Hi, i'm fitting an electric towel radiator in the downstairs loo. My plan is to use a flex out on the inside zone 2 on the otherside of the wall (in the hall) put a fused spur timer switch to control when it comes on. My question is does it matter how high I mount the fused spur timer switch? Ideally i'd like to mount it just above the skirting board so that its not in the way but I can still see it to adjust the timer.
