This is hot from me, makes much more sense if your trying to improve the energy efficiency of your home rather than upgrading to a more efficient boiler or similar.

One thing to note, as a plumber I've always been taught the optimum thickness of insulation is 4", anything more wont give you much more improvement.
Just posted same so I will spam mine.

Would like to add

270mm IS the standard you should install.

NOTE. I personally would go to B&Q and before purchasing at the price of £5.56 for two I would print the Homebase price and 15% voucher which currently means Homebase price is £2.44 per roll and ask for a pricematch which will give you a further 10% discount. Space Blanket is small rolls so should fit through any loft hatch.


get 100mm for the rafters and 170mm to cross lay with the following option:

Use N Power/Build Centre (don't have to be a customer) deal for 2 for 1 Rockwool insulation which can be picked up or delivered free by Build Center. This works out as a slightly better deal. Think this is the option I will be doing.
This should have received more heat than it has. Unlucky.
Heat added from me.
