Gas & Renewables Training Course | Become a Future Proofed Heating Engineer

The UK has pledged to reduce carbon emissions and strive for net-zero targets by 2050 (Source The Institute for Government). To help achieve this, the heating industry in the UK will need to adapt to new legislation. Heating solutions in domestic properties are likely to combine technologies as we all look to reduce our carbon footprint.

The introduction of renewable energy sources such as heat pumps and Hydrogen to replace natural gas are real possibilities. However, over 20 million domestic properties and many businesses still rely on natural gas as a heat and energy source.

With this in mind, Options Skills has developed a robust Gas & Renewables Training Course. The course is designed to future-proof and meet the needs of modern heating engineers by ensuring that they have the skills and qualifications required to meet the changing needs of our industry. The programme is aimed at new entrants to the industry and those with limited experience and without qualifications.

The Gas & Renewables Training Course by Options Skills is the most comprehensive course for new entrants to this exciting & essential industry. It consists of 4-must follow steps that we will deliver over 12-24 months.

Duration: 8 Weeks

You will begin our Managed Learning Programme (MLP). The MLP is an accredited gas training programme that meets the requirements of The Institution of Gas Engineers and Managers (IGEM).

During the 8-weeks at the centre, you will undergo intensive practical and theory training with Domestic Natural Gas and Domestic Gas Appliances.

In addition to this you will complete your Hot Water Storage Systems (HWSS), including Unvented (G3 of Building Regulations) and Central Heating Design (HSD1). This module consists of: heating and hot water design including knowledge and understanding of “S” & “Y” plan systems, hot water storage, comfort conditions and basic heating and hot water principles, basic system types, heat-loss calculations, system design, system specification and selection including emitters, pipework, boilers and pump sizing, sizing and selection of hot water systems.

Centre led training will take place at one of four centres nationally. We have designed this stage of training to be an in-depth introduction to gas work and installation, preparing you to move on to the next step of your training.
Duration: Minimum 100 Days

Stage three of training is a legal requirement for anyone training to become a gas heating engineer.

You will spend a minimum of 100 days working with a qualified gas engineer. Under their supervision, you will undertake a range of gas work, documenting this to complete a portfolio. Options Skills works with a network of registered gas installers across the country. We can assist with introductions if necessary.

Your portfolio acts as evidence of the work you have undertaken as a trainee and must be of acceptable quality to allow you to progress to the next stage of training. There is a minimum duration of 100 days and a maximum duration of 2-years to complete your portfolio.

Before moving onto stage four, you must pass a summative assessment. A summative assessment includes; three written assessments, one practical assessment and portfolio evaluation. Upon successful completion of your portfolio, you will earn your DNGA 1 – 5 MLP. This certification is evidence to all training providers that you have completed training and portfolio building. You are now ready to book your ACS Initial Assessment.
Duration: 7-10 Days

We will invite you back to the training centre to undertake your ACS Initial Assessment. As the only industry-recognised route, gas engineers must complete the Accredited Certification Scheme to become a member of the Gas Safe Register. Including practical and verbal examinations, you will cover the domestic suite of gas qualifications:
  • Core Gas Safety (CCN1)
  • Central Heating and Boilers (CENWAT)
  • Gas Fires (HTR1)
  • Gas Cookers (CKR1)
Once you have successfully passed your ACS Initial Assessment, you can apply to become a member of the Gas Safe Register. You must be a member before you can legally undertake any gas work. You may apply for Gas Safe Registration in your own right, or you may work for a Gas Safe Registered business as an approved operative. Membership is renewable annually, and fees are payable directly to the Gas Safe Register. ACS Qualifications are not evergreen and must be renewed every five years through an ACS Renewal Course. These courses last up to five days.
Duration: 2 Weeks

Renewables Accreditation includes:
  • Water Regulations (WRAS)
  • Heat & Energy Efficiency EEDHS (Part L of Building Regulations)
  • Low-Temperature Heating Design (LTHWS)
  • Air Source Heat Pump Installation and Maintenance (IMASHPS)
  • Ground Source Heat Pump Installation and Maintenance (IMHPS21)
A vital element of the Gas & Renewables Training Course, heat pumps will form an integral part of the UK's strategy to meet its Net Zero targets. To achieve this, the UK must install 600,000 heat pumps annually to meet the government's target of 19 million heat pumps by 2050. (Source: Heat Pump Association). Training for heat pump installation is only available to people that hold an RQF Level 3 Heating Qualification (i.e. ACS Gas).

During the two-week training and assessment period, you will receive training in low water temperature system design, and installing and maintaining ground source and air source heat pumps. Assessment takes place through design scenarios, work performance activities and written examinations.

Upon completing stage five, you will have gained the following qualifications:
  • Core Gas Safety (CCN1) including CPA1 (Flue Gas Analyser)
  • Central Heating and Boilers (CENWAT)
  • Gas Fires (HTR1)
  • Gas Cookers (CKR1)
  • Heating Design
  • Unvented Hot Design (G3)
  • Part L of Building Regulation (Part L)
  • Water Regulations (WRAS)
  • Low-Temperature Heating Design (LTHWS)
  • Air Source Heat Pump Installation and Maintenance (IMASHPS)
  • Ground Source Heat Pump Installation and Maintenance (IMHPS21)
We believe that this full suite of qualifications will allow qualified heating engineers to respond to current and future domestic heating scenarios. It will also enable them to play a critical role in the future of the country's heating industry, helping us meet our commitment to reducing the carbon footprint.

With the above suite of qualifications, you are eligible to apply for membership of the MCS (Microgeneration Certification Scheme), which is not only a sign of quality and commitment but boasts several benefits for both installers and manufacturers.

Footnote: Natural Gas will continue to play a vital role in heating our homes for a considerable time to come. Whilst there is talk of Hydrogen replacing Natural Gas, this policy is yet to be formalised, and specific training and qualification for Hydrogen does not yet exist. If and when the UK introduces it, it is likely to be in the form of a short conversion course for existing gas engineers. If the UK adopts Hydrogen as policy as part of the UK’s drive towards Net Zero, we will update our training provision at the earliest opportunity.
