Hi All, Looking for some opinions/facts please. Our adjoining neighbours property is owned by the local authority who are currently carrying out a series of renovations to there housing stock. Part of these works involve the stripping of the roof and fitting of new tiles. We have a combi boiler which is fitted to the party wall and the flue is vertical up through the loft space and out onto our roof. The councils roofing contractor is insisting that in order to carry out the re-roofing of my neighbours property they need to isolate my boiler each morning for 3 days and then recommission each evening. Not only is it massively inconvenient due to having 2 young children to try and shove out the door in the morning but I don't want a gas engineer to decommission and recommission my boiler over a period of 3 days! My boiler works fine, receives it's annual inspection and service and I am very much of the view that if it ain't broke then don't touch it!! especially when the works have nothing to do with us (our property is privately owned) So in summary, my question is... is this a legal requirement when carrying out works in the vicinity of a flue? They are claiming it is when working within a radius of 1.5m of a flue. I have offered to switch off my boiler at it's control panel when the last adult leaves the house in the morning and proposed that they can use a gas alarm to monitor the flue but apparently that is unacceptable to them as they are also concerned about debris getting into the flue. My view is that this can be mitigated by placing a net (with sufficient sized holes) over the flue during the works and generally just taking care and not going at it like a bull in a china shop Grateful for any thoughts/opinions.
