Flixbus have applied for a UK PSV operators licence, perhaps suggesting they're going to start services within the UK. Certainly will be interesting times if so. The operating centre given is based at Whippet Coaches in Cambridge, however the office address is a block in Bristol. It looks as though Flixbus UK Ltd was started in April but has only recently put the licence application in. The company is entirely owned by Flixmobility in Germany.
