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.
- Cross layer to a total of 270 to 300 mm

Why book with us in Crawley
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
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.
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.
How much does a loft insulation top-up cost in Crawley?
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 Crawley
What do I need to do before you arrive in Crawley?
Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.
How do I pay for work in Crawley?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Do you charge extra to travel to Crawley?
Not normally. Our guide prices include normal travel to Crawley. 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.
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.
