I have dealt with Acorn Water and Aidan and Bill Holland and Denise Bennett for many years and look forward to doing so for many more. They are capable, efficient and absolutely trustworthy. If they say that they will do something, they do it. Their invoices are always paid on time. They are also personally extraordinarily friendly and pleasant to talk to. I would not hesitate to recommend them.


Just had my water tested, brilliant customer service with a very clear and easy to understand diagnosis. Would definitely recommend


Outstanding customer service, our water was tested and the problems diagnosed and treated with amazing speed. This resulted in improved health and well-being for all the family.
