1To have your loft insulated to a total thickness of 270mm, if you are over 70, or on certain government benefits, don’t live in a mansion and wish to take advantage of the grants, at the time of writing…
2To have it insulated under the grant scheme, even if you don’t qualify for a full grant, depending on the size of your property, you will pay between £100 – £200.
£150
3If you are above applying for a grant (or like me, you are totally bewildered as to how everyone else in the country qualifies except YOU) and decide to go it alone, assuming your loft is clear and your house is “normal size”. To add another 200 mm of insulation to your existing 100mm, will take 2 blokes half a day including buying the stuff.
£300


“Labour” at £175 a day (tradesman) £100 (labourer), includes incidental fixings etc. and tipping charges. “Materials” if mentioned, are larger things (a boiler) and stuff only you can choose (tiles etc).  Also VAT must be added all round.

Information Sheet on fitting Loft Insulation


No insulation job anywhere in the house has such an immediate and obvious effect as insulating the loft. Suddenly you are warm!

AND you can’t put “too much” up there. Today’s requirement for a brand new house with fibreglass rolls, is the silly thickness of 270mm. That is usually achieved by laying 100mm between the joists and 200 mm on top of the joists. Why, because no one sells 170mm thick stuff!

Ten years ago it was 200mm. In ten years time some new stuff will have been invented that leaves even the best stuff we have now (which you will be pleased to know, isn’t fibreglass) completely behind AND we will have to put 270mm of that down. (Or 327.5 mm if we leave it to the “the government”).


There’s a problem of course with putting a lot down, you can’t see the joist tops anymore, so walking around up there is even more “hairy” than ever. Plus, if you lay down boards to walk or store stuff on, the “200mm” of insulation laid above the joists, squashes down. If you squash this down to 50mm say, you that becomes it’s useful thickness…50mm


It’s the trapped air, not the fibreglass, which does the insulating!


If you want to board out, make sure there is insulation level with the tops of the joists, then deck out with proprietary, insulated boards (Celotex/Kingspan).

There are grants. (at the time of writing). Not just for your granny, for everyone but they won’t last forever. “Google” your way to a saving. There are plenty of companies, more than happy to “guide you through the process” then come and lay the insulation for you. All you have to do is clear the loft for them and you know, …..that might just be a good thing!
