We only supply the fresh stuff. So although we bill on their behalf, your waste water services will be provided by either Thames Water, Southern Water, Severn Trent Connect or Icosa water, depending on where you live.
To find out who your waste water supplier is, pop your postcode into Water UK's website(opens in a new tab).
If you're a 'One Bill' customer, see our FAQs on how your bill is worked out here.
