This isn't something I'm currently faced with by the way - I'm just researching as I've not found the 'right' way to do shown anywhere.
I've seen videos of guys just cutting the seal and pulling the fuse themselves, but I've not managed to find anyone describing the process of requesting the...
Because I've worked on the industrial side of things for over 20 years and now in the middle of a career change as personal circumstances have changed.
What is everyone doing to safely isolate when you are faced with a consumer unit change and there is no isolator between the CU and the supply cut out? I assume it Is a case of contacting the DNO to come out? How long does this take and what are the fees, etc?
