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.
- Tank jacket and pipe lagging in the loft
- Eaves kept clear, with ventilation trays where air could be blocked
- Area under the cold water tank left clear so it cannot freeze
Why book with us in Daventry
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.
Boarding done properly
Storage boards go on loft legs, never straight onto the insulation.
Tidy work
Dust sheets on the route in and every bit of packaging taken away.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
How much does loft insulation cost in Daventry?
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

Questions about loft insulation in Daventry
Do you cover all of NN11?
Yes, we cover the NN11 postcode district and the districts around Daventry.
How soon can you visit a home in Daventry?
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.
Is loft work in Daventry 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.
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.
Will loft insulation make my loft colder?
Yes, and that is expected. The insulation keeps the heat in the rooms below, so the loft above runs closer to the outdoor temperature. That is why pipes and the tank are lagged as part of the job.
