What is a loft insulation top-up?
Before we quote we measure the existing layer in several places and check its condition. If it is wet, dirty, matted or full of droppings, laying fresh wool on top just buries the problem, so we say so and price removal instead. More about a loft insulation top-up.
- Gaps in the existing layer filled
- Tank jacket and pipe lagging in the loft
- Cross layer to a total of 270 to 300 mm
Why book with us in Dorset
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
No pressure selling
You get everything in writing and decide in your own time.
Clear contact details
Your quote says who to call with questions before, during and after the work.
How much does a loft insulation top-up 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 a loft insulation top-up in Dorset
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.
How do I book a survey in Dorset?
Send the form or call us. We call back to agree a time and confirm it in writing.
Can I still store things in the loft after a top-up?
Not directly on the insulation. A 270 mm layer stands well above the joists, so storage needs raised boarding on loft legs.
Can new insulation go on top of old insulation?
Yes, if the old layer is dry, clean and reasonably even. If it is damp, contaminated or badly compressed we recommend removing it first.
