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
- Eaves kept clear, with ventilation trays where air could be blocked
- Cables lifted clear of the insulation where possible
Why book with us in St Albans
Boarding done properly
Storage boards go on loft legs, never straight onto the insulation.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
Plain-English advice
We explain what we find in plain English, and say so when nothing needs doing.
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.
How much does loft insulation cost in St Albans?
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).

Questions about loft insulation in St Albans
Do you cover all of AL1?
Yes, we cover the AL1 postcode district and the districts around St Albans.
Can you visit St Albans 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.
Can a landlord in St Albans book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
Can you insulate around downlights?
Recessed downlights need clearance or a fire-rated cover so they do not overheat. We fit covers where needed and leave a clear zone around fittings that cannot be covered.
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.
