Some time this year I'm going to insulate the loft. There's a few cm of really manky looking stuff up there that looks like it's been there for ever.
I had a look at some of the websites that claim to offer discounts and grants but as far as I could gather they mostly seem to have gotchas regarding eligibility, or they require you to change supplier to them as part of the deal.
It's a small 1 bedroom flat and I'm wondering what the most cost-effective/cheapest approach would be. Is it one of those things that the sheds sometimes offer at good prices at certain times of the year? Would I be better going mail order? (I had a look at Screwfix but their choice was very limited).
There seems to be a bewildering choice of materials nowadays and I'm not really sure where to start researching.
