CompEx Certified

The CompEx Scheme is the recognised global scheme for the protection of workers anywhere that explosive atmospheres exist. The CompEx Scheme provides competency validation of individuals across a range of disciplines and different hazards to help create a safer workplace.

EUSR national water hygiene card holders

The National Water Hygiene (‘Blue Card’) scheme plays a vital part in ensuring the protection of public health and promoting safe drinking water practices. Originally developed in 2006, this scheme replaced the many different water company specific hygiene training programmes and courses, removing the need for individuals to undergo separate testing, health screening and the carrying of multiple cards.

Construction Skills Certification Scheme

CSCS cards provide proof that individuals working on construction sites have the appropriate training and qualifications for the job they do on site. By ensuring the workforce are appropriately qualified the card plays its part in improving standards and safety on UK construction sites.
