WGM Engineering

What WGM Engineering does

WGM Engineering is a Scotland-based (Glasgow-headquartered) self-delivery design and build engineering partner supplying sustainable engineering solutions primarily to the UK water sector. Founded in 1986 and acquired by RSK Group in October 2022, the company operates with a team of more than 450 people across offices in Glasgow (Albion Court, Barfillan), Livingston, and Newbridge. Its services span four core lines: planned and responsive maintenance (24/7/365 mechanical and electrical support), off-site engineering (modular fabrication using 3D digital DfMA with CNC fabrication), MEICA projects (£250K to over £20M in the water, wastewater and industrial sectors), and specialist industrial coatings for corrosion and erosion prevention. Additional offerings include renewables (PV solar, hydroelectric) and custom fabrications.

The company's underlying technology platform centres on integrated MEICA delivery under a self-delivery model that combines in-house technical design, BIM-enabled design standardisation, strategically located off-site manufacturing facilities, and on-site construction capability. Notable proprietary elements include off-site modular steel fabrication (walkways, platforms, modular wastewater process units), circular economy asset refurbishment delivering approximately 80% carbon reduction versus replacement, and a partnership-backed PicoStream floating hydropower technology. Headworks International partnership adds MBBR, IFAS, and anaerobic MBBR biological wastewater treatment capabilities.

WGM generates revenue primarily through multi-year framework agreements and project-based contracts with major UK water utilities. Confirmed anchor frameworks include the Scottish Water Enterprise programme (£8 billion over 2027-2033, shared among seven Asset Delivery Partners), the Southern Water Non-Infrastructure Framework (£250 million initial 4-year period with approximately £50 million earmarked for the bWGM joint venture with Binnies), and the United Utilities AMP8 Detailed Design and Build Lot 1 Non-Infrastructure framework (£650-850 million total across all AMP8 partners). Additional revenue streams include an eight-year Scottish Water scraper bridges framework (~£3 million per annum via the ACWA Services partnership) and specialist coatings work for Scottish Gas Network. Customer concentration is high, with frameworks ranging from £500K to £10M per project driving predictable but utility-dependent revenue.
