The CENWAT module is the most essential add-on for any domestic gas engineer, covering the installation, exchange, service, and repair of central heating boilers and water heaters. As most residential gas work revolves around heating systems, holding your CENWAT ticket is vital for maximizing your workload and providing a complete service to your customers.
Gas Cookers & Hobs - CKR1
The CKR1 Domestic Gas Cooking Appliances qualification is an essential specialist ticket for gas engineers looking to expand their service offering. This assessment allows you to legally install, service, and safety-check domestic gas cookers, hobs, and range cookers. It completes the "whole house" skill set that customers expect from a professional Gas Safe registered engineer.
Gas Fires & Wall Heaters - HTR1
The HTR1 Domestic Gas Fires and Wall Heaters qualification is a vital specialist assessment for engineers looking to offer a complete home heating service. This module provides the training and assessment required to legally install, service, and safety-check a wide range of domestic gas fires and wall-mounted heaters. It’s an essential step for engineers wanting to operate independently and broaden their professional capabilities.
Gas Meters - MET1
The MET1 Domestic Gas Meters qualification is the final piece of the puzzle for many domestic gas engineers. This specialist assessment certifies you to safely install, exchange, commission, and disconnect domestic gas meters (up to 6m³/h). Whether you are working on new installations or performing essential maintenance, MET1 is a key requirement for any engineer wanting to provide a comprehensive service to their clients.

What is the difference between an ACS initial assessment and reassessment?
An ACS initial assessment is generally for candidates who are undertaking an assessment for the first time in a particular area or who do not hold a current relevant certificate.
An ACS reassessment is for an operative who already holds or has previously held the relevant qualification and needs to renew or reassess their competence.
The entry requirements for reassessment can vary depending on the qualification. For example, the CCN1 Re-assessment course is intended for candidates who have previously held a CCN1 certificate that has expired within the specified timeframe. Candidates attending a reassessment should check the individual course requirements and bring their most recent certificate where required.
If you are unsure whether you need an initial assessment or reassessment, our team can help you identify the appropriate course based on your previous qualifications and certification history.
Can I become a gas engineer with no previous experience?
Yes. There are training routes available for people who are new to the gas industry, although becoming competent to undertake gas work requires more than completing a short course or single assessment.
For new entrants, the Level 3 Gas Engineering Managed Learning Programme provides a structured route combining centre-based training with supervised workplace experience. The programme covers areas including gas safety legislation, installation principles, tightness testing and purging, pipework installation, domestic gas appliances, fault-finding and diagnostics, practical training and preparation for final assessments.
Learners must also gain supervised workplace experience with a suitably competent Gas Safe registered engineer or approved workplace mentor. This allows them to build the required portfolio of evidence through real-life gas work before progressing to the final assessment stage.
