Should I call an emergency service or a gas engineer first?

Always call the National Gas Emergency Service on 0800 111 999 first if you suspect a leak. After the immediate danger is assessed, you may be advised to contact a registered gas engineer for further repairs.

Most homes in the UK have a gas shut-off valve near the meter. Turn the valve 90 degrees (a quarter turn) to shut it off. If you’re unsure, ask a gas professional for guidance.

No, avoid using any mobile devices, light switches, or anything that could cause a spark, as this could ignite the gas in the air. Only use your phone once you’re outside and safely away from the property.

Regularly inspect appliances, have them serviced annually by a Gas Safe registered engineer, and check for any visible damage or signs of wear on gas pipes and connections.

Repair time can vary depending on the location and extent of the leak. Minor leaks may be resolved in a few hours, while more complex issues may take longer. The emergency team will provide guidance based on their assessment.

Signs of a gas leak include a strong smell of gas (often like rotten eggs), hissing sounds near a gas line, or physical symptoms like dizziness or nausea. If you notice any of these, evacuate and take immediate action.
