Background |
This gas safety assessment is designed to test the competence of an operative in determining ambient levels of CO and presence of CO2 in dwellings and identifying the cause of fumes using a portable electronic combustion analyser. This will typically be any engineer who responds to the genuine report of a CO alarm being activated or a report of fumes. The scope of the assessment covers Type A, B & C domestic gas appliances fitted in dwellings and follows the guidance and procedures outlined in BS 7967. Related information has also been issued by HSE in the form of HSE Guidance Notes HSE(EH)40 and HSE(L)56, Gas Safety (Installation & Use) Regulations. It does not cover commercial premises and appliances or the procedures to adopt following an incident reportable under RIDDOR. Where an engineer is required to carry out a formal CO incident investigation on behalf of a gas supplier as part of their obligation under gas safety legislation, the engineer would need to have successfully achieved a relevant qualification in the investigation of CO poisoning and carry out the investigation in accordance with the Institution of Gas Engineers and Managers (IGEM) Industry Standard (IGEM/GL/8) |
Prerequisites |
CCN1/CCLP1 + CPA1) or CCN1/CCLP1 as from 1st April 2012 or valid equivalent NVQ or QCF/RQF qualification + appropriate domestic appliance(s) This is regarded as having an equivalence to a Level 3 qualification. |

Frequently asked questions about this course
Is gas still a popular choice with candidates?
Yes, gas is still a popular choice. The majority of UK homes are still heated by gas, which means even after new gas boilers stop being installed in 2035, there will still be around 23 million homes using a gas boiler. These boilers will need servicing and maintenance for many years to come. Gas also provides the perfect stepping stone into heat pumps and other renewable technologies. LCL Awards' Level 3 heat pump courses are designed for qualified heating engineers (gas or oil).
What qualifications do you need for gas?
To become a gas installer you need to undertake specific qualifications, have relevant experience and join the Gas Safe register. You can achieve Level 3 gas qualifications through an apprenticeship scheme, which usually takes two to three years, combining a work placement with college, or you can complete a Managed Learning Programme (MLP), which covers everything you need to become a gas engineer without going through an apprenticeship. The MLP also includes a portfolio which demonstrates 'real-world' experience, mentored by an existing Gas Safe installer. At the end of a MLP, you would usually complete ACS certification in your chosen areas of gas. All gas installers must complete a core gas safety element (for example CCN1) and then specific modules such as catering, metering or gas fires, for example. Once you have successfully completed ACS assessments, you can join the Gas Safe register - this is a legal requirement for all gas installers. ACS certification must be renewed every 5 years.
What qualifications do I need to be a gas engineer in the UK?
To become a qualified gas engineer in the UK, follow these steps:
- Train - either as an apprentice, where you will complete a Level 3 gas qualification and combine time in college with work with an employer, or through a Managed Learning Programme (MLP). An MLP is an alternative route to becoming a qualified gas engineer usually completed through a private training centre.
- Gain hands-on experience - through your employer as an apprentice, or by completing an on-site portfolio, a key part of the MLP. Any work experience must be supervised by a Gas Safe registered installer.
- Undertake an ACS Training and Assessment: Achieve the relevant Core Gas Safety element (for example CCN1) and elements for specific appliances (e.g., boilers, cookers, fires).
- Register with Gas Safe: This is mandatory for all gas engineers.
