Marshall Clean Heat and Power Avis 

Very accommodating and fair in their dealings with you. Very pleasant helpful staff. Quality of workmanship is very high. Would highly recommend.

They sent their salesman out who was very informative and professional. Upto know a really good service.

Very happy with both the speed and professionalism displayed by the engineer.

M&M delivered a first class product on a less that straight forward site. I am grateful for their problem solving and working with the owner to achieve a top quality outcome. Occasionally they needed a push to complete the works in good time.

Everyone that came out was friendly, considerate and knowledgeable. They moved my boiler from the cupboard to the kitchen and were tidy (well as tidy as you can be installing a boiler) fitted a new radiator and thermostatic valves on my existing radiators. The service from start to finish was fantastic and my home has never been so warm. All of this for a reasonable price and guarantee.

Very easy & accomodating process. Reasonable price. I have no complaints. Thanks to the team.
Mrs Nadine Crosfield, not Mr.

Always remind me that heating needs service. Arrive promptly and spend time to do proper service. Very polite.

We have now has our ASHP,Solar PV , Battery and UFH heating system installed for a year trouble free. We arranged a service for our ASHP that was carried out quickly and efficiently thanks to Marshall and McCourt.

I have found Marshall and McCourt to be an efficient and dependable company to deal with. From installation through to ongoing service and maintenance, the continue to be my preferred supplier.

Usual proffesional work and attitude, have used this firm for a lot of years for our instalations and services etc,

Everything was done well and on time. The system seems to be working well now. I don't know whether there will be any follow-up, but if everything continues to be good, next year I will be considering a service contract.

I was reminded by the company that my boiler required it's annual service. A date and a time was arranged approximately one month ahead. The engineer turned up on time, was friendly and professional and performed the service, tested the installation and left the boiler in a clean and tidy state. This may not sound remarkable but I have experienced many services from other companies that didn't go so well - appointments not honoured, boiler faults unresolved and boiler area left looking like a bomb site.
I can thoroughly recommend Marshall McCourt as a company who deliver on promises and care about results

Had a very old central heating system in an old house replaced by a modern system. Including ground floor underfloor heating. So impressed by knowledge and professionalism of the team . I was having other building work done at same time and teams worked collaboratively.

So happy with the final system . Recommend them 100% I am going to have them service it ongoing a1

Marshall and McCourt did an ASHP and underfloor heating project for us, from initial discussion though the design phase and to then doing the installation.
Can't speak highly enough about the team that came and did the work, very professional finish but also very friendly and helpful team.
They were not the cheapest quote we got (but definately not the most expensive either), however for large projects like ASHP and underfloor heating, its absolutely worth it for the attention to detail and post-work guarantees!!

Reliable, professional and reasonably priced

Tony explained everything clearly including the siting of the ASHP and need to get planning permission. He was available to answer any queries and responded promptly.

Excellent service, they get the job done, very professional, tidy, polite, knowledgable and personable

Excellent. Annual service completed. Knowledgeable, clean and tidy, thorough and prompt.
Highly recommended
