Commercial solar in Luton

Solar in Luton in figures

What the figures show

Capacity in Luton has grown by 133% since the end of 2020, faster than the UK as a whole (69%). In 2025 alone it rose from 10.3 MW to 11.6 MW.

There are 35.9 installations for every 1,000 households, below the East of England median of 73.8 and below the UK median of 67.0. That is 312th of 361 council areas, and 42nd of 45 in East of England.

At 4.1 kW on average, most installations here are home-sized, so business roofs make up a small share of what is installed so far.

What a business roof in Luton could generate

Modelled with PVGIS for the centre of Luton, a south-facing roof at 30 degrees produces about 1,016 kWh per kWp a year. That is 139th of 361 council areas; the UK median is 998 kWh.

Same sums as our commercial solar calculator: illustrative, not a quote. East- or west-facing roofs, shading and how much power you use in daylight all move these figures, and a company paying corporation tax can usually shorten the payback with capital allowances. See the cost guide for price ranges by system size.

Planning and grid connection

Luton follows the national planning rules for England. Permitted development rights for non-domestic rooftop solar were widened in December 2023, including removal of the old 1 MW limit, but conditions still apply, especially for listed buildings and conservation areas. Ground-mounted arrays and carports usually need an application to the council, or to a national park authority inside a national park. Our planning permission guide sets out the conditions.

Most commercial systems need G99 approval from the local network operator before they are switched on. The operator follows the postcode rather than the council boundary: our East of England page covers the operators in the region, and the Energy Networks Association postcode tool confirms yours. See G99 and DNO applications.
