Best place for loft insulation

dllive

Hi,
Im getting underfloor heating in my cottage and want to add new insulation in loft. Some questions:

1) Wheres the cheapest place for loft insulation?
2) Is it 300mm for building regs?
3) I think the insulation thats in there has been there for about 40 years. Should I replace it or just add new stuff over the top of it?
4) Does anyone know any grant scheme in the South West for this (that isnt means-tested)?

Thanks

Hi,

1) Wheres the cheapest place for loft insulation? How would any of us know without doing the research you could do? Prices change all the time; possibly best in summer, but then deals often happen when stuff can be shifted in bulk. Do you ever haggle? I do!
2) Is it 300mm for building regs? Building regs are irrelevant in the sense that you can have what you like. Free schemes will bring you up to building regs.....which might change again next month, next year, whenever.
3) I think the insulation thats in there has been there for about 40 years. Should I replace it or just add new stuff over the top of it? Unless it's deteriorated badly, there's no point in removing and it's a filthy, unpleasant job. Where would you put it? The council won't want it and will quite probably charge you builders' waste costs on it.
4) Does anyone know any grant scheme in the South West for this (that isnt means-tested)?

If you are thinking of doing any re-wiring in the loft, it's best done before the insulation goes in.

Removing the existing insulation is going to be a horrible filthy job, so leave it where it is and put an extra layer on top.
