Water only
Portsmouth Water
Supplies drinking water to Portsmouth, Havant and parts of south-east Hampshire and West Sussex. Southern Water takes the waste water away.
Setting the account up when you move in
- Tell Portsmouth Water the day your tenancy starts, so the bill is in your name from that date and not the last tenant's.
- If the property has a water meter, send an opening reading the day you move in. Photograph the whole display — that photograph is what settles a disputed opening bill.
- A second company takes the waste water away. It often collects both charges on one bill, so check which company that bill is actually from before you set up a second payment.
- There is nothing to compare and no supplier to switch to. What you can ask for is a meter, which changes how you are charged rather than who charges you.

It may supply addresses in the PO, SO postcode areas. Several of those are shared with another company, so the postcode area page is the place to check yours.
Does Portsmouth Water take waste water away as well?
No. Portsmouth Water supplies the drinking water only. A separate company takes the waste water away, and it often collects the charge for both on one bill.
