In short
The cost of a party wall award depends on how many neighbours are involved, whether one agreed surveyor or two surveyors act, how complex the work is and whether engineering review is needed. The building owner normally pays all of it, including the neighbour's surveyor.
The cost components
- Serving notices
- Schedule of condition for each adjoining property
- Preparing and agreeing the award
- The neighbour's surveyor's fees, if they appoint their own
- Engineering review, and the third surveyor if needed
What pushes costs up
- More neighbours: a mid-terrace loft usually means two awards
- Two surveyors instead of one agreed surveyor
- Basements, piling and deep excavation
- Missing or late structural drawings

Common questions
Is a party wall agreement cheaper if my neighbour consents?
Yes. Written consent means no award is needed, so the cost is usually just serving the notices.
