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.
