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.
- Area under the cold water tank left clear so it cannot freeze
- Tank jacket and pipe lagging in the loft
- Eaves kept clear, with ventilation trays where air could be blocked
Why book with us in Dorset
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.
Tidy work
Dust sheets on the route in and every bit of packaging taken away.
Boarding done properly
Storage boards go on loft legs, never straight onto the insulation.
Clear contact details
Your quote says who to call with questions before, during and after the work.
How much does loft insulation cost in Dorset?
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). The Energy Saving Trust puts a typical professionally installed loft at about £750 from bare joists, or £600 to top up from 120 mm.
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 loft insulation in Dorset
Are your prices the same across Dorset?
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.
Can you quote for several properties in Dorset?
Yes. Landlords and agents can send a list of addresses and we will survey them in as few visits as we can.
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.
