South West Water Problems


If you have a complaint about South West Water problems, you can start the complaint procedure to get it resolved. Unfortunately, you can’t switch water suppliers so you will have to be patient and allow the South West Water complaints team to deal with your problem. 

Fortunately, you can follow these 4 steps to get your South West Water complaint solved as quickly as possible.

South West Water Problems: Step 1

The first step is to use one of the South West Water contact methods to communicate your issue. Should explain your problem and let the agent walk you through the process.

If you need to complain about the same issue within 12 weeks, South West Water recommends that you make the complaint in writing. If you are writing a complaint, remember to include two paragraphs. The first paragraph should include what the issue is, and the second should explain what you want South Water to do about it.

South West Water Problems: Step 2

If you have still not received a reply or you are unsatisfied, South West Water will escalate your complaint to a manager to review the issue and set out what must be done to resolve it.


South West Water Problems: Step 3

If you have not heard anything from South West Water within 8 weeks or you are still dissatisfied with their response, you can take your complaint up with the Consumer Council for Water (CCW). The CCW is an official body that deals with water complaints after a water company has failed.

South West Water Problems: Step 4

If the CCW fails you or your complaint becomes a long-term dispute, it can be referred to the Water Redress Scheme (WATRS). This is the last resort when it comes to water disputes and you must have gone through all previous steps beforehand.

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. The CCW is the correct body.

South West Water Meter


The Environment Agency has identified South West Water as a water-stressed area as of 2021. When a region is water-stressed, this means that the household demand for water is a high proportion of the rainfall. The Isles of Scilly that is supplied by South West Water is a water-stressed area.

In order to help save on water usage and avoid leakages that can lose a lot of water, South West Water has been asked to consider compulsory water meter installations in people’s homes. This means a customer would send a regular water meter reading to South West Water to measure how much water they are using.

Some water suppliers like Thames Water already do this, supplying smart water meters to send automatic meter readings.
