    I have discovered that a Care Home that have some responsibility for has Zero insulation in some of its roof space. As any savings in energy go straight to the bottom line we are keen to insulate but I have just been quoted a price of £10 per sq m for 150mm of Isover Spacesaver (laid in the space). This is a rip off but does anyone have experience of commercial insulation jobs and if so what is the going rate?

    Remember that your contractor cannot (or at least should not) get the '3 for 1'-type offers that householders can.

    I realise that but I can still buy the stuff for £3.70 per sq m. I just don't think laying loft insulation is worth £6.30 per sq m.

    Don't forget about the wiring, this may need to be upgraded/derated.

    Thanks Steamy; there is already a provisional sum for that! Another £1,200 to lift the wires.

    150mm is less than recommended these days. Double that?

    You are correct. I misread the quote as they were putting on 100 and then 150 at right angles. Not such a bad price after all.
