We need to identify your alarm panel on our list of connected security systems before renewing your subscription. So please fill in all relevant information. If your billing address is different from installation address or if you need to renew more than one burglar alarm panel at multiple locations please make sure you mention the installation address(es) in notes. The price of the App is per security alarm and not per App user. We can renew the App for alarm panels installed by us (Smartech Security) only. There is an admin fee of £5 for any refund requested!
