BS 7671 Minor Works Documentation Course

Additions and alterations BS7671 Minor Works Documentation Course

The Minor Works Certificate is intended to be used for additions and alterations to an installation that do not extend to the provision of a new circuit. Examples include the addition of socket-outlets or lighting points to an existing circuit, the relocation of a light switch etc.

It may also be used for the replacement of equipment such as accessories, motors or luminaires, but not for the replacement of distribution boards or similar items. Appropriate inspection and testing, however, should always be carried out irrespective of the extent of the work undertaken.

There can often be confusion in the completion of the documentation required and this course will ensure candidates have a clear consistent approach.
