Gas Flame Supervision Devices

When did the regulations change?

In June 2006, the Institution of Gas Engineers and Managers (IGEM) published IGE/G/5.  This document provides guidance on the design, installation, operation and maintenance of gas supplies to and in any building containing a number of individual dwellings for domestic purposes only. 

What do the regulations say?

All new installations of flueless gas appliances installed in multi-dwelling buildings need to incorporate a flame supervision device (FSD) on all burners, and comply with the guidance (IGE/G/5). 

What is a Flame Supervision Device? 

A flame supervision device (FSD) will cut off the gas supply if it detects that the flame is extinguished.

Where do the Regulations apply?

Please note:  This list is not exhaustive and is provided for guidance only


  • Multi-storey blocks of flats
  • Single storey maisonettes
  • Other buildings which have been subdivided into domestic dwellings
  • Buildings containing or served by one primary meter
  • Buildings containing or served by more than one secondary meter used for billing purposes
  • Buildings containing or served by one primary meter, but with more than one AECV


  • Detached, semi-detached or terraced houses or bungalows comprising of a single dwelling predominantly occupied by a single family
  • Industrial/ commercial buildings not containing a domestic dwelling

When did the regulations come into effect?

The regulation came in to effect on 1st June 2008

The original implementation date was 1/1/08.  This was changed to 1/6/11 to allow manufacturer to provide suitable numbers of appliances.

Second-hand and previously used appliances

The regulations do not cover the installation of second-hand and previously used appliances. 

“Not to current Standard”

Any new flueless appliance not having FSD protection on all burners in a multi-dwelling building, may be classified as “Not to current Standard” (NCS) in accordance with the procedure given in the current Gas Industry Unsafe Situations Procedure (GIUSP).  A registered installer who carries out such an installation will required to bring the installation up to standard to retain their GasSafe registration.
