The electrical installation regulations to the Occupation, Health & Safety Act require the owner (or Lessor) of an electrical installation
to have an original, valid Electrical Certificate of Compliance (ECOC) in respect of the installation and may not sell the property in respect
of which the installation exists without one.
An ECOC is valid indefinitely provided no alterations or additions are made to the installation and can be transferred to the Purchaser of
the property provided it is not older than 2 years.
An ECOC older than 2 years cannot be transferred to a Purchaser and, whilst most agreements provide that the Seller will obtain a new ECOC,
provided the existing one is valid, there is no obligation on the Seller to do so.
The owner of a property can make it a requirement of any lease that the Lessee maintain the electrical installation and, in the event of
any alterations being made by the Lessee, which the Lessee pays for the issue of a new ECOC.
