Overall excellent experience working with Marshalls. Knowledgeable sales team, technically competent personnel and first class installers! They really listened to what I wanted, guided me and delivered a fabulous solution. Don’t hesitate using this company for your clean heat and power! 😊

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, professional service
Gary always provides an excellent service, on-time, professional and polite
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.
Service itself was good but there were issues.
Service itself was done to a good standard by a pleasant and professional engineer.
However overall communication was poor. Service was booked for 12.00 and heating was switched off from 9.00am to let everything cool down. It was a very cold, wet and snowy day. By 12.30 no one had come so I rang MCHP to query whether he was coming. They said he'd been delayed and would be there around 2.00pm. By 2.30 pm no engineer. So my wife rang MCHP again. They said he was now in Norton and would be another 40 minutes. Sure enough he arrived at 3.15 pm and the service completed. Our main gripe was that the company should have been notifying customers of the delay rather than them having to contact MCHP for updates. Especially with the cost of their service having risen 20% in 12 months. I could have saved a lot of money by having the service done by somone else.

Good job Keith, excellent service!
The engineer arrived within the agreed time frame and completed the work including resetting the control app with minimum fuss and no mess.
Tip Top Service
Thank you for the quality of your recent installation at my property. One word, faultless.
Your guys arrived nice and early and were well prepared.
The utilities were re-routed quickly and without any hic-ups.
The Powerwall installation team were very much on the ball from the outset. The Team Leader was very well mannered and provided me with an ongoing update of what was being do, why it was being done and how long it would take but always asking if what he had proposed was acceptable.
All in all a smashing bunch of lads who deserve credit. Please pass on my warmest regards to the guys.
Great service. You will be getting a call next year for some additional work. Thank you.
Once again a really prompt and helpful…
Once again a really prompt and helpful response from M&M team . Prompt responses from the office service team and a visit from John sorted out the problem caused by a change of router ! They are a very reliable company and I wouldn’t hesitate to recommend them !
Quick and effecient service on my boiler
Quick and effecient service on my boiler. Done the same day i called.
Excellent service

The perfect Plumbing company to deal with. Always prompt attention shown both on the phone when arranging a call out, to coming out to fix the problem.
First ASHP service
Good company to deal with.
Good value for money.
Prompt & comprehensive paperwork trail, following visit.
Awarded only four stars, due to having to contact the engineer after they left, to sort out a small issue; otherwise, would have been a five.
I would recommend Marshalls to anyone
I would recommend Marshalls to anyone. Gary is a great guy who has kept my ailing heat pump working fot the last few years. His work is of the highest quality and he is always very polite and friendly.
friendly and helpful …
Pleasant and friendly service made this man a welcomed guest
High quality heat pump install.
We have had our heatpump for 6 months and it has got us through 1 winter. The system worked much better than our old gas boiler and saved us money at the same time. The system gets better than the promised design COP (efficiency) and is easy to use.
The install process was painless, all of the govt grant details were sorted for us. The survey was very smooth and they listened to us about component placement, the locations we wanted weren't the easiest but they were the only installer willing to put equipment where we wanted it to minimise space use. We had every radiator replaced and the quality of the install was great all additional pipework and cabling was hidden in the floor void so the install looks like it was original to the house not a retrofit. Some of the radiator sizings were increased at no cost just so we didn't need to re-wallpaper rooms (radiators matched dimensions of original radiators), we didn't need to redecorate anything once the install was complete. Installers cleaned up thoroughly after themselves and left the house clean and safe after every day of work.
Installer came back a couple times to tweak the install and replace a faulty pump, this was done quickly and without bother or cost.
Pricing was competitive with other quotes and the quality of the survey process was better than other installers and the overall system design was superior and didn't cut any corners. We had a project manager as point of contact for the install process and the staff used were skilled and polite causing minimal disruption.

Great service
Great service, very responsive. ASHP review requested and booked in for the following day. Friendly and knowledagble heating engineer.
The Air Source Heat Pump was installed by Marshall and McCort in 2020. Has run perfectly since. Warmer house and lower bills.
First class service
First class service, knowledgeable, experienced & highly accommodating. Great installation & personnel.
