“From a sceptic to 100% believer.”

"I must say thank you for your input and advice in relation to the audio- lighting and all other aspects of the Control4 system. From a sceptic to a 100% believer in Control4 is how I would describe myself. I could not imagine why anyone would consider building a home without building in some sort of system, particularly if the home is in the higher price bracket."

— John Rae

“No hesitation in recommending!”

Derek from Techknow has a real ability to listen carefully to the client’s wish list and to concisely explain what can be achieved, and to implement it without fuss in a cost effective manner. The Control 4 system that he installed has proven to be reliable, flexible and capable. I have no hesitation in recommending both Derek Crane and the Control 4 system to anyone considering an intelligent home automated system.

“I would have no hesitation in strongly recommending Derek based upon my experience.
He delivered great professional service, no hard sell, and really quick delivery and installation and the outcome is much more than we had hoped for”

 - Dr Dwayne Crombie
Managing Director, Bupa Care Services


“Have been exceptional.”

Derek’s punctuality, workmanship and after sales follow up have been exceptional. As a qualified electrician myself, (and a pedantic Virgo), I took particular note of how the installation was carried out and at no time was there a need to raise question. The pride of professional workmanship was clearly evident.

— Stuart and Julie Hellyer

“Lived up to expectations.”

I am thrilled with the end result and have no hesitation in recommending Derek and the team at Techknow. In fact I have done so on a number of occasions and each time Derek has lived up to expectations.
