Solar panels for warehouses in Cheltenham
Roof space is the one asset a Cheltenham unit already owns and rarely uses. What decides a scheme here is the state of the covering and the load path, which is why the survey starts on the roof rather than in a spreadsheet.

Warehouse rooftop solar across Gloucestershire
What a roof in Cheltenham actually generates
Modelled irradiation at this latitude is 1124 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 879 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That sits within a few percent of the mean across the towns we cover, so the case rests on your consumption pattern rather than on the weather.
Distribution stock around Cheltenham clusters on M5 J10, M5 J11 and A40, which is where the large single-let roofs are.
Most of the units we look at here sit in the GL postcode area.
Cheltenham is the planning authority for most sites here, and the built-up area holds a population of about 115,940, the size that tends to be served by mid-box last-mile units rather than national hubs (ONS Census 2021 built-up areas).
Cheltenham ranks 4 of 6 towns we cover in Gloucestershire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 870 to 905, a spread of 35 kWh per kWp. Within Gloucestershire that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.
Grid connection through National Grid Electricity Distribution
National Grid Electricity Distribution operates the distribution network across Gloucestershire, so the export application goes to them. Anything larger than 3.68 kW per phase falls under G99, which means an application before commissioning rather than a notification afterwards. A constrained network is not the end of a scheme. Capping export costs little when the building already absorbs most of what the roof produces.
Across Gloucestershire the planning database records 207 solar schemes totalling 1592 MW, of which 39 are operational (REPD Q1 2026).

Questions about solar in Cheltenham
- Is there enough sun in Cheltenham to make this work?
- Modelled at 879 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 440,000 kWh a year before shading. That array needs about 1,485 sqm of clear roof once walkways and setbacks are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Who do we apply to for export in Cheltenham?
- Capacity varies street by street, and only National Grid Electricity Distribution can answer it for your connection. We ask the question early, because an export-limited offer changes the design rather than killing the scheme.
- Do we need planning permission in Cheltenham?
- In most cases no, because roof-mounted panels on commercial buildings sit within permitted development. The exceptions are listed buildings, conservation areas and arrays that stand proud of the roof plane. We check with Cheltenham first either way.
- Has anyone near GL50 already done this?
- The planning database records 3 solar schemes in this postcode district, 3 of them roof mounted. That matters less as proof that it works and more as evidence of how the local network has been treating export applications. Source: Renewable Energy Planning Database, Q1 2026.
