Building Survey Fee Calculator 2025/26

A HomeBuyer Report (RICS Level 2) is a standardised format survey suitable for conventional homes in reasonable condition built after 1900. It uses a traffic-light rating system (1-3) for each element and provides a market valuation. A Building Survey (RICS Level 3) is a bespoke, comprehensive inspection and written report suitable for older properties, those with extensions or unusual construction, listed buildings, or properties in poor condition. It provides greater detail and usually includes advice on repair costs.

A snagging survey is strongly recommended before legal completion of a new-build home, typically costing £300-£600 for a standard house. A snagging surveyor identifies defects, incomplete finishes, and building regulation compliance issues that the developer must rectify before completion. Defects found after you have legally completed are much harder to get the developer to fix. The NHBC 10-year warranty covers major structural defects but not minor snagging — which is why a pre-completion inspection is valuable.

The lender's mortgage valuation is carried out to protect the lender — it only confirms the property is adequate security for the loan. It is not a survey, does not assess condition in detail, and provides no protection to you as the buyer. The surveyor conducting it has no duty of care to you. You should always commission your own independent survey at the appropriate level for the property type and age. The cost of a survey is a small fraction of the cost of unexpected repair bills after purchase.
