We agreed with neighbours on one side to appoint a surveyor to make a party wall award, as a safeguard around any potential damage from our loft conversion. The (shared) surveyor was appointed and carried out a schedule of condition on the same day our builder started works. The actual party wall work is already complete with no apparent damage. Obviously the builder should not have started works. The surveyor is now trying to halt all works before making an award although I don't believe he has any statutory right to stop works, my understanding is our neighbour would have to injunct. We and the neighbour are keen to reach an award however the surveyor is continuing to request additional information from the builder and to perform other unspecified tasks that he says will increase his bill, while refusing to describe those tasks or to give any anticipated timing on the award. My concern is he will run up the bill and maybe not even issue an award. What can we do?
