Trev has answered your question.

If the service head and meter are more than 3 metres away from the CU then a switch fuse should be installed after the meter
Something like that anyway, I'm knackered and have a blinding headache so can't be bothered to go and get the proper info.
Sorry mate.

What's the point in that? If the cut out has a 100A fuse why then put two in sequence? Can't see the need. I only bother using a kmf if the mains is ran in 16 te and dumb it to 80A. Plus the dno supply a dual pole isolator.

Dear god!

I’m not surprised you have a headache Trev, I’ve just waded my way through this drivel.

The length actually varies between the different DNOs, on a recent meter move by ukpn the paperwork clearly states a maximum of 4metres.

The point is that the DNO specify a maximum length of tails which are allowed before the consumer must provide their own protective device. Generally this is 3 metres but some allow 4 and others 2.5

Do you do this for flat sub mains then? Can't see how the DNO would accept this.

Yes when we do the meter cupboards for flats we go from our kmf to the dual pole isolator supplied by the dno. But for houses we never use this setup. We just go from consumer to dual pole isolator. I never knew to be fair, but I still can't see the need for it.
