This is not office planning
An occupied warehouse or workshop is planned around industrial distribution, plant, loading or working areas, and when those places can actually be opened.
Use the commercial EICR enquiry and include the industrial-site details needed to plan the visit.
Warehouses and industrial units receive a site quotation reflecting the installation and agreed testing arrangements.
If the premises are primarily an office, use the occupied-office planning guidance instead.
What the inspection is about
The inspection covers the fixed installation in the extent that is agreed.
Name the distribution boards that serve the warehouse, workshop or unit, including boards in plant rooms, mezzanines or loading areas.
A three-phase supply, where it exists, is a type of supply. It does not by itself decide the codes or the price.
A classification code should not be inferred from a building type, a photograph or a description of plant. The inspector attributes codes from the inspection and testing evidence.
Plant, loading areas and isolation
Say which plant rooms, machinery supplies or process equipment must stay on, and who can open those rooms.
Say which loading bays, working floors or yards are in the visit, and whether vehicles or operations will still be using them.
Access to a locked board, a plant room or a working area is agreed before that place is opened.
Isolation, where it is needed, has to be planned around the equipment that must stay on. Agree the isolation plan with the electrician and the responsible site contact before testing.
Agree the testing window, any shutdowns and operational arrangements with the office and responsible site contact.
Boards
Name the distribution boards that serve the warehouse, workshop or unit, including boards in plant rooms, mezzanines or loading areas.
Plant
Say which plant rooms, machinery supplies or process equipment must stay on, and who can open those rooms.
Loading and working areas
Say which loading bays, working floors or yards are in the visit, and whether vehicles or operations will still be using them.
Access
Access to a locked board, a plant room or a working area is agreed before that place is opened.

Build the warehouse or workshop site brief
Describe the installation and the working environment before the office quotes the inspection.
Site and installation
List the units, boards, mezzanines, yards and shared areas you want included.
Production and machinery
Identify machinery and supplies needing an agreed plan. Explain any distinction between the building installation and equipment-specific testing.
Working access
Flag height restrictions, vehicle movements, restricted rooms and site-induction requirements.
Planned window
Give potential working periods, existing reports and the site contact able to agree access and interruption arrangements.
