We were working in a house today where there were other electricians on site. The customer had basicly called us in for electrical jobs that they needed done, And the other electricians were working for the builder that was there for a new extension. We did ask the customer why this was and they told us that the builder gave a price for the complete works for the extension, which I felt was fair enough.
If you look at the picture I took you can see a connector block taped up which is the wiring of the other electricians worklight.
I wonder if their health and safety and risk assessment policy is up to date lol !
