M Group has acquired Kettering-based high voltage connections specialist HVSS, adding more than 120 staff, according to Construction News, a deal that matters to developers and network operators because it brings design, connection and maintenance of connections up to 132kV into one contractor as grid connection demand rises. The report said demand for connections is being driven by investment in renewable energy, electric vehicles and data centres, and the reports reviewed did not state the price.

M Group is a UK infrastructure services company that reported turnover of £3.08 billion in its latest annual accounts, according to Construction News, and is owned by CVC Capital Partners, a private equity firm that acquired it in October 2024.

HVSS is an independent connection provider founded in 2010 that designs and delivers electricity connections up to 132kV from offices in Kettering, Leeds and Cardiff, with turnover that rose 31% to £48 million in the year to March 2025, according to Construction Enquirer.

M Group said in its statement that the deal adds high-voltage engineering, multi-utility connections and private network expertise to its Energy Infrastructure business and supports an end-to-end offer from design through energisation, upgrades and maintenance.

Andrew Findlay, chief executive of M Group, said in the company’s statement: “This acquisition is great news for M Group, HVSS, and our clients. It materially strengthens our capabilities in the high-voltage connections market at a critical time in the UK’s energy transition, and means we can offer our clients a broader range of services to meet their strategic needs.” Richard Parkes, managing director of HVSS, said in the same statement: “Joining M Group will be transformational for HVSS.”

Construction News reported that M Group invested £265.4 million in acquisitions in the year to 31 March 2026, as part of an acquisition-led strategy.

Construction News also reported in December 2025 that M Group had substantial undrawn borrowing facilities to support further acquisitions.

According to edie, an ADE Demand report found that factories are abandoning grid connection plans in favour of gas because of slow connection timelines.

For the sector, a consolidator adding independent connection capacity shows contractors building end-to-end offers around connection demand, where timelines are already a constraint for industrial users.
