About This Course

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.

Our students complete an intensive 2 – 3 Days training course:

  • Our ACS reassessment is a mixture of theory and practical training and assessment. Please note you will only be able to renew any existing qualifications/certificates. If you wish to extend your scope of work by adding any appliances to your certificate, this will incur additional charges.
  • CCN1/CPA1 – Core Domestic Natural Gas Safety and Combustion Analysis V1/18
  • CENWAT1 – Central Heating Boilers and Hot Water Heaters. (Previously CEN & WAT1 ACS were separate modules. They are now combined to form the CENWAT).
  • CKR1 – Domestic Cookers
  • HTR1 – Gas Fires and Wall Heaters
  • MET1 – Meters
  • Unfortunately, we no longer run the Warm Air Module.

Assessment Method

Practical and written test.


Previous ACS certificates (expired within 12 months, or due to expire within the next 6 months), your gas safe registration number and expiry date. Although training is not a pre-requisite to the reassessment, many gas installers feel that refresher training before they undertake their ACS reassessment beneficial. It allows trainers to identify areas in which candidates require further training in. This can be obtained at an additional cost.
