sydthebeat wrote: » there are better options than going through the slates... either create an access in the original house through the blockwork, or create an attic hatch access in the ceiling of the extension. The price quoted seems thats hes essentially charging 50% of the total price as labour... so about €1500 materials and €1500 labour is the 132 sq m the size of the two storeys of the original house? if so 132 / 2 = 66 + 40sq m extension assumed = 106 sqm off attic space youd need 18 rolls to cover that @ approx €30 each incl VAT = €536 (hes quoting €1219) soffit vents shouldnt cost any more than €1 each... so assuming your house is about 7m wide, and installing soffit vents at 300mm c/c means you need about 70 vents.... How did the guy assess how much insulation is in the extension attic already?

I’ve read threads on here about people getting attic insulation 200mm top ups for several hundred euro after grants so I was shocked at this price

I don't know if removing slates is ideal but it is not uncommon. If it is a case of sending a lad into the attic to throw down a few rolls of glass wool then yes it will be a few hundred. Insulation is typically fitted very badly in this country, so it is worth paying attention to detail. id say do it in very cold weather with a thermal camera but no one does that. I have no idea if the price you have quoted is good or not, but it sounds like a more thorough job.
