Is Severn Trent legit?

Legit

If your water comes from Severn Trent, you are with a real, long-established supplier, though your bill can look very different once a meter goes in. Metered charges follow what you actually use rather than your home's rateable value, so heavy use or a hidden leak inside the property shows up on the bill.

What we checked

  • Privatised in 1989
  • Head office in Coventry
  • Listed on the London Stock Exchange
  • Ratings on other review websites: 5/5

Watch out for

  • A phone call claiming your water will be cut off tomorrow over an unpaid bill.
  • A caller at the door saying the supply must be shut off and asking you to fill a basin.
  • A move onto a metered bill you did not ask for, under trials that switch some homes automatically.

Did your Severn Trent bill jump after metering?

We help you write it, it gets its own public page, and you can have it sent to Severn Trent as a formal letter.

How do I contact Severn Trent customer service?

The Severn Trent customer service number is 0345 7500 500, and the customer care team also takes email at customercare@severntrent.co.uk. Severn Trent says calling is the quickest way to raise a problem, and its complaints process page, linked in the details at the top of this page, sets out how a complaint is handled. A leak, a burst main or no water at all goes through the emergency route on the Severn Trent website rather than the complaints process. Have your account number, the property address and a current meter reading ready, and ask for a reference number for every contact.

Bill or repair you want put right? Start your complaint here too, and we push it out to Severn Trent by email, social media and printed letters.

How do I escalate a complaint with Severn Trent?

To escalate a complaint with Severn Trent, use the second stage of its own complaints process: if you are not satisfied with the first response from the customer care team, ask for your complaint to be reviewed. Put that request in writing, quoting your account number and complaint reference, what has gone wrong, the dates of earlier contacts and what you want, such as a corrected bill, a repair, a refund or a goodwill payment. Severn Trent's head office is in Coventry.

Why is my Severn Trent bill so high?

A Severn Trent bill that is higher than expected usually comes down to one of a few causes: an estimated reading instead of an actual one, a leak on the supply pipe or inside the property, more people or appliances using water, the yearly price change, or charges carried over from a previous address or occupier. Check whether the reading on the bill is marked as estimated, read the meter yourself, photograph it with the date showing and compare the two.

If you are not on a meter, the bill is based on the property rather than on what you use, so ask Severn Trent whether a meter would suit your household. If you think you have been overcharged, ask Severn Trent in writing to correct the bill and refund any overpayment, quoting your account number.

Can I complain to CCW (Consumer Council for Water) about Severn Trent?

Yes. CCW (Consumer Council for Water) takes up complaints from household customers of water and sewerage companies in England and Wales, and that includes Severn Trent customers in the UK. CCW generally expects Severn Trent to have had the chance to put things right first, so keep a record of every call, email and reference number.

Is that Severn Trent call about cutting off my water real?

Not if it threatens to cut your water off the next morning over an unpaid bill. Severn Trent says it would never cut anyone's supply off out of the blue. People claiming to be from Severn Trent have also called at homes, asked residents to fill a basin while the water was supposedly shut off, and robbed them while they were busy.

What do people complain about most at Severn Trent?

Nothing has been reported about Severn Trent here yet. Our research shows what typically goes wrong at UK water and sewerage companies: bills based on estimated readings, charges that follow a household after a move, leaks and burst pipes that take a long time to repair, low pressure or interruptions to supply, sewer flooding and blocked drains, and discoloured or odd-tasting water.

Sewer flooding at home, or a bill that does not match your meter? Be the first to report it, and your case opens the record for the next household in the Severn Trent region with the same problem.

What happens after I submit my complaint?

And we stay with it after you file. Our trained AI opens a case file for you and keeps coaching: what to reply, when to push again, and how to escalate if nothing happens.

Can other consumers help me with my Severn Trent complaint?

Yes. We have an active community of consumers, and complaints here are public: people who ran into the same problem with Severn Trent can give you advice or back you up with their own story. A complaint with a community behind it is much harder to overlook.
