About the Hot Water Systems and Safety Course Previously known as ‘Unvented G3’

The Hot Water Systems and Safety (HWSS) Course (otherwise known as Unvented G3) is a specialist plumbing qualification accredited by the LCL Awards.

Designed to upskill and develop experienced plumbing and heating professionals, this day-long course provides you with the specialist training and expertise you need to install, service and maintain hot water systems.

The HWSS course has been developed to allow you to work in safe compliance with Approved Document G; the 2016 building regulation relating to sanitation, hot water safety and water efficiency when carrying out work on hot water systems. Training includes requirements for the installation of:

  • G3 Unvented Hot Water Systems

  • systems up to 500 litres capacity
  • systems up to 45kW power input

The HWSS certificate is recognised by Competent Person Schemes (CPS) approved to offer a self-certification scheme under Approved Document G. This means you’ll not only receive training in the installation of hot water systems (including unvented), you’ll also secure the ability to self-certify the installation as part of your service.

If you’re an experienced plumbing or heating professional looking to provide a specialist, sought-after service, this course could help you reach that goal
