Have we any Gas Safe experts on this forum who can help me with a query I have had. Who is competent to inspect Gas Flues...........? The setting is that construction work is taking place on a series of properties and our building firm has been asked to inspect the flue system at the end of each day to ensure it is not damaged as the residents shall remain in the property during works. Previously we had used a gas safe engineer to inspect and certify on completion of the works but have now been asked to do daily inspections as well as this final day inspection. The question is do the daily inspections need to be by a gas safe engineer or could an experienced project manager do this for the dailly checks prior to the gas safe engineer signing off on completion?

IMO the flue of a gas central heating system is the most important part of the system because if it goes wrong people have been known to die. Therefore any person checking such a part of an installation needs to be GasSafe competent.

I think people are over egging the risks. Most boilers are room sealed and carbon monoxide will not seep into the building via the actual boiler. The flue will have to be damaged or blocked with a path for the gas to enter the building. Providing the gas flues are not modified, worked on, damaged, enclosed, blocked or affected by the works then I believe it is appropriate for a site manager to carry out daily end of shift checks and only call in a gas register engineer if there are any issues. The hazards associated with gas flues should have been tackled in a risk and method statement and tool box talks. The end of shift checks should be the last and not the premier control. The site manger should receive some advice/training from a gas register engineer.
