So, we're living in a period property so the tree was clearly planted much closer to the house than would be allowed nowadays.
It's a mammoth of a tree - significantly taller than our 3-storey house and a large trunk and canopy. We have had it trimmed back some years ago by 1/3 (had to apply to do it as in conservation area) and it was still bloody large. It's fairly healthy though seems to have some sort of weird insects but, mostly, I'm concerned about the proximity to our house as if something happened, that would be it for probably a good 1/3 of our house!
A couple of years ago, another large (but not at this scale) tree suddenly started creaking and so was a danger and got the council to send someone around that day.
My question is, what is the likelihood of getting a council to agree to having a tree like that culled? It's literally only metres from our house!
