But that still does not excuse the meter fitter leaving a service disconnected - does this count as an illegal disconnection of supply ? If it had been me, I'd have been on the phone "very quickly" and expressing my dissatisfaction in such a manner that the fitter would probably get a phone call to turn around and re-visit the jobShould be noted where the bodged up wiring was at the bottom of the old meter, both sets of outgoing tails are unharmonised pre-2006 cables.
What the meter fitter should have done is to observe the issue before he started and either :
- Put both tails into service connector blocks (a.k.a. "Henleys" in the same way that all vacuum cleaners get called "Hoovers"), and connected those to the meter with single tails
- Informed the customer of the problem and cancelled the install.
As already mentioned, the best option now would be to get your supplier to come out ("like yesterday or I'll sue") and fit an isolator switch. Then get an electrician (preferably a better one than did the original bodge) in to re-do the tails from the isolator to the two CUs, using the correct service connector blocks to split the tails. Make it clear that "in a week or three" won't do, and you are already going to make a complaint to Ofgem about your illegally disconnected supply if they don't sort if NOW - I suspect your typical call centre operator is likely to perk up somewhat at the opportunity to be named in such a complaint (make sure you get their name early on in the call).
It might be possible, given the hassle they've caused you, to persuade the guy that comes to fit the isolator to put in a couple of connector blocks and re-connect the second board. That depends on who gets the job, how overloaded he is that day, and whether you have the right sort of biccies to offer him.
