Gas boilers – flues in voids

Date published: 10 December 2010

Background

This safety notice provides updated information to that in the safety alert that was issued by the Health and Safety Executive (HSE) on 2 October 2008 following a death earlier that year.

The purpose of the original alert was to raise awareness of the potential dangers from certain types of flues connected to gas-fired central heating installations in some properties (particularly, but not exclusively, a large number of flats and apartments completed since about 2000) that may not have been installed properly, or may have fallen into disrepair.
