The Affinity Water group is ultimately controlled by a consortium of long-term investors comprising the Allianz Group, HICL (managed by InfraRed Capital Partners) and DIF.

Our zero harm commitment

We are committed to creating a working environment to achieve zero harm and improved well-being.

We believe all injuries are preventable and nothing is so important we cannot take the time to do it safely.

We recognise that nothing is more important than supplying drinking water to our customers, and doing it in a safe manner, without injuries to our teams, to contractors, to members of the public. Our Safety and Health policy gives everyone clear basic guidance on their health and safety responsibilities at every level within our business.
