Testimonials

"Blown away by the final result of our new bathroom. All the lads were professional, clean and tidy, polite and happy to help with any questions or advice. Special thanks to Luke who kept us up to date on everything that he was doing and helped everything run smoothly, really knows his stuff, top man! Also to Gary the Tiler, first class. We couldn't be happier, thanks again to all of you involved."
Mr Taylor, Hartlepool
“We had been considering a number of green energy options for our home. It’s good to know that there are experts who can advise on the most appropriate solution based on the size of our house and current energy useage. Thanks to Marshall & McCourt we feel that we have invested wisely for the future.”
Mrs Davison, Stockton
"Great service by Marshall & McCourt! Our new Air Source Heat Pump provides all the heating and hot water we can use. Our house is warm and comfortable. Controlling the UFH is different to conventional radiators but easy to get used to.”
Mr & Mrs Gatenby, Middlesbrough
“Marshall & McCourt gave a very competitive quote and then provided excellent service throughout the installation. We felt that we had been given very good advice throughout and the quality of the finished work was excellent.”
Northdale Horticulture, Northallerton
"Having made the decision to install an air source heating system, Marshall & McCourt were recommended to me and I was impressed by their professional approach from first meeting to completion of the project, which was delivered on-time and within budget.  I would have no hesitation in recommending them in the future."
Mr Davison, Middlesbrough
"Professional service received from start to finish. I would highly recommend them."
Mr & Mrs Rigg, Durham
"Quality product - a Vaillant ecotecplus central heating boiler with 8 year warranty - which was expertly supplied, installed and commissioned by Marshall and McCourt. 1st class service all round."
Mr Simpson, Stockton on Tees
"Marshall & McCourt initially carried out a Green Assessment on our behalf. Being registered with the Government to carry out such an assessment and the recommendation of our knowledgeable builder meant we felt confident to go ahead and install their Vailiant Combi system. The installation went well, so well that we bit the bullet and finally got a combi boiler installed at our adjoining property; getting rid of the old gravity system. Its nice to join the 21st Century with instant heat and water plus programmable timings and, with Marshall & McCourt being an advanced installer, the eight year guarantee gives us peace of mind. Marshall & McCourt are also replacing some latrine piping for us having installed a new towel rail too."
Mr Koeppl , Yarm
“I would just like to say that I would have no hesitation in recommending Marshall & McCourt for any Renewable energy requirements. After receiving various quotes and advice from multiple companies I found Marshall & McCourt to be the most informative, honest and trust worthy. They came up with the perfect system design to suite my requirements within budget. From initial site survey through to completion, the project was handled with great care and attention to detail. The system performs to perfection and was completed with minimum fuss and upheaval in the agreed timescale. I am extremely happy with the overall experience”
Mr Jobling, Rowlands Gill
"I just want to say thanks for the work you and your team carried out for us. After becoming completely disillusioned with the many "experts" who either did not turn up or clearly did not know what they were selling, it was a relief and a pleasure to find a company which actually knew what it was doing. From the initial schedule of work with detailed drawings and accurate costs, to the team carrying out the work on site led by Gary, it was immediately clear that the work would be completed professionally. You installed a complex system integrating PV, Solar and Biofuel, to a high standard, all within the original budget. The systems all work as per design, giving considerable savings on our overall heating costs. Your additional help and support re the RHI made applying a straightforward and easy process. Given the quality and overall cost of the work you completed for us I would have no hesitation in recommending you and your company."
Mr Parker, Seaton Carew
"Very professional and polite. Good overall work."
Mr Leonard, Yarm
“Had great communications between myself and company when required, Gary, the engineer, was great and knowledgeable who answered any questions I had, very happy with new end results.”
Mr Monkhouse, Nunthorpe
