CTC UK Reviews 

Very helpful and knowledgeable when it came to set up of this heat pump equipment!
As an installer it made commissioning of the system straightforward

Had a problem with my heat pump, sent a video & info on the fault to Igor in technical. He responded immediately with advice & photos to help identify the fault. Sent out the required part next day, which my electrician fitted.
Then Igor helped via video call with the settings (at the weekend!). All good now.
Excellent service - Igor couldn’t have been more helpful.
Thank you so much 😊

Great technical support. I have been installing heat pumps for 10 years. Installed correctly CTC heat pumps give you great control and reliability over your heating system. Quality products.

New install today, called technical support for assistance with the wiring. Jake was brilliant and gave all the information I needed. Always available, very easy to deal with. Thank you for the help Jake, pleasure dealing with you. Highly recommend the system and your support.

Complaint Regarding Persistent Product Failures and Inadequate Support

In late 2018, two systems were installed in near-identical properties. These systems failed to function properly for the initial few months, requiring numerous visits from a CTC Technical Manager. Despite repeated attempts to resolve the issues, including one incident where the manager fell from a ladder and caused further damage by pulling pipes down, the problems persisted.

Approximately six months after installation, the cooling module in House A failed and was replaced under the supervision of the CTC Technical Manager. Over the next four years, both systems consistently underperformed, resulting in cold homes during winters, an inability to fill a bath more than halfway, and repeated failures of sensors and heat plates.

In 2024, the cooling module in House B failed and required a two-month wait for replacement. A second cooling module was installed in September. Shortly thereafter, the cooling module in House A failed again and was replaced with a third module in November.

On Christmas Eve, the second cooling module in House B also failed. As of now, we are awaiting a response from CTC Sweden, as no replacements are reportedly available in the UK.

The repeated failures, prolonged delays in obtaining replacements, and inadequate performance of these systems are unacceptable and warrant immediate resolution.

UPDATE PENDING

Recently had a CTC Ground Source Heat Pump installed. Needed help with some settings on the control system. A quick video call with one of the tech guys and it was all sorted. Very helpful and friendly to speak to.

Excellent heat pumps made in Sweden.
Great technical support from Igor and the team.

A very good day with the GoGeothermal team as always.
Igor is an absolute rockstar in the heat pump world and was very helpful with all of our questions.
We are looking forward to fitting some CTC units in the not too distant future.

Easy communication on great advice

The training was extremely informative. We had Heat Pump Installers & Design Engineers attending the course & both found the information provided & course extremely useful.

I got a strong sense that the CTC team were completely bought in to making my installation a successful one. This was confirmed with the detailed fine tuning the Design Engineer completed to ensure optimum performance. 2 years of trouble free and very efficient operation give further confidence in CTC UK.
