Electrical Installation and

Minor Works Certification

Upon completion of any new electrical installations; alterations; or additions, 3L Electrical have the capacity to provide their clients with either an Electrical Installation Certificate (EIC) or a Minor Electrical Installation Works Certificate (MEIWC).

Electrical Installation Certificates and Minor Electrical Installation Works Certificates act as a guarantee to our clients that the new electrical installation; alteration; or addition, is safe to use at the time it was put into service.


It is essential to store these certificates in a safe place as, in the event of a claim that injury or fire was caused by an electrical installation, certificates can be used as documentary evidence to show that the installation had been installed to a satisfactory standard of safety.  These Certificates can also provide a basis for any further inspection and testing, as they can help save on costly exploratory work which might otherwise be needed in future.

An Electrical Installation Certificate will indicate whether the electrical work that has been carried out is:
 

  • New - where the whole installation has been installed as new, if a complete rewire has been carried out, or where a consumer unit (fusebox) has been replaced.
     

  • Addition - applies if an existing installation has been modified by adding one or more new circuits.
     

  • Alteration - applies where one or more existing circuits have been modified or extended (for example to add a socket), or items such as a consumer unit (fusebox) and switching equipment have been replaced.
     

Electrical Installation Certificates must be issued for all new electrical installations and may also be required for an alteration or addition to the installation dependent upon whether or not a new circuit has been installed. Where an alteration or addition is carried out but does not include a new circuit, a Minor Electrical Installation Works Certificate may be issued instead.
