The Detail

Not The Same Alarm
As Fire Detection

Carbon monoxide forms whenever a fuel doesn't burn completely, whether that's gas, oil, wood, coal or petrol. A faulty boiler, a blocked flue, a poorly ventilated wood burner or a badly maintained gas fire can all release it into a room. You can't see it, smell it or taste it. By the time you feel unwell, it's already doing damage, so a CO alarm is the only reliable early warning you'll get.

Fitting a CO alarm isn't the same job as fitting a smoke alarm. Smoke alarms watch for particles rising from a fire, so they go on the ceiling. CO alarms watch for gas building up around one specific appliance, so they're sited near it: at a set height and distance from the source, following that model's manufacturer instructions. Get the position wrong and you either get false alarms or no warning when it actually matters.

We fit CO alarms alongside boilers, gas fires, wood burners, multi-fuel stoves, cookers, and in integral garages where a vehicle's kept. Both battery-powered and mains-wired options are available. If your property has more than one fuel-burning appliance, we'll fit and position a separate alarm for each one — one detector can't reliably cover a whole house on its own.

Know The Warning Signs

CO Poisoning Symptoms
Are Easy To Miss

CO poisoning symptoms mimic a virus or plain tiredness. That overlap is exactly what makes carbon monoxide dangerous. Watch for:

  • Headaches, dizziness or nausea indoors
  • Symptoms that ease once you leave the house
  • Yellow or orange gas flames, not blue
  • Sooty staining around an appliance or flue
  • Increased condensation on nearby windows
  • Pilot lights that repeatedly go out

While You Wait For Us

Alarm going off? Turn off the suspected appliance if it's safe to reach, open the windows and doors, and get everyone, pets included, outside into fresh air straight away.

Don't go back inside to investigate, and don't touch light switches or use a naked flame near the property until it's been ventilated and checked. The appliance itself is off-limits too: that's work for a Gas Safe registered engineer, not something to inspect yourself.

Anyone showing symptoms of CO poisoning should call 999. If it's a suspected gas leak or appliance fault rather than a medical emergency, ring the National Gas Emergency Service on 0800 111 999 instead. Either way, stay out until you've been told it's safe to go back in.

FAQs Made Simple

FIND YOUR ANSWERS
Do I need a CO alarm if I don't have a gas boiler?

Wood burners, multi-fuel stoves, oil boilers, even an integral garage with a car parked in it: all of these produce carbon monoxide too. Burning any fuel in the home means you need an alarm. It's not just a gas-appliance issue.

Where exactly should a CO alarm be positioned?

Close to the appliance it's protecting, at the distance and height set out in that alarm's manufacturer instructions. Get it too close and normal appliance operation can set off false trips; too far away and it won't catch a leak early enough. We handle that positioning for the appliance and the room.

Can one CO alarm cover my whole house?

Not reliably, no. Carbon monoxide doesn't spread evenly through a property, so a single detector in the hallway won't necessarily catch a leak in a bedroom two rooms away. Each fuel-burning appliance, and any room you sleep in near one, typically needs its own alarm.

Am I legally required to have a CO alarm as a landlord?

If the property has a fuel-burning appliance (a wood burner or gas fire, say), then in most cases the answer is yes. Exactly where the alarm needs to sit depends on the appliance and the tenancy, so we'll confirm what applies to your property before fitting anything.

Why can't I just rely on my smoke alarm?

A smoke alarm's sensor reacts to smoke particles from a fire. It has no way of detecting carbon monoxide, an invisible gas that can build up in a room with no smoke or flame anywhere in sight. You need both alarms fitted, not one swapped for the other.
