About Us

Following the water market opening in April 2017, Affinity for Business split from the wholesaler, Affinity Water, to become an independent clean and waste water retailer. Based in Welwyn Garden City, Affinity for Business specifically services businesses across the UK for both clean and waste water needs.

50,000+ commercial customers already rely on Affinity for Business to take care of their water. For some of those, water is a critical element in the operation of their business. For others, it’s something they need to provide a comfortable working environment. However, every business relies on it being there when they need it.

How can we help?


Customer service is where we’ve made our name, which is why your water supply is looked after by an experienced Account Manager. We also have a wide range of additional support and efficiency services to help you save money and get more from your water.


We work closely with water wholesalers to make sure that any issues or interruption to your service is resolved in the minimum time.


We provide transparency in your usage and billing. Our approach is simple – easy-to-read bills that contain accurate information based on actual meter reads. If you need more granular data or wider support services, we can deliver these too.


From water efficiency audits to working with trusted partners to install more water efficient technology and equipment, we can help you make economic and ecological savings.
