Gas Safety and Carbon Monoxide
Each year, according to the Health and Safety Executive (HSE), approximately 20 to 30 people
die from carbon monoxide (CO) poisoning associated with gas appliances, a figure that could be
reduced if people understood the risks and took sensible precautions.
Fuel gas is safe, but if appliances are not properly installed and adequately maintained by a
competent Council for Registered Gas Installers (CORGI) registered installer, the gas may not burn
properly meaning CO fumes are released.
In addition to getting appliances checked, it is also important to ensure they are used
correctly. CO is produced when there is not enough air for complete burning of the fuel. Never use
a gas appliance if you think it is not working properly.
Signs to look out for on boilers, fires and cookers include:
- yellow or orange flames (except for fuel-effect fires that display this colour flame),
- soot or stains around the appliance, and
- a pilot light that frequently blows out.
Approved CO detectors are strongly recommended, although these must not be used as a substitute
for regular checks and servicing by a CORGI-registered installer.
You cannot see, smell or taste CO fumes. Symptoms of CO poisoning can include tiredness,
drowsiness, headaches and breathlessness. In the worst situations, CO can kill without warning in
just hours - If you believe CO may be causing you problems seek urgent medical advice.
Research by the University College London commissioned by the HSE highlights the dangers of CO
poisoning in people's homes, coupled with a lack of public awareness of the risks. The early
findings of the research include:
- 23% of homes had one or more defective gas appliance,
- 8% of homes were judged to be at risk of dangerous levels of CO,
- 45% of homes had received no information on the dangers of CO, and
- A higher prevalence of problem appliances was found in the homes of vulnerable people (young,
old, those in receipt of benefits).
The HSE advises:
- The symptoms can be mistaken for influenza, so don’t become an unwitting victim.
- If you are becoming a tenant of rented property, ask your landlord for your gas safety
certificate. He is required by law to show it to you so you know your gas appliances have been
serviced annually.
If you are renting property then by law your landlord must:
- Ensure that gas appliances, flues and associated gas pipe work etc are maintained, in a safe
condition, by a CORGI Registered installer.
- Have an annual safety check carried out, by a CORGI-registered installer, on each gas
appliance that they own in the properties that they let.
- Provide you with a copy of the record before you move in and within 28 days of each
subsequent annual check being performed.
Tenants should:
- Check the record to ensure it is current and, if it indicates any appliance is defective,
check that remedial action has been taken or the appliance has been made safe.
- Remember, it is your responsibility to maintain any gas appliance that you own e.g.:
cooker or mobile heater.
- If you need further advice or have doubts that the record is genuine contact CORGI on 0870
401 2300.
- If a managing agent lets your property, ensure the contract stipulates who is responsible for
carrying out the above checks.
Gas Fitters
- It is unlawful for anyone to carry out gas fitting work, in domestic or commercial premises,
as a business unless they are registered with CORGI. It is also unlawful for anyone to claim that
they are CORGI registered when they are not.
- All genuine gas fitters expect to be asked to produce their CORGI registration ID card before
being invited into your property. The information on the card is also printed in Braille.
- Apart from checking the identification details on the front of the card also check the expiry
date to ensure the fitters registration is still current. On the back of the card check the list
of work categories to ensure the fitter is competent to perform the job you need doing.
