Alarm in UK that integrates with vera3 that is insurance approved


I am looking to put in a wired / wireless alarm system in a house which will integrate with the vera 3. I know that the dsc will work, but can’t find a nsi approved installer that can supply this alarm, and insurance company is insisting on an alarm installed by nsi installer.

Don’t think that honeywell vista systems are available in uk either?

Thanks for your assistance
