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

    Hicky59, have you considered sending your photos to UKPN with, of course, the customer's permission?


    Surely that has to be C1. If I found a line conductor like that, and had survived doing so, I would feel obliged either to isolate by removing the main fuse (which is problematic given that two dwellings are served by it) or remain present until the DNO turned up.


    Not in a month of Sundays would I attempt to remedy the situation - R14 of EAWR 1989.


    I might add that SSE has a sensible policy regarding removal of the main fuse. Registered electricians may do so, but then apply a sticker by way of re-sealing. And qualified electrician may remove the main fuse in an emergency (such as an overheating CU). Mind you, if the CU is bubbling away, I wouldn't be too keen on pulling the fuse without good PPE.
