Why don't we sell online?

ControlFreq has been selling online since 2009.  We're now actively seeking reseller partners.

Over the past two years we have developed the 'Alpha Control Ecosystem' [ACE]. We have made the decision to concentrate our focus on the core technology, as a manufacturer & cloud service provider, while hardware sales are channelled through online partners.

New and existing customers can  purchase directly from us, offline, until suitable Reseller channels are in place, at which time we will direct all online sales through partners. This is a transition we have decided to make to focus on 'Made in Britain' manufacturing &  the connected services to compliment our products.

If you would like to become a reseller please connect with us to arrange an intro call and demo meeting.

All technical support and paid services like contract SIM cards, managed services & cloud management subscriptions will be provided by ControlFreq directly.

When an end purchaser activates a ControlFreq product, these services become available.
