UKPN service head to smart meter - Advice and options?

Former Community Member over 3 years ago

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

What UKPN will want to see,

1) a wire sealable fused isolator downstairs supplied by new tails from the DNO head (replacing the bolts with ones with drilled heads for lockwires or some seal they consider equivalent).

2) A length of SWA from the fused isolator to upstairs

3) Upstairs a a wire sealed "red link" cut out. (if need be for mechanical reasons, an adaptable metal box or similar with Henley block inside to take the SWA to tails to supply if the size of SWA wont fit the head chamber directly)

4) From the red link to the upstairs meter, in the existing ordinary tails.

5) A piece of paper from the BNO electrician (you ?) that says the riser is to BS7671.

Then they will connect the tails at the lower end to the company fuse.

For now, tape only if you can do this with no disturbance split flexi conduit is another kind of patch.

Cheers mapj1. :)

I'm not going to attempt this one myself; I'll assist and learn for the next time ... but good learning for me to read the different options.
