What is rafter insulation?
Because the whole roof slope, the gables and the party walls now have to be insulated, this costs much more than insulating the floor and saves less heat for the money. It earns its place when you need a warm loft. More about rafter insulation.

Is insulating between the rafters better than the loft floor?
Not for saving energy alone. Insulating the floor heats less space and costs far less. Rafter insulation is the right answer when the loft itself needs to be warm.
Can I use the loft as a bedroom after rafter insulation?
Insulation alone does not make a loft habitable. Fire escape, stairs, floor strength and headroom all come into a conversion, which needs building control.
