Marshall Clean Heat and Power Ltd is widely praised for knowledgeable, friendly engineers and helpful office staff who keep customers informed throughout installations and servicing. Reviewers frequently highlight smooth installations of air source heat pumps, solar panels, batteries, and general central heating, appreciating tidy pipework and dependable aftercare. While the broad consensus is very positive, a small number of customers have experienced frustrating communication issues, including unreturned calls and disputed quality during complex heating jobs.
Good quick service fitting a new radiator. Very personable. Customer service always great.
Great service, quick to follow up fault on daughters boiler when called out. Always friendly great service
Great service as always from Marshall Clean Heat. Had our ASHP serviced . 3 years since we had installed along with UFH,Solar and Battery and all run exceptionally well.
First class customer service. John the electrician was very friendly and professional
Felt confident with the heat loss survey and good explanation of findings. A very detailed proposal produced. Good price for the amount of radiator changes and pipework.Team worked really well to install air source heating system, keeping us aware of progress and asking opinions on proposed piping routes etc. Good teamworking to get things done in a timely manner. Always tidied up at end of each day. Very happy with end result and can highly recommend.
They put in my whole central heating with underfloor heating and radiators upstairs in an old 6 bed Edwardian house. System is amazing been in hpuse 25 yr and it now feel so snug and warm and costs me less to run too. They have serviced it last 2 years and i have had no issues. Very pleased that i chose this company out of all the quotes i had. I had no idea who they were before but i have been delighted by the system and the service
Superb prompt service, Office staff always very helpful and polite, Service staff always very knowledgeable and friendly. Explain the problem and explain how the job will be done.
From start to finish excellent service all round. The installation team were exceptional, knowledgable and extremely tidy. Would highly recommend the team at Marshall. Thank you.
Friendly, professional and surprisingly fast installation of air conditioning over two days in my home. Really pleased at how tidy the external work is.
I have used Marshall's for years and have always had 5 star service. Recently I had no hot water and they came the same day and problem was resolved. Staff are always friendly and helpful. I would recommend without hesitation.
Really pleased. We have used this company for years. The quality remains high. Polite. Great, helpful staff and good after sales service.
Marshalls do exactly what they say on the tin! They are prompt, professional, knowledgeable, friendly, and they arrive when they say they will and do the job properly the first time! Value for money too. We have used them before and will certainly use them again.
Marshall Clean Heat and Power Ltd (formerly Marshall & McCourt Plumbing & Heating Contractors Ltd) completed most radiator installation, but refused to connect our bathroom radiators themselves, blaming a plumber, and tested the system with them clearly disconnected. They damaged and scratched walls throughout the house, showing visible frustration when asked to be careful. They provided screeding but refused to lay it, and flooded our kitchen twice, showing no responsibility. Workers were rude and ignored reasonable requests. They cut the outdoor power cables for our shed without telling us, which my husband only discovered when he returned home. We tried repeatedly to contact Lee, the supervisor, and asked for the promised monthly service reminder, which they refused to provide. Every time we tried to contact the lead, he was “busy,” and nothing was done as agreed; many promises were lies. We do not recommend this company.
Good team
Fantastic company We had air source heating installed last year and it’s been great form of heating from our original coal fire back boiler system This last week it went wrong and things went wrong with it (which like anything can happen) But aftercare from Ryan, jason and Rachel all has been amazing, they came straight out and identified the slight issue solved it straight away Cannot thank them enough and it’s really good to know their after care is as good as their installation process Don’t bother going any where else, even if the quote is less expensive, you get what you pay for and that’s a service second to none. Being warm in these winter months is a priority in any home and this company can deliver on it!!
Very helpful and cheerful team. Had them inspect and repressurise my solar thermal system, and perform service/inspection
Solar and battery installation a couple of years ago and air to air heat and cooling this year, all professionally installed and excellent customer service.
Installed solar PV and heat pumps at our village hall. Excellent work and a quality installation.
I have just used Marshall and McCourt to have an outdated, non functioning solar thermal panel removed off the roof . The heating engineer was lovely ,firstly he turned up when he said he would, he assessed the job and arranged for a quote to be sent out . An email quote was sent out detailing all the jobs to be included and the price to complete them . Once I accepted 2 plumbers arrived on time, they were both pleasant & polite . Despite the awful rainy weather they worked hard to complete the job quickly & efficiently and tidied up as they went . All in all a quick response, excellent service at a good price . I would definitely recommend this company and would use them again 😀 A *****
We have used Marshall and McCourt for many years . For Boiler , bathroom work done . Just had a new boiler fitted last week and can not fault them at all . Quick to reply and price job up . Lads were on time and so clean and tidy . Would highly recommend this company .
Heating always going off, still no further with getting this sorted. Also out hours on weekend goes through to answer phone and no one gets back to you. Certainly would not recommend nor would I be using this company in the future very unprofessional and not well organised
Was told I would receive call to make appointment to cost work involved full heating and domestic system no response from them to date.
Explained everything very thoroughly, the pros and cons of installation of a new air source heating system, very honest knowledgeable and helpful.
Great service reasonably priced and very professional service highly recommended
Quick and easy to arrange. Professional service
I used Marshall and McCourt to install a garden tap. They were the only business to respond to email enquiries and did so within 24 hours. They gave a fast quote and the work was done within a week of first contact. The engineer who completed the work arrived on time and was so lovely! He made a point to speak with me and have a chat whilst doing the work, rather than just get on with it in silence. I was able to pay over the phone and the woman who took my call was cheerful and happy. Impeccable customer service and an amazing job provided. Would 100% recommend and will be using there services again if ever required.
Great service from a local, professional and friendly team!
