My only option is to pour something like eps beads from the loft down two stories. I dont think rewiring the whole side of the house is a simple option. Thanks to you all but thats a lot of quite conflicting information. From "Its fine " to "downgrade the wiring to stop it overheating" This doesn't seem to be a cheap or DIY project any more.

So I can ignore this small print?

I have looked into EPS insulation but it says this "Expanded Polystyrene should not come into contact with any PVC cables. This is to avoid plasticizer migration which causes PVC cables to become brittle and fragile. Any PVC cables should be protected within a suitable conduit or with a suitable air gap." I have some electric cables behind the wall which I can only assume are PVC as I have no idea.

Thanks but Id like to do it myself and save money. Im guessing that Blown beads is not DIY?

Hello I have discovered that the previous owners of my house removed the chimneys and covered up the "bungaroosh" walls with plaster board but without any insulation. This goes up two floors to a cold loft on one half of the house. I can get access to about 150cm wide by 10 cm deep gap from the loft. and believe there is a void 3m wide 5m high 10cm deep. 0.1×3×5 = 1.5 meters3 I live in a 19th century mid terrace. My questions are should I try and fill this void from the top with Vermiculite Micafil Loose Fill Insulation? eg https://www.amazon.co.uk/Vermiculite-Micafil-Loose-Insulation-100ltr/dp/B018NVZK7U/ I calculate I would need 15 bags @ £35 = £525! But I have no idea how well it will spread in the void. Is there something better/cheaper? Or should I not bother and just pack the top best I can with rockwool? thanks a lot for any help Joe G
