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 Dartford

Is loft work in Dartford 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.

Can a landlord in Dartford book work for a tenanted house?

Yes. We can arrange access with the tenant directly and send you photos once the work is finished.

Will I get a written quote for work in Dartford?

Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

What do I need to do before you arrive in Dartford?

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.
