What NG Bailey does

NG Bailey is a family-owned and independently operated UK engineering and services company founded in 1921, headquartered in Leeds, with operations across 25+ UK locations and 3,600+ employees following the April 2026 acquisition of Engineering Solutions Group. The company delivers integrated mechanical, electrical, and power engineering services across six core divisions: Engineering (M&E design, offsite manufacture, and installation), Power Engineering (operating as the Freedom brand, delivering NERS-accredited LV/HV/EHV infrastructure for critical national infrastructure), Digital Technology (IT infrastructure, networks, cabling, cloud, and 5G enterprise services via a Nokia partnership), Low Carbon (decarbonisation solutions including heat pumps, solar PV, battery storage, LED, and EV charging), Offsite Manufacture (OSM, modular pre-engineered solutions from Yorkshire facilities), and Technical Facilities Services (planned and reactive integrated building maintenance). Customers span defence (UK Ministry of Defence), healthcare (NHS Trusts), aviation (Manchester Airport), advanced manufacturing (Tata Group battery gigafactories, Jaguar Land Rover), energy (EDF on Hinkley Point C and Sizewell C, BP Pulse), commercial real estate (British Land, Tesco), financial services (HSBC, Nationwide), telecommunications (Openreach), and data center operators.

The technology stack is engineering-led rather than software-led, with proprietary or differentiated assets in OSM offsite manufacturing (cost efficiency), POC-MAST power infrastructure technology (programme risk and cost reduction on network upgrades), and a NERS-accredited ICP capability for direct electrical connections. The Freedom business operates as a regulated ICP, providing design advisory, DNO-regulated network services, and end-to-end EHV infrastructure. Digital services include data cabling, critical infrastructure, defence infrastructure IT, and network services. Low Carbon offerings combine strategic advisory with delivery capability. The portfolio is delivered by a specialised engineering workforce across mechanical, electrical, power, and digital disciplines, supported by ISO 9001/14001/45001 certifications and Princess Royal Training Award recognition (2025).

Revenue is generated through custom-quoted, multi-year project contracts with enterprise and public-sector clients, combining professional services (engineering design and installation), product/module sales (OSM), and managed services (technical facilities maintenance). The company acts variously as principal contractor or specialist subcontractor on major UK infrastructure projects, with partners including Mace on Manchester Airport T2. GTM is direct enterprise field sales targeting strategic accounts, complemented by industry events, PR, content/thought-leadership, and organic social. Key disclosed financial metrics are FY2026 turnover of £707m (up from £662m in FY2025), underlying operating profit of £21.2m (up from £15m), and an order book of £1.7bn. The Journey to 2030 growth strategy emphasises low-carbon capability, water infrastructure expansion via ESG, and operational margin improvement. Ownership remains with the Bailey family, with no private equity or institutional involvement disclosed.
