Over on the XE forums people are also getting the £30 bill to renew.
But for an extra year's worth of "Secure" they want £240 for the factory fit tracker service.
I’ve not had a renewal yet, it came from the dealer already signed up but I guess I’ll get a bill in June when mine’s 3 years old and the warranty is up, I also like the tracker for peace of mind so I’ll continue with it.
