Carbon monoxide (CO) is a colourless, odourless and poisonous gas that can be given off as a result of the incomplete burning of gas by household appliances.  National Grid operates the National Gas Emergency Number (0800 111 999) across Great Britain, is the largest owner of gas distribution networks in Great Britain and is the Gas Transporter (GT)/Emergency Service Provider (ESP) for the North West, West Midlands, East Midlands, East Anglia and North London Regional areas.  Reports or actual escapes of CO are responded to and made safe at no charge by the relevant Gas Transporter/Emergency Service Provider responsible for the network.  Under the GT/ESP's respective license conditions, the arrangement of work other than making safe is the responsibility of the consumer and/or their gas supplier.  More information on CO can be found on the Gas safe register.

Carbon Monoxide Warning

You may be entitled to a free annual safety check of gas appliances if ALL of the adults in your home are eligible for the Priority Services Register. Contact your registered gas supplier for further details.
