SES Water serves over 280,000 homes across a water supply area that spans parts of east Surrey, West Sussex, West Kent and even South London. Read on to find out more about how to contact SES, pay an SES water bill, and how the SES moving home process works.

SES Water is a water only supplier in the South East. Since SES Water only supplies clean drinking water, SES Water customers will be billed by Southern Water for their sewerage and wastewater services, however this will appear on the same bill.

SES Water is headquartered in Redhill and is currently owned by two Japanese utility and trading companies, the Sumitomo Corporation and the Osaka Gas Company.

If you’re unsure that SES is your water supplier, check out our Water Supplier List to find out who supplies your region.

What does SES stand for? SES stands for Sutton and East Surrey. The acronym became the company’s name when it was rebranded as SES Water in 2017. SES Water was the product of a merger between the East Surrey Water Company and Sutton District Water in 1996.

SES Water Moving Home


If you’re moving home, you will need to let SES Water know what’s going on so they can charge you the right amount on your water bill. You will need to give the SES Water moving home team at least 2 working days notice before your move so you can avoid being incorrectly charged and process the request as soon as possible.

Before calling the SES Water contact number, you need to consider what your SES Water moving home situation is:

  1. Existing customer - changing address within the SES Water supply area
  2. Existing customer - moving out of the SES Water supply area
  3. New customer - moving into the SES Water supply area from another water supplier

SES Water Change of Address

If your SES Water moving home situation is just a simple change of address in the SES Water supply area, then you will still need to fill out the Moving Within Our Area online form. If you don’t complete this at least 2 days before your moving date, you may be liable for:

  1. The day the water meter was last read will be used to calculate the water charges
  2. The day another customers tells SES Water they have become the new occupier
  3. The day SES Water finds out about the change

You can also do a change of address by calling the SES Water contact number for billing enquiries 0173 777 2000.

SES Water Close Account

If you are moving out of the SES Water supply area to another part of the UK, you will need to close your SES Water account. As with the change of address process, you should let SES Water know at least 2 days before to avoid unnecessary charges.

If you are moving out of the area, be sure you take a last water meter reading to make sure your water bill is accurate.

SES Water New Customer

If you are a new SES Water customer, you will need to set up your SES Water account so you can begin paying your water bills. 

You should contact SES Water as soon as you move in to make sure you are paying the right amount for your water. You can set up a new account either online via the New Customer form or by calling the customer service SES Water contact number 0173 777 2000.


To set up your new SES Water account, you will need to provide:

  1. First name and surname
  2. Address & postcode
  3. Email address
  4. Water meter reading
  5. Payment details

Once this is all set up, you will start paying SES Water with the contact method of your choice.

Is SES Water a hard water area? Like most of England, SES Water supplies hard water to its customers. This is due to the higher concentration of minerals in the drinking water. To find out more about how to handle hard water, check out our Water Hardness guide.

SES Water Pay Bill


Since everyone’s finances are different, finding the right payment method for your bills is key for making sure you’re both comfortable and able to make your payments on time to avoid getting into debt. There are a number of SES Water pay bill options available so you can find the most convenient one for you.

SES Water Direct Debit

The simplest way to pay your SES Water bill is to set up a direct debit. When you call the SES Water contact number to set up a new SES Water account, you will be able to set up your direct debit there and then with the SES Water billing team. With a direct debit, you won’t have to worry about remembering to pay your water bill as it will come out of your account automatically.

SES Water Pay Bill by Phone

If you prefer to make your SES Water payment over the phone, just call the automated payments number on 0800 587 2936 where you can pay either by debit or credit card. You can even find out your account balance to check to see if you owe any money. All you need to have handy is your SES Water bill and your customer reference number.

SES Water Pay Bill by Cheque or Postal Order

If you prefer to pay your water bill via a cheque or a postal order, you can do so by making a cheque payable to the following address:

SES Water
London Road

Make sure you write your customer reference number on the back of the cheque and include the payslip at the bottom of your SES Water bill before sending it to SES Water.

SES Pay Bill at PayPoint or Post Office


Few customers realise they can also pay their water bill at a PayPoint or at the Post Office like you can with your energy bills. You can request an SES Water payment card from SES Water when you sign up as a new customer or if you want to change your payment method.

You can pay your SES Water bill using cash at any PayPoint location with your SES Water payment card, or you can pay it at the Post Office. Make sure to bring your water bill with your payment card so you can complete your payment.

Be aware that the post office will charge you a fee and you should always ask for a receipt.

SES Water Pay Bill at the Bank

You can take your SES Water bill to your bank or building society to make a payment instead of the post office. You should be aware that some financial institutions may charge a fee to process your payment, however at NatWest you can pay for free provided the branch is in the SES Water supply area.

SES Water Pay Bill via Online Banking

You can also use online banking methods to make your SES Water bill payment. You can do this through a standing order or a BACS. Make sure you fill in the right amount for your payment and fill in SES Water’s correct bank details:

  1. Sort Code: 57-00-76
  2. Account Number: 00000000 (eight zeros)
  3. International Bank Account Number (IBAN): GB28NWBK60000139608956 or;
  4. Swift Code: NWBKGB2L

SES Water Charges


SES Water charges and water rates for your water bill vary depending on what type of property you live in and your water use habits. Most importantly, your water rates from SES Water will depend on whether you live in an unmetered or metered property.

SES Water Unmetered Customers

If your property does not have a water meter, you will pay for your SES Water bill based on your house’s rateable value. This means that you will be charged a fixed rate based on your property’s size, condition, and age. This is beneficial for those customers who have large households.

What is Rateable Value? Rateable Value was the way that council rates were calculated prior to 1990. Although this is no longer used, water companies still base their charges off of rateable value. Rateable value is calculated via an assessment of a property’s condition, age, and size.

SES Water Metered Customers

If you have either a traditional water meter or a smart water meter fitted, your water bill will be based on your usage. We recommend you send a water meter reading every month to make sure you are paying the right amount every month.

Standing Water Charges

Along with your normal water rates, you will be charged a standing charge by SES Water that pays for the use of the SES Water connection to your house. This is similar to a standing charge with your energy rates.

SES Water Problems


If you have a complaint with SES Water, there is a complaints procedure in place so you can get your issue as resolved as quickly as possible. Unfortunately, you can’t switch water suppliers, so you will have to be patient and allow SES Water to help you.

Here we’ve broken down the SES Water complaints procedure into 4 easy steps to help you:

SES Water Complaints: Step 1

If you have an issue with your water supply or you have no water in the house, get in contact with SES Water as soon as possible. 

You can either contact them by calling them on their billing enquiries number 0173 777 2000 or by filling out the SES Water feedback form. You can also write to SES Water by letter. Make sure you include your customer reference number when either writing or calling.

SES Water will try to resolve your issue within 10 working days.

SES Water Complaints: Step 2


If your complaint has still not been resolved, SES Water may escalate it to a manager to handle it for you. You should give them at least 8 weeks to get to you before taking the next step.

SES Water Complaints: Step 3

If SES Water still hasn't managed to resolve your complaint or you are not happy with the result, you can take your complaint to the Consumer Council for Water (CCW). The CCW is an official body that works like the water ombudsman.

SES Water Complaints: Step 4

If the CCW fails to resolve your complaint adequately, then you can escalate it even further to the Water Redress Scheme (WATRS). WATRS only deals with long-term disputes and it should be the very last resort for your water complaint. It is unlikely that you’ll need to go to WATRS, but it is there if you need it.

Don’t take your complaint to Ofwat! If you have a complaint, do not take it to the water regulator Ofwat as they will be unable to help you. Ofwat only deals with anti-competitive behaviour in the water industry and does not deal with the individual complaints against water suppliers.

SES Water for Business

SES Water for Business is specifically for commercial customers who need water services for their business. Commercial customers have the same SES Water contact number as residential customers on 0173 777 2000. There is also a dedicated email address for business developer customers [email protected].

SES Water E Coli Issue in 2021


On the 7th October 2021, there were reports that the E. coli bacteria had inflected the water supply for almost 400 postcode areas in the SES Water supply area. Customers were advised to boil their water before using it. In a statement, SES Water said:

Our customers in and around Oxted are being advised to boil their tap water after tests showed that water supplies could be affected by the bacteria E-coli

By the next day however SES Water tweeted that the boil notice had been lifted with immediate effect.
