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.

Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.
Fixed written price
The price on the quote is the price you pay. It only changes if you change the job, or if we find something hidden, such as rot, and you agree the change in writing first.
