Legionella training keeps water systems safe and protects public health. It helps operatives meet their legal duties under HSE ACoP L8, reduces the risk of outbreaks, and is often required as evidence of competence for SSIP accreditations such as CHAS, SafeContractor and ConstructionLine.

The Operatives course is for installers who physically work on water systems; it includes practical disinfection and requires a valid WRAS certificate to enrol. The Managers course is for people who plan and oversee water systems and focuses on risk assessment, the law and record-keeping, with no practical element and no entry requirements. Both are 1 day, £230 + VAT, and lead to the same LCL Awards certificate.

You’ll learn how to carry out legionella risk assessments and disinfect water systems using industry-approved methods such as bleach, chlorine, silver, hydrogen peroxide and how to keep accurate records that demonstrate compliance.

Yes. A valid WRAS Water Regulations certificate is a requirement for the Operatives course. If you don’t hold one, you can take our Water Regulations course first, or take the Managers course (which has no entry requirements) if you only need to oversee water safety.

No. The Operatives course is aimed at domestic and small commercial water systems and does not cover cooling towers. If you work on those, you should seek specialist training.

You’ll receive the LCL Awards Legionella Prevention & Water Treatment certificate. It’s recognised across the industry and valid for 5 years, after which refresher training is recommended to stay current with legislation.
