I just saw that Aegean will be moving their Larnaca - London Heathrow flights to Gatwick.
Larnaca - Gatwick 12:30 -> 15:30
Gatwick - Larnaca 16:30 -> 23:10
From what I could see the cheapest fare is €233 which is not bad at all. Currently LCA-LGW is operated by easyJet.
Cyprus will be linked with Heathrow by both Cyprus Airways and British Airways.
On a side note Aegean will be launching two weekly flights from Larnaca to Kiev in March 2013.
