Emergency Gas Leak Response

What the service covers

A fast, safety-first response focused on isolating danger and restoring safe use where possible.

• Rapid attendance for suspected or confirmed gas leaks
• Isolation of gas supply at the emergency control valve where required
• Gas tightness testing and basic fault-finding to help locate the issue
• Making appliances and pipework safe (disconnecting or capping as needed)
• Ventilation and safety checks in affected areas
• Clear explanation of findings, next steps, and what can and cannot be used
• Repair work where safe and practical to complete during the visit
• Gas Safe compliant working practices and documentation where applicable

When you should call

This service is right for urgent situations, including:

• Smell of gas inside or outside the property
• Hissing sounds near pipework, meter boxes or appliances
• Pilot lights repeatedly going out, sooting, or signs of incomplete combustion
• An appliance has been damaged, moved, or recently installed and you suspect a leak
• You have isolated the gas but need confirmation and a safe route back to normal use

If you believe there is immediate danger, open windows, avoid switches and naked flames, leave the property if needed, and call the National Gas Emergency Service on 0800 111 999.

What happens during the visit

The visit is structured to control risk first, then diagnose.

1. Initial safety assessment: confirm symptoms, check ventilation, and assess immediate hazards.
2. Isolate and test: shut off the supply if required and carry out gas tightness testing.
3. Locate the issue: investigate likely sources such as joints, pipe runs, appliance connections, or meter areas.
4. Make safe: disconnect, cap, or isolate appliances or sections of pipework where necessary.
5. Repair where possible: complete repairs if safe, parts are available, and access allows.

You will be kept informed throughout, with straightforward options and next steps.

After the system is safe

Once risk is controlled, you will receive guidance on:

• Whether gas can be left on, or must remain isolated
• What repairs are required and what can be scheduled next
• Any further checks recommended before full reinstatement
• Preventive steps to reduce repeat issues, such as replacing worn connectors or improving appliance isolation and access
