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. Shared lofts usually have fire separation between flats that must not be disturbed. More about loft insulation for a flat.

Eaves kept clear

Insulation is held back from the eaves so the loft can still ventilate.

Tank and pipes protected

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

Rented homes
