Calculate Your Party Wall Costs
Frequently Asked Questions
How much does a party wall surveyor cost in the UK?
Party wall surveyor fees typically range from £700 to £1,500 per surveyor for a straightforward case. The building owner's surveyor and the adjoining owner's surveyor each charge separately. If an agreed surveyor is appointed (one surveyor acts for both parties), the total cost is usually £1,000–£2,000. The building owner normally pays all costs.
Who pays for the party wall surveyor?
Under the Party Wall etc. Act 1996, the building owner (the person carrying out the works) is generally responsible for paying all reasonable party wall surveyor costs, including those of the adjoining owner's surveyor. This applies even if the adjoining owner appoints their own surveyor. Costs are typically determined in the party wall award.
What is a party wall award?
A party wall award (or agreement) is a legal document prepared by the party wall surveyor(s) setting out the rights and obligations of both parties, the schedule of condition of the adjoining property, and the method of working. Preparing an award adds approximately £800–£1,500 to the total cost, depending on complexity.
When do I need to serve a party wall notice?
A party wall notice must be served at least two months before work begins for party wall works (such as work directly on the party wall), or one month before for excavations near a neighbouring building. Notice is required for works including building on or near a party wall, loft conversions, basement excavations and rear extensions near a shared boundary.
Can I avoid party wall surveyor costs?
Yes, if your neighbour signs a party wall agreement (consent) in writing within 14 days of receiving the notice, no surveyor is needed and costs are zero. If they dissent or do not respond, surveyor involvement becomes mandatory. Good neighbourly communication before serving notice can often avoid formal proceedings.
