When you’re buying an older, unusual, or larger property or one that’s clearly in need of work, it’s vital to understand exactly what you’re getting into. An RICS Level 3 Home Survey, also known as a Building Survey, provides the most detailed assessment available from an RICS-qualified surveyor.

What Is an RICS Level 3 Survey?

A Level 3 Survey is the most comprehensive type of property survey offered by the Royal Institution of Chartered Surveyors (RICS). It’s a detailed inspection of the property’s structure, condition, and construction, identifying both visible and potential hidden defects.

This survey is ideal for:

Older or listed buildings
Unusual constructions or converted properties
Buildings in poor condition
Properties you plan to renovate or extend

What Does a RICS Level 3 Survey Include?

A Level 3 Home Survey provides a thorough understanding of the property, covering:

A detailed inspection of all accessible areas, including the roof space, floors, and structure.
Diagnosis of defects, their causes, and potential consequences.
Professional advice on repairs, estimated timelines, and likely costs.
Guidance on future maintenance and upkeep.
Photos and detailed commentary to make the findings clear and actionable.

Unlike a Level 2 Survey, a Level 3 goes beyond surface-level observations to help you plan your next steps, whether that’s renegotiating the price, budgeting for repairs, or proceeding confidently with your purchase.
