Solar panels for warehouses in Leatherhead
A Leatherhead warehouse roof sits idle through exactly the hours its occupier buys the most expensive electricity. 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.
910 kWh per kWp a year at this latitude, so a 500 kWp array models at about 455,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in Leatherhead actually generates
Modelled irradiation at this latitude is 1167 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 910 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 Leatherhead clusters on M25 J9, A24 and A243, which is where the large single-let roofs are.
Surveys run across KT postcodes, KT22 outward.
Mole Valley is the planning authority for most sites here, and the built-up area holds a population of about 11,485, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
Leatherhead ranks 3 of 10 towns we cover in Surrey on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 900 to 916, a spread of 16 kWh per kWp. Within Surrey 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
UK Power Networks operates the distribution network across Surrey, 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 Surrey the planning database records 74 solar schemes totalling 182 MW, of which 6 are operational (REPD Q1 2026).

Questions about solar in Leatherhead
- Is there enough sun in Leatherhead to make this work?
- Modelled at 910 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 455,000 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 Leatherhead?
- Capacity varies street by street, and only UK Power Networks 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 Mole Valley?
- 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 Mole Valley first either way.
