Another aspect of dereg. in the U.K. has been the almost complete dropping of basic safety tests.
As I've said several times, we have no permits or inspections, and anyone can do a complete re-wire.
Back in the "old" days, when the guy from the Electricity Board (as it was then known) came along to install the meter and connect or re-connect power, he would at least carry out a few basic tests: Check for ground on main ground busbar, insulation test line-to-neutral and L/N to ground, etc.
If these tests failed on he saw anything else considered dangerous, the utility had the right to refuse to connect power.
Now that the 200 different companies are run by the bean-counters instead of the engineers, they don't bother with any tests. Connect the meter, in goes the service fuse, and if it doesn't go bang, they pack up and leave.
Why should they bother? If there's 5A leakage flowing to earth, all the more profit for them!
