What decides the cost of insulating your loft
We don’t publish prices because every loft is different. Here’s what makes the difference, so the figure in your quote makes sense.

The size of the loft
Insulation is laid by the square metre, so a bigger floor means more material and more time.
What’s already there
Topping up a sound layer costs less than taking old insulation out and starting again.
The material
Mineral wool is the most affordable. Sheep’s wool and recycled polyester cost more. Your quote can show more than one so you can compare.
Access and extras
A small hatch, a cramped loft or lots of storage to move all add time. Boarding, ladders, vents and clearing are priced separately and listed clearly.
Common questions
Why don’t you show prices?
Because they vary so much from loft to loft that a guide price would mislead more people than it helped. Your quote is free.
Can I see the price for wool and mineral wool side by side?
Yes. Just ask on the form.
Are there hidden extras?
No. Everything is in the written quote before you decide.
