What John Henry Group does
John Henry Group is a UK-based, family-owned infrastructure services provider founded in 1985, delivering civil engineering, fibre network construction, and power infrastructure solutions to enterprise clients across the telecommunications, power, education, and alternative network sectors. The company's core technology stack includes the proprietary Geo-sight data capture platform (a smartphone and cloud system for remote site monitoring and safety reporting) and a patented Narrow Trenching method (developed 2014) that enables fibre-to-the-premises deployment at up to twice the rate of conventional techniques, supported by Trimble MX7 digital survey mapping for sub-millimetre network planning accuracy. John Henry Group also holds NERS accreditation as an Independent Connections Provider, allowing it to deliver turnkey power infrastructure solutions including design, civils, traffic management, cabling and connections for solar, BESS, EV charging, wind farms, data centres and residential developments.
The company operates from its K4 Operations Centre in Longstanton, Cambridgeshire, with regional offices in Essex and Warrington enabling a nationwide 2-hour emergency response footprint. Revenue is generated primarily through B2B project-based contracts and ongoing maintenance frameworks with major PLCs including British Telecom (a client since 1986), Virgin Media, National Grid, and a portfolio of UK universities (Cambridge, Eton, UEA, London Business School), alongside a growing base of Alt-Net providers and power infrastructure customers. The group is structured around several operating brands: the core JHG telecoms and civils business, Avanti (traffic management), Fibrewave (a sister company holding telecoms code powers), and JHG Innovations (the R&D arm for proprietary technology). Growth Capital Partners took a minority stake in 2016 while the Henry family retained majority ownership; pricing is quote-based and not publicly disclosed.
