What HYDROP does

HYDROP E.C.S. LTD is an independent UK consultancy practice, founded in 1991 and headquartered in Sutton Coldfield (West Midlands), that focuses exclusively on Legionellosis (Legionella) and broader water quality risk management. The firm serves enterprise and public-sector clients - notably the NHS, the Defence Infrastructure Organisation, local authorities, universities, facilities management companies and large industrial operators - delivering risk assessments, independent system auditing, Authorising Engineer appointments, bacterial contamination and crisis management, expert witness services, design validation, and scientific research in compliance with ACoP (L8):2013, BS 8580-1:2019 and HTM 04-01.

Underlying the consultancy is a proprietary technology stack anchored by COMPASS, a fully bespoke web-based Electronic Water Quality Risk Management System providing real-time risk assessments, PPM task management, defect logging, and programmed flushing/usage evaluation. This is paired with the proprietary Electronic Data Collection System (EDC), used by Hydrop scientists during risk assessments and comprising thousands of reference points for systematic inspection, and extended to the field via COMPASSMOBILE Tasks and COMPASSMOBILE Flushing apps on iOS and Android. The platform is described as paperless, mobile compatible, and configurable to each client's water asset base.

Revenue is generated across three streams: (i) fee-based professional consultancy, (ii) fee-based training courses (accredited by ILM and City & Guilds, ranging from 45-minute awareness sessions to 3-day Responsible Persons programmes delivered at the Sutton Coldfield HQ, on client sites, or remotely via Microsoft Teams), and (iii) annual subscription access to the Compass software platform. Most training and consultancy pricing is "Price on Application" (POA), reflecting negotiated enterprise contracts rather than standardised list pricing. Distribution is direct (phone, email, website enquiry) with no channel intermediaries, in line with the firm's claimed independence from water treatment and water hygiene product vendors. In 2024/2025, HYDROP E.C.S. joined the Celnor Group, a UK testing, inspection, certification and compliance platform.
