UK Renewable Energy Approvals Soar to Record High in 2025

Record-Breaking Year for Renewable Energy

Great Britain has witnessed an unprecedented surge in renewable energy project approvals throughout 2025, marking a significant milestone in the nation's transition to clean power. Data from Cornwall Insight reveals that the energy capacity of new battery, wind, and solar projects given the green light climbed to a remarkable 45GW this year. This figure represents a substantial 96% increase compared to approvals in 2024.

The momentum was particularly evident in the second quarter of 2025, when the UK government approved 16.1 GW of new renewable energy capacity, setting a new quarterly record. This encompassed 323 projects, nearly tripling the number cleared during the same period last year, and signifying a 195% increase year-on-year.

Key Drivers of Growth

The record approvals were largely propelled by substantial growth across several key renewable technologies:

• Battery Storage: Applications for new battery storage projects almost doubled, reaching 28.6GW in 2025, up from 14.9GW in 2024.
• Offshore Wind: Planning approvals for offshore wind developments saw a more than sevenfold increase, jumping to 9.9GW from 1.3GW last year.
• Solar PV: In the 12 months leading up to the end of Q3 2025, 710 solar PV projects received approval, contributing a record 5,448 MW of solar capacity. Solar generation itself repeatedly broke records in the first half of 2025, peaking at over 14 GW on July 8. Rooftop solar PV installations also hit a record 206,682 in November 2025.

Over the past five years, planning approvals for battery, wind, and solar power have collectively risen by more than 400%, underscoring a sustained commitment to renewable energy development.

Government Ambition and Future Outlook

Energy Secretary Ed Miliband commented on the achievement, stating that the government is 'keeping its promise to take back control of Britain's energy with clean homegrown power.' The Labour government has set an ambitious target to make 95% of Britain's power carbon-free by 2030. Furthermore, the government's Solar Taskforce aims to deploy 70 gigawatts of solar by 2035. The Department for Energy Security and Net Zero (DESNZ) has indicated that the UK is on track for unprecedented levels of renewable energy production in 2025.

In Q3 2025, renewables accounted for 54.7% of electricity generation, marking the second-highest percentage share on record. In the 12 months to January 2025, 42.3% of the UK's energy production originated from renewable sources.

Challenges Ahead

Despite the positive trajectory, challenges remain. Industry experts, including Robin Clarke, a senior analyst at Cornwall Insight, note that many approved projects could still face delays in becoming operational. Significant investment in grid reinforcement and upgrades is crucial, as the current infrastructure was not designed for such high volumes of intermittent generation and storage. Planning reforms are currently progressing through parliament in an effort to streamline approval processes and address these bottlenecks.
