UKPN service head to smart meter - Advice and options?

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

    I'm almost of a mind to get the client to bite the bullet and get a new separate supply and remove the problem from access, sharing a cutout with the downstairs flat and the loop in, etc. Or do you think that's excess and unneccesary cost. Install a new cabinet outside, move the smart meter outside as well; install a Lewden switched fuse in there and run a 25mm2 three core SWA externally and enter the upstairs flat at a similar point to where the old VIR cables exit the brickwork and enter the CU direct?

    What's the actual demand for the flat? I suspect a completely new supply is going to be expensive (especially if the DNO see it as an opportunity to charge for re-inforcing their network). It looks like it's been OK on "half shares" of a 60A supply until now - does it really need a 100A supply?


    If that's the alternative, then a small Ryefield, SWA or split-con up to the flat and red-head cut-out will probably start to look financially attractive...

    Possibly not 100A Andy, but there has been talk of an EV charging point and power shower by the new owner so suspect that the 'half shares' might be stretched ...

    Ryefield, etc. would be more financially attractive than a new supply ... certainly for their pocket!
