Specific or General Structural Inspection: Which Report Do You Need?
Compare SSI and GSI scope, fixed prices and the situations each structural inspection is designed to address.
Choose a Specific Structural Inspection (SSI) when you need one defined concern investigated, such as a crack, bowing wall or issue identified in a survey. Choose a General Structural Inspection (GSI) when several concerns need to be considered or you want a broader inspection of the property's main visible structural elements.
Send us the survey wording if you are unsure. We will recommend the narrower service where it properly answers the question; a larger inspection is not automatically better.

| SSI | GSI | |
|---|---|---|
| Best for | One defined structural concern | Several concerns or a broader structural view |
| Examples | One crack, wall, roof area, beam or survey item | Pre-purchase concerns affecting different parts of the property |
| Starting price | £480 including VAT | £585 including VAT |
| Includes | Agreed inspection and focused written report | Main visible structural elements and written report |
Choose an SSI when
- One crack, wall, roof area, beam or other defined concern needs investigating.
- A surveyor has referred one issue for a structural engineer's opinion.
- A lender, solicitor or insurer has asked a specific structural question.
- You need a focused written report rather than a whole-property overview.
Choose a GSI when
- A survey identifies several structural concerns.
- You are buying and want the main visible structural elements considered together.
- Movement or defects appear in different parts of the property.
- One narrowly focused report would not answer the overall question.
How is this different from a RICS survey?
A RICS survey considers the wider condition of a property and may cover matters outside structural engineering. An SSI or GSI addresses an agreed structural scope. A GSI is therefore not a replacement for advice on services, damp, finishes or every non-structural defect.
