Gas Emergency Callouts

What Happens When You Call Us

When you call AG Heating for a gas emergency, we prioritise your safety above everything else. Our Gas Safe registered engineer will be dispatched to your property as quickly as possible — day or night, weekday or weekend.

Our emergency callout service covers a wide range of urgent gas and heating situations across London and Hertfordshire. Here’s what we check and action on arrival:

• Locate and isolate any gas leak at source
• Test gas pressure and pipework for faults
• Check and reset boiler lockouts and fault codes
• Carbon monoxide testing and ventilation checks
• Emergency boiler repair or safe shutdown
• Radiator and heating system emergency checks
• Appliance isolation where required for safety
• Gas Safe certificate issued where applicable

Most emergency callouts are attended within the same day. We’ll always give you a clear explanation of what was found and what action was taken.

When Should You Call for a Gas Emergency?

Any situation involving gas or suspected gas issues should be treated as urgent. Do not wait — call AG Heating immediately if you experience any of the following:

🚨 You smell gas in or around your property

🔥 You have no heating or hot water — especially in cold weather

⚠️ Your boiler has locked out or is displaying a fault code

🔔 Your carbon monoxide alarm has been triggered

🛑 You suspect a gas leak from a pipe, meter, or appliance

🕯️ A pilot light keeps going out or won’t stay lit

💨 You have a sudden or unexplained loss of gas supply to your property — call us immediately and we’ll attend as fast as possible, day or night.

Why You Must Never Ignore a Gas Emergency

Gas emergencies are not situations to wait on. Delaying action — or attempting to investigate yourself — can turn a manageable problem into a life-threatening one. The risks of ignoring a suspected gas emergency include:

• Gas explosion risk — even a small leak can ignite with devastating consequences
• Carbon monoxide poisoning — an odourless, colourless gas that can be fatal
• Escalating damage — a small fault left unattended can become a full system failure
• Voided insurance — many policies require prompt action when a hazard is identified
• Legal liability for landlords — failure to act on a reported gas emergency is a criminal offence
• Risk to neighbours — in flats or terraced properties, a leak can spread rapidly
• Delayed engineer response — the longer you wait, the harder the problem becomes to resolve safely

AG Heating’s Gas Safe registered engineers are trained to respond to emergency situations calmly, safely, and effectively. If you’re in any doubt — call us. We’d always rather attend and find nothing than have you face a serious gas incident alone.
