Many complaints can be resolved directly by the firm or professional you are complaining about.
Please contact them to raise your complaint first. Even if the professional works alone, as most surveyors would rather have a chance to put issues right before a formal complaint is made.
All surveyors on sidedoor are RICS regulated and must have a complaints handling procedure (CHP), which they should send you on request.
A firm’s CHP must include details of an independent body like an ombudsman service which can help to resolve disputes.
If you area still unhappy with your RICS Surveyor, RICS has a formal complaints procedure. Please contact them directly: https://www.rics.org/uk/footer/contact-us/complaints/
