2007 Hawkeye Cat 1 Alarm Advice
 

I didn't realise the used 2007 Impreza WRX Hawkeye I bought just over a month ago was an EU import.

I also didn't realise that this meant it has no Thatcham Cat 1 alarm fitted until after my local Subaru dealer serviced it and informed me so :(

Can anyone suggest some good, insurance-friendly Cat 1 alarm options, rough fitted prices and possibly suggest any good installers in the Kent area?

Thank you very much for your help.
