Water Hygiene Services

Our water hygiene services enable expert water management, water quality, water hygiene risk assessment, and L8 legionella compliance.

We are experts in ACoP L8, HSG Parts 1,2 and 3 compliance, water testing, water management, legionella control and treatment, cleanliness and maintaining both water quality and microbiological control in water distribution systems.

Good water hygiene is about preserving the health of water systems including drinking water supplies, potable water, process water, air handling units, swimming pools, spa pools, domestic water systems supplying showers and any application where an aerosol spray can be generated.

We provide a full suite of water hygiene services to monitor and maintain water hygiene in food and beverage processing, higher education, healthcare, and industrial & manufacturing environments.


  • If water is stored or re-circulated as part of your system.
  • If water temperature is between 20-45℃ in all or part of your system.
  • If there are deposits (eg rust, sludge, scale, organic matter) present which could encourage bacteria growth.
  • If water droplets are produced on site (via wash / spray / showers / cooling towers etc).
  • If you pre-treat water drawn from bore-holes or if there are potential sources of contaminated water on-site.
  • If primary or secondary disinfection is required to protect water safety and improve water quality for potable and or process water.

Water hygiene requires:

  • Risk assessments to evaluate whether suitable control measures are in place.
  • Microbiological analysis of water and UKAS-approved water testing to monitor whether harmful organisms are present.
  • Water management, water system cleaning and chlorination and control of legionella and microbiology of pipes and the water distribution system.

Water Hygiene Services case studies


We provide a full range of water hygiene services to site and contract managers, estate managers, HAV and maintenance engineers and Duty Holders enabling them to maintain and demonstrate exacting compliance and wellbeing for employees, visitors and the wider community – without compromise.

Water hygiene risk assessment >

Formal (independent) assessment of on-site assets, water storage system condition, system hygiene, temperature checks, Legionella control measures, photographic register of assets, schematic to show the inter-relationship of equipment and risks, recommended actions, ACoP L8 risks and how to fully comply and remain safe.

Legionella risk assessment reviews >

Required if there are changes to the water system or if Legionella is detected. As for a Legionella Risk Review or Update for peace of mind.

Monitoring services >

Outsourced (human) and / or tech-enabled remote monitoring of temperatures, air quality, dust etc linked to risk assessments and recommended risk control measures. We can bundle water, air and other critical asset monitoring which reduces labour time, travel time, carbon footprint and has significant ROI.

Water tank cleaning, system flushing and disinfection

Keeping cold water storage tanks, pipes, filters, shower heads, sentinels and spray sources scale and bacteria-free. Our teams perform cleans to ensure you comply with HSG274, ACoP L8 and COSHH regulations.

Microbiological analysis of water >

Includes Legionella testing, Total Viable Count (TVC) and potable water testing and extensive tailored testing for your site.

Water heater plant inspections and installations >

We inspect hot water plant and domestic hot water services to guard against sediment and bacteria growth, potential for contamination and Legionella risk.

Water Heater Plant Inspections >

We regularly inspect hot water plant and domestic hot water services to guard against sediment and bacteria growth, potential for contamination and Legionella risk.

Thermostatic Mixing Valve (TMV) testing and services >

TMV’s are utilised to control scalding risks to vulnerable people. HSG274(2) requires TMV’s to be serviced and tested to ensure they are clean and in good working order.

Managed water treatment programmes >

With routine monitoring of biocide levels and microbiological control

Chemical supply >

Liquid and solid chemicals including oxidising and non-oxidising biocides and biofilm control measures.

Chlorine dioxide (ClO2) generation and production >

Including modern catalytic technology with produces a dilute concentration on demand without hazardous chemical mixing or storage.

Other forms of primary and secondary disinfection of water >

From traditional sodium hypochlorite, electrolysis of brine, ozonation, Ultraviolet Light (UV) and our patented Ultralox40®, an efficacious, fast-acting biocide.

Water hygiene and Legionella awareness training >

Multiple courses (technical, non-technical, starter, refresher) courses are available for site operators and management all over the UK.
