i live in the Durham area, north east could anyone inform me of the correct procedure for getting an isolator fitted between the meter & ccu. All sparks i have spoke to, pulls the fuse themselves and not one of them has ever phoned for an isolator. while i'm not to concerned about pulling the fuse, my problem is, sometime putting lucy blocks in connecting my tails for the consumer unit (25mm) to there tails sometimes 10mm as i dont want to snip the meter seals, any help would be appreciated
