Wonder no more.As I mentioned in my original post ,I have not been very keen on deviating from "traditional hardwiring" ,but after just 4 days in to a rewire (5 bedroom), I am astounded at the enormous savings on labour as a result of going wireless ,plus the reduction in moving furniture , lifting floorboards etc and not having the incovenience of chasing and replastering etc.Homeowner loves it.
As always ,thanks for all the feedback guys.It was in line with my own feelings.While Ener-j would be a more practical option for me (available locally) ,the weight of popular opinion for Quinetic, edges the debate for me.
