Wastewater only bills
Your water might be supplied by a separate company. If so, we'll only bill you for wastewater.
For more information on who supplies your water and wastewater services, please use our postcode checker or see our area of operation map at the bottom of the page.

Affinity Water
We share around 70,000 customers with Affinity Water in the Folkestone and Dover area.
The following information will help customers who receive water supply charges from Affinity Water and wastewater charges from us.
Why do I receive bills from two water companies?
You receive two bills because the water and wastewater services to your property are supplied by two different companies, Affinity Water for water services and Southern Water for wastewater services.
Affinity Water provides us with all the information we need to bill your metered wastewater charges.
If my water company installs a meter, how will this affect my wastewater charges?
Your water company will provide us with the meter details and we'll base our charges on the readings provided.
We can't meter the water that returns to the sewer for treatment because not all the water you use returns to the sewer. We've assessed the typical percentage return as 92.5% and so we bill based on a 'standard return to sewer' of this amount.
This means that for every 100 cubic metres supplied, we'll bill for 92.5 cubic metre.
Who should I contact if I've a problem with the meter or the meter readings look high?
Please contact Affinity Water. If there are any problems with the meter that requires a change to your bill, we will be notified automatically.
How do you charge if I cannot have a meter?
If it's not possible to meter your water supply, you will switch from paying unmetered charges to paying assessed charges. These are calculated in various ways, for example the number of bedrooms in your home or on single occupancy.
Where a wastewater-only customer is placed on an assessed measured charge for water services, we'll also switch that customer to assessed wastewater charges.
In this situation, we use Affinity Water's method of assessment to calculate our wastewater charges.
Each independent water company has its own method of calculating assessed measured charges and therefore our wastewater charges reflect those differences.
If the number of occupants in your property changes, please contact Affinity Water, who'll inform us.
The table below shows our charges for 2023-24 (1st April 2023 to 31st March 2024) and 2024-25 (1st April 2024 to 31st March 2025) for your area.

The following information is designed to help customers who receive water bills from South East Water.
Why do I receive one bill from South East Water if Southern Water provides my wastewater service?
Many of you told us getting a bill from South East Water for your household drinking water, and another one from Southern Water for your wastewater services was frustrating. So we teamed up with South East Water to launch 'One Bill' – a single bill from South East Water that also includes our charges too.
Designed to make things simpler for our shared customers, One Bill means you only need to contact one company – South East Water – to make payments for both of the services you receive.
If my water company installs a meter, how will this affect my wastewater charges?
Your water company will provide us with the meter details and we'll base our charges on the readings provided.
We can't meter the water that returns to the sewer for treatment because not all the water you use returns to the sewer. We've assessed the typical percentage return as 92.5 per cent and so we bill based on a 'standard return to sewer' of this amount.
