If you smell gas, your boiler has failed in cold weather, or you’ve lost all hot water, you need a Gas Safe registered engineer quickly — not a callback in three days. Gas First provides emergency gas engineer cover across East London and Essex, around the clock. We prioritise safety first: making the situation safe, then diagnosing and fixing the fault. If you can smell gas right now, turn off the supply at the meter, open windows, avoid switches and naked flames, and call the National Gas Emergency Service on 0800 111 999, then call us.
What counts as a gas emergency — and when should you call out?
Treat it as an emergency if you smell gas, hear hissing near a gas appliance, see signs of a leak, have no heating or hot water in cold conditions, or your boiler has locked out and won’t restart. Carbon monoxide symptoms — headaches, dizziness, nausea that ease when you leave the house, or a CO alarm sounding — are also emergencies: get fresh air and call for help immediately.

What does an emergency gas engineer actually do when they arrive?

You’ll always know what we’ve found and what happens next.

Can you smell gas right now? Here's exactly what to do.
If you suspect a gas leak: don’t turn anything electrical on or off, don’t use naked flames, open doors and windows, turn the gas off at the meter control valve if you can do so safely, and get everyone out if the smell is strong. The National Gas Emergency line (0800 111 999) is free and open 24 hours. Once the immediate danger is handled, we can repair the underlying fault.
