I agree with the hon. Gentleman. In many stone-built houses without double glazing, the energy-saving light bulbs that have been sent through the post are piling up, when different sorts of help would make a bigger difference. He is right about the transparency and support in CERT schemes. That is also a problem with social tariffs, which can be hard to understand and to get information on because of the complex systems that vary from company to company. Those things militate against people receiving the help to which they are entitled.

I wish to raise a number of issues with the Minister in relation to hard-to-treat homes where heating oil or LPG is the main energy source. The first point is about regulation. There are obligations on major utility suppliers, such as gas and electricity companies, to engage in schemes such as CERT, to provide support and to offer social tariffs. There is no such regulation of heating oil providers. There is also a major gap in the access and involvement of statutory consumer bodies such as Consumer Focus, which take up and pursue issues.
