I need to move my consumer unit (only by 500mm or so) which means new tails. I have no DP isolator between the supplier’s cut out and my consumer unit. I intend cutting the seal on the cut out and pulling the fuse. I will then fit a 100A DP switch to the existing 25mm tails from the cut out, then new 25mm tails from the DP switch to my new consumer unit (as well as a new 16mm earth cable of course). My question is, whats the score with cutting the seal? Years ago (when I was a jobbing spark), we would just cut the seal off... but now sure what you guys do nowadays...
