Marshall Clean Heat and Power Opiniões 

As usual, booking the appointment was easy, the young man making the booking was very helpful. The technician carrying out the service was knowledgeable, pleasant & efficient.

I first contacted Marshall Clean Heat and Power because my existing SolarEdge inverter wouldn't connect to wifi after Virgin changed my router. Although I wasn't a Marshall customer, Jason helped me get my inverter back online, free of charge.
I was so impressed, I asked Marshall to give me a quote for upgrading my system to include a SolarEdge storage battery. This work was completed to a high standard and I'm very happy with my installation and the performance of my battery.
Marshall Clean Heat and Power have been a pleasure to deal with throughout the whole process of quoting for and installing my new battery and inverter. I've found all of their employees to be friendly, courteous and professional. From my experience, this is a professional, trustworthy company who wants to do everything correctly and provide a good outcome for its customers. I have no hesitation in recommending them.

Great service, arrived on time, efficient and effective. Highly recommended.

Great service from beginning to end - very professional company

We used Marshall & McCourt to install our heat pump and have continued using them each year to do the service. Gary is very polite and professional. He arrives on time and always does a good job and is very thorough. If you have any questions he always has time to provide an answer. We look forward to continuing using Marshall & McCourt in the future.

Following a very successful installation this week of a complete new central heating system, Solar PV with battery storage, I wanted to extend my sincerest thanks to all your teams, whether office or on site for their dedication on meeting my specific requirements. Their meticulous attention to detail, problem solving and commitment to fulfilling my needs hasn’t gone unnoticed.
Can you pass on my thanks to all Involved and it goes without saying I throughly recommend Marshall & McCourt

Booked service for heat pump, kept informed as on day engineer was delayed by 1hour. Did job with no fuss. Left place clean and tidy.

I write to thank Marshall & McCourt for arranging the installation of the Solar Panels and storage battery at our home on the 25th and 26th March 2025.
The “team” who carried out the installation worked very well together, explained and sought our permission before they carried out the various aspects of the work.
They were patient when answering our numerous questions and made sure that we installed and understood the Tesla App correctly before departing.
We would have no hesitation in recommending Marshall and McCourt.

Boiler service carried out quickly and efficiently as usual at a fair price.

Great service as usual, Clean and tidy inspection.

Fantastic company, brilliant advice and flawless instillation, super happy

Recent installation of a air source heat pump went very well from the initial consultation to the final commissioning. Steve and his team worked very hard throughout the installation. They were tidy and careful and protected our home from mess. The whole of the team were very professional. Many thanks 😊

Prompt service friendly engineer and job well done

I have had great service from Marshall & McCourt over the last 4 years. They have done a lot of work for us: installing an air source heat pump with replacement of all radiators and pipes, installing an electric shower, and (within the last year) relocating solar thermal plumbing in our loft, installing solar panels & a battery, and installing an EV charger. All their staff (both in the office and on site) have been consistently helpful, polite and reliable, and have resolved any issues promptly. I can thoroughly recommend this company.

Solar water station replacement went very well . Clean and efficient job communication from company excellent.

I found this company to be efficient, reliable and easy to deal with. They are reasonably priced and offer a good service.

Marshall and McCourt are very reliable and professional I have the upmost faith in them as a company and they are reasonable in price

I have used Marshall and McCourt for many years to service my boiler and also, occasional plumbing works.
The office staff are unfailingly helpful when arranging a suitable date for the engineer to visit.
In turn, the engineers always turn up on time and are friendly and professional while carrying out the necessary work.
