Commercial Solar in Edinburgh: Scotland's Capital for Clean Energy
Edinburgh's commercial property market encompasses some of the most diverse building types in Scotland — from the glass-and-steel campuses of Edinburgh Park to the Victorian industrial heritage of Leith Docks and the modern logistics parks of Newbridge and Livingston. Across all these typologies, the case for commercial solar has strengthened significantly in recent years: Scottish electricity prices now match or exceed the UK average, Scotland's NPF4 planning framework is the most solar-friendly in the UK, and Business Energy Scotland offers free energy advice and grant signposting for Scottish SMEs.
Edinburgh businesses benefit from one additional advantage: SP Distribution's G99 connection process, while slightly more complex than some other DNOs, has shorter queue times than the heavily loaded NGED and UK Power Networks territories in England. We have successfully commissioned commercial solar systems at Edinburgh Park, Newbridge, and Bathgate, and our team is familiar with SP Distribution's specific protection relay requirements and SEF commissioning standard.

| Bathgate Industrial | EH48 | Engineering, fabrication | SPEN Central Scotland | High — varied roof types |
| Easter Bush | EH25 (Midlothian) | Research, agri-science | SPEN Central Scotland | High — rural, no shading |
| Leith Docks | EH6 | Mixed commercial | SPEN Central Scotland | Moderate — heritage constraints |
| Sighthill Industrial | EH11 | Trade, light manufacturing | SPEN Central Scotland | Moderate — older units |
SP Distribution: G99 Process in Edinburgh
All Edinburgh commercial solar systems above 11kWp three-phase require a G99 application to SP Distribution (SP Energy Networks). Key differences between SP Distribution and the more commonly referenced NGED process:
- SP Distribution requires inverter protection relay settings to match SPEN's published technical schedule (available on SPEN Connections portal)
- From January 2026, all new grid-connected solar systems in SPEN territory must incorporate Smart Export Functionality (SEF) — automatic remote disconnection capability. All inverters we specify are SEF-compliant.
- SPEN operates a pre-application advice service for systems above 100kWp — useful to identify connection constraints before design finalisation
- Commission witness testing is required in SPEN territory for all G99 systems — our engineers are available for joint commissioning with SPEN's technical team
Typical SPEN G99 timeline for Edinburgh urban applications: 8–16 weeks from application submission to commissioning clearance. We submit applications at contract signature to run in parallel with procurement.
Scottish Grants and Incentives for Edinburgh Solar
Business Energy Scotland (BES)
Business Energy Scotland, managed by the Energy Saving Trust on behalf of the Scottish Government, offers free energy audits for Scottish SMEs followed by grant support for qualifying renewable energy projects. Grants of up to £10,000 are available for SMEs with fewer than 250 employees, rising to £20,000 for community-benefit projects. BES also provides interest-free loans of up to £500,000 for larger installations. We assist with BES applications as part of our Scottish commercial solar service.
Annual Investment Allowance (UK-wide)
The AIA provides 100% first-year tax relief on the full capital cost of commercial solar for all UK businesses. For an Edinburgh company installing a 120kWp system for £85,000, AIA saves £21,250 in Corporation Tax in year one — reducing the effective investment to £63,750. At 870 kWh/kWp irradiance, the system generates 104,400 kWh/year, saving approximately £22,968/year at 22p/kWh. Payback after AIA: 2.8 years.
Case Study: 120kWp NHS Scotland Administration Building, Edinburgh
An NHS Scotland administrative and training facility in West Edinburgh (EH12) installed a 122kWp rooftop system in April 2025:
- 308 × 395Wp bifacial panels on south-facing pitched roof (32° pitch)
- 2 × 60kW SMA Sunny Tripower CORE2 inverters
- G99 to SP Distribution — approved in 13 weeks including SEF requirement sign-off
- Business Energy Scotland grant of £15,000 (18% of capital cost)
- Total net cost after grant and AIA: £46,550
Year-1 performance: 105,000 kWh generated. Avoided cost: £23,100 at 22p/kWh. NHS Scotland estate carbon reporting: 21.7 tCO₂ displaced. Net payback on effective investment: 2.0 years.

Frequently Asked Questions
Who is the DNO for Edinburgh commercial solar?
Edinburgh is served by SP Energy Networks (SPEN) — specifically SP Distribution, the licensed DNO for Central Scotland and southern Scotland. SP Distribution's central operations are based in Perth. G99 applications for commercial solar systems above 50kWp in Edinburgh and the Lothians are processed by SPEN's Distributed Generation team and typically take 8–16 weeks, depending on the existing connection capacity at the local 11kV substation serving the site.
Does Scottish planning policy support commercial solar?
Scotland's National Planning Framework 4 (NPF4) is one of the most pro-renewable planning policies in the UK, with a presumption in favour of wind and solar energy development. Edinburgh City Council's Local Development Plan 2 (LDP2) supports renewable energy across all zones. Scottish Permitted Development rights for non-domestic solar under the Town and Country Planning (General Permitted Development) (Scotland) Order 1992 are broadly equivalent to English PD rights, with the same 1MWp threshold for roof-mounted systems.
Are there Scottish-specific grants for commercial solar?
Yes. Scottish businesses can access: (1) Business Energy Scotland — managed by Energy Saving Trust Scotland, offering free energy audits and grant support for SMEs; (2) CARES (Community and Renewable Energy Scheme) — administered by Local Energy Scotland, primarily for community-owned projects but accessible to businesses with community benefit elements; (3) the UK-wide IETF for large energy-intensive manufacturers; (4) the Annual Investment Allowance for 100% first-year tax relief. Scottish Enterprise may also support larger renewable energy capital projects through Regional Selective Assistance.
What is the irradiance for Edinburgh — worth installing solar?
Edinburgh receives approximately 870 kWh/kWp of solar irradiance per year — lower than the UK average of 950 kWh/kWp but still commercially viable. A 100kWp system in Edinburgh generates approximately 87,000 kWh/year, compared with 95,000 in Cardiff or 100,000 in Bristol. The lower irradiance is partially offset by cooler operating temperatures — solar panels are more efficient at lower temperatures, and Edinburgh's cooler summers mean panels operate closer to their rated performance than in the South East. At current electricity prices of 22–28p/kWh, Edinburgh solar still delivers sub-5 year payback for commercial installations.
Which Edinburgh business parks are active for solar?
Edinburgh Park (EH12) — a major purpose-built business park in the west of the city — is the primary zone for large commercial solar in Edinburgh. Newbridge Industrial Estate (EH28), Livingston South (EH54), and Bathgate Industrial Estate (EH48) are active areas in the wider Edinburgh City Region. Easter Bush campus (Midlothian) hosts several large agricultural and research buildings with solar potential. The Royal Mile area and the New Town have listed building constraints that preclude most rooftop solar, but commercial premises in non-conservation zones face no heritage restrictions.
How does SP Distribution G99 differ from NGED G99?
The underlying G99 technical standard is the same UK-wide, but SP Distribution has some operational differences: (1) SP Distribution operates a 'fast track' notification process for systems below 50kWp per phase; (2) their protection relay specifications are slightly different to NGED and Western Power, requiring inverter protection settings to be verified against SPEN's published schedule; (3) SP Distribution requires all commercially installed systems to use SEF (Smart Export Functionality) from January 2026. We are familiar with SPEN's technical requirements and have commissioned multiple commercial systems in EH and ML postcodes.
Can Edinburgh businesses export solar electricity to the grid?
Yes. Scottish commercial solar operators qualify for the Smart Export Guarantee (SEG), which requires licensed electricity suppliers to offer export tariffs. SEG rates in 2026 range from 3p/kWh (Octopus Energy baseline) to 6.5p/kWh (OVO Energy fixed export). For larger systems above 1MWp, direct Power Purchase Agreements (PPAs) with energy trading companies often deliver better rates — 8–12p/kWh on longer-term contracts. We advise on SEG vs PPA based on system size, export volume, and client preference.
