What is different about insulating a flat's loft?

In most leasehold flats the loft belongs to the freeholder, so the managing agent or freeholder must agree to the work. We can quote for a single flat or the whole block, and work to the managing agent's access and insurance requirements. More about loft insulation for a flat.

  • Single-flat or whole-block quotes
  • Photos and a completion note for the managing agent or factor
  • Fire compartment walls left intact

Dust sheets on the route in and every bit of packaging taken away.

Tank and pipes protected

Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.

Boarding done properly
