Fixing interest rate after being on variable

Hi,
I am currently coming out of my first year fixed interest rate on my mortgage repayments. I received a letter from my bank giving me the various options I have this year. Can anyone tell me if I choose to go variable now can I fix my interest rate then after Christmas?
At the moment we can afford any interest rate hikes but I am changing jobs in February and my salary may change so won't be too sure then if we can afford a possible hike.
I tried ringing my bank but keep getting put on hold.

Thank you!!!!!

I presume that you can fix your rate any time you choose. Your lender should able to confirm or deny this.

the fixed rates that are on offer today - may not be available after Christmas.

So you can fix at time whilst on the variable rate, but the rates on offer at the time you choose to fix will depend on the prevailing market conditions at the time.....

also note that when we asked ptsb about fixing our rate we were told there was an administration charge of €100!!

Hi,
I know the rates may change after Christmas and might go up or down (hopefully down). We are fine at the moment but just wanted to check if we could decide at a later date to fix.
€100 crikey, I am with PTSB too so will keep that in mind. Thanks!!

The administration fee may be negotiable if you're prepared to play hard ball. See this thread.
