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.
- Waste packaging removed
- Area under the cold water tank left clear so it cannot freeze

Why book with us in Whitstable
Plain-English advice
We explain what we find in plain English, and say so when nothing needs doing.
Boarding done properly
Storage boards go on loft legs, never straight onto the insulation.
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 loft insulation cost in Whitstable?
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 loft insulation in Whitstable
Do you charge extra to travel to Whitstable?
Not normally. Our guide prices include normal travel to Whitstable. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Can a landlord in Whitstable book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
Will I get a written quote for work in Whitstable?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
How deep should loft insulation be?
The Energy Saving Trust recommends at least 270 mm of mineral wool, and that is the depth we install as standard. Building regulations also set an energy standard for the roof when a loft is insulated. It differs between England, Wales, Scotland and Northern Ireland, so we confirm the target for your address on the quote.
Does loft insulation need building control approval?
On its own it usually does not, but the work still has to meet the energy standard. The rules differ across England, Wales, Scotland and Northern Ireland, so we confirm the position for your address on the quote.
