Bank of Ireland mortgage - first time buyer

Have gone sale agreed on a property and have been approved for a mortgage with Bank of Ireland. Mortgage amount 112k over 25 years and I'm a first time buyer. I know there has been plenty of discussion regarding whether to fix or go variable. Is the general consensus to hold tight and wait for mortgage rates to decrease further? What would people consider to be a rate worthy of considering to fix for 2/3 years? Thanks.
