5* Company
We had our boiler installed by Marshall & McCourt two years ago, and the outstanding service we received then continues to impress us. Recently, we received an email reminder from them regarding the upcoming service for our boiler was due. I promptly contacted them and scheduled an appointment for the service the following week.
The experience with their engineer was nothing short of excellent. The engineer arrived punctually, conducted the service with remarkable efficiency, and displayed a level of professionalism. The entire process was swift, yet thorough, leaving us with the assurance that our boiler is in top-notch condition.
We appreciate Marshall & McCourt's commitment to proactive communication and their dedication to providing exceptional service. It's evident that their team takes pride in their work, and their expertise shines through. As very happy customers, we highly recommend Marshall & McCourt for their outstanding service and reliable expertise. Thank you for consistently exceeding our expectations!
Periodic service of heat pump
Periodic service of heat pump: friendly efficiently carried out as usual, and same price as last time. Highly recommend this company.
Excellent service
All the people we dealt with in the installation of our solar panels were polite, informative and did what they said they would do. We had no difficulty getting in touch when we had any queries and everything was carried out as discussed.
Excellent service
The engineer arrived as scheduled, very courteous and obviously very skilled. Very good inter person skills. Very happy to have found this company and know I will use them regularly for my gas boiler.
Air source heat pump installation
Marshall & McCourt are a very professional company that puts the customer first. Everyone you meet is very friendly and helpful. All questions are answered. The installation team clearly wanted to do the best job for the customer and took pride in their work. They communicated with us whenever necessary. They respected our home and did the job with as little disruption as possible. The result. An ashp system that works very well.
We would definitely recommend Marshall & McCourt.

Efficient, knowledgeable engineer that serviced our air heat pump
Excellent
Excellent, quick and friendly service. Cheaper than other services in the local area. Thank you to all involved.
Overpriced and patronising salesman
Had a quote for a boiler and radiators. The engineer was patronising throughout the full 45 minute sales pitch and then the quote took over 2 weeks to be emailed to me. This quote was over £1,000 more than similar competitors and therefore disregarded very quickly

Gary came to do a service
Gary came to do a service. He’s very personable and takes great care in his work.
Good experience, would highly recommend to others interested in renewable options.
Really impressed with Ryan and the rest of the team. After an initial mis-communication at the beginning of the design process, Ryan and the team have been great. They have worked with us to help get our new heat pump installed and commissioned.
The team at Marshall and McCourt have been incredibly efficient and professional throughout with overall good communications regarding timelines, on-site days etc and the final result is reflected in the quality of the work that the team have delivered for us over the entire project.
As we are on day 1 of having the ASHP installed, I cannot comment on the system much apart from the fact the house is now starting to feel warm again! One set of happy customers later, we would recommend M&M to anyone looking at moving away from gas to more renewable sources.
Toilet repair
Very efficient, Arrived at the time agreed and diagnosed problem quickly Very reasonable price
Highly recommended for all plumbing and heating services
