Gas Emergency

If you can smell gas, and think you have a gas leak, turn off your gas at the meter if possible and make yourself safe. You then need to call the National Gas Service Emergency Line on 0800 11 999. 

Here is what you can do to ensure that you stay safe: 

  • Open all doors and windows to let in plenty of air
  • Leave all electrical appliances as they are - do not turn anything on or off 
  • Put out any naked flames and do not smoke, strike a match or do anything that could cause ignition.

Carbon Monoxide 

Carbon Monoxide is a dangerous gas that can be produced by faulty gas appliances or in rooms with poor ventilation. It is odourless and colourless, so we recommend using a Carbon Monoxide Detector in your home.

 We recommend using a detector that makes a sound when it detects the gas, so that it can wake you up if necessary. A detector is a safeguard but not a substitute for proper installation and maintenance of gas appliances.

You should also be aware of the following signs that carbon monoxide may be present:

  • Evidence of soot, stains, or discolouration near gas appliances like boilers, gas fires, or water heaters
  • Poor ventilation – blocked air vents, blocked chimney flues Yellow or orange rather than blue flames in gas appliances
  • Headaches, nausea, dizziness, or flu-like symptoms- if you believe you are experiencing these symptoms seek medical attention immediately

For more information on carbon monoxide poisoning visit the NHS or telephone NHS Direct on 0845 4647. If you think there is a carbon monoxide leak in your home, make yourself safe and call the National Gas Emergency Line on 0800 111 999. 

Electrical Emergency 

Your electricity network operator looks after the safety and security of your electricity supply. If your power goes off, or if you have an electrical emergency, contact your network operator straight away. 

You can either get through to them by calling 105 from anywhere in the country or visit to find out who your local network operator is. 

You can identify your local Distribution Network Operator (DNO) from your supply number. Your supply number should always be found on your electricity bill. Your supply number should always be in the following format:  

Use the bottom left first two numbers e.g. 12 = your local DNO number.
