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.

Questions about loft insulation in Cobham
Do you take on jobs outside Cobham?
Yes. We also work in Esher and Weybridge and elsewhere in Surrey.
Is loft work in Cobham different from anywhere else?
The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.
How do I pay for work in Cobham?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
What do I need to do before you arrive in Cobham?
Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.
