Our smart meter is fixed on an L bracket, in the cabinet. The L bracket holds the meter by the two unions only, rather than supporting the meter from below at the base. The rubber feet are some 2" clear of the cabinet base.
I thought I read something about the regulations required it to be properly supported, including a (second) bracket to support it at the bottom?
Thing is, our latest energy supplier cannot access the OVO smart gas meter remotely, so they have agreed with me to fit a replacement which they can work with. I might as well make sure it is properly installed.
