What Adler & Allan Group does

Adler & Allan Group is a UK-based environmental risk reduction services provider founded in 1926 and headquartered in Harrogate, operating from 343 UK locations with 1,500+ employees across multiple wholly-owned subsidiary brands (Flotech, Detectronic, Utility Line, Aqua Consultants, Public Sewer Services, QEM, Jet Aire, Glanville Environmental, Thomson Environmental, Atmos Consulting, AMGS Electrical, Oneline Surveys). The company delivers four integrated service lines — Strategy and Consultancy, Assets and Infrastructure, Incident Management, and Energy Transition — combining environmental consulting with field engineering, spill response, hazardous materials handling, no-dig sewer rehabilitation, and asset lifecycle management.

Its technology stack includes the patent-protected TÜV SÜD certified tank lining process (BS EN 13160, 10-year warranty, 40% faster installation), the proprietary LIDoTT sewer level monitoring device, CIPP and Compact Pipe trenchless pipe rehabilitation technologies, and a PFAS treatment solution. Customers include major UK water utilities (Southern Water, Thames Water), the UK Ministry of Defence, and energy infrastructure operators, with services delivered across utilities, energy, defence, transport, manufacturing, construction, facilities management, and insurance verticals.

The business model is enterprise B2B professional services sold via direct field sales on a custom quote basis, generating revenue through emergency response, planned preventive maintenance contracts, environmental compliance consulting, fuel infrastructure projects, and increasingly energy-transition work (EV charging, hydrogen). Growth has been driven by an aggressive M&A roll-up — 10+ acquisitions in three years — under Goldman Sachs private equity ownership, expanding headcount from under 500 to nearly 1,700 and turning the firm into a national integrated environmental services platform.
