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 finished depth sits at 270 mm or more, the depth the Energy Saving Trust recommends. More about loft insulation.

- Waste packaging removed

Why book with us in Finchley
Plain-English advice
We explain what we find in plain English, and say so when nothing needs doing.
Downlights made safe
Fire-rated covers or a clear zone around recessed lights.
Boarding done properly
Storage boards go on loft legs, never straight onto the insulation.
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.

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 Finchley
Do you cover all of N3?
Yes, we cover the N3 postcode district and the districts around Finchley.
What do I need to do before you arrive in Finchley?
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.
Do you take on jobs outside Finchley?
Yes. We also work in Cricklewood and Kilburn and elsewhere in Greater London.
Does loft insulation need building control approval?
On its own it usually does not, but the work still has to meet the energy standard. The rules differ across England, Wales, Scotland and Northern Ireland, so we confirm the position for your address on the quote.
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.
