What a party wall surveyor does in City of London
A party wall surveyor administers the Party Wall etc. Act 1996 for work that affects a neighbour. For homes in City of London, that most often means rear and side extensions on or near the boundary, steel beams cut into a shared wall for a knock-through or loft, and foundations dug close to next door.

Party wall surveyors in City of London: common questions
How much does a party wall surveyor cost in City of London?
Published guides put a straightforward appointment at around £1,000 plus VAT per surveyor, with most homeowners paying £700 to £3,500 in total. The work, the number of neighbours and whether one or two surveyors act make the biggest difference.
Who pays for the party wall surveyor?
The building owner carrying out the work normally pays the reasonable costs of their own surveyor and of the neighbour’s surveyor, where the work is only for the building owner’s benefit.
How much notice do I need to give my neighbour in City of London?
The Act sets two months’ notice for work to a party wall and one month for excavation near a neighbour’s foundations or building a new wall on the boundary line. Notices must be in writing.
What happens if my neighbour does not reply?
If a neighbour does not respond in writing within 14 days, a dispute is treated as having arisen and surveyors are appointed to agree an award before the work goes ahead.
Can one surveyor act for both of us?
Yes. If both owners agree, a single agreed surveyor can act impartially for both, which usually costs less than two.
Does planning permission from City of London cover party wall matters?
No. Planning decisions are made by the local planning authority for City of London, while party wall matters are dealt with separately under the Party Wall etc. Act 1996.
I have received a party wall notice in City of London. What should I do?
Note the date it was served, because you have 14 days to reply in writing. You can consent, or dissent and appoint a surveyor, whose reasonable costs the building owner normally pays.
