Voltage drop poser

[TeMac]

Hi all…here we have approx 236v in pre meter. When a heavier load (kettle, freezer, shower, toaster etc…) kicks in it drops to approx 130v and obviously fails to work (and lights dim).

Isolated everything and used just 1 said heavier load item and always a drop occurs.
OK ok lighter loads ie lights etc….

Electrics not my specialty as I’m a Gasman (so used to working safe).
Just happened yesterday. Very recently workmen dug 2 x 3ft holes in street for some unknown reason and covered (maybe not related nor electrical).
Hopefully a couple of pics posted may help.
Could this be supply to property ?

Thanks

Could this be supply to property ?

Definitely.

Contact the network operator to repair. Call 105.

Yes, and don't tell them you have had the cut out apart, and don't do it again, the supply cable upstream is likely fused at circa 400A at the transformer fuseboard. So f***ing up or slipping would result in a very big bang indeed!
