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 Slough
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.
Tidy work
Dust sheets on the route in and every bit of packaging taken away.
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.
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 Slough?
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 Slough
Do you take on jobs outside Slough?
Yes. We also work in Windsor and Maidenhead and elsewhere in Berkshire.
Do you cover all of SL1?
Yes, we cover the SL1 postcode district and the districts around Slough.
Do you charge extra to travel to Slough?
Not normally. Our guide prices include normal travel to Slough. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Which way should the top-up layer run?
Across the joists, at right angles to the first layer. That covers the tops of the joists, which otherwise let heat escape along the timber.
Is it worth topping up 100 mm of loft insulation?
Often, if the existing layer is in good condition and you also want a warmer house or a better EPC. On bill savings alone, a top-up from about 100 mm takes decades to pay back, so the case is strongest when it is done alongside other loft work.
