Legionnaires Testing


At Island Gas, we are a specialist team of trusted Legionella risk assessment experts based in Hayling Island, assisting commercial and residential property owners across the South Coast with their Health and Safety Executive (HSE) and Approved Code of Practice (ACOP) Legionnaires risk assessments. 

At Island Gas, we conduct competent legionnaires' assessments on heating and water systems across the South Coast, assisting a diverse range of residential and commercial customers from Portsmouth, Chichester and The Witterings. 

Our risk assessments are an option for all domestic property owners and businesses within the commercial sector, including:


  • Hotels 
  • Swimming pools 
  • Leisure centres 
  • Residential homes 
  • Assisted living 
  • Landlords 
  • Hospitals 

And so much more. 

With the potential fatality of Legionnaires' disease and the severe health conditions that can arise from Legionella bacteria, risk assessments are a HSE legal requirement under the Health and Safety at Work Act, for every business within the UK (regardless of its size). Our Legionnaires assessments are essential in eliminating the risk of legionella bacteria, along with other potential issues within the water systems. This process plays an imperative role in keeping employees, staff and visitors on the premises as safe as possible. 

At Island Gas, we advise that all commercial customers undergo a Legionnaires risk assessment every 2 years to ensure their heating and water systems are working optimally, alongside preventing the chance of bacteria build-up throughout the systems that could lead to potential health hazards and more. 

Our Legionnaires risk assessments are comprised of a variety of inspections and tests carried out on the heating and water storage systems throughout the property, including:


  • Documented system overview 
  • Testing of hot and cold water at key points 
  • Survey of water tank 
  • Flow and stagnation testing
  • Aerosol formation hazard inspections
  • Supply of digital thermometers and records 

As a specialist team of commercial heating and gas engineers at Island Gas, we are not only skilled in the legionella assessment process but are also fully equipped with top-of-the-range testing tools and equipment. This ensures all of our risk assessments are conducted meticulously, allowing us to achieve accurate results with every assessment we carry out. This means, once we have deemed all aspects safe and compliant with current regulations, you can settle knowing that your water systems will be HSE and ACOP approved.
