What Areas Does Severn Trent Water Cover?
Severn Trent Water serves communities south of the Humber Estuary, north of the Bristol Channel, east of Llyn Clywedog and west of Lincolnshire. The supply footprint covers much of the Midlands and parts of mid-Wales, taking in cities such as Birmingham, Coventry, Derby, Leicester, Nottingham, Stoke-on-Trent and Shrewsbury, as well as hundreds of smaller towns and villages in between.
Around seven million people rely on Severn Trent for their drinking water and wastewater services. The company is a private, stock-exchange-listed business, with major institutional shareholders including Deutsche Bank, Singapore's sovereign wealth fund, BlackRock and Chinese state investors. You cannot choose your water supplier in England and Wales - who provides your water is determined purely by your postcode.
If you are not sure whether Severn Trent is your supplier, the quickest way to check is to enter your postcode on the Consumer Council for Water website. Neighbouring regions are served by other companies such as Welsh Water, United Utilities, Yorkshire Water and Anglian Water, so a postcode check avoids calling the wrong company.
Severn Trent Water Contact Number
Most Severn Trent customers get in touch through the main customer services line on 0345 750 0500, which handles bills, meter readings, moving home, direct debits and general account questions. The line is open six days a week and calls are charged at your standard landline or mobile rate, usually included in inclusive minutes bundles.
For anything urgent - no water, a burst main, visible leaks in the street, sewer flooding or contaminated tap water - you should skip the billing line and call the dedicated emergency number instead. Have your account number or full postcode ready before you call, as it is the fastest way for the adviser to pull up your file and confirm your identity.

How Do I Contact Severn Trent Water?
If you would rather not sit on the phone, Severn Trent can also be reached through several digital channels. You can message the customer services team on WhatsApp at 0345 750 0500, through Facebook Messenger, or via direct message on X (formerly Twitter) at @stwater. Social media tends to be the quickest option for short billing or account questions during office hours.
For routine tasks, the My Account portal at stwater.co.uk is usually faster than any phone call: you can submit a meter reading, view bills, pay online, set up a direct debit, change your contact details and tell Severn Trent that you are moving home, all 24 hours a day.
Severn Trent Water Complaints
Formal complaints can be emailed to [email protected]. For written correspondence, or if you need to escalate a case in writing, the postal address for the customer relations team is:
Severn Trent Water Customer Care Team
PO Box 409
Darlington DL1 9WF
Severn Trent aims to resolve most complaints at the first point of contact. If your complaint is still unresolved after 8 weeks, or you receive a deadlock letter sooner, you can escalate it free of charge to the Consumer Council for Water (CCW). For cases CCW cannot settle, the final route is the Water Redress Scheme (WATRS), an independent adjudication service whose decision is binding on Severn Trent.
Severn Trent Water Problems
If your tap is dry, your water pressure has dropped or the street is flooding, Severn Trent's In My Area page on stwater.co.uk is the first place to check. It shows live incidents by postcode and will usually tell you whether Severn Trent is already aware of the problem and when supply is expected to be restored.
Severn Trent operates one of the largest water networks in England and openly reports that it loses over 400 million litres of water per day through leaks across its pipes. On wastewater, the Environment Agency has given Severn Trent a highly rated score for its pollution prevention performance, placing it among the better-performing water companies in England.
Severn Trent Water: No Water at Home
Before calling the emergency line, check whether your neighbours have water too. If they do, the problem is likely inside your own property and Severn Trent will not be able to help - it is a job for a plumber. If nobody on your street has water, report it straight away on 0800 783 4444.
If only your own home is affected, try restoring the supply yourself with these three steps:
- Locate the internal stop tap, usually near the water meter under the kitchen sink or in a utility cupboard.
- Turn it counterclockwise (anti-clockwise) fully open to release the flow.
- Run a cold tap for a minute to verify that water has returned and to flush the pipes.
Severn Trent Water Login
The Severn Trent online portal lets you manage your water account without picking up the phone.

If the reset email does not arrive, check your spam folder and confirm your email address is still up to date. If the problem persists, call customer services on 0345 750 0500 and an adviser can reset your account manually.
Severn Trent Water Meter
Severn Trent customers can hold either a metered or an unmetered account. On a metered tariff you pay only for the water you actually use, plus standing charges; on an unmetered tariff you pay a fixed yearly sum based on the rateable value of your property. Metered customers are encouraged to submit monthly readings for more accurate bills.
If you are not sure which type of account you are on, look at the front of your latest Severn Trent bill - it will clearly show either a meter reading and volume of water used, or a rateable value figure.
Is a Water Meter Cheaper?
Whether a water meter saves you money depends on household size and usage patterns. As a rough rule of thumb, if there are fewer people in your home than bedrooms - for example, a couple in a three-bedroom house - a meter is usually cheaper because your consumption is lower than the rateable-value assumption. Larger families with high usage often end up paying more on a meter.
Before switching, use the free Consumer Council for Water online calculator to compare your likely metered bill against your current unmetered charge. Severn Trent also offers a 24-month trial period after a meter is installed, during which you can switch back to your previous rateable-value tariff if the meter turns out to be more expensive.
How Does Severn Trent Read My Water Meter?
Severn Trent reads customer meters every six months. The meter reader matches the black digits on the dial against the meter serial number on file, so between visits you are free to submit your own readings - monthly submissions give a much more accurate consumption record than the twice-yearly manual reads.
The meter measures your water use in cubic metres (1m³ = 1,000 litres). Severn Trent calculates your usage by subtracting the previous reading from the current one and multiplying by the unit rate on your tariff, then adds the fixed standing charge for water and sewerage.
Can I Have My Severn Trent Water Meter Removed?
Severn Trent does not physically remove installed water meters. However, if the meter is making your bills more expensive, you can ask to switch back to an assessed or rateable-value charge within the 24-month trial window that follows installation; Severn Trent will then bill you on a fixed yearly amount based on property size and rateable value rather than metered consumption.
Severn Trent Water Moving House
You should tell Severn Trent about a house move no more than 28 days before your moving date. Doing it sooner risks the change being missed; leaving it until after you have moved means you could be charged for water used by the new occupants. The Moving Home form on stwater.co.uk is the quickest way to handle it.
There are three scenarios to be aware of, depending on where you are moving:
Moving within the Severn Trent area
Log in to your existing account online and update your address details. Your account stays open and simply follows you to the new property.
First-time move into the area
Open a new account, providing your new address and the details of the previous occupant so Severn Trent can close their account cleanly.
Moving outside the supply area
Request account closure online, provide a forwarding address and - if metered - a final reading so your closing bill is accurate.
Hard water note
Like most of England, Severn Trent supplies hard water due to the high mineral content of its sources. Expect limescale in kettles and appliances.
If you are setting up utilities for the first time and not sure where to start, our guide to UK water suppliers walks through how water billing works, who supplies which region and what to do on move-in day.
Severn Trent Water Bill
Every Severn Trent bill contains the same core information on the front page, whether you are metered or unmetered. It is worth knowing where to look so you can check a charge in seconds rather than wading through the whole document.
- Bill balance and due date - the amount to pay and the deadline.
- Payment details - for direct debit customers, the final digits of the bank account and sort code the payment will be collected from.
- Previous payment history - what you have paid over the last billing cycle.
- Fresh and waste water breakdown - how much of your bill is for drinking water versus sewerage and drainage.
The format of the bill differs for metered versus unmetered accounts: metered bills show the opening and closing meter reading, the volume used in cubic metres and the unit rate, while unmetered bills show the rateable value and the fixed annual charge. The reverse of the bill shows prior bill amounts and consumption details so you can track how your usage is trending over time.
