The more standard phrasing is Our office will be moved to the following address, effective 1 January 2014: [address here].  I hope this helps.

In Britain  with effect from is more common, sometimes abbreviated to wef. 


Effective is also correct but not  with effective from

People say "with effect from" often enough that it has an abbreviated version? Is that text speech or something that has been around a long time?

It certainly pre-dates text speech, Patty. In fact, it's in my 1993 edition of Chambers Dictionary.
