It isn't actually that expensive to pump in insulation into the walls. Expol underfloor insulation however is a waste of money IMHO, especially as heat rises.

We did the above & it works. The floorboards have dreid out & now creak like hell when you walk around at night. PJ

Edit...Would appreciate a link for wall pumped insulation tho'. PJ

Airfoam Insulation provide an infill wall product, I think they have a website

671905 2009-02-07 20:27:00 I concur. Polystyrene underfloor insulation is great for older houses with wooden floors - I installed it in one of my houses a few years ago. However, I wouldn't recommend pumping insulation into the wall cavities without research first. We did this to another house and the moisture content was so high the house 'bled' for 2-3 weeks and needed repainting (they don't tell you that) and then the interior gib swelled so you could now see all the joins etc. which you couldn't see before. Great for warmth but sh.ite on everything else.
