What Water Treatment Services (WTS) does

Water Treatment Services (WTS) is the trading brand of EDG Ltd., a UK- and Ireland-based specialist in water treatment and environmental compliance services. Headquartered in Manchester with a multi-site presence (London, Glasgow, Birmingham, Bristol, Kent, Leeds) plus Ireland coverage, the company delivers field engineering, chemistry, and lab analytical services to regulated customers across healthcare, higher education, manufacturing, energy, hospitality, and the public sector, with named clients including the NHS, Imperial College London, ARUP, Johnson Matthey, and the BBC. Its core technology stack is built around dosing programmes for boiler and closed-loop cooling systems, microbial and chemical analysis run through an in-house laboratory, and associated diagnostics including legionella risk assessments and air quality surveys aligned to named standards (BG04, BS 2486, ACOP L8, HSG274).

The company operates a services-led B2B model monetised through recurring service contracts, one-off compliance and survey work, consumable chemical sales (boiler and industrial water system chemicals), training courses, and increasingly through productised self-service tools such as online health assessment instruments. Adjacent service lines — air quality (ductwork hygiene, indoor air quality, local exhaust ventilation, mould remediation), energy efficiency advisory, and water consumption reduction consulting — extend the addressable compliance and ESG budget beyond traditional water treatment.

The business is privately held as a subsidiary of EDG Ltd., with no disclosed funding, M&A, or leadership change events in the supplied data. Customer feedback volume (around 103 reviews at 4.8/5) suggests an operationally scaled, repeat-customer book typical of UK mid-market specialist services. Revenue, headcount growth, and forward indicators of financial performance are not disclosed in the input.
