what the meter fitter has done here is exactly right.

I would have thought it would have been better if they'd replaced the original DP isolator with the 4P one in the same position - there would then bean obvious single point of isolation and the customer's electrician would have been able to connect in the extra two tails as was obviously intended without having to extend/replace them.

What's been done may well tick the boxes on a management checklist, but seems to lack common sense, I'd say.

I don't disagree that it's lacking common sense, but it's drummed into them to follow their process and never deviate from it. I've seen meter fitters that have received as little as 10 days training before being unleashed on the world, and they're well aware that their only defence under EaWR is to say they followed their company processes.

I don't think the meter fitter could have removed the two pole isolator without disturbing the outgoing tails and that could have loosened connections etc.  Leaving the final connection to the isolator to the customer's electrician puts the onus on them to ensure that the installation is safe and compliant.  40 years ago the meter fitter would have done some basic tests on the installation such as polarity and insulation and earthing but the world has changed and electricians are now responsible for signing off their work.  The provision of isolators makes for a clear boundary and removes the need to coordinate attendance but can lead to messy looking installations like this too.

If the cut out had been fitted to the left a bit that would have enabled a tidier installation but that was fitted by the DNO......... with not enough thought for what comes afterwards.
