There is a requirement within the gas industry that every gas engineer has to be gas safe registered to legally work with gas. Read our blog about ‘How do I become Gas Safe Registered?’
To be on the register the engineer must hold units of competency. These units are valid for 5 years after that time they must be reassessed to be renewed.
The majority of engineers hold core safety CCN1 and 3 appliances, usually cookers, boilers and fires. They will usually renew the same after 5 years, this would be the Reassessment + 3. They may in the meantime take up additional units i.e. meters MET1, this unit would be reassessed individually and would remain valid for up to 5 years as long as the core CCN1 is still valid.
Some supervisors just hold the core safety CCN1 with no appliances. This only shows competence of the core gas safety and pipe work. This would be reassessment core only.
Reassessment rules: Competency units can be reassessed up to 6 months before expiry with the expiry date being 5 years from the date of expiry (like the car MOT). Engineers who have allowed their competency units to expire for 12 months + or operatives who are entering the gas industry through a managed learning programme will need to take the initial assessment.
