APHC Legionella Risk Assessment & Disinfection Scheme

What is the Legionella Risk Assessment and Disinfection Scheme?

The Legionella Risk Assessment and Disinfection Scheme is a national scheme run by the Association of Plumbing & Heating Contractors (APHC) and the Scottish and Northern Ireland Plumbing Employers’ Federation (SNIPEF) which is a means of demonstrating compliance with the Health and Safety Executive’s Approved Code of Practice for Legionnaires’ disease: The control of Legionella bacteria in water systems (L8).

What does L8 cover?

All hot and cold water systems within all properties that have a commercial use or public access, regardless of cold water storage size fall under the L8 requirement. This includes residential properties that are let by a private or social housing landlord, care homes, schools, offices, sport facilities and changing rooms along with public buildings.

The scope of coverage of L8 was recently amended to bring systems under 350 Litre storage capacity into the legislation. The outcome is that all property types including residential properties that are associated with a business including properties that are let, are required to be subject to assessment of risk for legionella.

What are the benefits?

The Legionella Risk Assessment and Disinfection Scheme allows property owners to meet their obligations by sourcing and working with plumbing professionals who meet the scheme’s criteria.

Membership demonstrates to property owners that they are dealing with a professional and competent plumber, and plumbers receive recognition for their knowledge and understanding of the risks associated with legionella and that they can implement a risk assessment and carry out remedial action where necessary.

Employers, Property Owners and Landlords can learn more from the PHCA Legionella Guide.
