I think there's a good chance that the prime minister, government, and your local MP REALLY BELIEVE that the UK Microgeneration Scheme is working well. I suggest people contact their local MPs with a copy of the response and point out what a waste of time the government grant scheme is.
You don't even need to waste money on a stamp - here's a website that allows you to contact your MP by email (they are duty bound to respond, so you won't get ignored, and I can vouch for its effectiveness, as I've used it a few times).
