Commercial building solar panels in Leamington Spa
Commercial roofs in Leamington Spa tend to be flat, membrane covered and cluttered with plant, which shapes the layout more than the size does. We check the covering and the lease together, because a roof with eight years of membrane left and a tenant with a break in three changes the answer.

Commercial rooftop solar across Warwickshire
Yield on a Leamington Spa commercial roof
Modelled irradiation here is 1,127 kWh per square metre a year on a low-tilt array, which works out at 880 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is within a few percent of the mean across the towns we cover, so the weather is not what decides the case here. Opening hours are.
How many commercial buildings Warwick has
On the Valuation Office Agency's count, Warwick holds 1,280 retail and 1,390 office properties on the rating list. By office stock the district sits above the median of the 318 districts in England and Wales; by retail stock it sits above the median of the 318 districts in England and Wales.
The big roofs are in the 40 large-format retail units, superstores and retail warehouses in the district, about 84,000 square metres of floorspace under largely single storey roofs.
The same list carries 250 hotel, leisure and assembly properties in the district. Leisure centres and hotels run seven days a week, which puts weekend generation to use that an office would export.

Leamington Spa ranks 4 of 7 towns we cover in Warwickshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 866 to 893, a spread of 27 kWh per kWp. Within Warwickshire 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
Connections around Leamington Spa are handled by National Grid Electricity Distribution, which sets the export limit for the site. Above 3.68 kW per phase the connection runs under G99, so the export limit is agreed in advance rather than assumed. Where the local network is constrained, an export-limited connection usually still makes the scheme work, because a commercial building uses most of what the roof makes during the working day.
Across Warwickshire the planning database records 94 solar schemes totalling 1201 MW, of which 18 are operational (REPD Q1 2026).

Questions about solar in Leamington Spa
- What would a 210 kWp array produce in Leamington Spa?
- Yes. At 880 kWh per kWp a year, a 210 kWp array on a Leamington Spa roof models at around 185,000 kWh. What changes the answer is how much of that the building uses during opening hours rather than exports. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Do we need planning permission for solar on a commercial building in Warwick?
- Usually not a full application. In England, panels on the roof of a non-domestic building are permitted development under Class J of Part 14 of the General Permitted Development Order, with no capacity cap since December 2023. Above 50 kW, which covers most commercial arrays, you must first apply to Warwick for a determination on prior approval of the design and appearance, in particular glare on neighbouring land. On a flat roof panels may stand no more than 1 metre above the roof and must sit at least 1 metre from its edge, and listed buildings and scheduled monuments are excluded. See our planning permission guide for the detail.
- Does solar help a Leamington Spa landlord meet MEES?
- It can. A non-domestic EPC is an asset rating, and on-site generation counts in the calculation, so an array usually lifts the score. Let property in England and Wales must be EPC E or better today. The government's interim response of 18 June 2026 proposes EPC B, where cost effective, from 2031 for let buildings over 1,000 m², and drops the EPC C step once planned for 2027. How far solar moves a particular building depends on its fabric and services, which is why the EPC assessor models it before anything is fitted.
- Which network operator handles the connection in Leamington Spa?
- Capacity varies street by street and only National Grid Electricity Distribution can answer it for your connection. We ask early, because an export-limited offer changes the design rather than ending the scheme, and most commercial buildings use most of what they generate anyway.
