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 dry, even and not contaminated, we keep it and lay the top-up across it at right angles. More about a loft insulation top-up.

Why book with us in Windsor
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.
Downlights made safe
Fire-rated covers or a clear zone around recessed lights.
No pressure selling
You get everything in writing and decide in your own time.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
How much does a loft insulation top-up cost in Windsor?
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
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 Windsor
Do you cover all of SL4?
Yes, we cover the SL4 postcode district and the districts around Windsor.
Can you visit Windsor outside working hours?
Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.
Will I get a written quote for work in Windsor?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
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.
