I've had cavity wall insulation added to the last two houses I've owned. Made a huge difference to both, especially noticeable was how much longer the house stayed warm when the heating was off. Both were detached which will make a difference in terms of surface area impacted.

Yeah, I know the benefits, just worried about the damp issues. We are on the boarder line of areas where it can start to be an issue, worked out based on amount of rain and wind as I understand it.
