Under the Gas Safety (Installation and Use) Regulations 1998, employers and the self- employed have a duty to ensure that gas installations, appliances and pipe work are maintained in a safe condition by CORGI registered persons, and that appliances are not permitted to be used should the appliance or fittings constitute a danger to any person. Gas systems should be examined at least every 12 months, and records kept on site for inspection.  

For more information on gas safety, see the free leaflet ‘Gas Appliances - get them checked, keep them safe’ (INDG 238).
