When we bought our cottage, we had an electricity pole and a stay about 3 meters from our back door. This would have prevented a future kitchen extension, and the wire stay was a complete nuisance – just the right placement to do some hurt if you weren’t paying attention. Next time the pole inspector came, I had a word with him about this, and asked nicely if there was any chance they could move said pole to garden/field boundary and run cable underground.
Within a week three lads, a supervisor and a mini digger turned up and moved pole/stay about 35m away to the boundary, and dug a trench to take the cable underground to the outbuilding attached to the house, brought in an electrician and re-wired the consumer unit. Total cost – 3 slabs of beer, 3 boxes of biscuits, and a bottle of whisky for the supervisor. I think we were probably very lucky as we’d earlier been quoted 12k to take the cable underground from the next pole about 100m away in next door’s field.
