Thank you for enquiring about the date your TV Licence expires.
In most cases when a TV Licence is renewed, the need for a licence is unbroken and the expiry month of the new licence stays the same. When you applied for your licence in April 2007, it had expired December, 2006 therefore you were issued with a December, 2007 licence.
If there is a reason why the expiry month of your new December, 2008 TV Licence should be different from your old one, please let me know.
ARGHHHHHH!!!!!!!!!!!!!!!!!
