What is loft insulation?
We lay the first layer to the depth of the joists, usually 100 mm, so it fills each bay edge to edge with no gaps. The second layer goes across the joists at right angles, which covers the timber and stops it acting as a cold bridge. More about loft insulation.
- Mineral wool to 270 to 300 mm across the whole loft floor
- Cables lifted clear of the insulation where possible
- Tank jacket and pipe lagging in the loft

Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.
Downlights made safe
Fire-rated covers or a clear zone around recessed lights.
How much does loft insulation cost in Pontypridd?
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).

Questions about loft insulation in Pontypridd
Do you cover all of CF37?
Yes, we cover the CF37 postcode district and the districts around Pontypridd.
Is loft work in Pontypridd different from anywhere else?
The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.
Can a landlord in Pontypridd book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
Do I need to empty my loft first?
The floor needs to be clear for the insulation to go down. If moving things yourself is difficult, tell us at the survey and we can price clearing and putting items back on raised boarding.
How deep should loft insulation be?
The Energy Saving Trust recommends at least 270 mm of mineral wool, and that is the depth we install as standard. Building regulations also set an energy standard for the roof when a loft is insulated. It differs between England, Wales, Scotland and Northern Ireland, so we confirm the target for your address on the quote.
