Castle Water - Business Water Supplier Review 

When the water market was regulated, commercial water consumers could not choose their water suppliers. They simply had to accept the rates, services, and support offered by their regional water supplier.

The water market was deregulated in April of 2017. From April 2017 onwards, business owners could choose their water supplier. Water suppliers can no longer rely on their reputations. Instead, they have to create competitive business water services that suit a range of needs. 

Castle Water is one of the most trusted water suppliers on the market. It has thousands of positive reviews from existing customers. But in the newly deregulated market, the most reputable supplier might not be the best option. Our experts have scrutinised Castle Water’s services, ratings, and transparency for business owners who want to make the switch. 

Introduction to Castle Water

Castle Water was founded in 2014. This relatively new independent retailer claims to be the leading commercial water supplier in the UK. It was made with a clear vision: to create ‘an independent water retailer providing excellent water service at the best possible price.’ More than 350,000 business water consumers in the UK rely on Castle Water.

It is proud to offer business owners across the UK tailored water services. SMEs, start-ups, and sole traders can access personalised plans and tariffs from Castle Water. Even better, this supplier promises business owners up to 80% savings on their fixed water charges. 

Prospective Castle Water business water customers will be pleased to learn that it invests in sustainability programmes. It is constantly looking for ways to ‘reduce or prevent pollution or waste’ and to ‘minimise our consumption of resources.’ 

In 2021, Castle Water won Ofwat’s Water Breakthrough Challenge for Innovation. In conjunction with other interested parties, Castle Water led a ‘Drought Resilience Through Innovation’ pilot scheme to provide ‘more flexible local water supplies, improve drought resilience, and incentivise business customers to save water.’ 

This commercial water supplier has invested in lots of different branches of sustainability. In 2021, it began efforts to carbon balance its printing operations, which aims to reduce its overall carbon emissions footprint. To get employees involved, Castle Water has also installed Electric Vehicle charging points at its head office in Blairgowrie, Scotland. 

Castle Water Commercial Water Services

Castle Water delivers water services that are ‘tailor-made for your business - whatever its size.’ It offers a comprehensive range of services including fresh water, wastewater, and trade effluent release. Customers can even access consolidated billing for all of the above services and drainage services. 

Trade effluent is an often misunderstood aspect of water services. It is defined as liquids that are produced on non-domestic premises for non-domestic purposes. For example, water that cleans cars at a car wash is classed as trade effluent. 

Although most Castle Water business water customers operate SMEs and start-up businesses, multi-site, industrial, or large businesses can also depend on Castle Water. As part of its offering for larger customers, Castle Water has created a dedicated team of regional Commercial Relationship Managers. Business owners who have premises that use more than 6,000m³ of water each year are eligible for this service. It aims to give customers ‘assistance for even the most complex queries.’ 

Commercial water consumers can also access additional water management services including Automatic Meter Reading (AMR), water efficiency audits, contingency planning, and leak detection and repair.

Castle Water Business Water Reviews

Gone are the days of blinding choosing a commercial water supplier. In the digital age, business services are more transparent than ever. Water suppliers can make bold claims, but sites such as Trustpilot reveal the truth. Trustpilot is a customer review site. Existing customers can leave real-time, realistic views about the services that they receive. 

Despite being a relative newcomer to the water market, Castle Water has a lot more reviews than some of the older suppliers that we have surveyed. Over 14,500 customers have written a review. 

Castle Water has 4.6/5 stars on Trustpilot and an overall average of excellent. 80% of customers think that the services are excellent, whereas only 8% of customers think that the services are bad. Excellent reviewers mention customer service representatives by name and applaud their quick response times. Negative reviewers claim that getting an answer from a representative is ‘near on impossible.’ 

Prospective Castle Water business water customers will be happy to learn that a representative promptly replies to all reviews. The representatives take accountability for problems and suggest steps that can lead to resolutions. This is one of the biggest signs that suppliers care about customer service.

Castle Water Average Business Water Prices

It is no secret that business owners are always looking for the lowest charges possible. Luckily for business owners, suppliers are very transparent about their charges. Like most of the water suppliers in the UK, Castle Water has an entire page dedicated to water charges. Business owners can scroll down and choose from a range of links. 

Commercial water customers who have metered premises will receive measured charges. Premises that do not have meters will receive unmeasured charges, which are calculated using the Rateable Value (RV) of the property. 

Curious Castle Water business water customers can also browse through the Scheme of Charges for wholesalers. This is just one of the ways that business owners can survey the market and make sure that they are getting a good deal.

Why Switch Commercial Water Suppliers?

Now that the water market is deregulated, water suppliers have to compete for new customers. Lots of suppliers have implemented a multi-pronged approach to target hot button topics such as sustainability, community, and customer service.

Here are some of the reasons why business owners switch suppliers. 

  • Lower unit rates - This is the most popular reason why business owners switch suppliers. Unit rates can be confusing at the best of times, but one thing is certain: the lower the rate, the lower the bills. Even small tweaks can make a big difference to monthly bills, especially for medium and large businesses. 
  • Better customer service ratings - Castle Water business water customers know how important customer services are. Customer services might not seem that important at first glance. When disaster strikes, customer service representatives can make or break day-to-day operations. Knowledgeable, friendly representatives can make all the difference when leaks occur or bills are incorrect.
  • Transparency - In the deregulated market, transparency is key. Business owners have a wide range of options and they want to find relevant information in a few clicks. Unfortunately, lots of water suppliers make vital information difficult to find.
  • Environmental involvement - Commercial water suppliers rely on natural environments. They have to invest in environmental programmes to ensure the longevity of their businesses. By switching to a supplier that cares about sustainability, business owners can spend money on causes that are close to their hearts. 
  • Charitable contributions - There are hundreds of water-centric charities that water suppliers can invest in. WaterAid is one of the most popular charities amongst suppliers. It focuses on improving water hygiene in developing countries. Suppliers can even focus on charities that protect wildlife and support farmers in their regions. 

So, can you change business water suppliers? Non-domestic water consumers can only switch suppliers if they meet certain requirements. Read through our guide to discover whether your business is eligible to switch.
