RAAC

A concrete soffit is stained and the survey will not name the panel. What investigation has the home survey not done?

Not a named panel, and not a RAAC investigation. A stained concrete soffit, which the survey will not name, has not been identified. The home survey has not carried out the investigation and assessment IStructE describes for RAAC panels. Staining is something seen on the surface. It is not a product name. Refusing to name the panel is the honest limit of a visual home survey, not a hint you should upgrade into a diagnosis. What has not been done is the specialist work of establishing whether the panel is RAAC at all.

What is the fuller explanation?

RAAC panels need a deliberate investigation: what the unit is, how it is built, and what condition that implies. A home survey records condition it can see. A stain can come from a leak, from condensation, or from something else, and the surveyor may say they cannot tell. None of those sentences is a laboratory or a specialist identification. Do not fill the blank with the word RAAC because the soffit is concrete and marked. Unnamed means unnamed.

If you need the panel named, that is a further instruction to someone competent to investigate it, with access the home survey may not have had. Until then, quote the survey: concrete soffit, stained, material not named. Do not tell a lender the house contains RAAC, and do not tell them it has been cleared of RAAC. Both claims need the investigation this report has not done. The stain stays a stain. The name stays open.

What should you ask your surveyor?

What did you see on the soffit apart from the stain?
Why have you not named the panel material?
What access would a specialist need that this visit did not have?

What are the typical next steps?

Leave the panel unnamed, as the survey has left it.
Do not call the stain a RAAC finding.
Commission a specialist investigation only if you need the panel identified.

Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.

Also asked about this

Does a stained concrete soffit mean the panel is RAAC?

No. The survey has not named it, and it has not done a RAAC investigation. Stain is not identification of the panel.

Can you insure or declare the soffit as cleared?

No. Clearance would be a result of an investigation. The home survey has not done that work, so the soffit stays unnamed.
