A new socket, lighting point, circuit or fixed supply has to work with the wiring and protective devices already in place. The route, load, access and condition of the installation all affect the final scope.
Available circuit capacity
The proposed work is assessed against the circuits and protection already serving the property.
Suitable wiring routes
Access and cable routes influence how the installation can be completed and what making-good may be needed.
Existing protective devices
New work may require changes where the current fuse box or consumer unit cannot support the agreed addition.
Where circuit protection needs to change, a separate
fuse box or consumer unit assessment
can confirm the work required.
