The combi flue ends under the carport roof. Why should that be described as a flue position, not priced as a repair inside the survey?
Because the combi flue ending under the carport roof is a position to describe, not a repair for the survey to price. The survey can record where the terminal sits, under that roof. It does not design a new route, write a quotation, or certify the flue. Pricing a repair inside the report would invent a figure and a scheme the inspection did not produce. Gas work belongs with a Gas Safe engineer. Ask them to comment on this terminal position. Keep the survey sentence as a description of where the flue ends.

What is the fuller explanation?
A flue position is what the surveyor could see: the terminal, the carport roof above it, and the wall it leaves. Whether that place is acceptable is a judgement for a Gas Safe engineer, not a sum of money written into a home survey. The survey does not price repairs. Describing the position leaves you free to get proper advice. Inventing a repair price would pretend the visit had already chosen the work and costed it, which it has not.
Show a Gas Safe engineer the terminal under the carport and ask them to say what, if anything, should change. Do not remove the flue or box the carport in on a viewing. If you later receive a quotation, keep it beside the survey rather than copying a figure back into the report. The survey's job was to describe the position. The engineer's job is to assess it. Mixing those jobs is how a sighting gets rewritten as a priced repair nobody has specified.
What should you ask your surveyor?
- Where exactly does the flue end: under the roof, at the edge, or against a beam?
- What surrounds the terminal that a Gas Safe engineer should be shown?
- Did you price any alteration, or only describe the position?
What are the typical next steps?
- Keep the survey as a description of the flue position.
- Ask a Gas Safe engineer to assess the terminal under the carport.
- Do not write a repair price into the survey finding.
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 boiler was running, is the flue position acceptable?
No. Running on the day does not assess where the terminal sits under the carport roof. That position still needs a Gas Safe engineer.
Should the survey name a figure for moving the flue?
No. The survey describes the position. It does not price a repair. A quotation, if you need one, comes from the person who would do the work.
