Major Push in UK Home Retrofit as West Midlands Launches £167m Fund

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

The West Midlands Combined Authority, under the leadership of Mayor Richard Parker, has unveiled a landmark £167 million energy efficiency fund aimed at upgrading up to 10,000 of the region’s oldest and coldest homes. This initiative includes measures such as insulation, replacement doors and windows, solar panels and green heating systems. The funding is expected to unlock around £80 million in additional investment from councils and housing providers, extending the programme’s impact across private and social housing stock. It also marks the largest home energy efficiency scheme WMCA has launched since its inception in 2016.

Complementing this residential endeavour, the Combined Authority will invest £36 million to retrofit public sector buildings, including schools, NHS facilities, colleges and emergency service offices, reinforcing the region’s commitment to hitting its net‑zero by 2041 target. The fund was launched in Wednesbury’s Friar Park estate, where retrofit works are already underway on homes constructed in the 1920s and 1930s.

This funding push is supported by investment in skills and capacity‑building. Nearly 1,000 individuals have completed retrofit training courses funded by WMCA since May 2024, equipping local professionals with the know‑how to install green technologies and insulation.

Meanwhile, at the national level, the government has allocated an additional £1.25 billion to the Social Housing Decarbonisation Fund (SHDF), aimed at retrofitting up to 140,000 social homes between 2025 and 2028. As part of this package, a £500 million local authority retrofit scheme is earmarked to support up to 60,000 low‑income and cold homes, both on and off the gas grid, with insulation and other energy efficiency measures. The scheme is planned to open in 2025.

These proactive measures reflect growing momentum in the retrofit sector: housing associations such as Riverside are advancing large‑scale projects backed by Wave 3 of the Warm Homes: Social Housing Fund. Riverside’s £72 million initiative will upgrade 3,064 homes across Liverpool, Halton, Carlisle, Middleton and Enfield, supported by £36 million from government matched by the association.

Consortium models are also gaining traction. Places for People is heading the Thriving Communities Consortium, including seven social landlords pooling nearly £31 million from WH:SHF Wave 3 and matching funding to install heat pumps, solar panels, double glazing and other retrofit measures across thousands of homes. The partnership expects to complete works by winter 2028, while saving more than £2.1 million in project costs and over £250,000 in training expenses, and driving job creation through apprenticeships and social value initiatives.

On the delivery side, the LHC’s N9 Retrofit and Decarbonisation framework has confirmed 126 contractors for a £660 million programme covering consultancy, insulation, low‑carbon heating, building performance, electrical services including EV charging, and solar PV installations. The framework emphasises social value and supports upskilling through retrofit skills academies, masterclasses and best practice groups, helping suppliers meet PAS 2030 and PAS 2035 standards.

Furthermore, one of the UK’s largest building reuse projects has been announced in the City of London. Mace, appointed by a major asset manager, will deliver the retrofit of 65 Gresham Street, retaining more than 70 percent of the building’s existing structure, recycling or reusing 95 percent of materials, and achieving a 66 percent reduction in whole‑life carbon. The building will be fossil fuel‑free in operation and construction, featuring air‑source heat pumps for heating, cooling and hot water, and delivering more than 100 percent biodiversity net gain through greening initiatives.

What this means:
This series of landmark initiatives illustrates the growing alignment of policy, finance and delivery in accelerating retrofit across the built environment in the UK. Regional schemes like WMCA’s fund are unlocking local impact while generating additional investment and skills training. At the same time, national funding through SHDF and other programmes is helping to scale retrofit across social housing stock. Consortium approaches and structured frameworks are crowding in efficiencies, social value and compliance with emerging standards. Even commercial reuse projects are adopting carbon‑centric design and materials‑conservation principles. Together, these developments signal a maturing retrofit ecosystem geared toward systemic decarbonisation and long‑term carbon savings.
