A glass link joins a barn conversion to a later extension and no papers are in the pack. What approval search has the survey not carried out?
The survey has not carried out a planning or building-regulations approval search for the glass link. The link is there, joining a barn conversion to a later extension, and the pack contains no papers for it. The visit can record the glass, the frame and the junction. It cannot search the council record, and it does not issue a certificate. Approved Document A is structural guidance. It is not a consent this report has produced. No papers in the pack means the approval search is still outstanding, and the survey has not done it.

What is the fuller explanation?
A glass link is a piece of building in its own right, between two older phases. Barn conversions and later extensions often have their own approval histories, and the link can be a further one. The survey looks at what is built. It does not search the planning register or building control. Absence of papers in the pack is a gap in the documents the seller produced. It is not, by itself, a finding that the link was never approved, and the survey does not call the glass unlawful.
Ask the solicitor to search planning and building-regulations records for the barn conversion, the extension, and the glass link as three items, not one. Ask what the seller's replies say about who built the link. Do not ask the survey to stamp a certificate it does not hold. If the structure of the junction needs a closer opinion, that is a separate specialist question. The home survey has not completed the approval search the empty pack leaves open.
What should you ask your surveyor?
- What of the glass link did you inspect, and what could you not see at the junction?
- Have you left planning and building-regulations searches undone?
- Does the report avoid calling the link unlawful in the absence of papers?
What are the typical next steps?
- Treat the missing papers as a search for the solicitor, not a survey result.
- Ask for planning and building-regulations records for the link itself.
- Do not read the report as a certificate for the glass.
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
If the glass looks square and new, has approval been shown?
No. Square new glass shows a recent-looking junction. It does not show a planning permission or a building-regulations certificate. The survey has not carried out that search, and the pack had no papers. Appearance is not approval. A neat junction can still be unapproved.
Can the survey issue the certificate the pack does not contain?
No. The survey does not issue building-regulations certificates. Approved Document A is structural guidance, not a certificate for this glass link. If a certificate exists, it is a council record the solicitor should search for. This report has not produced it, and a careful look at the junction is not that search.
