Age and type of house
In a timber-frame loft the party line is open above the plasterboard. What has the survey not confirmed about fire stopping in that gap?
Because the party line in this timber-frame loft stands open above the plasterboard, the survey has not confirmed fire stopping in that gap. It has not issued building-regulations approval either. An open line between the roofs is a gap the visit could see, not a tested barrier and not a certificate. What was not confirmed is the stopping and any barrier that should separate one home from the next above the ceiling. The report records the opening. It does not pass the party line.

What is the fuller explanation?
In a timber-frame house the party separation is more than the board in the room below. Where the line runs up into the loft, the closure above that board is part of the separation. Seeing through the gap means the surveyor cannot say stopping is present. A gap is not a fire test, and this visit does not turn it into an approval. The evidence is the opening. The approval is absent because a home survey does not grant one.
Closing the gap needs a specification from someone competent in this sort of frame, with whatever agreement ownership and access require. None of that is done by the sentence in the report. Do not pack the hole with a spare offcut and call it stopped. Do not ignore it because the rooms below looked finished. The loft is where the party line was open, and the loft is where fire stopping is still unconfirmed.
What should you ask your surveyor?
- How wide is the open party line, and what can you see through the gap?
- Was any fire stopping visible above the plasterboard, or none at all?
- Are you confirming a barrier, or recording that the line was open?
What are the typical next steps?
- Record the party line as open, and the fire stopping as not confirmed.
- Do not describe the survey as building-regulations approval of that wall.
- Ask a competent person to specify the stopping before anyone closes the gap.
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 the open gap mean the party wall has failed a fire test?
No. The survey has not tested the gap and has not confirmed fire stopping. An opening above the plasterboard is not an approval and not a test result.
Does the plasterboard in the rooms below close the matter?
No. The opening is above that board. The room lining does not confirm stopping in the loft gap the surveyor could see.
