i'm not sure i can offer much thought here. the balls up is clearly on employer's side here and it risks you ending up with an embarrassing departure on your cv
legally, as others have said, you have little employment protection with less than 2 years service, but if an employer took me on, then said after 9 months that i needed a certain qualification to do the job, i'd be a bit pissed off
gut feeling is the best outcome is going to be redundancy as a result of your office closing. you don't get redundancy pay with less than 2 years' service either, but that's probably the best line to have for future job hunting.
but no harm in talking to acas (or seeing if you have any sort of access to legal advice through insurance policy, professional body or something.
