What to prepare for a commercial EICR in central London

• The premises

  Office, shop, studio or mixed use. A commercial premises is not treated as a large flat.

• The boards

  How many distribution boards are in scope, and who holds the keys.

• Occupation

  Whether people will be working, and which supplies cannot be off at the same time.

• Phasing

  If the whole installation cannot be isolated together, say which areas can be done in which order.

• The building

  Concierge, loading bay, or a landlord's riser that is not part of the tenant's demise.

• Parking and escorts

  Say what the building actually requires. Do not assume a van can wait on the street.

• Critical supplies

  Name anything that cannot be off while people are working: servers, tills, refrigeration, alarms, or a landlord's service that is not yours to switch.

• Common parts

  A riser, intake, or landlord's board may sit outside the tenant's demise. Say who controls that door, and do not assume it is part of the unit.

Send the full address, what the premises are used for, and whether people will be in the space on the day. Add how many distribution boards you know about, where they are, and who holds the keys. If you have a previous report, a circuit chart, or photographs of the board labels, send those too. Say whether the chart has been checked or is only a guess.

Then say what cannot be isolated at the same time. An occupied office may need workstation circuits planned around the people using them. A shop may need tills and refrigeration thought about before a board is switched off. A workshop may need machinery isolated by someone who knows the plant. Those constraints belong in the quotation, not in a surprise on the morning.

If the building wants an escort, an induction, or a loading bay booking, say so. Parking and waiting restrictions are part of the access, not a detail to discover from the kerb. This page does not offer 24-hour attendance, a guaranteed night shift, or a turnaround. If a particular building can only be isolated outside its working day, that is agreed on the quotation for that building.

The Electricity at Work Regulations 1989 are a workplace duty to prevent danger so far as is reasonably practicable. They are not the private-rented rule that sets an inspection at no more than five years for a specified tenancy.

For a specified tenancy in England, arrange inspection and testing by a qualified person at least every five years, or by an earlier date stated in the report. Provide the required report before a new tenant moves in. Government guidance explains when an existing valid report can be used on re-letting; check its findings, next-inspection date and any changes to the installation rather than assuming that every new tenancy needs a new EICR.

This page does not offer 24-hour attendance, a guaranteed night shift, or a turnaround. If out-of-hours work is possible for a particular building, that is agreed on the quotation, not assumed here.

Ask for the inspection on the commercial EICR page. The central London place pages start from EICR in central London.
