Argonaut Heating Limited offers a specialised provision of Legionella Control services for our clients in the London, Essex, Kent, Hertfordshire and surrounding areas.

We offer Legionella Risk Assessments and advice on legislative compliance with the Health and Safety Executive Approved Code of Practice (L8) - The control of legionella bacteria in water systems.

Many outbreaks of Legionnaires’ disease, if not all, are because of lack of training, poor management and incorrectly assessed premises. Legionella Control is required wherever there is water used or stored, irrespective of size and usage.

It is a requirement under the Health and Safety Executive Approved Code of Practice (L8) The control of legionella bacteria in water systems that you have a responsibility to comply with the legal requirements for the control of Legionellosis.

Your duties under the Law

You have a number of duties to control the risks of legionella if:

  • You are an employer
  • You manage a premises with hot/cold water services (e.g. showers) and/or
  • You manage a premises with wet cooling systems (e.g. cooling towers and evaporative condensers)

Employers must consider the risks from legionella

The law requires that you consider the risks from legionella  that may affect your staff or members of the public and take suitable precautions.  As an employer or a person in control of the premises (e.g. a landlord), you must:

  • Have a Risk Assessment carried out by a qualified team who will identify and assess sources of risk;
  • Prepare a scheme, or course of action, for preventing or controlling the risk;
  • Implement and manage the scheme - appointing a person to be managerially responsible, sometimes referred to as the 'responsible person';
  • Keep records and check that what has been done is effective;
  • If appropriate, notify the local authority that you have a cooling tower(s) on site

Our inclusive Legionella Risk Assessment service

Our qualified risk assessor will carry out a detailed assessment of your premises, which will ensure compliance with the Approved Code of Practice ACOP L8.

The building-specific Legionella Risk Assessment report generated will identify any risks as well as any remedial action necessary to meet current standards and legal requirements.

Our fully documented Legionella Risk Assessment includes identification and evaluation of potential sources of risk and includes: 

  • Full asset register outlining the water systems which fall within these guidelines on your site
  • Digital photographs of the assets
  • Outline the current condition of the water systems
  • AutoCAD schematic drawings of your water systems
  • Whether water temperatures are satisfactory for the control of Legionella bacteria
  • Defines any remedial actions required to achieve compliance with the guidelines
  • Schedule for on-going water hygiene monitoring
  • Identification of on-site personnel training requirements

We will quote a fully inclusive price to attend site for the survey, carry out the Legionella Risk Assessment and produce your report.

We can also provide a sample Legionella Risk Assessment report to illustrate the extent of the document you will receive.

We will also provide a quotation for any remedial actions or works required to achieve compliance with the guidelines.

Legionella Service Contract

Argonaut Heating Limited also offers a Legionella Service Contract which includes for us to attend site on a periodic basis and undertake scheduled tasks highlighted in the Legionella Risk Assessment report and offers training for the in-house tasks outlined on the proposal.
