This is linked to my other thread about silicone render. The wall to be treated includes a meter cupboard (originally gas and electricity, now electricity only). This was covered by a rather tatty home-made cabinet, and on removing it I found this:
A crumbling wooden frame with (on the electric side) an even more crumbling backboard.
I plan to remake the frame just around the electric meter and brick up the old gas cupboard (the inlet is dead) and fit a new front cover. I'd also like to replace the backboard, but to do so I'd have to open up and release the two boxes which I have a suspicion is illegal (not to mention dangerous). I'm perfectly willing to get in a qualified person to do it, but is it a job for an electrician, a builder, the local electricity board, or all three?
Many thanks.
