Minor Electrical Installation Works Certificates (MEIWC)

The type of electrical certification or report you receive depends on the extent and type of electrical installation work, inspection or testing that is being carried out.

Electrical certification for new installations, alterations or additions

Minor Electrical Installation Works Certificates (MEIWC) provide the person responsible for the safety of an electrical installation (usually the building owner) with a certificate declaring that the new electrical installation, alteration or addition has been carried out in accordance to British Standard BS 7671 and is safe to use.

Landlords should keep hold of electrical certificates. In the event of a claim that injury or fire was caused by an electrical installation in a rental property, electrical certificates are documentary evidence which help show that the landlord has been responsible in their duty of care by having electrical installations inspected and tested to a satisfactory standard of safety.

The electrical installation works certificate (EIC) indicates whether the electrical work that has been carried out is:

  • New – the whole installation has been installed as new, a complete rewire has been carried out, or a consumer unit (fuseboard) has been replaced.
  • Addition – an existing electrical installation has been modified by adding one or more new circuits.
  • Alteration – one or more existing electrical circuits have been modified or extended (eg, the addition of a electrical socket), or items such as a consumer unit (fuseboard) and switching equipment have been replaced.
If a new electrical circuit is being installed, an Electrical Installation Certificate (EIC) must be issued! Where an alteration or addition is carried out but does not include a new circuit, a Minor Electrical Installation Works Certificates (MEIWC) or an Electrical Installation Certificate (EIC) may be used.
