- Origin of the installation
- Condition of the main switch, metering equipment and incoming supply cables, confirmation of the earthing arrangement — TN-S, TN-C-S or TT — and measurement of external earth fault loop impedance and prospective fault current at the origin.
- Distribution boards and sub-distribution
- Condition, labelling, accessibility and circuit charts, protective device selection, RCD arrangement and discrimination, and insulation resistance testing. A multi-floor hotel typically has a main board plus a board per floor, and the floor boards are where undocumented alterations accumulate.
- Surge protection
- Regulation 443.4.1 requires protection against transient overvoltages where the consequence could result in serious injury to, or loss of, human life, or in significant financial or data loss. For all other cases protection is required unless the owner of the installation declares it is not, on the basis that any loss or damage is tolerable and the risk is accepted. On a hotel with life safety systems on the same installation, that declaration is a decision the responsible person has to make consciously — the risk-assessment method that used to justify omission was withdrawn.
- Guest bedroom circuits
- Socket-outlet circuits, lighting circuits and any en-suite circuits, on an agreed sample of bedrooms. The sampling rate and the rooms actually accessed must be recorded on the report, otherwise the next inspector cannot tell what was covered.
- Plant rooms, lift motor rooms and back of house
- Plant rooms, lift machinery rooms, boiler rooms and service areas are all in scope. The lift supply is inspected as part of the installation; the lift itself is maintained separately by a lift engineer and is outside the EICR.
- Emergency lighting and fire alarm wiring
- Both systems are part of the fixed electrical installation. The inspector verifies the supply arrangements, circuit protection and wiring condition, and reviews the test records, without substituting for the separate BS 5266-1 and BS 5839-1 servicing regimes.
