Gas Safe engineer testing gas controls at a boiler

Once the emergency service has capped the supply, we can trace the leak, repair the pipework or appliance, and test the whole installation so you can turn the gas back on safely.

When to call us

  • The gas emergency service has capped your meter or an appliance
  • A faint smell of gas near the boiler, hob or meter
  • A failed tightness test during a gas safety check
  • A hob or fire with a yellow, lazy flame
  • Headaches or drowsiness that ease when you leave the house (possible carbon monoxide: get out and call 0800 111 999)

What’s included

  • Gas tightness test across the installation
  • Leak tracing on pipework, joints, valves and appliances
  • Repair or replacement of faulty pipework and fittings
  • Re-test and safe reconnection of appliances
  • Advice on carbon monoxide alarms

Emergency first, repair second

The National Gas Emergency Service is the right first call for a live smell of gas: it is free and runs 24 hours a day. Their engineer will make it safe but will not usually carry out repairs. That is where we come in. Leak repair is one of the topics customers most often mention in our Google reviews.
