    I need to put a hole through the external wall for a kitchen extractor and there's already a couple of other holes in the vicinity. I can't find any regs or official guidance for how large a hole you can make and how far they should be from other holes, openings etc. Is anyone here aware of anything?

    Thank you

    If you are just talking about a domestic type fan 100mm Dia there's no regs applicable.

    Not sure what the point of this comment is? Are you suggesting steelwork may be required?

    To be fair there are some massive commercial fans out there, we have one in our domestic garage, sucks the doors shut! But we spray/weld/grind a lot of stuff in there. We wedge a door slightly, open turn on fan, fumes gone in seconds.

    One of the consequences of mixing in a plastic tub, along with Fairy is that you need much less wate
    DON'T DRILL BENEATH STEEL OR LINTEL BEARINGS!
