(The following is a copy of a message my wife & I sent to the Company having completed the installation of our Air ASHP system)....
We just wish to record our thanks to CMS for the excellent service we have received this week with the installation of our air sourced heat pump system.

From the moment we had our first contact in March 2025 with Cameron & Scott, we have been impressed by the overall professional service and the time taken to explain the differences between traditional gas boiler central heating & this renewable energy system.

The moment I met John & Stuart a few days before the work started I knew we were in safe hands. I really appreciated them taking the time to do their site visit on Friday afternoon and outline the process for the coming days.

On the Monday morning they arrived on time and with apprentices Rory and Jack ensured our carpets were protected before starting the removal of the old system.
The enthusiasm of John and Stuart is infectious. I'm sure both apprentices will benefit over the coming years of learning, not just the skills of repairs & installation, but the importance of customer service. They ensured best practise of keeping the customer updated on their progress so that we were reassured throughout the 5 days.
Listening to both gentlemen explain 'how to do the patricular task' they were working on to Rory & Jack at various stages reminded my wife and myself of our 'on the job training' & how lucky CMS is to have vetrans like John and Stuart. You cannot beat 'hands on' experience from skilled workers.

In addition, the electricians who attended on the Wenesday, led by David Hamill were also first class.
Davy took the time to outline what his team would be doing and answered all of my questions before leaving 'Big' Jack and Sean to get on with the electrical work.
All their efforts were first class. A total team effort.

Thank you as well to Scott for personally attending on Wednesday morning when we expressed a concern. By attending and taking the time to listen to our observations, we were reassured and our concern addressed.

On Friday we were left with an amazing energy efficient product. Within hours we started to notice the positives of the air sourced pump heating system. Very impressive.

We are now looking forward to the installation of our solar panels and storage battery in the coming weeks.

We had a fantastic experience with CMS Surveyors, from our initial enquiry through to installation. Their communication was clear and responsive at every stage, making the whole process smooth and stress-free.

The entire team was professional, skilled, and courteous, carrying out the installation with minimal disruption and excellent workmanship. We’re absolutely delighted with how well the system is working and have noticed a significant improvement in comfort throughout our home.

I wouldn’t hesitate to recommend CMS Surveyors to anyone considering a heat pump installation - outstanding service from start to finish.

We were keen to commission a single company certified for both Heat Pump and Solar, and our client experience with CMS has naturally fallen into a sequence which began with the initial competitive estimate and quotation stage.
This was accomplished with professionalism and a high degree of careful analysis including detailed heat loss calculations and strategic design of the eventual ASHP Solar and Battery installations. CMS showed a thorough knowledge of this building type, and are able to adroitly design the installation layout.
The second, more intensive, phase involved consecutive deliveries of considerable quantities of hardware, erection of scaffolding etc. Inevitably, some components did not appear when required, and both (excellent) work teams were at times 'working around' one another and the stack of delivered hardware.
Despite these hitches, the installation teams completed almost all of the work to a very high standard within the working week, with the complete system being tested and commissioned. We cannot praise the quality of the electrical and ASHP system teams too highly.
We have subsequently been able to find a fresh utility tariff that enables us to charge the battery overnight at a low kW/h rate, and have arranged for the gas meter to be removed. Since then the few sunny days have easily refilled the battery with 'free' electricity.
A job well done!

CMS installed an air source heat pump for us. We found their assessment of our needs convincing. They provided helpful support as we negotiated a grant and planning permission - and the team setting the system up for us have been first rate.

I recently had a heat pump, solar array, and battery system installed in my home by CMS Surveyors Limited, and I couldn’t be more impressed with the results. From start to finish, the experience was seamless, professional, and efficient.

One of the standout qualities of CMS Surveyors Limited is their flexibility and commitment to customer satisfaction. They took the time to understand my needs and provided a tailored solution that maximised energy efficiency for my home. They were incredibly accommodating throughout the entire process, answering all of my questions, addressing concerns, and even working around my schedule to ensure minimal disruption to my daily life.

The installation team was top-notch—skilled, courteous, and highly professional. They worked efficiently, kept me informed every step of the way, and ensured that all the systems were properly integrated and tested before completion. They also left my home spotless after the installation, which I really appreciated.

What really impressed me was their attention to detail. Not only did they ensure that everything was working perfectly, but they also took the time to walk me through how the system operates, helping me understand how to maximise its benefits moving forward. The solar array, heat pump, and batteries are now all running smoothly, and I’ve already noticed significant energy savings.

If you're looking for a reliable, professional company to handle your energy needs, look no further than CMS Surveyors Limited. Their expertise, excellent customer service, and top-quality installation make them the go-to choice. I would highly recommend them to anyone considering a heat pump, solar array, or battery system for their home.

Thank you, CMS Surveyors Limited, for an exceptional experience!

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.
