Simply insert a tick into the appropriate box indicating the inspections made. Add a ‘N/A’ to the box where the inspection is not applicable. You may feel it is appropriate to insert ‘LIM’ (for limitation) into a box where the inspection type is limited to certain areas. If this is the case, you should create your own ‘LIM’ legend on the schedule. The schedule should be used with an associated Electrical Installation Certificate or Periodic Inspection Report. F 4.3.6 Recommended frequencies of next inspection The frequencies of ‘next’ inspection are shown in Table F 4.1 and reproduced from IEE Guidance Note 3. Table F 4.1 Recommended initial frequencies of electrical installation inspections.
