The silent killer in 75% of English Homes


Is your home one of the 75% at risk from the silent killer of Carbon Monoxide poisoning?


The publication of the English Housing Survey, in March 2017, shows that only a quarter (28%) of homes have a carbon monoxide alarm installed. This has prompted Paul Merritt, Managing Director of BTU Installation & Maintenance, one of Surrey, London and the South East’s most established heating companies, to highlight the risk posed for families and dwellings without a carbon monoxide alarm. He is calling on all homes without an alarm to install one urgently. To help people understand the importance of carbon monoxide awareness, BTU has created a downloadable information sheet ‘CO Safety Matters’. It will be distributed via the BTU website and social media.

‘We already know that householders are mindful of the safety of their families,’ says Mr Merritt, ‘as according the English House Survey, 89% of homes have fire alarms installed. But, with the most recently published survey reporting that only 28% of homes have a carbon monoxide alarm – it shows that homeowners are running significant risks.’

‘And to underpin the importance of having a CO alarm, RoSPA (Royal Society for the Prevention of Accidents) reports that there are 40 deaths and 200 hospitalisations related to CO poisoning each year in England & Wales. Recent figures from the Department of Health indicate that there are 4,000 attendances at accident and emergency departments for treatment for CO poisoning each year in England - which can often lead to lasting neurological damage. The groups most at risk are children under 14 and the over 65’s. So, we all really need to think about this.’

‘Carbon monoxide is a silent killer, it is colourless and odourless and the symptoms are not always easy to pick up until it is too late. Carbon Monoxide gas is produced when a gas appliance has been incorrectly fitted, badly repaired or poorly maintained. It can also occur if flues, chimneys or vents are blocked. So having an alarm can give great peace of mind. But, you shouldn’t just depend on the alarm for your safety and the safety of your family,’ he continues. ‘Keeping your boiler serviced on an annual basis is critical both for safety and for the efficiency of your boiler. So not getting your boiler serviced annually is really a false economy. An inefficient boiler can cost up to £300 extra to run each year and if not serviced, it will deteriorate more quickly and need replacement sooner – as well as putting your family at risk!’

‘Another safety factor is the risk run by homeowners not checking that the engineer they book to fix, fit or service their boiler or appliance is fully accredited by Gas Safe Registered HETAS and OFTEC.‘

‘At BTU we wholeheartedly encourage everyone to get a carbon monoxide alarm installed the next time they are getting their heating system or appliances serviced. A good quality alarm shouldn’t cost more than a few quid – average costs are £25.00 (including fitting and commissioning during a regular service). That’s not a high price to pay for your family’s safety. Plus, for extra security, don’t forget to check the credentials of the company you use, make sure that they are HETAS, OFTEC and Gas Safe Registered.’ Mr Merritt concludes.

A standard gas boiler service from one of BTU Installation & Maintenance Gas Safe Register accredited engineers costs from £90.00 (this includes VAT and there are no extra costs).   Learn more about our charges.
