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 finished depth sits at 270 mm or more, the depth the Energy Saving Trust recommends. More about loft insulation.
- Waste packaging removed
- Eaves kept clear, with ventilation trays where air could be blocked
- Mineral wool to 270 to 300 mm across the whole loft floor

Plain-English advice

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 Blackburn
Do you take on jobs outside Blackburn?
Yes. We also work in Darwen and Accrington and elsewhere in Lancashire.
How soon can you visit a home in Blackburn?
We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.
Will I get a written quote for work in Blackburn?
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.
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.
