As a qualified gas engineer, I’ve seen first-hand how dangerous neglected gas appliances can become. A gas fire may look harmless sitting in your living room, but if it’s not properly maintained and serviced, it can pose serious risks — including carbon monoxide (CO) poisoning.
Regular servicing isn’t just about efficiency. It’s about safety, protecting your family, and complying with UK regulations.
Why Your Gas Fire Must Be Serviced Annually
In the UK, gas appliances should be checked annually by a Gas Safe registered engineer. Over time, gas fires can develop issues such as:
- Blocked or damaged flues
- Faulty seals
- Worn-out thermocouples
- Cracked heat exchangers
- Debris or soot build-up
- Incomplete combustion
Even a small fault can lead to dangerous emissions or gas leaks.
During a professional service, we:
- Check gas pressure and burner operation
- Inspect and clean the combustion chamber
- Test safety devices
- Check ventilation and flue performance
- Ensure the appliance is burning correctly and safely
- Carry out flue gas analysis where required
A properly serviced gas fire burns cleaner, runs more efficiently, and lasts longer — saving you money while keeping you safe.
The Hidden Danger: Carbon Monoxide (CO)
Carbon monoxide is often called the “silent killer” because:
- It has no smell
- It has no colour
- It has no taste
You cannot detect it without a CO alarm.
CO is produced when gas does not burn properly. Poor ventilation, blocked flues, or faulty appliances are common causes.
Symptoms of Carbon Monoxide Poisoning
Early signs are often mistaken for flu or tiredness. Look out for:
- Headaches
- Dizziness
- Nausea
- Shortness of breath
- Confusion
- Chest pain
- Drowsiness
- Loss of consciousness
If symptoms improve when you leave the house but return when inside, this is a major warning sign.
In severe cases, carbon monoxide poisoning can be fatal.
Physical Signs Your Gas Fire May Be Unsafe
Apart from health symptoms, you may notice:
- Yellow or orange lazy flames (instead of crisp blue flames)
- Soot or black staining around the fire
- Pilot light frequently going out
- Excess condensation on windows
- A burning smell
- Unusual noises from the appliance
If you notice any of these signs, turn off the appliance and seek professional help immediately.
Why CO Alarms Are Essential
Every home with a gas appliance should have a working carbon monoxide alarm. In the UK, CO alarms are legally required in rented properties where solid fuel appliances are installed, and it is strongly recommended for all gas appliances.
A CO alarm:
- Detects dangerous levels early
- Sounds before symptoms become severe
- Gives you time to ventilate and exit safely
Install alarms:
- At least 1–3 metres from the gas appliance
- At breathing height (or as per manufacturer instructions)
- Not directly next to boilers or fires
- Away from kitchens and bathrooms
Test them monthly and replace batteries regularly.
Professional Advice From a Gas Engineer
- Never block ventilation grills or air bricks.
- Never attempt DIY repairs on gas appliances.
- Always use a Gas Safe registered engineer.
- Have appliances serviced annually — even if they “seem fine.”
- Replace old or outdated gas fires.
- Install CO alarms on every level of your home.
- If your CO alarm activates:
- Turn off appliances immediately
- Open windows and doors
- Leave the property
- Call a professional
Gas safety is not something to delay. A simple annual service can prevent life-threatening situations.
Final Thoughts
Your gas fire provides comfort and warmth — but only when it’s properly maintained. Servicing and CO protection are small investments compared to the cost of serious harm.
