Thanks for that, it's a real pain to get off as its screwed to walls and they have rusted so whave to pull them out leaving holes on the plaster. Shouldn't be an issue though as whoever did the conversion didnt seem to care about the attic. Big holes everywhere allready and there are all sorts of wires just propped up with bits of wood. I reckon i can maybe salvage roughly 10kg of it how much does it go for?
