Andrew54, my opinion would be do not ask on a renewable energy forum who we would vote for.
Most people on here have worked hard to build a financial future for themselves, some have done it to make the world a better place, but most have worked hard for both reasons, only to be messed around for 2-3 years by politics, politics that have come from the 3 main parties, all absolute numpties that do not have a clue, who change their minds constantly, (recent thread on here from the DECC and comments that started with Chris Huhne and changed month by month, it was an interesting read) also they write new legislation that is so complex, fundamentally flawed, and to be honest unworkable.
It is a shame that politics have to be involved with it at all, I for one will never work in any sector ever again in my life where some lying, cheating, money grabbing, back peddling, expense claiming, half wits have a say in how I work or how I earn...
I hope this helps.
