Government published an updated National Planning Policy Framework

The Government published an updated, growth-focused National Planning Policy Framework (NPPF) in December 2024, according to the UK Solar Roadmap¹. The change sits within a wider set of planning and grid reforms intended to accelerate solar and other low carbon generation towards the Clean Power 2030 goal of 45 to 47GW of installed solar capacity, up from over 18GW at present¹.

The Roadmap, published in June 2025, presents the final conclusions of the Solar Taskforce, which was established in May 2023, reconvened by the Government in July 2024 and re-assembled in Autumn 2024¹. It states that the National Policy Statements for energy were designated and came into effect in January 2024, and that the UK, Scottish and Welsh governments jointly commissioned the National Energy System Operator to begin work on the Strategic Spatial Energy Plan in October 2024¹.

On grid connections, Ofgem approved NESO's "first ready, first connected" connections reform proposals on 15 April 2025, and from June 2025 all distribution network operators will be required to submit project information to NESO within the relevant Gate Two window¹. The Roadmap also records that the Government launched its AR7 contract consultation in March 2025, and that a working paper published on 21 May 2025 sought views on introducing a mandatory community benefit fund scheme for low carbon energy infrastructure, including solar, and on facilitating shared ownership of renewable generation infrastructure¹.

The Roadmap sets out separate ambitions for the devolved nations, noting that energy security and net zero policy covers areas devolved to Scotland, Wales and Northern Ireland alongside areas reserved to the UK Government¹. It states that the devolved governments have their own ambitions and supporting policies for renewable technologies¹. The document does not set out household-level planning fees, permitted development limits or application timelines for domestic solar, and these have not been reported in it.

Why it matters for households

Planning policy shapes how quickly generation and network capacity reach the point where a home connects. The Roadmap frames solar as a route to lower bills and greater energy independence, stating that every panel installed helps take back control of energy supply and that rooftop deployment can reduce consumer bills immediately¹. It records that more than 1.5 million homes now have solar installed¹. For a household, the practical link runs through grid connection queues and the planning regime that governs larger projects, both of which affect how much locally generated power is available and how fast the network is reinforced. The Roadmap also commits industry to publish and promote consumer protection guidance in collaboration with MCS, and to publish consumer engagement best practice for developers¹. Rules on how far panels may protrude from a roof, and the separate position in Scotland, are covered in the site's guides to solar panel roof protrusion and solar panels on a flat in Scotland. The wider framework sits under UK home energy regulation and policy, with devolved powers set out for Wales and Scotland, and departmental responsibility covered under DESNZ.

What happens next

The Roadmap states that the Government will publish the Future Homes Standard in Autumn 2025, and that a change recorded in the document will come into force on 31 December 2025¹. It also states that the first audits against a supply chain standard will take place over 2025, with first certifications expected later in 2025 or early 2026, following first site certifications awarded at the end of 2024¹. The Roadmap commits to establishing a joint Government and industry Solar Council to drive progress¹.
