M Group Buys £48m High Voltage Specialist HVSS in UK Power Push

M Group has acquired HVSS, a high voltage connections specialist with a £48m turnover, in a deal that tightens its hold on the UK power infrastructure market.

The Kettering-based firm brings more than 120 staff and proven expertise in designing and delivering electricity connections up to 132kV. The purchase feeds directly into M Group's Energy Infrastructure business, which is riding a wave of demand for new and upgraded grid connections as investment pours into renewables, electric vehicles and data centres.

HVSS did not arrive as a fixer-upper. The company lifted turnover by 31% to £48m in the year to March 2025. That's not a distressed asset; that's a business with momentum, and M Group has bought the momentum along with the vans.

Who is HVSS?

Founded in 2010, the independent connection provider works from Kettering, Leeds and Cardiff. Its project list spans:

• High voltage and multi-utility infrastructure
• Industrial and commercial developments
• Residential schemes
• Electric vehicle charging projects
• Health sector facilities

That spread matters. Grid connection demand is no longer a single-sector story — it cuts across housing, industry, healthcare and transport electrification at once.

What does the deal change for M Group?

M Group said the acquisition lets it offer a broader service running from initial design through to energisation, upgrades and ongoing maintenance. In plain terms: one contract instead of several, and a client relationship that doesn't end at switch-on.

Andrew Findlay, chief executive of M Group, called the timing deliberate. "This acquisition is great news for M Group, HVSS, and our clients," he said. "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."

Note the phrasing. "A critical time in the UK's energy transition" is executive-speak for: the grid connection queue is long, clients are impatient, and whoever holds in-house high voltage capability wins the work.

What does HVSS get out of it?

Scale, mostly. Richard Parkes, managing director of HVSS, was blunt about the asymmetry of benefits: "Joining M Group will be transformational for HVSS. M Group's scale, breadth and client relationships will help accelerate our growth, secure larger and more complex projects, and provide our people with greater career opportunities."

"Transformational" is a word smaller firms rarely use about being acquired unless they mean it. Larger, more complex projects are precisely where independent connection providers hit capacity ceilings — and where a parent company's balance sheet removes the ceiling.

The deal signals where the UK infrastructure market is heading. As renewables, EV charging networks and data centres multiply, the bottleneck is shifting from generation to connection, and firms that own that link — design through energisation through maintenance — are consolidating their position. Expect more acquisitions of this shape, at these turnover levels, before the year is out.
