Your contract doesn’t end on Dec25th , the minimum term may well end on that date , so you can quit without any early termination charges, but as stated , do nothing , the ‘contract’ simply moves to a 30 day notice to quit , and if your intention is to use another provider using Openreach , they serve your notice to quit not you , if you are leaving OR network completely and you wanted to end as close to the 25th Dec as possible then that date has already been and gone , if you are leaving Openreach and serve notice yourself today ( 15Dec ) then it will be around 15 Jan the service ends , so 10 days of your minimum term and 20 days on an out of contract basis , if switching to someone else on Openreach then if the new company start the ball rolling today the migration will take place in around 10-14 days but obviously Xmas day and Boxing Day may affect the actual date of migration
