A few useful answers
Common questions
Who supplies water in the WS postcode area?
Severn Trent and South Staffs Water supply parts of the WS postcode area. The supplier is decided by where the property is, not by who lived there before you.
Can I switch water supplier in WS?
No. Household water supply is not a competitive market anywhere in the UK — there is one supplier for each address and no tariff to compare. What you can change is how you are charged, by asking for a meter.
Why does this page list more than one company for WS?
A postcode area can straddle a boundary, and in much of England the company that supplies the taps is not the one that takes the waste water away. Both appear here so you can check which applies to your address.
Do I need to open a water account when I move in?
Yes. Tell the supplier the day your tenancy starts and give an opening meter reading if the property has a meter, so you are not billed for what the last tenant used.
Where to confirm this
We hold the supplier at postcode-area level, which is coarse enough to be wrong at a boundary. These are the industry's own sources, and they settle it for a specific address.
