This is true as I found out 3 years ago after house purchase, paid the deposit and in full for both meters when I moved in 6 weeks later no electric no meter either turns out PEA would not connect the cable to the metre as it was sub standard.
I was connected to the gatehouse and got free electric for 4 months and only when I refused any contribution towards the bill did they turn up with a 13,0000bt cable and spend a day pulling it in.
My satisfaction was short lived when on the meter end of the cable they had striped off the outer insulation and left only the blue/brown wires for over a metre PEA came back connected it up and said it was fine .
Just hoping there is enough slack in trunking to pull a metre through when the inner insulation burns off π€
