Commissioning certificates – evidence

Certificates demonstrating compliance with any relevant standards are acceptable for the commissioning criteria, where they cover all the systems referred to in the criteria (hot water, heating, ventilation etc.) and any relevant commissioning best practice guidance has been complied with.

The ‘commissioning best practice guidance’ outlines how to carry out commissioning for various different systems that may be present. Some of the guidance is more appropriate for complex systems and often won’t be relevant. The person or persons carrying out the commissioning activities is expected to be familiar enough with the standards referenced, to determine the ones that are relevant to the systems they are commissioning.
