Communal areas – for the four years between EICRs we visit all out communal areas and carry out a visual check including EM light check and smoke checks.
For quick turnaround voids like interim accommodation then we always do an EICR due to the tenants. Sometimes drugs are hidden in sockets etc.
The other area is HMOs where bedrooms are let in a building. We do not carry out a full EICRs just visual checks of the installation in that room. Usually carried out by the building manager not an electrician.
Hope this helps.
