What is sheep's wool or natural loft insulation?
Sheep's wool and wood fibre are vapour-open and can take up and release moisture. The trade-off is cost: natural materials usually cost two to three times as much as mineral wool for the same performance. More about sheep's wool or natural loft insulation.

Why book with us in Cornwall
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.
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.
No pressure selling
You get everything in writing and decide in your own time.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
How much does sheep's wool or natural 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 sheep's wool or natural loft insulation in Cornwall
Are your prices the same across Cornwall?
Yes. Our guide prices are the same everywhere we work, and they include normal travel. Your fixed price depends on your loft, not your postcode.
Do you cover the whole of Cornwall?
Yes. We cover every town and village in Cornwall, including Redruth, Falmouth and St Austell.
Is sheep's wool insulation worth the extra cost?
In an older breathable house, or if you care about the material, often yes. In a modern semi with plasterboard ceilings the extra cost buys little performance.
How deep does natural insulation need to be?
It depends on the product's thermal conductivity. Some need slightly more depth than mineral wool to reach the same U-value, which we allow for on the quote.
