    Boiler in bathroom/Carbon Monoxide detector

    Not sure what to do here. I am wiring detectors for someone, boiler is in a small cupboard in the bathroom. Too small to fit the detector as it won’t be 1-3m away & I can’t fit it in the bathroom. What’s best, to fit it outside the bathroom? Stupid place to have a bloody boiler!
