New ASHP system in our new build home.

We required an ASHP system to be fitted in our new build property at relatively short notice after being let down by another provider.
Ryan at Marshall's was quick and efficient at this stage in getting me quotes, answering any questions that I had and booking me in. His quote was also good value we thought for high quality products.
The guys who came to fit the system were very pleasant. They fitted all of the equipment very neatly and other tradesmen have commented about what a neat job they have done.
Matt provided a good handover session to my husband and I to help us understand how to use the new technology. After about a month now in our new home the system is working perfectly.

The team from Marshall’s were professional, skilled and considerate. From the first visit to the completion of the heat pump installation everything was positive.
I would have no hesitation in recommending them.

Highly recommend Marshall Clean Heat

A great company that have undertaken work on my home with solar & inverter/battery and for projects a Trust I work for that funds community projects.
Lovely team of workers, polite, tidy and the administration team at Marshalls are always willing to help and advise on installations with professionalism and friendliness.

Efficient and reliable

After the installation of our heat pump we continue to have it serviced each year with Marshall.
They contact us each time and remind us that a service is due.
The engineer always arrives at the time given and is very helpful and friendly.
We have had no problems with this system and would recommend Marshall 100%, they are efficient and reliable.

We used Marshalls to install our ASHP…

We used Marshalls to install our ASHP initially over a year ago and when we wanted to complete our eco upgrade to include battery storage and an EV charger (we already have solar panels), we went back to them.
We shopped around for quotes on both occasions just to play it safe, but we didn't hesitate to use them again.
The office staff are friendly and efficient. The engineers are knowledgeable, friendly and crack on with the job.
The only delays were because of Northern Power grid but that couldn't be helped and is because of our location. Though we're in North Yorkshire, the company were very happy to install and service our equipment, and we met them in their offices once too when we were in the area.
It feels like we've spent a fortune with them, well we have really but that's because we would rather pay for top quality products and service, but we would definitely recommend the whole team. I think we are fully green now but will continue getting our equipment serviced through Marshalls so look forward to catching up with the team annually.

We had a burst pipe on our own house (Marshall’s have been helping us with a new build we are undergoing installing air source heating)

Cannot fault them had an engineer out within the hour stopped the leak and was able to keep the heating on over night (which was really appreciated with my Nana being 82)

Came out first thing in the morning renewed the two pipes in that area

All flowed like clock work and took a lot of stress out of the situation

Thank you to every one especially Steve 👍

the company has been efficient and helpful in the whole process from planning to commissioning of our ASHP. They have been transparent about costs, professional about installation, friendly, as careful about our house as they could be - including care for our cat - and knowledgeable about their work. They have been very helpful with regard to queries, and quick email and telephone advice.

Excellent Quality Company

As always excellent Service. I’ve dealt with Marshalls for some years now on two properties involving installation and service of Heat Pumps and Solars, they are an excellent company.
Gary (2 sugars), the heating engineer who has installed and serviced our systems is first class, as are all the engineers, electricians etc that have attended.
