What is Building Survey?
The most detailed type of residential property inspection, examining a building's structure and condition before purchase.
Full Definition
A building survey (formerly known as a structural survey) is the most thorough form of residential property inspection available in the UK, sitting above the mid-level homebuyer report. Carried out by a qualified surveyor, typically RICS-accredited, it provides a comprehensive assessment of a property's construction, fabric, and condition, including the roof, walls, floors, damp, timber, services, and any defects requiring repair. It is especially recommended for older, larger, unusual, or altered properties, or where a buyer plans significant renovation. The report explains the cause and urgency of problems and often gives repair guidance, helping buyers negotiate the price or budget for works. A building survey does not usually include a formal valuation, which a mortgage lender arranges separately. Costs vary by property size and value and are paid by the buyer. While more expensive than basic surveys, it can prevent costly surprises after completion, making it a valuable safeguard in a major purchase.
