What is blown loft insulation?
The machine stays outside or on the landing and the hose runs up to the loft. We hold a board or tray at the eaves so the loose fill cannot block the ventilation path. More about blown loft insulation.

Why book with us in Cornwall
Clear contact details
Your quote says who to call with questions before, during and after the work.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.
Downlights made safe
Fire-rated covers or a clear zone around recessed lights.
How much does blown loft insulation cost in Cornwall?
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).
Building regulations in England
In England, a loft insulated across more than half its area should reach a U-value of 0.16 W/m²K. Insulation alone is not usually notified to building control. How the rules work across the UK.
Questions about blown loft insulation in Cornwall
Can you quote for several properties in Cornwall?
Yes. Landlords and agents can send a list of addresses and we will survey them in as few visits as we can.
Which council covers my address in Cornwall?
Councils in Cornwall include Cornwall and Isles of Scilly. Your council matters for building control questions and some funding schemes.
Is blown insulation better than rolls?
It performs about the same for the same depth. It is the faster and neater option in lofts that are awkward to work in, and rolls are better where you want boarding later.
Is it messy?
The hose runs through the house, so we sheet the route and the landing. The fibre stays in the loft.
