Quality assurance and assessments for energy performance from experts in Dumbarton

We were delighted with CMS after the installation of a heat pump, solar panels and storage batteries. Having learned about how essential a skilled installation was to the efficiency of the heat pump, we were sceptical of the salesmen from other companies who attempted sell us a generic system that suited them (as opposed to our property). When the Director of Renewables from CMS, Cameron Bryce, came to the property, the first thing he wanted to do was a proper heat-loss calculation, so we knew we were on the right track. The data generated ensured we finished up with a bespoke system for our 1960s home. Our existing pipework and radiators did not need to be replaced. The installation itself was stress-free: The scaffolding went up in one day, carpets were protected, and work was completed in a week, without any mess being left behind. John’s experience and knowledge of heat-pump systems was impressive and he took the time to demonstrate how everything worked. Mark was on-hand to answer all our questions and coordinate the various teams of professionals during the week; he also setup the two online monitoring systems for the equipment. The solar engineer, Jordan, was available to answer our questions by phone and message as we got to grips with the hybrid inverter. The system was installed in mid-April 2024 when the weather was still cold. The heating, hot water and shower all worked well and the efficiency of the heat pump is better than we expected, even for hot water. The heat pump is surprisingly quiet at only 35dB. Since commissioning, we have only drawn 17% of our energy from the grid and most importantly, our home has emitted no CO2. We would recommend CMS without hesitation and have done so to our friends and colleagues.

The whole experience from beginning to end with CMS was first class, excellent and easy communication, very helpful in the planning design stage and planning permission. Professional, fast and tidy workmanship and an excellent end result. Wouldn’t hesitate to fully recommend.

I had Solar and battery installed. The team were knowledgable and helpful. Everything has been installed and is up and running well. They also provide after install support which is great. Trustworthy company. Would be happy to use again.

I have just had an Air Source Heat Pump, Solar Panels and Batteries specified, supplied and installed by CMS surveyors. The service and support from Cameron and his team through the whole process has been excellent. The installation team, led by John, worked very hard, and they were easy to get along with making the installation a more comfortable process than it might have been. I'm pleased that I chose CMS for this job and have no hesitation in recommending them.
