Recently completed the wiring of a new build. Building control did an inspection and failed it, because in his opinion two of the four smoke detectors are too close to light fittings. He says they should be a minimum of 1 foot between the light and the smoke. I measered them and it's about 10 inches. He waffled on something about the convection from the heat of the light bulb would stop any smoke reaching the detector! Now yes I could move them, but that would leave a spare hole in the newly decorated ceiling, which of course the owner doesn't want. They are in the location that the owner wants, and as shown on the plans. So my question is, is this a building regulation, if so does anyone have a link to the exact wording of that regulation, or is he just dreaming? Note we are in Scotland, so it would have to be scottish regs, not England / Wales. I know this particular BC officer well, and when he gets the bit between his teeth, he's like a dog with a bone and won't let it drop, unless you can prove with documentation that it IS okay.
