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.

- Loose-fill mineral wool to the agreed depth
- Hatch area finished with a retaining upstand
Why book with us in Dolgellau
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
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.
Plain-English advice
We explain what we find in plain English, and say so when nothing needs doing.
Boarding done properly
Storage boards go on loft legs, never straight onto the insulation.
How much does blown loft insulation cost in Dolgellau?
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 Wales
Wales has its own Approved Document L. Insulation alone is not normally notified, but conversions need building control. How the rules work across the UK.
Questions about blown loft insulation in Dolgellau
Do you cover all of LL40?
Yes, we cover the LL40 postcode district and the districts around Dolgellau.
How soon can you visit a home in Dolgellau?
We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.
What do I need to do before you arrive in Dolgellau?
Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.
Is it messy?
The hose runs through the house, so we sheet the route and the landing. The fibre stays in the loft.
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.
