Here, in Oxford it is also acceptable to fit mains linked smoke detectors to all habitable rooms, this will include any room or cupboard containing either a boiler or water heater, however your glass doors probably won't comply as they are.
Also if your doors are of significant architetral value you may also be exempt however I doubt 1950's doors will count.
If you have no luck with the smoke detector then try doordeals on the internet, but bear in mind you may need to alter some linings as they don't cater totally for some of the odd sized doors found in those properties.
