A level three survey runs to sixty pages and most buyers read the summary. The summary is the least useful part of the document.

Read the caveats first

Every report lists what the surveyor could not inspect. That list tells you where the risk actually sits - under the floor, behind the render, above the ceiling hatch that was screwed shut.

Condition ratings are not costs

A red three means urgent, not expensive. Ask for an order-of-magnitude figure in writing before you take a number to the seller.

When to renegotiate

Structural movement, roof covering at end of life, and any live damp reading are worth reopening the price. Cosmetic items almost never are.
