Welcome to 4i Water Services

Experts in Water Treatment Services

4i Water Services was started by three like-minded people who were passionate about water treatment. Our company founders saw the potential for a British-based business to manufacture Legionella control equipment, which in turn could contribute to companies’ carbon reduction. That vision grew and evolved into what is now a team with broad industry-ready water treatment and plumbing expertise, with experience in providing a range of services to a number of commercial sectors. 
We believe in strong customer relations and exceptional customer service. Our team are like a family, and we strive to be just as available and approachable to our clients.  With 4i Water Services, you will receive a fast, precise, and technically excellent service from our friendly and flexible engineers. Our all-in-house approach means we can respond faster and keep solutions simpler. Learn more about 4i Water Services and how we can help you below.
