Frequently Asked Questions

How and Why to Join

Who is eligible to join?

All construction professionals with suitable qualifications and experience. The following pre-qualify:

  1. Architects registered with the ARB
  2. Chartered Members of CIAT
  3. Corporate Members and LCCs registered with CIBSE
  4. Existing Approved Certifiers of Design
Why should I join?

As an Approved Certifier of Design, you will:

  1. Retain control of the energy aspects of your projects
  2. Help design teams optimise energy strategies
  3. Provide clients with an enhanced service
  4. Minimise local authority verification time
  5. Benefit from a 10% discount on building warrant fees (if certifying all relevant elements)
  6. Stay updated with technical standards and access technical advice
Why are the Domestic and Non-domestic Schemes separate?

The software differs between domestic and non-domestic calculations. By separating them, professionals don’t need to demonstrate competency in tools they rarely use.

Why is there a distinction between Non-domestic and “Advanced” Non-domestic Approved Certifiers?

Both are registered as Approved Certifiers of Design. The distinction exists because complex non-domestic buildings (schools, hospitals, etc.) require deeper HVAC and systems expertise than simpler non-domestic projects.

Guidance defines when a project is “Advanced.” It’s not only about scale or cost — complexity of services and systems is the key factor.

Can I certify Section 6 – Energy if there are no external fabric changes?

Yes. Section 6 – Energy applies to all building warrant applications, even if works are internal. Certification still gives a 10% fee discount.

How do I join?

Membership has four stages:

  1. Initial application
  2. Online competency tests
