Level 3 Building Survey

The detail behind
your decision.

A thorough building survey for older, altered or less predictable properties, where a condition overview would leave too much unanswered. The report explains what is wrong, why, what it is likely to cost to put right and what to do next.

The essentials

Level 3 Building Survey
at a glance.

Designed for older, altered or higher-risk homes where buyers need detailed, RICS-regulated advice before purchase.

What it is

A detailed building survey that looks closely at construction, visible defects, their likely causes, maintenance priorities and future repair implications.

Who it suits

Older, extended, altered, larger or non-standard properties, and any home where visible condition or risk needs deeper analysis.

What you get

Detailed findings with photographs, condition ratings, repair context, a risk summary and practical next steps for negotiation or planning.

How it compares

More depth than Level 2. Level 3+ adds a drone roof inspection where safe to fly, an estimated repair cost breakdown and a reinstatement cost for insurance.

Is it the right level?

Level 3 is usually right
if the property is…

  • Extended, converted or significantly altered

  • Showing visible signs of age, wear or defects
  • Larger, higher-value or complex

Deeper understanding
