ACS Reassessment

The ACS reassessment and renewal course are for experienced gas engineers (Category 1) who need to renew their existing ACS certificate and qualifications.

For gas engineers to continue to remain on the Gas Safe register and continue to carry out their work legally and safely, it is a requirement to renew their ACS qualifications every five years. Operatives with expired certificates (less than 12 months) or those who are due to expire within the next 6 months will need to complete a reassessment to maintain their certification and gas safe registration.
