The Minor Electrical Installation Works Certificate (Minor Works Certificate) was first introduced in 1993, in recognition of the fact that the then combined ‘Completion and Inspection Certificate’ was perceived to be too comprehensive for minor electrical installation work.
Minor work is generally considered to be electrical work that does not include the provision of a new circuit, such as an alteration, addition or extension to an existing circuit. A properly completed Minor Works Certificate is recognized by BS 7671 as providing the necessary certification for such work.
Since its introduction, the Minor Works Certificate has been used extensively but, on occasions, it has also been used inappropriately.
A separate Minor Works Certificate should be issued for each circuit altered, extended, or added to (Regulation 741-01-03 refers). Where installation work falls outside the limited scope of the Minor Works Certificate, an Electrical Installation Certificate or, where appropriate, a Domestic Electrical Installation Certificate, should be issued.
The Minor Works Certificate is available in the ‘red’ and ‘purple’ serially-numbered controlled version for NICEIC Approved Contractors and Domestic Installers respectively, and in the green, uncontrolled version for use by electrical contractors not enrolled with the NICEIC and by NICEIC Approved Contractors and Domestic Installers working outside of the scope of their registration (such as in hazardous areas).
