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.

Why book with us in Weymouth
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
Downlights made safe
Fire-rated covers or a clear zone around recessed lights.
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.
How much does loft insulation for a flat cost in Weymouth?
Installing insulation in a home is zero-rated for VAT until 31 March 2027 and 5% after that, under HMRC's rules for energy-saving materials (notice 708/6).
