DNO cables indoors

[Steve]

How far will DNOs run their cables inside a house to the head?

All the photos i've seen seem to indicate only a couple of feet at the most. Has anyone come across any instances of greater distance than this?

Every DNO is different. WPD will run 3m, surface mounted, with other restrictions too.

The PILC in my brothers house runs for about 6 or 7 meters under the floor before the head.

I don't think there is actually a limit, and the runs are usually short just to make it easy for the DNO.

cheers. my mums just smoosing over an extension, but the proposal would put the meter and head smack in the middle of the house. The outdoor cabling would also need moving (it runs overhead, "through" the new extension). Wondering if its worth the effort of moving the head and meter to a new box outside as part of the project, but this would mean the DNO running their cable round the front, something we dont want.

Isn't that rule to do with the meter tails, not the cable pre cutout?

I thought that pre-electric meter the DNO have their own rules / regs?

Yeah, they're now governed by ESQCR 2002.

What regs governed their installation in years gone by I'm not sure.

But I saw one the other day where the cable ran under the floor for a good 9 metres, then from the cut out a pair of fabric covered, rubber insulated singles went back under the floor, "protected" by an unearthed conduit. This then ran a further 5m to next door.

The house was a huge, detached Victorian villa.

Ours runs along the wall under the floor from the front door to the undestairs cupboard (i've not measured how far this is, but it's not a trivial distance) and then comes up to the service head in the understairs cupboard.

but then the cable and service head look very old (the head has plastic fuseholders and neutral termainls but the spreader box appears to be cast iron). The main earth comes from a ring crimp on one of the screws for the entry clamp on the service cable).

Have they told you how much that will add to the cost of the extension?

The DNO's supply cable in my house runs underground from the road in front of the house into the floor void under the living room, into the dining room & then up into the kitchen, where it comes up through the kitchen floor into the service head. The length is probally approx. 10m of lead & paper sheafed supply cable.

Only 2 meters with United Utilities in North West.

And ban, I'm not sure, but AFAIK, YEDL/CE use sobcontractors. A couple of our neighbours have had their supplies moved - they run house-to-house here, so the overhead span concerned only runs from ours to next door. I cant see the charge for this being extorionate, but I know they punish them on meter moves.

Yep, YEDL / NEDL / CE use subbies.

We had a new TP supply installed on a job in Harrogate.

The lads drove from Tyneside to do that job for us
