Couldn't have asked for a better service!
Customer Service
Excellent service - a very quick response to my initial inquiry, swiftly followed up with a survey and quotation. Installation took place on the agreed date and the team were very helfpul and friendly. Everything was left very tidy. Couldn't really have asked for a better experience.

Domestic oil fired boiler replacement
Customer Service
It has taken this company just over four weeks following my enquiry over an oil fired boiler replacement, to inspect, advise and provide a detailed written quotation, then to install. This was not an easy installation but superbly dealt with, and left so neat and tidy. An impeccable service all of which could not have been more helpful, courteous and professional. It has been a pleasure to deal with all concerned and I am a one hundred percent satisfied customer.

Highly Recommend
Customer Service
NCS were brilliant from start to finish. From the initial survey, to helping me get additional funding and throughout the installation of a new oil boiler and water tank the communication was great, the admin support fab (no hanging on hold for hours on end) and the engineers worked efficiently, professionally and with consideration for the minor disruption caused. I certainly won’t hesitate to recommend.

Installation of new combi boiler and associated pipe work
Customer Service
I used NCS to install a new combi boiler after my old boiler had broken. Martin arrived promptly to give a thorough survey of my house. He suggested the best solution to replace the old heating system, taking into account the age of the property and limited space available. The quote arrived the same day, and I was happy to go ahead with the work. The fitters, Richard and Tony, were amazing! They arrived punctually, worked efficiently and completed the job on time. They were always cheerful and cleaned up everything. Great service throughout including communication from the office. Thank you!

Really impressed with NCS
Customer Service
Really impressed with NCS from the quote right through to the installation of my new oil boiler and the aftercare follow up. I was kept informed the whole way through and the team at NCS did a great job with the installation and left the place immaculate.

Boiler installation
Customer Service
The boiler was installed well and to an agreed price. The work was, however, considerably less than originally quoted. The company agreed to install a new tap free of charge. They sent two engineers, one of whom went at 11am. I was told the remaining engineer, who left at 4pm, didn't have time to install the tap and the company then said that they wanted an additional 2 hour call out charge to do the work, even though the on line video would suggest its a 10 minute job.

Hello, Thank you for your review. We have reviewed all files and notes for your job and can confirm that we did carry out all works that were quoted for. Our original estimate did not include installation of a tap. However, we can see it was agreed that if the engineer had time whilst on site, he would change the tap for you at no additional cost as a gesture of good will. This was never guaranteed and was always subject to timing. Unfortunately, it was not as straight forward as first anticipated and we apologise that the engineer did not have time to complete this for you. On the day of installation, we sent one engineer and assistance to complete the works. Our work schedule allows for one engineer to be on site to carry out all necessary works quoted for with assistance when required throughout the day. We are sorry to hear that you are not completely satisfied with the service as we always aim for complete customer satisfaction. If you wish to discuss this further then please do not hesitate to contact us. Regards
Oil Fired Boiler replacement - professional work in specified time
Customer Service
NCS have been prompt, professional and extremely helpful in responding to all queries I made between the initial site survey and completing the work. All questions answered promptly with good, clear supporting explanations. I had site surveys carried out by 5 potential suppliers/installers, 1 could not do the work as they had misunderstood and only worked with Gas boilers, this despite advising it was an Oil Fired installation. 1, sadly a common occurrence these days, spent 45 minutes on site, explained how they would do the work and then never quoted. 1 never provided a Quote or answered some questions I had. The only other one to actually Quote initially did not provide an "apples for apples" comparison, that I had requested, for two manufacturers, on querying they corrected and although also prompt and professional, were ultimately more expensive, even for their preferred manufacturer and had shorter warranty period.

Excellent service from enquiry to installation
Customer Service
My experience of NCS has been absolutely amazing. From my first enquiry, followed by a survey, then response to my queries and finally the installation was superb. The whole team were so very friendly, knowledgeable and supportive. It is always a worry when appointing a contractor for something as big as a boiler installation but from the outset I felt comfortable with NCS and this confidence continued through all steps. I would whole heartedly recommend them and would have no hesitation in using them again.
