HI there!

I made a booking for an FB flight from SOF to LHR for June.

My SOF-LHR flight was supposed to depart at 06:00 and now has been moved to 06:25. This is not a problem.

However, my LHR-SOF return flight has been moved from 22:35 to 17:05, which is a major change as well as an inconvinice.

I was not made aware of either change and found out by accident (browsing the airlines website)

What are the EU regulations for this? Are there compensation rules or refund rules?

I have e-mailed the airline and simply asked for an upgrade.
