UKPN service head to smart meter - Advice and options?

Former Community Member

Situation - first floor maisonette

UKPN Service head (60A fuse) TN-S is located in ground floor flat with no access for first floor.  Riser cables (VIR badly degraded) run inside brickwork up to another cutout fuse (60A).  Modern cables then loop into smart meter.  UKPN say they are not responsible for the riser - EDS 08-1103 section 6.1 - even though EPN as it was then installed it (although the cutout is theirs and technically only they are allowed to remove the fuse - my thoughts?).  UKPN won't pay for the work so that sits with the client unless anyone can tell me differently?

So, what's the best way to achieve this?  Need to upgrade the cable to 25mm2 (and probably ask to upgrade fuse to 100A) and it's not practical to start digging out the walls, not least because prolonged access to downstairs is not really an option.  Therefore external?  Best method/option?

Thanks in advance

    As Andy J says there are 3 supplies from the old PILC cable. As this is UKPN the supplies are PME. That bare 3/ 029 is not of sufficient CSA for an earthing conductor. Cotton covered VIR tails are not insulated an sheathed.


    I think the solution would be a new DNO supply in to a common area or external feed pillar, an isolator to a 3 way Ryfield, 3 new un-metered BNO supplies to series 8 heads with the earth neutral links removed, the cut outs fitted with Red Head solid links insulated and sheathed singles to each meter.
