Is this the right course for me?

This is an ideal course for Service leavers seeking to learn a trade, and work in multiple locations across several appliances, with the opportunity to further develop into other areas of gas engineering. You must be able to work independently or as part of a small team, completing tasks to the highest quality within time constraints.

Although an engineering background is not required, attendees should have some technical skills and be willing to commence a new career as a Newly Qualified Gas Engineer, gaining experience in the role once qualified.There is also the option to consider Dual Fuel smart metering which will normally require some additional ‘on the job’ training once you have completed your assessment with MKC . Assessment would be at a local centre to you. 

This is an intensive and challenging course. Attendees must be willing to complete work outside of normal training hours, as well as undertaking the Level 3 Diploma in Gas Utilisation, containing 26 short assignments, with further  controlled assessments taking place in Phase 2. LCL Awards have mapped the MLP across to the Diploma, reducing the required assignments from 43 to 26.

All attendees will be enrolled on a Managed Learning Programme and attendees should be prepared to complete a block period of 6-8 week work attachment full time.

Please ensure you read the full course content and course eligibility requirements below.
For those settling in Scotland,  the ACS training and qualifications are valid, however Gas Engineers are required to adhere to the Scottish Building Regulations when installing appliances. This is highlighted during Phase 1 of the course. 


  • ACS CCN1 Core Domestic Gas Safety plus up to 3 appliances: CENWAT1 (Central Heating and water heating appliances), CKR1 (Cooking Appliances) and MET1 (Meters)
  • BPEC Water Regulations Certificate
  • LCL Awards L3 Diploma in Gas Utilisation


This course requires no prior experience of Gas and is suitable for new entrants to the industry; however, the duration of work attachment will be determined by the level of any prior relevant knowledge, and is expected to be 6-8 weeks full time.

All Service leavers planning to attend this course must have a minimum level 2 functional skills in numeracy and literacy, or equivalent. It is essential that our booking office or the staff at Chatham are made aware of any medical or learning difficulties which may affect your training, at the time of booking. For example, students with written evidence of dyslexia may require additional hours (or days) to complete Phase 2 assessments, and so this must be brought to our attention at the time of booking.

Course attendees will be required to complete the full 25 days of Phase 1 training in order to gain the necessary safety and appliance training required for the workplace. It is a condition of the course that Phase 1 training is fully completed before attending a work attachment, and returning at a later date to complete course assessments.

It is expected that a full driving licence will be required to perform in the role of a Gas Engineer as work will be carried out at homes and businesses, with multiple visits in a day. This will also apply during work attachments.
Attendees should also be physically mobile and able to reach up and also work at low levels.

Attendees should expect that a CRB background check will be carried out for any work attachment or future employment as the role will require you to enter people's homes.

If you have any previous convictions which may affect a work attachment, please discuss this with your Career Consultant or our booking office.

Phase 1 Gas Training
Attendees will be enrolled on a Managed Learning Programme which will involve completion of some forms and an initial discussion with staff at Chatham to ensure you understand the work requirements and intense nature of this course. Any issues or special considerations/learning needs must be disclosed at this stage.

The course will initially consist of 5 weeks of theory and practical training at the training facility at RSME Chatham. 

There will be a significant amount of pre course reading to undertake. This will cover topics such as basic plumbing, health and safety etc. Students will be tested on this pre course reading once the training commences at Chatham.

Phase 1 Content
Phase 1 covers the syllabus of the Level 3 Diploma in Gas Utilisation, and a full outline can be found here: https://lclawards.co.uk/qualifications/rqf/lcl-awards-level-3-diploma-in-gas-utilisation-core-skills-and-knowledge/

Level 3 Diploma in Gas Utilisation - this is started as part of your 25 days learning in Chatham, at which point you will be given a student learning pack that is to be used for the duration of the qualification.  There are online tutorials and further teaching and support  throughout including when you return for your ACS Assessment.  Detailed feedback will be given at all points through your learning journey to assist you in achieving this qualification.  You will have ten weeks from the last day you are in Centre to complete your assessments, during which time you will have continued access to tutorials, support and professional discussions.

Work Attachment:
Following Phase 1 training the attendee must complete a 6–8 week work attachment with a domestic gas company, in order to compile the necessary Portfolio of Evidence required to gain the qualification. This portfolio must be submitted to the course trainers at Chatham in advance of attending Phase 2.
Staff at RSME Chatham will book attendees on the next Phase 2 after completion of their work attachment and Portfolio.

The duration of the placement will depend upon the type of experience required to complete the portfolio and assessments. The placement should be organised by the attendee particularly if they have specific requirements on location etc. CTP can assist where the individual has been unable to source a placement, however there are no guarantees on the location. CTP are working with Employers to post more work attachment opportunities on our Rightjob website. Please log in to Rightjob in the first instance to search for Gas placement opportunities. 

The Portfolio will require completion of 25 tasks, as listed in the table below. These are a mix of installation and servicing and repair. Tightness tests and installation of pipework also fall within the other installation requirements.. We foresee that the work attachment period may in many cases take longer to gain the full range of experience. In most cases this will be a minimum of 6-8 weeks but potentially more time may be required depending on workload and available jobs.  Attendees will no longer be required to complete 5 meter installations but meters will still be covered on the course and awarded as part of the overall qualification.

When considering your work attachment, you may wish to contact large national Employers, or alternatively smaller local domestic gas businesses who provide a range of services including boilers, heaters, meters etc. We also recommend contacting Housing Associations who may have placement opportunities. The Gas Safe register has a postcode search, enabling you to contact companies in your local area.

Also use mainstream job sites such as Indeed.co.uk or Totaljobs to search for gas companies who are actively recruiting in your area, as they may be willing to provide a placement.

Phase 2 Gas Assessments
After the work placement, attendees will return to the training centre at Chatham for a further 2 weeks to complete the examination and assessment phase of training. This will include written testing as well as verbal and practical assessments.

Please note, this course should be completed as soon as possible, but no later than 12 months from the course start date

Career Opportunities

Successful candidates will receive a Gas Card which will detail qualifications obtained and the range of work you may undertake. This will be required by any future Employer. Details will also be uploaded to the National Gas Safe database.

Candidates can then apply to become ‘Gas Safe Registered’ on the national database, in order to become self-employed and carry out private gas installations or repairs. A fee is payable to become Gas Safe Registered (currently £228).

It is recommended that Service leavers seek employment with a gas safe registered company to gain further experience. Most Employers will add engineers to their company gas safe registration.

CTP have some links to local and national companies who are seeking qualified gas engineers.

Login to your CTP RightJob account to view work attachment and employment opportunities for Gas Engineers and please ensure you update your Rightjob profile once you have gained the qualifications.
