Mr D Purnell
I have recently used Crossman Ecology for an old farmhouse which had bats present – they were recommended by my architect who had used them on another job. I have to say they were extremely good.
Not only do Alex and Fairbrass have a fantastic knowledge of protected species they take a very sensible and practical approach when it comes to developing.
I would definitely use them again if required and would recommend them to everyone.
