Got my 240v hook up installed. Sparky coming to check it all out over the weekend

. Just as I finished the boss woman came out (when the work was done) and said "Is it the same electrickery as we have in the house now?"

When I said "Yes dear, sort of" she suggested getting the oil filled radiator out of the loft and fastening it in the van!
My questions are:
1) When you use 240v hook up at a campsite, do you pay a set fee regardless of how much power you use, or is it metered?
2) Anyone used an oil filled radiator in their van? Any problems or, more importantly, risks?
Thanks
