Commercial Solar Installation in Surrey
Surrey combines proximity to London's commercial market with excellent solar conditions and a prosperous local economy. The county hosts major corporate headquarters, technology companies, logistics operations serving the South East, and the Heathrow and Gatwick airport corridors. Business parks at Guildford, Woking, Weybridge, and Farnham provide extensive roof space for commercial solar.
Our Surrey teams have installed solar on corporate offices in the Guildford area, logistics facilities along the M25, manufacturing operations in Redhill and Reigate, and business park developments across the county. We understand Surrey's planning landscape, including Green Belt and AONB considerations.
With commercial electricity rates averaging 31p/kWh - among the highest in the UK - and annual solar yields of 940 kWh per kWp, Surrey businesses achieve payback in just 3-4 years. A 100kW system saves approximately £29,100 per year.
Surrey Solar Economics
Surrey's solar irradiance of approximately 1,080 kWh/m² annually produces around 940 kWh per kWp installed. Combined with some of the UK's highest commercial electricity rates, this delivers exceptional financial returns.
Corporate headquarters and technology companies in Surrey benefit from solar through reduced operating costs, improved ESG credentials, and enhanced property values. The county's office buildings achieve high self-consumption ratios during business hours.

Planning Considerations in Surrey
Surrey has extensive Green Belt and AONB (Surrey Hills) coverage. Commercial rooftop solar is typically permitted development even in these areas. Ground-mounted arrays face additional planning scrutiny in Green Belt and AONB locations. Our team handles all planning considerations across the county.
Surrey Commercial Solar FAQs
How do Surrey's high electricity rates benefit solar economics?
Surrey's commercial electricity rates of approximately 31p/kWh are among the highest in the UK. Since solar generates electricity at just 4-5p/kWh over its lifespan, every unit of self-consumed solar electricity saves approximately 26-27p. This massive cost differential drives payback periods of just 3-4 years and 25-year returns exceeding 500% on investment.
Does Green Belt affect commercial solar in Surrey?
Green Belt designation does not prevent commercial rooftop solar installation - most systems qualify for permitted development regardless of Green Belt status. Ground-mounted solar arrays in the Green Belt require full planning permission and must demonstrate very special circumstances. Our team advises on the most appropriate approach for your specific property.
What size systems suit Surrey office buildings?
Surrey's office buildings typically install systems between 30kW and 150kW depending on roof area. A typical office building with 1,500m² of roof space can accommodate a 100kW system generating approximately 94,000 kWh annually. With office hours aligning well with solar generation, self-consumption ratios of 80-90% are common, maximising financial returns.
How does commercial solar improve Surrey property values?
Commercial solar installations in Surrey improve EPC ratings, reduce operating costs, and enhance a building's sustainability credentials - all factors that increase property value. Research indicates commercial buildings with solar installations command 3-7% higher rental premiums and improved lease terms. In Surrey's competitive commercial property market, solar is increasingly seen as a standard building enhancement.
Can Surrey businesses benefit from battery storage alongside solar?
Battery storage enhances commercial solar returns by storing excess daytime generation for use during evening peak rates. In Surrey, where peak electricity rates can exceed 35p/kWh, battery storage adds an additional 8-15p/kWh savings on shifted energy. We design integrated solar and battery systems that optimise self-consumption and provide backup power capability.

Surrey's M25 and Gatwick Corridor: Solar Opportunity
Surrey's commercial property market is dominated by three distinct zones: the M25 corridor (logistics and distribution), the Gatwick Diamond (technology, aerospace and business services clustered around the airport), and the Thames Valley fringe (office and R&D parks extending from Berkshire). Each zone has different electricity demand profiles and solar suitability, but all are characterised by businesses paying premium commercial electricity tariffs that make solar economics particularly compelling.
Distribution network operator boundaries in Surrey are divided between UKPN (UK Power Networks, covering east Surrey and the M25 corridor) and SSEN (Scottish and Southern Electricity Networks, covering west and south Surrey). Understanding which DNO covers your site is important because G99 processing times, connection costs and export limits differ between the two operators. Pre-application enquiries to the relevant DNO are essential for systems over 100kW in Surrey, where substation capacity is sometimes constrained around major commercial clusters.
| Surrey Area | DNO | Key Commercial Sectors | Solar Notes |
|---|---|---|---|
| Guildford/Woking | SSEN | Professional services, retail, NHS | Generally good capacity; pre-app for >100kW |
| Reigate/Redhill/Gatwick | UKPN/SSEN border | Logistics, aerospace, offices | Check DNO boundary carefully |
| Croydon fringe (Purley/Coulsdon) | UKPN | Logistics, retail, commercial | Dense urban; some constraints |
| Leatherhead/Epsom | UKPN | Pharma, business services | Good capacity on A24 corridor |
| Farnham/Camberley (NE Hants border) | SSEN | Defence, technology, logistics | Good rural and edge-of-town capacity |
Surrey businesses benefit from above-average solar irradiance for the UK — typically 1,020-1,060 kWh/kWp/year in the south of the county, making solar generation modelling somewhat more favourable than in the Midlands or North of England. For a Guildford business park office with a 50kW system, annual generation of approximately 51,000 kWh at 80% self-consumption creates savings of around £11,400/year at current tariffs — a payback of under 5 years before AIA relief.
