Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what progress his Department has made on increasing (a) solar and (b) rooftop solar capacity.

Accelerating solar deployment is a key part of the Government’s clean energy mission. As set out in the recently published Solar Roadmap, solar capacity will need to rise to 45-47GW by 2030.

Since the Government took office, UK solar capacity has increased from 17.8GW (July 2024) to 19.1GW (July 2025).

The Government does not hold precise figures for rooftop solar deployment. However, UK solar capacity from installations smaller than 50kW has risen from 6.3GW (July 2024) to 7.2GW (July 2025).
