Hi all. I bought a house last year and it turned out the extension isn't up to code. No problem - we decided to knock the whole thing down and make it larger. Planning permission in (just waiting), building control notified, architect and builders all in and ready and we are in the process of contacting structural engineers. Everything will be done properly. I live in a semi-detached house. My neighbour and I had a conversation and he was happy for the extension to go ahead. Fast forward to 2 weeks later I recieve a very formal letter from a party wall surveyor that he has instructed. I have no issue with him instructing anyone, but a heads up would have been nice given that until now everything has been quite friendly. My main issue is that he has instructed a party wall surveyor that isn't even RICs regulated. Can I refuse this particular surveyor? Everything I have read says that I need to pay as it is me having the work done. I do not want to pay for someone I feel isn't up to par. I can get my own surveyor but that then means I have to shell out for 2 surveyors, possibly 3 if the two do not agree. Any information would be appreciated.
