Hi! I'm doing lots of work - see preious posts! There is no attic insulation in the property we rent out - built 25 years ago. Do I need to get one of these insulation companies out, or can my polish carpenter/handyman friend just lay Kingspan insulation in the attic for me - the rolled stuff. The house is 2 bedroomed and is 860sq feet - so I don't know who much insulation I will need for the attic. What would it roughly cost to get the attic insulated. Is there a grant for this also?
