Commercial building solar panels in St Neots
A flat commercial roof in St Neots is usually the largest surface a building owns and the one nobody is asked to manage. What decides a scheme is the roof covering, the parapet height and the plant layout, which is why the survey happens on the roof rather than from a satellite image.

Solar PV for commercial property across Cambridgeshire
What a flat roof in St Neots generates
Modelled irradiation here is 1,150 kWh per square metre a year on a low-tilt array, which works out at 898 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.
Commercial stock in Huntingdonshire
Huntingdonshire has 1,080 office premises and 1,010 shops and other retail premises on the non-domestic rating list, according to the Valuation Office Agency. By office stock the district sits above the median of the 318 districts in England and Wales; by retail stock it sits below the median of the 318 districts in England and Wales.
The big roofs are in the 50 large-format retail units, superstores and retail warehouses in the district, about 90,000 square metres of floorspace under largely single storey roofs.
The same list carries 310 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.

Commercial rooftop solar already planned near St Neots
The Renewable Energy Planning Database records one roof-mounted scheme on office and business park buildings in this postcode district. These are other organisations' projects, listed from the public record, not ours.
| Scheme | Applicant | Type | Capacity | Status |
|---|---|---|---|---|
| Chester Road, Colmworth Business Park | Lattice Labels Limited | office | 0.24 MW | Awaiting Construction |
The built-up area holds about 33,265 people, so the stock here runs to high street premises, a supermarket or two and the odd hotel (ONS Census 2021 built-up areas).
We arrange surveys across the PE postcode area, starting from PE19.
St Neots ranks 8 of 8 towns we cover in Cambridgeshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 898 to 908, a spread of 10 kWh per kWp. Within Cambridgeshire that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.
Grid connection through UK Power Networks
Connections around St Neots are handled by UK Power Networks, 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 Cambridgeshire the planning database records 172 solar schemes totalling 2422 MW, of which 46 are operational (REPD Q1 2026).

Questions about solar in St Neots
- How much would solar on a commercial building in St Neots generate?
- The model gives 898 kWh for every kWp installed here, so 210 kWp is about 189,000 kWh a year before shading losses. Allow roughly 1,390 m² of roof for it. 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 Huntingdonshire?
- 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 Huntingdonshire 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 St Neots 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 St Neots?
- Capacity varies street by street and only UK Power Networks 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.
