Frequently asked questions

Why do I have no water or low pressure?

The problem affects your neighbours
If you have problems with your water pressure, and your neighbours do too, it is probably related to a problem in your area. Call customer services for advice.

The problem doesn’t affect your neighbours
If the problem only affects you and not your neighbours, especially if you’ve had plumbing work done recently, it is likely to be a problem with your building. You will need to call a plumber.

Only the upstairs taps are affected
If your cold tap downstairs closest to the stop tap is working properly, but you are experiencing a loss of pressure or no water supply upstairs, it usually means there is a problem with the water pressure. Call customer services for advice.

Only the hot water is affected
If the problem only affects your hot water supply, but your cold water is working normally, the problem is probably related to your building, and you will need to call a plumber.

Some things to check

Sometimes, problems with water supply are caused by a problem in or near your building. Try doing the following:

• Check that your stop tap is turned on.
• Ask your neighbours if they have recently carried out any plumbing work that may have affected a communal water pipe.
• If the weather is very cold, make sure your pipes have not frozen.

What should I do if my tap water discoloured?

Causes of discoloured water
If your tap water looks murky, with a black, brown, orange or yellow discolouration, there could be a number of possible causes. Reasons for discoloured tap water include a burst water pipe or ageing plumbing.

How to fix it
If the problem lasts for more than one hour and also affects your neighbour’s tap water, Severn Trent Water recommends running the cold tap in the kitchen at a steady rate for about twenty minutes until the water runs clear.

If the water is still discoloured, turn the tap off, wait for twenty minutes, and then run the cold tap again for another twenty minutes. If the water still does not run clear, call the Severn Trent phone number for advice.

Why is my water cloudy?

Small air bubbles in your water can make it appear cloudy, milky or grey. This is usually caused by nearby repair works or faulty pipes in your building. If it doesn’t clear up by itself soon, contact Severn Trent customer services.

Is Severn Trent my water company?

Severn Trent Water is in charge of water supply and waste water treatment for houses across the Midlands and some parts of Wales.
If you’ve recently moved house and you live on the border of this region, you may not be sure who your water company is. Call Severn Trent Water contact number for advice.

I have a special medical condition – what should I do?

Some customers have a medical condition that could be affected by interruptions to their water supply, such as customers who use a dialysis machine at home.

Pre-planned water works
Make sure you inform the customer service representative at the Severn Trent Water number about any medical needs that you have. This will allow Severn Trent to inform you in advance of any pre-planned works in your area that may lower water pressure or shut-off your water supply.

Severn Trent can also try to contact you to discuss what time water works would cause you the least disruption.

Emergency water works
In some situations, such as a burst main, Severn Trent will not be able to inform you in advance of works. However, they will try to keep you informed of developments and may provide you with an alternative water supply in the meantime.

About Severn Trent Water

Severn Trent Water is a water company that supplies water and manages waste water to some parts of England and Wales. It takes its name from the two major rivers that run through its catchment area, the River Severn and the River Trent.

If you live in England or Wales, your water company is assigned to you based upon where you live. Severn Trent Water customers live in the Midlands of England and some parts of Wales.

During the 18th Century, there were hundreds of companies and local government bodies that were responsible for different aspects of managing water, including water supply, sewage and river pollution.

Regional Water Authorities

By the 19th Century, many of these companies were purchased by local councils. Then, under the 1973 Water Act, the various bodies were grouped together according to their location, forming ten regional water authorities.


Severn Trent Water Authority was one of the ten water authorities. It was owned by the government until 1989, when it was transferred into private ownership and began operating under the name Severn Trent Plc, the parent company of a number of companies including Severn Trent Water and Severn Trent Services.
Severn Trent now supplies water to around 3.8 million customers in the Midlands of England and some parts of Wales.
