The Irish banks may well start to increase their variable rate mortgages - regardless of what happens to ECB rates (PTSB have already) - so looking at historic ECB rates may be of little use to you.
To help reduce any worries or doubts about going fixed or variable - why not ask the lender to split the mortgage - fix half for 5 years and leave the other half variable. BOI are actively promoting this idea. It might not end up being the cheapest option - but then again it will not end up being the most expensive either.
