Should CO alarms be mandatory? Installers have their say

The Government is being urged to make CO alarms mandatory, in a bid to save lives. 
The campaign, spearheaded by Plumb and Parts Center, leading alarm manufacturer Honeywell and the Katie Haines Memorial Trust, says alarms should be required with the installation of any carbon-burning appliance.
According to the Health & Safety Executive (HSE), 40 people die every year from accidental CO poisoning and 4,000 people are treated at A&E Departments with symptoms. But Chief Medical Officer, Dame Sally Davies, says the number of people affected by sub-lethal exposure is likely to be even greater than reported.
So is this a good idea? Installers have been having their say:
