Same thing exists in the US, but they change the current ratings.

Poke-in wire trap has never been allowed in UK premises wiring.
US-type wrap-around screw terminals are not used here for perhaps
30 years now in premises wiring. Terminals are all of the type
where you poke wire in a hole and a clamp screw is done up to grip
the conductor and make electrial connection. Wirenuts/Screwits,
also popular in the US, are not allowed here.

That's correct - domestic electricity is only charged for real
power used. However, EU legislation is tightening up on the
amount of harmonics various appliances and lamps are allowed
to produce. Quite severe flattening is easily visible on most
EU mains supply sine waves now, due to rapid spread of appliances
and lamps which only draw power at the very peaks of the mains
