WJA Certified - Pressure Washing


Pressure washers are commonplace on-site and are ideal if the work doesn’t require industrially high-pressure jetting. They are electric, diesel, petrol or PTO driven and used for anything from vehicle washing, small plant cleaning or general maintenance and cleaning work.

The Water Jetting Association (WJA) upholds regulations and rules for training and certification in water jetting work such as this. As a trade association, they represent contractors, manufacturers, hirers and other organisations that have a professional and commercial interest in all aspects of high-pressure water jetting to promote safety and technical standards for all forms of water jetting, including:

  • Ultra-high-pressure water jetting
  • High-pressure water jetting
  • Pressure washing
  • Drain and sewer cleaning

This Pressure Washing qualification is awarded by the Water Jetting Association and City & Guilds, enabling delegates to demonstrate skill, knowledge, and competence in using a pressure washer at work.
