RICS Level 3 Building Surveys represent the most comprehensive property assessment available to property buyers and owners. At Surbiton Surveyors, we conduct hundreds of Level 3 surveys annually across Surrey and South West London, providing detailed analysis that enables informed property decisions. This guide explains everything you need to know about Level 3 Building Surveys.
What is a RICS Level 3 Building Survey?
A RICS Level 3 Building Survey, formerly known as a Full Structural Survey, is the most detailed type of property survey available. It provides a comprehensive assessment of a property's condition, examining all accessible areas and identifying defects, potential problems, and maintenance requirements.
Unlike Level 1 (Condition Report) or Level 2 (HomeBuyer Report) surveys, Level 3 surveys are fully customizable reports that can be tailored to address specific concerns and property types. This flexibility makes them ideal for older, unusual, altered, or high-value properties common throughout Surrey.
