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 wholeheartedly recommend them and would have no hesitation in using them again.

Really good professional service. Came down and provided us with a quotation. Pencilled in a fitting date. No messing about. Two fitters came on the day and fitted a new boiler within the day.
Great service.

The guys at NCS were brilliant. We had a new boiler installed and I cannot fault their work. Not to mention the office staff, who kept us up to date with the whole process from start to finish and were very friendly and knowledgeable. Would highly recommend.
