2,791 energy-saving measures were installed in the capital as part of the Great British Insulation Scheme, according to new Ofgem data analysed by PE.
The measures helped 2,320 households from May 2023 to November 2024.
The £1 billion government scheme looks to help people insulate their homes to make them more energy efficient and help people save money on their bills.
Josh Edwards, from PE, who analysed the data, said:
“Making homes more energy efficient is one of the best ways to combat rising energy costs while also reducing environmental impact. Simple upgrades such as improved insulation, draught-proofing, and installing energy-efficient heating systems can make a real difference in keeping homes warmer for less.
“For households looking to cut energy bills, small changes like using energy-saving light bulbs, sealing gaps around doors and windows, and adjusting heating settings can all contribute to long-term savings. Even low-cost measures can have a big impact when combined.
“The same principles apply to businesses and commercial properties, where energy efficiency upgrades can significantly cut overheads. From better insulation to smart heating controls, investing in sustainability is not just about reducing costs—it’s about future-proofing buildings, enhancing workplace comfort, and demonstrating a commitment to environmental responsibility.”
