Test house audits

Test houses must be approved by us to calibrate, install, commission, and certify metering installations in accordance with Part 10 of the Code.

In this section:

More information about test houses is in the metering section.

Audits should be carried out and submitted as part of the application for approval:

when a test house first gains approval
on the date that we’re advised that an audit should take place
at any time at the request of the industry participant, the market administrator (the Authority) or an auditor.

The audit shows if a test house:

has the facilities and procedures to consistently meet the requirements of the Code
has a fit and proper person for approval to act as an approved test house
addresses any other matters raised.

Test houses fall into two categories: class A and class B. The categories have different requirements.
