Flight time changed without notification - compensation?

I have a flight booked today at 6:50 and received an email yesterday asking me to check in for 7:55. The flight number is the same but the flight time apparently was changed. The only trace of my original flight time is my booking confirmation which says clearly the former time. I'm aware that companies may change times but I thought they at least have to notify you when they do.

So my question is, is this simply bad service or actually a case for compensation? For example due to the later arrival time I now have to book a taxi instead of train which is more costly. If they had notified me in time I would have refunded the flight and book an earlier one. I'm based in EU and the flight was between EU countries.
