A few months ago, our elaborate CBus home automation system was knocked out by a massive power surge during a severe electrical storm. However, after the initial replacement of the main power module by another C-Bus company, not all our CBus services were restored. It was only when Control Freq took over that all systems were rapidly restored. Harry (owner) and Andrew (tech) were so impressively professional, helpful, and knowledgeable that I cannot recommend them highly enough. If you're after a CBus specialist company, I believe you couldn't find better than Control Freq!

I undertook substantial research on companies that specialise in Dynalite Systems in a Residential setting. ControlFreq was the only company that responded. Harry took it upon himself to understand the underlying technology and my requirements in providing a solution. The ControlFreq team mapped out a system and hardware upgrade path. From the initial assessment through to implementation I was kept informed at every stage. The final product is of very high quality and has added real value to my property.

I have a relatively complicated aging and undocumented Cbus system and the team at Control Freq handled it wonderfully. Every step of the way was clear and reasonable and the results work great. I recommend them if you need a cbus technician, great stuff!

Great company.I Spoke to Harry and then to Louise. They were very helpful and upfront with everything. The technician who came to our place a few days later was punctual and fixed the light switch which was connected to our Cbus. I couldn’t ask for better than that. I highly recommend them.
