Common questions from London property owners, investors and occupiers about our RICS Level 3 Building Survey service, answered by Botley Byrne's chartered surveyors.
What is a RICS Level 3 Building Survey?
A RICS Level 3 Building Survey (formerly the Full Structural Survey) is the most comprehensive of the three RICS Home Survey levels. It analyses visible defects in depth, explains their likely causes and implications, and gives full guidance on repair priorities and budget costs. Botley Byrne prepare Level 3 Building Surveys across London and the UK.
Who is a Level 3 Building Survey suitable for?
A Level 3 Building Survey is recommended for older, listed, timber-framed, or non-standard properties, and homes that have been significantly altered, extended, or are in poor or unknown condition. It is the right choice whenever you need a deeper understanding of a property before you commit.
How much does a Level 3 Building Survey cost in London and the UK?
Fees depend on the size, age, and complexity of the property. As the most detailed RICS survey level, a Level 3 Building Survey costs more than a Level 1 or Level 2 report, but is a small cost against the value and risk of the property. We provide a fixed, transparent fee up front. Contact us for a tailored quotation; we respond within 24 hours.
What is the difference between a Level 3 Building Survey and a HomeBuyer Report?
A Level 2 HomeBuyer Report is a visual condition assessment suited to conventional homes. A Level 3 Building Survey goes significantly further, analysing defects in greater depth, explaining likely causes and consequences, and giving fuller guidance on repair options and costs, essential for older or complex properties.
Does a Level 3 Building Survey include a valuation?
Not as standard, but a market valuation can be added to your Level 3 Building Survey on request, for a combined report that satisfies both your own due diligence and your mortgage lender's requirements.
Are your Level 3 surveys RICS-regulated?
Yes. Our Level 3 Building Surveys are prepared by RICS-chartered surveyors within a RICS-regulated firm, to the RICS Home Survey Standard, and backed by professional indemnity insurance, across London and the UK.
