I would like to contact the water regulators, who are they?

Several key regulatory bodies oversee the water industry in the UK, ensuring that water companies provide high-quality services at fair prices:

Ofwat

Ofwat: The economic regulator for the water and sewerage sectors in England and Wales. They review water prices and ensure that services are efficient and fairly priced.  

Consumer Council for Water

Consumer Council for Water (CCW): Represents customer interests regarding pricing, service quality, and value for money. They also handle complaints related to water quality.

Environment Agency

The Environment Agency (EA): Oversees water extraction and wastewater treatment standards, ensuring environmental protection.

These regulatory bodies work together to maintain high standards in the water industry. You can find their contact information on their respective websites.
