Link between activity type and authorisation

Companies which only carry out certain types of electrical installation work can specify in their self-audit scheme which of these activity types they are involved in.

The self-audit scheme only needs to describe the relevant activity types, and the compliance officer is not required to have a full authorisation.

High voltage activity types

For the activity types in the high voltage area, the compliance officer must have a full electrical contractor authorisation, A.

Low voltage activity types

For the activity types in the low voltage area, the compliance officer must have either a full electrical contractor authorisation, A, or an authorisation for low voltage, AL.

Limited activity types

For some limited types of work involving the permanent connection and disconnection of equipment (machinery, heating, cooling and ventilation systems, lifts, gates and escalators), the compliance officer must have either a full electrical contractor authorisation, A, an authorisation for low voltage, AL, or a limited authorisation, B.

Special activity types

The cable laying activity type is exempted from the requirement to have a compliance officer. The self-audit and registration requirements remain unchanged.
