Beware ‘the silent killer’. Why we’re warning about carbon monoxide safety.
Carbon monoxide, the silent killer, is a cause of growing concern among fire safety experts.
By Victoria Wan. Post 1 in our Navigating Energy Challenges series.
A recent survey (1) has highlighted large gaps in knowledge about carbon monoxide safety and the need for much greater awareness.
Silent threat
Carbon monoxide (CO) is a colourless, odourless and tasteless gas that can be deadly.
Alarmingly, 40% of UK residents are unaware of CO poisoning symptoms. FInd out more here. 27% either lack or are unsure if they have a CO alarm at home (1).
This is worrying because:
- An average of 53 people die annually in the UK from accidental CO exposure, with 30% of these deaths occurring at home (2).
- Deaths from accidental CO exposure rose by 39% from 2022 to 2023 (2).
- CO emergency calls in London increased by 37% in 2024 (3).
The statistics make it likely many more households are at risk from carbon monoxide poisoning.
Highlighting CO safety
At Citizens Advice Epsom and Ewell our chief concern is the wellbeing and safety of the people we help. Our Energy Advice Service actively supports clients with a range of energy issues including CO safety.
During energy appointments, we provide crucial information on the dangers and importance of having functioning CO alarms.
If you are worried about CO or any of your energy needs, we can help. Contact us for a FREE appointment
Several clients were unaware of the need for regular alarm testing or did not have alarms installed at all. We assist them by ordering free alarm packs and offer guidance on how to maintain these devices. In January 2025, we helped two clients order alarms for the first time.
Tips for CO Safety
- Have coal, oil and gas appliances checked annually by a professional.
- Ensure proper ventilation for appliances and keep air vents clear.
- Never use a BBQ or portable heater indoors without ventilation.
- Install an audible CO alarm and follow the manufacturer’s instructions.
- Test your alarm regularly and replace batteries or the alarm as needed.
If you suspect CO in your property or if the alarm sounds, open all doors and windows, move outside into fresh air and call the National Gas Emergency Number immediately on 0800 111 999.
More tips for CO Safety. By taking these precautions and staying informed, we can work together to ensure a safer community for all.
