The short answer
One competent, genuinely independent agreed surveyor is usually faster, cheaper, less confrontational and easier to manage than two — with no real disadvantage where both owners trust the surveyor’s independence.
Why it matters
A single agreed surveyor removes the repeated back-and-forth between two appointed surveyors, so the process is quicker and the timetable clearer. It feels less adversarial, simplifies communication because both owners know who to contact, and gives one consistent approach to the schedule of condition, access, protective measures and award drafting. Crucially, an agreed surveyor still does not act for either owner: they are appointed by both and must act impartially. It also usually costs less, avoiding duplicated inspections, correspondence and award drafting.
What to do now
- Consider proposing one agreed surveyor wherever both owners are comfortable.
- Reassure the adjoining owner that an agreed surveyor is still impartial and the award still binds both.
- Choose a surveyor with a clear reputation for independence and competence.
Common mistakes
- Assuming two surveyors automatically means more protection — it usually just means more cost.
- Treating an agreed surveyor as the building owner’s surveyor.
- Defaulting to separate appointments without considering one agreed surveyor first.
