Step 2 - Portfolio Building

Supervised by a gas safe registered engineer*, you will undertake on-site work experience to build up a portfolio.

A legal requirement for your training, stage three is also essential to your development. You will also complete your summative assessment. This includes three written assessments, one practical assessment and a portfolio assessment.

*We can place you with a local gas engineer to work with if necessary.

Step 3 - ACS Assessment

Upon completion of your portfolio, you will return to the training centre for your final ACS exams.

This consists of your ACS Initial Assessment which will test you on gas safety and the full domestic suite of appliances.

ACS qualifications are essential for any gas engineer as they enable you to apply to the gas safe register.

As a gas and heating engineer, you can be your own boss. Setting your working hours, choosing where and when you work and most importantly, setting your own rate, being a gas engineer allows you flexibility and freedom in your career. The average salary of a gas engineer in the UK is a substantial £32,000, but it can rise to £60,000 depending on location and services you offer.

Working as a gas and heating engineer, you will meet new people, travel, and no two days will ever be the same. Customers who receive good service will remain loyal and recommend you to others, meaning your customer base will grow – along with your salary.

Independently reviewed and trusted

Up to 31st December 2020 Regulated qualifications and UKAS Accredited certificates of competence issued in the UK were widely recognised by other EU member states. However since the UK’s withdrawal from the EU, individual member states that previously recognised a UK qualification may now no longer do so. Learners undertaking qualifications on the basis that it is recognised by an EU member state should in the first instance make enquiries with the relevant bodies in that Country to confirm its recognition status.
