eligible to vote in UK?

I received a letter last night saying that I need to return the elector information form with updated details of occupier of my current rented property. Then I realise as a citizen of a Commonwealth Country. I have the RIGHT to vote in UK! Sounds unbelievable but that is true. I have missed last election in Malaysia due to the fact that I was not 21 by end of the registration date. But over here I have a chance to vote as I am over 17 and have to right nationality. I do not know whether that is a blessing or not. But frankly speaking I am more concerned with the coming election in Malaysia because that affect me and my family members more. I think if we could not get the right people into the government, the public works in Malaysia will fail. Then this country will become less safe and more diificult for people to lead a good life on. In the end, I may have no home to return to in future. So the opportunity in UK maybe a good lesson for me. Though the reason for me to register myself and my housemate is to avoid being fined £1000.
