Course Benefits

Membership of the Gas Safe Register is a legal requirement for any installer wishing to carry out gas work in the United Kingdom, Isle of Man and Guernsey. To register as a domestic gas installer, you must hold Core Domestic Gas Safety (CCN1) plus certification for the appliances you intend to work on.

Entry Requirements

The CCN1 re-assessment course is for gas installers who need to renew their domestic ACS qualifications. In order to undertake re-assessment, operatives must complete the course no more than 12 months after the expiry date of their existing qualifications. The CCN1 re-assessment can be completed up to six months before this expiry date. Installers may only undertake gas appliance re-assessment in modules which they have previously been certificated under the ACS scheme.


Both the trainers and assessors are excellent. A very clean and tidy centre.
