I am not sure on the regulations for you Lucadobe however, try your local builders merchants as they sell insulation day in day out...
Unfortunately All the work I do I stand on!!

edit:
just found this on the web...
Building regulations require loft insulation to 0.25W/m²K (a depth of 150mm) and to 0.2W/m²K (depth of 200mm) in less energy efficient buildings. The latter is the economic depth that should be applied to all existing buildings today. This can be achieved by topping-up the existing insulation.
hope this helps!

Hi I spoke to one of the engineers on our site today. he recommends a product called Tri-Iso which i am led to believe is only 4" thick and is compliant with the latest building regs.... this also means that you will not have to extend the rafters to suit a 10" covering....
Tri -iso is available at Buildercentres across the UK.
