I agree hybrid "A joke" was harsh from someone who's normal position is more akin to yours. However even he cant match your twaddle above, who's talking about saving the world single handed ? They do, its called - VAT at 5% for energy saving measures. Why would a government (elected by you) not expect heating professionals to take responsibility for advising customers of their duties under the Law when having controls installed, who else would you suggest is suitable for that role ??? What have I fallen for hook & line ? the fact that we are all living on the same plant as one another & how is it at the expense of your business ? It is only because there are people like you who are willing to carry out installs without complying that there is an opportunity for a cost difference.
