More seriously went to a job yesterday where a boiler wasn't working , flue disappeared into wall and then appeared with a vertical flue above roof. The boiler worked with casing off and didn't work with casing on. A check of air intake showed massive build up CO2 and CO with casing on. This had been checked by a firm specialising in LGSCs the day before who had declared a heat exchanger fault and carried out no risk assessment as flue in void. It would have been at Risk if functioning properly as no CO alarm fitted when I arrived. If as I suspect the flue has come apart in the wall this could have killed the tenant.

Boiler was capped off as ID and labelled by me. Riddor report completed.

Incidentally the boiler was fitted 4 months previously by Polish fitters (no racial slur intended just what the land-lady told me). When I asked for their name and contact number they had conveniently gone back to Poland and were apparently uncontactable.

The land-lady didn't wish to supply me the name of the LGSC company either.

Somehow the message isn't getting across chaps.
