A new call for evidence aims to understand the feasibility of solar carports across England, Wales, and Northern Ireland. Launched by the Department for Energy Security and Net Zero (DESNZ), the call is split into two sections. Section 1 focuses on solar canopies and carparks, while Section 2 focuses on EV infrastructure and planning.
Within the call for evidence, the government is considering requiring solar installations in all new outdoor car parks, as well as retrofitting existing car parks above a certain size. The consultation includes both public and private sector car parks, and is still considering whether multi-storey and residential sites should be within scope.
DESNZ is seeking information on the economic and technical feasibility of installing solar canopies, as well as their impact on local energy networks, potential disruption, and the financial benefits for asset owners and operators.
The call for evidence runs until 20 May 2025, with feedback from car park owners, solar developers, and local authorities of particular interest. Responses could help shape future government policy and may form the basis of a future mandate.
What does this mean for business?
Organisations that own or operate large outdoor carparks could face new compliance requirements in the near future. While a mandate is not yet in place, this call for evidence strongly signals the direction of travel for solar policy in the built environment.
In addition to highlighting regulatory intent, the consultation also explores the financial benefits for businesses. Research from DESNZ has cited that supermarkets, offices, and retail parks could save up to £28,000 annually by installing solar carports (based on an 80-space car park).
Increased solar power would also help the UK to deliver its Clean Power 2030 plan, which outlines how the UK will meet 95% of its annual electricity demand with clean energy by 2030. Launched by the UK government at the tail end of 2024, the plan sets an ambitious goal of decarbonising electricity across the grid.
