The County Durham-headquartered group is the only company in the Water & Sewerage Utility category to be added to this year’s World’s Most Ethical Company® list.
It is also just one of four UK-based companies and 130 companies worldwide recognised in the 2016 list by the Ethisphere Institute.
Heidi Mottram, chief executive officer, said: “Since 2002, we have given back more than 100,000 hours to local communities through our employee volunteering scheme.
“Customers trust us to provide our services that they rely on every day in their homes and businesses.
“We take the responsibility of building and maintaining that trust very seriously, conducting our business in a way that minimises environmental impact, promotes positive interaction with the community and is conducted with sound ethical standards.
“Our ethical track record is testament to all our 3,000 people across the business who make ethical behaviour a standard business practice.”
Ethisphere’s chief executive officer, Timothy Erblich, added: “Northumbrian Water Group sets a clear example of ethical and sustainable business practices and stakes their reputation on their ability to provide a safe and sustainable water supply.”
“Their values align with our mission to improve the world in which we live. Congratulations to everyone at Northumbrian Water Group for being recognised as a 2016 World’s Most Ethical Company.”
