UK Boosts Clean Energy and Home Retrofits with Major Policy Moves

Welcome to Net Zero News, your daily briefing on the UK’s transition to a low‑carbon future.

The UK government and key sector players have recently unveiled a series of climate‑action and net‑zero policy developments, marking significant strides across energy infrastructure, clean transport, and home decarbonisation.

Ofgem has introduced a groundbreaking “cap and floor” support scheme to unlock long‑duration electricity storage (LDES), encompassing technologies like pumped hydro, flow batteries, and liquid air storage. This initiative is designed to capture surplus renewable energy, stabilise the grid, and underpin the UK’s journey to net zero by supporting a projected 20 GW of LDES by 2050 potentially saving the system £24 billion and reducing dependence on gas. The scheme also offers long‑term revenue security to investors while protecting consumers from excessive profits.

Meanwhile, the government has revealed its Clean Energy Plan with a focus on delivering a “super‑power” vision. It includes a commitment to boost grid investment by £10 billion annually between 2025 and 2030, along with reforms to the infrastructure connection process and accelerated planning, aiming to deliver stable power and drive down bills. A key component is the launch of a Clean Energy Workforce Strategy to scale up the low‑carbon workforce, over 450,000 strong today.

In the built environment, the Warm Homes Plan originally set for rollout in late 2025 is now slated for publication in January 2026. While funding for social landlords has already been confirmed (up to £1.29 billion), alongside £500 million earmarked for local authority retrofit grants, key details such as the future of the £7,500 heat pump boiler upgrade grant and post‑ECO (Energy Company Obligation) funding mechanisms remain unclear. The ECO scheme will end in March 2026, and households may see a small saving in energy bills, though its replacement is pending.

Additional retrofit announcements include Riverside Housing Association’s three‑year, £72 million programme to upgrade over 3,000 homes across Northern England and London. Backed by £36 million from Wave 3 of the Warm Homes: Social Housing Fund and matched in-house, the work will deliver energy efficiency improvements such as wall insulation, solar panels, and upgrades to Energy Performance Certificate Band C. This aims to lower bills, cut emissions, and support local jobs and community engagement.

What this means:
• The introduction of the LDES cap and floor scheme removes investment barriers and promises long‑term grid flexibility critical for maximising renewable energy and reaching net zero on schedule.
• The Clean Energy Plan’s ambitious grid funding and workforce strategy addresses systemic bottlenecks while fostering a skilled green jobs pipeline across the UK.
• Delaying publication of the Warm Homes Plan to January 2026 pauses clarity for homeowners and retrofit providers; grant terms and long‑term programmes like ECO need confirmation.
• The Riverside retrofit rollout exemplifies how targeted investment delivers real benefits: warmer homes, reduced carbon, and economic uplift in local communities.
