South East Water Contact - Phone Numbers, Email Form & Complaints

South East Water Contact Number

The South East Water contact number you need depends on the nature of your enquiry. There are separate lines for billing, water supply issues and out-of-hours emergencies, so calling the right number from the start gets you through to the correct department faster.

South East Water is a water-only supplier, meaning it provides clean drinking water but does not handle wastewater or sewerage services. Before calling, have your South East Water account number ready - it is printed on your bill and speeds up identity checks with the adviser.

How to Speak to a Human at South East Water

When you call the billing line on 0333 000 0001, an automated system will ask whether you know your South East Water account number. If you enter it, you can make a payment, check your balance or set up your bill without speaking to anyone. To reach a human adviser, simply wait about five seconds after the last automated option is read out.

The system will then offer four more options - change of address, billing enquiry, water supply issue, or "everything else". Whichever you choose, you will be transferred to a live representative who can help with your query directly. Having your account number and property postcode ready will reduce the time spent on identity checks.

The Water Supply Helpline on 0333 000 0002 works slightly differently: it opens with a brief recorded message about any major incidents currently affecting the South East Water supply area. Stay on the line after the message to speak to an adviser about a specific supply issue or to report a problem.

South East Water Emergency Contact Number

The South East Water emergency number is 0333 000 0365, staffed 24 hours a day, 7 days a week including bank holidays. Use this line for burst pipes, no water, visible leaks on public land and any contamination of your clean water supply. You do not need to be a South East Water customer to report an issue on the public network.

Because South East Water only supplies clean water, wastewater emergencies - such as sewer flooding or blocked drains - must be reported to your wastewater provider instead. Depending on your location, this will be either Southern Water or Thames Water.

You will only receive one bill for both clean water and wastewater, as South East Water bills on behalf of Southern Water or Thames Water.

Request a Free Callback from South East Water

If you would rather not wait on hold, South East Water offers a free callback service through its website. You can book a slot without logging in - just provide your contact number (mobile or landline), an email address and optionally your account number. South East Water will then call you back during your chosen time window.

There are five weekday slots and two Saturday slots available. If a slot does not appear on the booking page, it means it is already fully booked and you should choose from the remaining options. We recommend booking the earliest available slot if your query is time-sensitive.

Callback slots are subject to availability. Fully booked slots will not appear on the booking page.

South East Water Email & Contact Form

South East Water does not publish a direct email address. For non-urgent enquiries, customers must use the online contact form on the South East Water website. You can submit the form as a guest without logging in, and it covers a wide range of topics including billing, moving home, payment plans, water quality and the Priority Service Register.

Once South East Water processes your form, they will reply by email - effectively creating a South East Water email address you can then use for ongoing correspondence about your case. There is also no live chat facility, so the contact form or phone remain the only direct routes to an adviser.

South East Water Bill Support & Financial Help

If you are struggling to pay your water bill or your usage is higher than normal, South East Water has a dedicated bill support line on 0333 000 2468 with specially trained advisers. Several schemes are available to reduce your bill or spread payments, and you do not need to be in arrears to apply.

South East Water offers the following support schemes for eligible customers:

• Social Tariff - a reduced rate for customers on low incomes or certain benefits
• WaterSure Scheme - caps your bill if you have a water meter and meet the eligibility criteria
• Water Direct - payments taken directly from benefits to clear arrears
• Helping Hand Scheme - grants to write off debt for customers in financial hardship
• Single Room Tariff - a reduced charge for single occupants in unmetered properties

If you think you might be eligible, we recommend calling the dedicated support number rather than the general billing line, as the advisers are specifically trained to assess your situation and match you to the right scheme. You can also learn more about bill reduction options in our guide to the average UK water bill.

South East Water Contact for Water Meters

South East Water has some of the highest average water bills in England (around £221 a year), so switching to a meter can make a real difference. Most UK water customers without a meter are billed on rateable value - a property assessment from before 1990 - which means they may be paying for more water than they actually use.

You can request a free water meter installation from South East Water by calling 0333 000 0001 or by filling out the application form on their website. Once installed, you simply submit a water meter reading each month to ensure your bill reflects your actual usage. There is also the possibility of getting a smart water meter that sends readings automatically.

South East Water Leak & Incident Updates

South East Water provides a live incident map where you can check the status of reported leaks, maintenance work and supply interruptions in your area. You can browse the map or search by postcode to find incidents near your property, and each report includes the incident type, status, description and estimated completion time.

You can also sign up for future incident notifications by email or SMS text message. Use the "Keep Me Informed" feature on the map page, enter your postcode and contact details, and choose an alert radius between 200m and 500m. We recommend enabling the Advanced Options so you can widen the alert area and give your alert a custom name for easy management.

How to Make a Complaint to South East Water

South East Water follows a structured four-step complaints process. Since you cannot switch water supplier, the process is designed to escalate your issue through independent bodies if the company fails to resolve it. We recommend starting with a phone call or the online complaints form and keeping a written record of every interaction.

In your initial complaint, include two clear paragraphs: the first detailing the issue and the second explaining what you would like South East Water to do about it. The company will attempt to resolve the matter within 5 working days, and if it takes longer than 10 days, you are entitled to £20 credit on your account.

Write to South East Water

If you prefer to put your query or complaint in writing, you can send a letter to South East Water's registered office. Written correspondence is particularly useful for formal complaints where you want a paper trail, or when you need to enclose supporting documents such as bills or photographic evidence.

The South East Water postal address is:

We recommend sending any complaint letters by recorded delivery so you have proof of receipt, and keeping a copy for your own records in case you need to escalate to the CCW or WATRS at a later stage.
