It covers anywhere that the HPM magazine is circulated, although to be honest it does have a south east bias, because thats where our branches are located, and lots of our customers complete the survey card in the branch (or at least they pick up the card from the tradecounter, even if they fill it in later and return it anonymously.)
There is some data for Scotland and Wales, but its a bit thin to be drawing conclusions from.
We are just starting the process of collecting the data for the 2013 survey, and are making an online version that we will promote via this forum and via twitter etc, and so hopefully get more data.
I think that some of the criticism regarding sample size in the posts above do make a fair point. Unfortunately, we don't have the resources to mailshot the entire Gassafe register, but the more reponses we get, the more useful the data becomes, particularly when looking at regional trends, where inevitably you can only look at a subset of the data.
