My Uk house has economy 7 electric just 14p a kw/h.................however the extension lead to Thailand drops the voltage down to 8V, gonna sell the place soon and it should be a big selling point for any ev buyer as they dont let you have economy 7 tariffs now, they have some crap other deal. Just got to leave Thailand for 6 months before bringing the money in as I aint giving anyone the proceeds when i sell it
