Gas Leak Detection FAQs

I smell gas, what should I do right now?

Open windows and doors, don’t use electrical switches, and evacuate if needed. Call the UK National Gas Emergency Service on 0800 111 999 immediately, then contact Alfie for an inspection.

How do engineers detect gas leaks?

Using calibrated gas detectors, pressure testing and leak-trace methods to find and resolve leaks safely and systematically.

Is it safe to stay at home during a suspected leak?

No. Follow emergency guidance, ventilate the area and wait outside until advised it’s safe to return.

Yes. Engineers can inspect boilers, cookers and pipework and provide safety reports after repair.
