We contacted planning office before we put in an offer on our site, inhabitable house on acre of land, lots of trees plus site next to wooded area. Told we would need ecology survey, due to house being empty for over a year and the amount of trees on and near site. Asbestos survey due to being built 1960s. Tree survey due to 4 trees having a TPO who would advise root protection. Ecology desk top survey and visit survey was done within 6 weeks and can be done at anytime of the year, but 2nd dawn dusk survey has to happen between may and July, we booked ours in January and the earliest they could do was end of june. Planning had also advised that demolition should happen between oct-feb, we are in Scotland, the ecology surveyor said the same thing. There is a website that you can use interactivity where you put your postcode in and they tell you if bats have been in your area. I will look for it and post, no bats in our case but we had Jackdaws. Regards utilities do not underestimate how long this takes and a shambles of service. We have moved electrics to box at boundary you would not believe the amount of calls, effort and time this took although our experience is very familiar to those here. Still have not managed to get water moved. We have also found it hard to get quotes for some surveys from ground investigation to tree survey with lots of chasing a top tip is to ask those who are working for you as the bat woman gave us a tree survey contact and put in a good word which meant he called and was able to fit us in. The tree protection officer gave us 3 contacts but only one replied and said they were not free for 3 months.
