Can I change my water supplier? This question, which was once unimaginable in the United Kingdom, now promises newfound freedom and control over an essential resource. Historically, the water industry operated as a regional monopoly, leaving consumers with limited or no choice when selecting their water supplier. However, recent changes have transformed the landscape, allowing individuals and businesses to explore the possibility of changing their water suppliers. In this article, we explore the power of choice and the benefits, process, considerations, and challenges associated with water supplier switching in the UK.

1. The Opening of the Water Market

For many years, the water industry in England and Wales operated as regional monopolies, with water companies having exclusive control over their respective regions. However, the market was opened to competition in April 2017, mirroring the liberalization in other utility sectors like energy. This move aimed to foster innovation, drive down prices, and improve customer service by introducing competition and consumer choice.

2. The Benefits of Water Supplier Switching

Enhanced Customer Service

The introduction of competition has compelled water companies to improve their customer service. With the ability to switch suppliers, customers can choose companies that offer better customer support, respond promptly to queries, and prioritize customer satisfaction. This heightened focus on customer service has created a more customer-centric industry where water companies strive to provide exceptional service to retain and attract customers.

Lower Prices

Competition in the water industry has the potential to lower prices for consumers. Water suppliers must now vie for customers, leading to competitive pricing strategies and cost-saving initiatives. By comparing tariffs and services offered by different suppliers, consumers can find better deals and save money on their water bills. The increased competition has also encouraged suppliers to become more efficient in their operations, which can further contribute to price reductions.

Increased Innovation and Efficiency

Competition drives innovation and efficiency. To attract and retain customers, water companies must explore new technologies, practices, and service offerings. This innovation can improve water quality, reduce water wastage, and increase environmental sustainability. The opening of the water market has spurred advancements such as smart metering, leak detection technologies, and water conservation initiatives, benefiting consumers and the environment.

3. The Process of Switching Water Suppliers

Eligibility and Availability

Before switching water suppliers, checking if the property is eligible for switching is important. Most businesses in England and Wales can switch suppliers, while domestic customers may have limited eligibility based on geographical location. Additionally, the availability of different water suppliers may vary depending on the area. It is advisable to consult the Open Water website or contact the existing supplier to determine eligibility and available options.

Research and Comparison

To make an informed decision, research and comparison are key. Consider factors such as tariffs, billing methods, customer service reputation, and additional services offered. Numerous online platforms provide information and comparison tools to simplify evaluating water suppliers. It is also beneficial to seek recommendations from other consumers or businesses who have switched suppliers to gain insights into their experiences.

Notifying the Current and New Supplier

Once a suitable water supplier has been identified, it is essential to inform the current and new suppliers of the switch. This ensures a smooth transition and avoids any disruption to water services. The process typically involves providing relevant information to the new supplier and requesting a switch in service. It is advisable to follow the specific procedures outlined by the water suppliers to facilitate a seamless transfer.

Implementation and Meter Readings

After notifying the suppliers, the new supplier will coordinate the switch and arrange any necessary meter readings. It is crucial to provide accurate meter readings to ensure accurate billing. During the transition, water services should remain uninterrupted, and any billing or meter arrangements changes should be communicated to avoid confusion. Promptly providing the requested information and cooperating with both suppliers can help facilitate a smooth switch.

4. Considerations and Challenges

Geographical Restrictions

While the water market in the UK has opened up, there may still be geographical restrictions on switching suppliers. Some areas might have limited choices, particularly in more remote regions. It is important to check the availability of different suppliers in the desired location before considering a switch. In such cases, engaging in discussions with the existing supplier may be beneficial to explore alternative options or negotiate improved services.

Contractual Obligations

Before switching, reviewing any existing contractual obligations with the current water supplier is important. Some contracts may have minimum contract periods, early termination fees, or specific notice periods. Understanding these obligations can help avoid any unexpected costs or complications. It may be necessary to plan the switch strategically, considering contractual terms to minimize any potential financial or legal implications.

Water Quality and Service Reliability

When switching suppliers, consider the reputation of the new supplier concerning water quality and service reliability. Access to clean and safe water should be a top priority, so researching the new supplier’s track record and customer reviews can help ensure a satisfactory experience. If applicable, engaging in discussions with the supplier or conducting site visits can provide valuable insights into their operations, water treatment processes, and commitment to service excellence.


The liberalization of the water market in the UK has empowered consumers by allowing them to choose their water supplier. This newfound power of choice brings several benefits, including enhanced customer service, potential cost savings, and increased innovation and efficiency in the industry. By understanding the process and considering relevant factors, consumers can make informed decisions when switching water suppliers. Although certain considerations and challenges exist, opening the water market signifies a significant step towards a more competitive and customer-focused water industry in the UK. Embracing the power of choice enables consumers to contribute to a thriving water sector that prioritizes their needs and delivers sustainable, high-quality water services.
