Insulation should be on the floor of the space. The attic should be about the same temperature as the outside. If it is warmer you will get condensation on the inside of the walls and the wood can rot or get mould.
Ensure the attic is vented as well to avoid excess humidity.
We use two types: large bundles that lie between the rafters or, in larger spaces, insulation blown in with a machine. The blown in kind is probably overkill for your mild UK climate.
The blown insulation is standard in Canada, we had minus 40C a few weeks ago.
We can get government grants to offset the cost of insulating, since it reduces energy consumption. Maybe you can get help there? -
I'm not clear - is the loft conversion (middle bit) insulated at roof level, and not in the floor? Does that insulation come down the (presumed) wall with little door in? Is it in the roof and then just stops, so heat from the middle space goes through the storage to the outside, as well as heat from downstairs going up through the storage space to outside?

Loft insulation.
Our house has a loft conversion, but there's storage in the rafters with a little door to stick stuff in there.
However, there's no insulation in that space, which I'd like to address. I'm not sure whether I should be insulating the inside of the roof (i.e. the diagonal rafters above your head when you're in the space), or the floor of space (i.e. the interface between space and the inside of the house). Or both...
Does anyone have any recommendations.
