Poles were high enough anyway, just happened to be renewed year before. Nie would have to move them at their cost anyway if they are in the way for farm buildings but didn't want to as would have needed stay wires out into field.Poles look new so I assume he paid to get them higher.
Although knowing NIE it would be an expensive option.
You are lucky that your electric suppliers would move the poles.
Ours require remortagage of the farm at worst and extensive trenching, paid for by you, at best.
