National Grid operates the 24-hour free-phone national gas emergency service. If you are at all concerned about a gas leak, you should call National Grid on 0800 111 999. Please do not contact BES Commercial Gas, directly.

The National Grid call will not cost you anything. It is operated 24 hours a day, 365 days a year. All calls are recorded and may be monitored.

You will be put through to a trained operator, who will log all important details, which will then be dispatched to an engineer. It is important that you give accurate information, so that National Grid can offer the right gas safety advice.

National Grid aims to attend all uncontrolled escapes within one hour, and all controlled gas escapes within two hours. A controlled gas escape is where the person reporting it has confirmed that the gas emergency control valve, serving the premises, has been turned off and the smell of gas has gone.

National Grid engineers will ensure the premises will be ‘made safe’ when called to a suspected gas escape. However the terms of its licence does not cover repairs to appliances or installation pipe-work, which cannot be completed within 30 minutes.

The information given above applies regardless of who your gas supplier is.


1. Do not use any gas appliances that you think may have a fault.
2. Ensure that all gas appliances are serviced at least once a year by a registered Gas Safe Registered Engineer: www.gassaferegister.co.uk
3. Ensure that all ventilation grilles and outside flues are never covered or blocked.
4. Fit a Carbon Monoxide Detector.
5. Be aware of the position of your gas meter and mains valve.
6. Ensure that the National Grid Emergency Line number is in a visible place. BES Commercial Gas produce free stickers for this purpose.


If any of your gas appliances are faulty they may produce Carbon Monoxide. This is a dangerous by-product of natural gas and is colourless and odourless.

Gas flames should be blue

If your appliances are burning orange or yellow there could be Carbon Monoxide present. If in doubt you should have the appliances checked by a Gas Safe Registered Engineer: www.gassaferegister.co.uk
