. The installer measures the roof, checks the structure and consumer unit, runs a shade analysis and sends a fixed, itemised quote.
2. Planning check. If the building is listed, consent comes first. In a conservation area or the Surrey Hills, the installer confirms the design stays within permitted development.
3. Grid application. For most systems above 3.68kW, and almost all battery systems, the installer applies to the network operator before fitting (see the network operators).
4. Scaffolding. It goes up a day or two before the install.
5. Installation. Panels, inverter and any battery are fitted in one to two days for a typical home, or two to three for a large detached house.
6. Handover. You get an MCS certificate, an electrical certificate and the monitoring app. You then register for export payments.

From accepting a quote to switch-on, allow four to eight weeks, with the grid application the main variable (how long installation takes, how panels are installed, best time to install).

What makes it a sustainable solar panel installation?

If you’re choosing solar for environmental reasons, three things make the difference. Size the system to what you’ll use, so less is exported at a low rate. Choose panels with long warranties, so they don’t need replacing early. And ask how old panels and packaging are recycled. A typical panel pays back the energy used to make it in about one to three years and then generates clean power for 25 years or more (benefits of solar panels). Whoever you choose, make sure they are MCS-certified. Without the MCS certificate, you can’t be paid for the electricity you export.

Solar panel quotes in Surrey: what a good one includes

Solar panel quotes in Surrey vary a lot for the same house, and the cheapest isn’t always the best value. A proper quote should have all of this in writing:

• The make and model of the panels, inverter and any battery, not just “Tier 1 panels”.
• The number of panels and the total system size in kW.
• A shade analysis and a yearly output figure in kWh, worked out for your roof.
• Scaffolding, bird mesh, optimisers and the grid application, each shown as included or priced.
• The product warranties and the length of the workmanship guarantee.
• The deposit, which should be protected, and the payment stages.
• A price that stays open for at least 30 days.

Be wary of a quote given over the phone from a satellite image alone, a big discount for signing today, or a savings figure with no working shown (solar panel scams). If you want to pay monthly, read how to finance solar first.

Solar Together Surrey: how it works, and reviews

Solar Together Surrey is the county’s group-buying scheme. Surrey County Council runs it with the 11 district and borough councils and a private company called iChoosr. Residents register for free, approved installers bid in a reverse auction, and you get a personal offer with no obligation to accept.

Solar Together Surrey reviews: is it any good?

It’s a real, council-backed scheme, not a sales trick, and for many households it has been a simple way to get a fair price. The reviews you’ll find online are mixed, and the complaints tend to be about the same things:

• You don’t choose the installer or the kit. The auction winner fits every job in the round, with one specification.
• Installs come in batches. People who register early can wait many months, and some earlier rounds elsewhere in the country were reported to run late.
• The survey usually happens after you accept. The offer is based on what you entered online, so the price or design can change once someone sees the roof.
• Aftercare goes through the installer, who may be based a long way from Surrey.

Our view: it’s a useful benchmark. If a round is open, register, since it costs nothing. Then compare the offer with a quote from a local MCS installer who has surveyed your roof. A local firm will often match the price, fit sooner and let you choose the panels.

Surrey County Council solar panels, grants and free solar panels

People search for “Surrey County Council solar panels” expecting the council to fit or fund them. It does neither for most homeowners. What it does offer, as of October 2026:

• Warm Homes: Local Grant. This is the route to free solar panels in Surrey, and it’s means-tested. Surrey has £14 million to spend and the scheme opened on 2 October 2025. You need a household income of £36,000 or less, or to receive certain benefits or live in an eligible postcode. The home must be privately owned, by you or your landlord, and rated EPC D–G. It can pay up to £15,000 for insulation and solar panels and up to £15,000 for low-carbon heating. Apply through the county council or call 01483 404505.
• A warning from the council. Surrey County Council says it does not cold call about this grant. Anyone who phones or knocks offering a “free council solar survey” is not from the council.
• Home Energy Advice Team. Free in-person energy advice and thermal imaging, run with Zero Carbon Guildford and open to Surrey residents.
• Home energy one-stop shop. The council works with a company called Furbnow, which draws up a home energy plan and manages vetted installers, with a discount for Surrey residents.
• Energy Advice Tool. A free online tool on the council’s website that shows which grants you might qualify for.
• The council’s own buildings. Surrey County Council aims to be net zero as an organisation by 2030 and for the county by 2050. In July 2024 it approved a £6 million programme to cut energy costs at schools, starting with five (solar panels for schools).
• ECO4. All ECO4 work nationally must be finished by 31 December 2026, so this route is effectively closed to new applicants (ECO4 solar).

For most Surrey homeowners there are no free solar panels and no solar panel grants. What everyone does get is 0% VAT until 31 March 2027 (then 5%), export payments through the Smart Export Guarantee, and the £7,500 Boiler Upgrade Scheme grant if you add a heat pump (heat pump and solar). For solar financing, see how to finance solar. Full detail: free solar panels, who actually qualifies, solar grants UK and battery grants.

Planning: Surrey Hills, Green Belt and the new councils

Most Surrey houses can have roof panels under permitted development with no application, provided the panels sit no more than 200mm proud of a pitched roof (or 0.6m above a flat roof), don’t rise above the highest part of the roof and the building isn’t listed. The local picture:

• Who decides. Until 31 March 2027, your district or borough council is the planning authority: Elmbridge, Epsom and Ewell, Guildford, Mole Valley, Reigate and Banstead, Runnymede, Spelthorne, Surrey Heath, Tandridge, Waverley or Woking. On 1 April 2027 all of them, and the county council, are replaced by two new councils. East Surrey takes Elmbridge, Epsom and Ewell, Mole Valley, Reigate and Banstead, and Tandridge. West Surrey takes Guildford, Runnymede, Spelthorne, Surrey Heath, Waverley and Woking. The planning rules stay the same, but expect websites and contact details to change.
• Surrey Hills National Landscape. It covers about a quarter of the county, from Farnham and Haslemere across to Oxted. Roof panels on ordinary houses remain permitted development here. Panels on a wall facing a road need permission, and ground-mounted systems face tighter rules. In September 2026, Natural England submitted plans to extend the protected area by 129 square kilometres, about 30%. That hasn’t been confirmed yet, so nothing changes until it is. The High Weald National Landscape also reaches into the south-east corner of the county.
• Green Belt. Most of Surrey outside the towns is Green Belt. It restricts new buildings, not panels on an existing roof, so it makes no difference to a normal home installation. It does matter for ground-mounted arrays and solar farms.
• Conservation areas. Surrey has about 200. Roof panels on an unlisted house are generally still permitted development. A rear slope is the safe choice. Some conservation areas have extra local controls, so check with the council before ordering (solar in conservation areas).
• Listed buildings. Surrey has more than 6,000. Listed building consent is always needed, and buildings in the grounds of a listed building need it too (solar on listed buildings).
• Private estates and covenants. Estate rules are separate from planning. Check your deeds.
• Flats. Blocks have the same roof rights as houses. The hurdle is the freeholder’s consent.

The network operators: UK Power Networks and SSEN

Surrey is split between two electricity network operators, and which one you have decides who your installer applies to.

The boundary doesn’t follow council lines, so check your bill if you live near it. The limit applies to the inverter, not the panels, so a 4kW or 5kW array on a 3.68kW inverter still counts as a notify-only job. Some approvals come with an export limit, which caps what you sell, not what you use. Older terraces and semis sometimes share a looped supply with next door. It has to be separated before a battery or large system goes in, which the network operator normally does at no cost, but it adds a few weeks. Once connected, register for export payments with any Smart Export Guarantee supplier (SEG tariffs compared, solar and smart meters).

Solar battery installation and storage in Surrey

For most Surrey households, a battery is worth it. This is a commuter county, so many houses are empty during the day while the panels are generating. A 4kW south-facing roof exports about 1,900–2,100kWh a year without storage. A 5–10kWh battery at £3,500–£5,500 lifts the share you use yourself from around 50% to 75–85%. With winter charging on a cheap off-peak tariff, solar battery storage is worth about £310–£440 a year (off-peak charging, Intelligent Octopus Go). Payback on the battery alone is about 9–12 years.

Surrey’s larger homes often justify more. With an EV, a heat pump or electricity use above 6,000kWh a year, look at 10kWh or more (10kWh batteries, what size battery). A solar battery installation can be done with the panels or added later to an existing system, and in the more rural parts of the county, backup power in a power cut appeals to some (battery backup). See are solar batteries worth it, adding a battery to existing panels, best solar batteries and solar, battery and EV charger.

Solar panel maintenance, repair and inverters in Surrey

Many Surrey systems date from the Feed-in Tariff years of 2010 to 2019. They are now at the age when parts need attention. If you already have panels:

• Solar panel repair. If generation has dropped or stopped, start with the inverter display and the isolators, then call an MCS electrician. Most solar repairs turn out to be the inverter, a connector or an isolator, not the panels themselves (solar panels not working, repairs).
• Solar inverters. The inverter is the part most likely to fail, usually after 10–15 years. A replacement costs £800–£1,500 fitted, and it’s a good moment to switch to a hybrid inverter if you want a battery later (inverter replacement, inverter faults, how long inverters last, hybrid inverters).
• Solar PV maintenance and service. Panels have no moving parts, but a service every few years to check the inverter, isolators, cabling, roof fixings and monitoring is sensible. Expect £100–£200 (servicing, solar panel maintenance).
• Solar panel inspection. Worth having before you buy a house with panels, after storm damage, or when a system reaches ten years old. It should include an electrical test and a look at every fixing and cable run.
• Roof work. If the roof needs repair under the panels, removal and refitting costs £500–£1,200 (removal and reinstallation).
• Solar hot water. Older Surrey homes often have solar thermal panels for hot water, which are a different technology and need a heating engineer, not a solar PV installer (solar thermal vs solar PV, immersion diverters).

Residential solar panel maintenance tips for Surrey homeowners

• Watch the trees. A tree that cleared the roof ten years ago may shade it now. If summer output is falling year on year, look up before you call anyone.
• Check after autumn. Leaves and moss collect along the bottom edge of panels and in gutters under them. Clear gutters from a ladder, not the roof.
• Read your generation monthly. Compare each month with the same month last year. A sudden drop means a fault. A slow one means dirt or shade (monitoring).
• Look at the inverter. A green light is good. A red or flashing one, or a fault code, needs a call.
• Keep the paperwork. MCS certificate, warranties and any Feed-in Tariff documents. You’ll need them to sell the house.

Pigeon proofing, solar panel bird protection and cleaning in Surrey

Pigeon proofing solar panels. Pigeons nest under solar panels across Surrey’s towns, and squirrels are a problem too in the leafier parts of the county, where they chew the cables. Solar panel bird protection means fixing a mesh skirt around the edge of the array, with no drilling into the panels. It costs £300–£900 to retrofit and much less if fitted at install, so ask for it on your quote (bird-proofing, pigeons under solar panels).

Solar panel cleaning. On a pitched roof, rain does most of the work. In Surrey the usual reasons to clean are tree sap, pollen, lichen and bird droppings, all more common under trees. A professional clean costs £80–£200. It should use deionised water and soft brushes, never a pressure washer (do solar panels need cleaning).

Commercial solar panel installation in Surrey

Surrey has one of the strongest local economies in the country, with a lot of offices, laboratories, warehouses and light industrial units that use power in the daytime. The main sites are the Surrey Research Park and Slyfield in Guildford, Brooklands in Weybridge, Yorktown and Watchmoor Park in Camberley, Holmethorpe in Redhill, the business parks around Leatherhead, The Causeway in Staines and Dunsfold Park near Cranleigh.

Benefits of commercial solar for Surrey businesses

• Electricity you generate costs a fraction of grid power and isn’t exposed to price rises.
• Commercial solar PV panels typically cost £450–£1,000 per kW at scale and pay back in four to seven years.
• It cuts reported carbon emissions, which more customers and lenders now ask about.
• Roof space that earns nothing starts to pay.

The commercial solar installation process in Surrey

1. Data. A year of half-hourly meter data shows when you use power.
2. Survey. A structural check of the roof and an electrical survey.
3. Design. The system is sized to your daytime use, not to the size of the roof.
4. Grid application. Larger systems need the network operator’s approval, which can take two to three months.
5. Consents. Landlord’s consent if you lease, and a check with the council’s planners for large arrays or listed buildings.
6. Installation. Usually one to four weeks, with the business running throughout.

Financing and tax incentives for business solar in Surrey

Companies can normally claim the full cost against profits in the first year through the Annual Investment Allowance or full expensing. Onsite solar and batteries are exempt from business rates until 2035. If you’d rather not pay up front, asset finance spreads the cost, and a power purchase agreement lets an investor fund the system while you buy the power at an agreed rate. Take advice from your accountant on which suits you.

Commercial solar battery systems and storage

A commercial solar battery system makes sense where you generate more than you use at midday, or where you pay high charges for peak-time power. Batteries let you store cheap or free power and use it in the late afternoon. The case depends on your tariff, so ask for it to be modelled both ways.

Schools, churches, care homes and farms in the Surrey Hills are good candidates too. See commercial solar panels, solar panels for schools, solar for farms and solar carports.

Solar farms in Surrey

Surrey has little large-scale solar, because so much of it is Green Belt or protected landscape. The projects people ask about:

• University of Surrey solar farm. A 12.2MW ground-mounted solar facility on three fields of university land west of Guildford, built with SSE Energy Solutions. Guildford Borough Council approved it on 7 November 2024. It’s designed to supply about a third of the university’s electricity through a private wire to the Stag Hill campus, and the university said it would lift Surrey’s renewable generating capacity by 13%. It was due to go live in 2025. We couldn’t confirm the switch-on date.
• Floating solar panels at Walton-on-Thames. The Queen Elizabeth II Reservoir carries more than 23,000 floating solar panels, 6.3MW in all, covering about a tenth of the water. Thames Water commissioned it in March 2016, when it was described as the largest floating solar farm in the world.
• Little Flanchford Farm, Leigh. Mole Valley District Council approved a solar farm here, expected to power about 5,500 homes for up to 40 years, after a debate about the loss of good farmland.
• Ashford. We couldn’t find a current solar farm application for Ashford in Surrey. Most news about an “Ashford solar farm” is about Ashford in Kent.

For planning applications, search the planning register of the district or borough council that covers the site.

Solar panel companies in Surrey

There are plenty of solar panel companies in Surrey to choose from. They fall into four groups, and each suits a different buyer.

Several local firms have “Surrey” and “solar” in their names, and people search for them directly. We don’t rank or review individual solar companies in Surrey here, because we can’t inspect their work. Whichever solar company you’re looking at, the same checks apply, and a good firm offering solar panel services will be happy to answer all of them.

Solar panel installers in Surrey: how to choose

A good local solar panel installer in Surrey will usually beat a national by £1,000–£2,000 on the same specification. They’ll also know which network operator covers your street, how your council treats conservation areas and the Surrey Hills, and how to work on clay tiles, and they’ll be close enough to come back if something needs attention.

The best solar installers in Surrey aren’t the ones with the biggest adverts. They’re the ones who survey properly, name every part in writing and are still trading in ten years. Whether you’re comparing solar PV installers, solar experts or a one-man electrician, run the same checks:

• They’re on the MCS register under their exact trading name.
• They’re a member of HIES or RECC.
• They’ve been trading for three years or more at Companies House.
• The panel, inverter and battery are named in writing.
• The quote includes a shade analysis and a realistic output figure.
• They check the planning position and handle the network application.
• They’ve fitted on your type of roof before, and can show you photos.
• You get a ten-year insurance-backed workmanship guarantee.
• There’s no “today only” pricing.

Pay any deposit by credit card for extra protection. How to choose a solar installer is the full checklist.
