Solar Panels in Surrey: Costs, Savings & Installers
Surrey homeowners are well placed to benefit from solar. The county sits in the South East, the UK's leading region for solar installations, and its roofs receive more sunlight than most of the country. This guide sets out what a Surrey homeowner needs to know before getting quotes: what a system costs, how much electricity it is likely to produce, where planning rules are stricter, which support schemes apply locally and how to choose an installer you can trust. ## Key stats for Surrey - 305,101 - solar installations across the South East by July 2026, the most of any UK region - 900-1,000kWh - typical annual output per kWp on a well-sited Surrey roof - £7,000-£10,000 - typical cost of a 4-5kWp system for a three-bedroom home - 0% VAT - on qualifying solar and battery installations until 31 March 2027 - 11 - district and borough councils across Surrey, each with its own planning team ## Is Surrey a good place for solar panels? Yes. Southern England receives more sunlight across the year than the Midlands, the North or Scotland, and a well-sited Surrey roof can expect around 900 to 1,000kWh of electricity per kWp each year. That puts a typical 4kWp system at roughly 3,600 to 4,000kWh, more than the [ 2,500kWh a year ](https://www.ofgem.gov.uk/sites/default/files/2026-06/Summary-of-changes-to-energy-price-cap-1-July-to-30-September-2026-revised-TDCV.pdf) Ofgem uses as typical electricity use for a medium household. Homeowners across the region have noticed. Government figures published in August 2026 show the [ South East leads every UK region for solar ](https://www.gov.uk/government/news/first-regional-solar-breakdown-as-installations-hit-record-highs) , with 22,628 installations in the first seven months of the year and 305,101 in total. ### Typical output for a Surrey homeRoof direction

South-facing

South-east or south-west
3,400-3,800kWh
East or west-facing

*These figures assume an unshaded roof pitched at around 30-40°. They are indicative, not a forecast for your home. The* [ * Energy Saving Trust * ](https://energysavingtrust.org.uk/) *estimates that east or west-facing systems collect around 15-20% less energy than south-facing ones.* Shade deserves particular attention in Surrey, one of England's most wooded counties. Mature trees in gardens and along roads in towns such as Weybridge, Cobham and Haslemere can cut winter output noticeably. A good installer will assess shading at the survey stage and may recommend panel-level optimisers. ## How much do solar panels cost in Surrey? Installation prices in Surrey are close to the national picture. Access is the main local variable: three-storey townhouses, steep or complex roofs and properties on narrow lanes can need more scaffolding, which adds to the bill.Property and usage

Homes where someone is in during the day, or with an electric car or battery, can raise the share used at home. That shortens the [ solar panel payback period ](https://gosolartoday.co.uk/articles/solar-panel-payback-period) . ## Do you need planning permission for solar panels in Surrey? Usually not. In England, panels fitted to the roof of a house normally count as permitted development, provided they project no more than 200mm from the roof slope, stay below the highest part of the roof and are positioned to limit their visual impact. Surrey has more protected places than most counties, so a few exceptions come up often: - **Listed buildings:** always need listed building consent, and panels on a listed building or within its grounds need planning permission. This is worth checking early if you own one of Surrey's many period cottages or farmhouses. - **Conservation areas:** roof-mounted panels are usually still permitted, but panels on a wall facing a road are not. Some Surrey conservation areas also have Article 4 directions that remove permitted development rights, so check before you commit. - **Surrey Hills National Landscape:** around a quarter of the county sits within this protected landscape. Roof-mounted panels on homes are generally still permitted development, but ground-mounted arrays and panels on prominent outbuildings may face closer scrutiny. Your installer should flag any concerns at the survey. If you are unsure, the [ Planning Portal ](https://www.planningportal.co.uk/) explains the national rules, and a Lawful Development Certificate from your council provides certainty before work starts. ### A change to Surrey's councils in 2027 Planning decisions in Surrey currently sit with the 11 district and borough councils. From 1 April 2027, they will be replaced by [ two new unitary councils ](https://www.surreylgrhub.gov.uk/homepage/15/decision-on-local-government-reorganisation) : East Surrey, covering Elmbridge, Epsom and Ewell, Mole Valley, Reigate and Banstead and Tandridge, and West Surrey, covering Guildford, Runnymede, Spelthorne, Surrey Heath, Waverley and Woking. Existing conservation areas and planning policies are expected to carry over during the transition, but any application made after that date will go to the new council for your area.
