The Plumbing Licence enables individuals to legally work as plumbers. The licence comes in the form of a Blue CSCS Card or Skilled Worker CSCS Card. CSCS cards are issued as part of the Construction Skills Certification Scheme and are valid for 5 years. The scheme aims to maintain safety on construction sites and in the workplace generally. To acquire a CSCS card, you must complete health and safety assessments. A career in plumbing can be fulfilling and puts you in control of your working life.
