I have been involved in a PWA "negotiation " between my surveyor and the adjoining owner's surveyor for 3 years! My neighbour (AO) has made it clear she does not want me to build a side return unless it is like hers. Our houses are pretty bog standard Victorian terraced houses and I am extending into side return and loft. AO appointed a surveyor who has strung queries out for 3 years!. Plans approved by council etc. The costs are over £10k - which I have to pay. AO's PW surveyor took several months to provide time sheets for his fees and now says that he charges in 15 minute units eg he looks at something for 5 mins and charges me for 15 minutes. Is this a usual the fee structure for PW surveyors? My Surveyor says it is not unknown that surveyors charge in 15 minute units. I have never been sent any details of how the AO party wall surveyor charges until he produced these outrageous charges. We are in Wandsworth. Also he constantly comes up with issues in a drip feed manner thus charging more as he says he just noticed X or Y and spent more time looking at the issue. Any help on whether this guy's fee structure is usual would be great. Even after 3 years looks like a third surveyor will have to be called in. ðŸ˜
