Grid connection with SP Energy Networks
Glasgow is served by SP Energy Networks through its SP Distribution licence, which covers central and southern Scotland. Commercial systems above the G98 limits need G99 approval before connecting, exactly as in England and Wales. Boundaries can vary at the edges of licence areas, so confirm your operator with the Energy Networks Association postcode tool.
Older industrial estates around the city often have supplies sized for past uses, which can help or hinder depending on how the site has changed. Where export is limited, an export limitation scheme under G100 or a battery can still allow a worthwhile array. Our page on G99 and DNO applications explains the process.
Planning in Glasgow and the Scottish rules
Glasgow City Council decides applications in the city. Several of the region's biggest employment areas are in neighbouring councils:
- Hillington Park, a large industrial estate on the western edge of the city, lies largely in Renfrewshire, as do Glasgow Airport and the Advanced Manufacturing Innovation District Scotland beside it.
- Eurocentral, the logistics and business park beside the M8, is in North Lanarkshire.
- Sites to the south east, such as those around Cambuslang and Blantyre, fall to South Lanarkshire.
Scotland has its own planning system. Its permitted development rights for rooftop solar were widened in 2024, removing the previous 50 kW limit for non-domestic buildings. Listed buildings and World Heritage Sites are excluded, panels on flat roofs must stay within a height limit, and in conservation areas panels generally should not go on principal elevations or roof slopes facing a road. Check the current conditions with the council before relying on them. Conservation areas cover much of Glasgow's historic city centre and West End.
The local economy and solar
Glasgow's economy includes engineering and shipbuilding on the Clyde at Govan and Scotstoun, advanced manufacturing, food and drink, financial and business services, universities, hospitals and logistics along the M8 and M74. Manufacturers with daytime shifts, food and drink producers, distribution centres and large public estates such as hospitals and campuses tend to use most of their generation on site. See our page on factories.
The Low Emission Zone and vehicle charging
Glasgow was the first Scottish city to enforce a Low Emission Zone, with penalties for non-compliant vehicles in the city centre from June 2023. Unlike a Class C zone in England, it applies to most vehicles, including private cars, and it is enforced through penalties rather than a daily charge. At the time of writing the initial penalty is £60, doubling for repeat contraventions up to a cap of £480 for cars and vans and £960 for buses, coaches and HGVs. Check the council's LEZ pages for the boundary and exemptions.
For city centre businesses with deliveries, vans or staff parking, electric vehicles avoid the issue entirely, and a rooftop array can provide much of the daytime charging. Our page on EV charging for business covers how chargers and solar are planned together.
Roofs and buildings in Glasgow
- Victorian sandstone warehouses and tenement-style commercial buildings in the Merchant City and city centre, often listed, with slate roofs and limited usable area.
- Post-war industrial estates across the city and at Hillington, with many 1960s to 1980s units roofed in asbestos cement sheeting; see asbestos roofs.
- Modern distribution sheds at Eurocentral and along the motorway network, with profiled metal roofs.
Glasgow's wet climate makes good drainage around panel rows and safe roof access for cleaning and maintenance worth discussing with the installer.
Expected generation
Glasgow's west coast weather is cloudier than Edinburgh's, so yields are towards the bottom of the UK range. A well-oriented array typically produces about 800 to 860 kWh per kWp a year (indicative). The European Commission's PVGIS model gives close to 855 kWh per kWp for an ideally angled south-facing array with standard losses, and nearer 695 for a low-pitch east-west layout. Savings still depend mainly on how much you use on site and your unit rate.
How the free survey works
Tell us about the site through the short form. We review it and call you to understand the building and how you use power. If it looks suitable we arrange a free survey with one MCS certified installer matched to the site, in person or virtual, and your details go to that installer only. There is no obligation. See our Scotland page for the wider picture.
Frequently asked questions
Do Scottish planning rules differ from England's for rooftop solar?
Yes. Scotland has its own permitted development rules, which were widened in 2024 to remove the 50 kW limit for non-domestic rooftop solar. Listed buildings and World Heritage Sites are excluded, and there are conditions for flat roofs and conservation areas. Glasgow City Council or the relevant neighbouring council can confirm whether your building needs an application.
Is Hillington Park in Glasgow for planning purposes?
Largely not. Most of Hillington Park lies in Renfrewshire, so Renfrewshire Council is usually the planning authority, even though many units have Glasgow postal addresses. Check the council for your exact unit. Most rooftop systems on modern industrial units can proceed under permitted development, subject to the Scottish conditions and your landlord's consent.
Does the Low Emission Zone affect our fleet decisions?
It can. Glasgow's zone applies to most vehicles in the city centre, including cars, and non-compliant vehicles face penalties that rise with repeat entries. If your vans or staff regularly enter the zone, moving to electric removes that risk, and charging from your own solar during the day can lower the running cost.
Is solar worth it in Glasgow's climate?
It can be. Yield here is about 800 to 860 kWh per kWp a year for a well-oriented array (indicative), lower than southern England, but each unit you generate and use saves your full unit rate. Businesses with high daytime demand, such as manufacturers and food producers, usually see the best returns. The survey models your own figures.
