Practical Portfolio: Real-World Experience

A key component of this course is the completion of a practical portfolio. This is a mandatory requirement for your ACS assessments and a vital part of your training. The portfolio must be completed alongside a qualified Gas Safe registered engineer, who can be from your workplace or a personal contact.

The portfolio needs to include:

• Five Boiler Installations
• Five Boiler Services or Repairs

We will provide you with detailed guidance on the documentation and evidence required during your first session at our training centre.
