A valuation report estimates the property’s market value, usually for a mortgage lender, and is not a detailed assessment of its condition. A building survey is a more thorough inspection that may identify defects, maintenance needs and potential repair costs, depending on its scope. The survey can help you decide whether to proceed or renegotiate, but it may not uncover every issue and does not replace specialist checks where needed. Costs and report types vary, so confirm what is included with the surveyor and check any lender requirements before arranging either report.
