Loft insulation in other towns
Building regulations in England
Insulating a loft is treated as renovating a thermal element when more than half of the ceiling area is insulated. Approved Document L sets a target U-value of 0.16 W/m²K, which is around 250 to 300 mm of mineral wool. Loft insulation on its own usually does not need a building notice, but it still has to meet that standard. Rafter insulation that forms part of a loft conversion is notifiable building work.
