Everyone knows that gas combo boilers leak carbon monoxide but not many realise that anything that is burning is giving off CO. Public misconception is that it is a bi-product of burning gas. 
Since October 2010 it has been mandatory to instal a CO alarm with every wood burner / multi-fuel stove. There is a correct place to fit it.
We always carry detectors on the van and always offer them at a discounted rate with a sweep for those that do not yet have one. Even  if you would like us to visit solely to instal a detector please just call. Everyone should have at least one.

Advice on Carbon Monoxide



Carbon Monoxide the Silent Killer


Carbon Monoxide (CO) is an extremely poisonous gas

that can be present in the fumes from the combustion of

fuel's which aren’t burnt under the correct conditions. Fuels such as gas,

oil, solid mineral fuel and biomass all have the potential to

emit CO. The gas cannot be seen, smelt or tasted making it difficult to detect.


The symptoms of carbon monoxide poisoning


The early symptoms of CO poisoning are usually similar to common ailments such as upset stomach, tiredness and flu.

The common symptoms can include:


bullet32-1 Headaches


 Nausea and/or vomiting

 Dizziness or Collapse

 Chest and/or stomach pains

 Erratic behaviour and/or Visual problems.




If you suspect fumes are escaping from your combustion appliance into your home, or your carbon monoxide alarm goes off.


tick33 If your appliance is automatically fed with fuel, turn the appliance off.


 Open doors and windows to ventilate the building.


 Leave the building immediately and don’t return until your appliance or boiler has extinguished and the air in the room is clear.


If you feel unwell go to your Doctor, call NHS Direct on 0845 4647 or, if it is urgent phone 999 for an ambulance. Tell them you feel your symptoms may be related to carbon monoxide poisoning.


Before you reuse the appliance, have it serviced and the chimney swept by a HETAS registered installer or approved chimney sweep.


Do not use the appliance until you are told it is safe to do so.


Protect yourself from CO



Have your appliance serviced and cleaned regularily by a HETAS registered installer.


Ensure your chimney is kept clear by having it swept at frequent intervals as recommended by HETAS, your sweep, the solid fuel association or your local fire and rescue service (see links page) 


Make sure the installation complies with Building Regulations guidance. The guidance is there to protect you.


Fit an audible CO alarm conforming to BS EN 50291 and positioned in accordance with Building Regulation s Approved Document J requirements. 


CO alarms should be regularly tested and should not be regarded as a substitute for regular maintenance of the appliance and chimney.
