I have used the services of C.S.Boxall for many years. I have always been very happy with the work that they have done for me. Paul, the engineer who currently carries out work on behalf of the company is very efficient, always punctual and is a very cheerful and polite young man. I would have no hesitation in recommending C.S.Boxall


Fantastic service received at our workplace. Inspection of the system made, recommendations made and quote provided in a very efficient manner. Staff are friendly, polite and a real credit to the company. They worked around our staff in busy offices causing little disruption. Work was of a high standard and after they left you would have never known they had been. Many thanks for a great job.


I can’t recommend highly enough they came to quote and actually listened to what we wanted, they made suggestions based on their extensive knowledge on the options available. The work was carried out to an exceptionally high standard and ahead of schedule the team were polite/punctual/tidy & knowledgeable. I wouldn’t hesitate to recommend and I look forward to using them again for more work next year!


Very impressed with CS Boxall. First time using this company and from my initial call with the staff in the office, to the visit of the engineer, I couldn’t have asked for a better service.

Every person was friendly and efficient and I would really recommend using them!

Thanks again CS Boxall, for keeping my family warm and so promptly!!
