SF6 Training and Certification

Since the Fluorinated Greenhouse Gas Regulations were revised in 2014, if you carry out any activities that directly involve the recovery or handling of SF6 from high voltage (HV) switchgear, then you need to have passed a theoretical and practical examination in SF6 handling and hold a certificate of competence issued by an accredited certification body.

EA Technology is DEFRA accredited to offer this training and assessment which includes theory and practical assessments to confirm your knowledge, understanding and compliance with UK regulations and procedures. These assessments lead to certification of competence for successful candidates.

*EU 517/2014, 2015/2065, 2015/2066 and 2015/2068 have been retained in UK legislation, but have been amended due to the UK leaving the EU and now only apply in the UK.
