I will deal with those points. On the range of products, when we go from no certification to certification-there is already a certification scheme for microgeneration-it takes time to build up sufficient products and sufficient people with the skills to carry out the installations, but we are determined to drive that forward. On a different point, the right hon. Gentleman said how important it is that there are certification schemes to avoid the cowboy scenario. We need to do the work, and I am keen to do so.

I had not quite finished explaining what we want to do to help people who are off the grid. The social price support, about which several Members spoke approvingly, means that there would be money off the bills of fuel-poor households for their electricity. Generally speaking, people have an electricity supply wherever they live, so off-mains gas grid customers will have the benefit of social price support if they are in danger of fuel poverty.

For those who must pay for heating oil or liquefied petroleum gas and have difficulty with the up-front cost of bulk buying, National Energy Action is carrying out work at the request of the Department of Energy and Climate Change to see whether there are ways-for example, through credit unions-to help people with up-front costs. That could be a significant development.

On feed-in tariffs, our judgment is that people who decided to fit renewable energy sources before we announced the scheme based their decision on the scene as it was at the time. They may have received a grant from the low-carbon buildings programme, but they did their own calculation, so we do not feel too guilty about the fact that the system is to drive more investment in future, not to reach back to reward those who based their judgment on the situation at that time.

The right hon. Gentleman also asked about the location of weather stations and cold weather payments. The Department for Work and Pensions reviews the locations every year and takes into account the representations made by hon. Members and the public. I remember statements by that Department of changes that it had made in response to representations. I urge right hon. and hon. Members to make their representations.

I have so much more to say just in reply to right hon. and hon. Members' questions, but on the issue of confusion, no one has mentioned Consumer Focus, the consumers' champion. I am keen to support it, so that everyone talks about its role-its help is very significant.
