What each reviewer checked
- Michael: Technical review of the exact current technical sentences on this page. It includes the unit, installation and board-scope boundaries. This is not legal review..
- George Opsenica: Owner presentation of this current page. Review of the current operating-practice sentences. The page is distinct enough as unit, installation and board-scope decision support. This is not a technical electrical review and it is not legal advice..
The extent is what you name
The extent of the inspection is the installation named in the instruction.
A converted building can contain more than one installation.
Seeing one distribution board does not show that it supplies only one flat.
Communal wiring is not automatically part of a flat's inspection.
One report does not stand in for a second installation that was left out of the instruction.
This page does not assume that every converted property has a separate supply, or that every flat has its own consumer unit.
Describe the scope before you book
| Fact | What to send |
|---|---|
| Unit | Flat number, floor and entrance |
| Inside and shared | Rooms in the unit, plus any hall or cupboard outside it |
| Board | Where the board is, and which unit you think it supplies |
| More than one | A second intake or a second board, if you can see one |
| Keys | Who can open the unit and any communal cupboard |
| How many | One dwelling, or more than one installation |
If you are not sure which board it is
Give the flat or unit number, the floor, and which entrance is used.
Say which areas are inside the unit and which areas are shared, such as a hall, a meter cupboard or a landlord's cupboard.
Say which distribution board you believe belongs to the unit, and where it is.
If you can see more than one intake or more than one board, say so rather than guessing from the age of the building.
Name who can open the unit and any communal cupboard that may contain a board.
Say whether the request is one dwelling or more than one installation.
If the scope is still unclear, send the address, the unit, a description of each board you can see, and who holds the keys.
One unit
Start with the flat number and the board inside it, if there is one.
A shared cupboard
A board in a shared cupboard may supply more than the one flat.
Two instructions
A second flat is a second installation unless it is named in the same request.
Arrange the named installation
When the unit and the board are named, arrange the inspection through EICR testing in London.
