Safety is paramount. Our most important goals are: to ensure that members of the public are not injured as a direct result of our operations; to deliver a working environment where there are zero work-related injuries and illnesses; to reduce gas leaks on our distribution networks; and to improve the health of our employees so they are fit for work every day.

We use a range of indicators to monitor our performance including: members of the public injured as a direct result of our operations; employee lost time injury frequency rate; kilometres of gas distribution mains replaced in the UK; and employee sickness absence rate. Our key performance indicator is our employee lost time injury frequency rate.

Carbon monoxide

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 carbon monoxide 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 website.
