Easyjet - Belfast

Ballantyne78

So, I booked flights with Easyjet from NCL to Belfast, in order to attend a concert. Concert is now cancelled due to C-19 and I was expecting to either lose the cost of the flights or have to transfer them to alternate dates/destinations unless EJ cancelled.
Now however, they've emailed to advise that they're moving the departure time of my return flight forward by 3 hours. 
Does this affect my rights of cancellation as they would be inconveniencing me under normal circumstances? Or am I still stuck with flights I no longer need?
Any help or advice would be appreciated.
