Business Water Management UK
Switch Supplier. Cut Bills. One Call.
Only 20% of UK businesses have ever switched water supplier. Since the market opened in 2017, you have been free to choose your retailer — and most businesses are still on a default tariff, paying more than they need to.
The market opportunity
Did you know you can switch your business water supplier?
The UK business water market was deregulated for England in 2017 (Scotland opened in 2008). The market works like energy wholesalers provide the infrastructure, licensed retailers compete to supply billing, metering and customer services. If you have not switched since 2017, you are almost certainly on a default tariff.

How it works
How the water market works — wholesalers vs retailers
Understanding the structure helps you see why switching retailers does not affect your water supply at all.
Wholesalers (stay the same)
– Maintain the pipe network
– Manage physical supply to your premises
– Treat wastewater and return it to environment
– Regulated by Ofwat — you cannot choose your wholesaler
Retailers (you choose)
– Handle billing and invoicing
– Read your meter and manage your account
– Provide customer service– Compete on price and service

Really good service, was a hard job to get us good a rates for electric. And Kilowatt did a fantastic job.
Rachel was very helpful, kind and understanding when I was having difficulty finding out who my supplier was. Also, with creating a good password. It is lovely, actually, to speak to another human rather than a robot. She put me at ease and we managed to sort out my new account.
Thank you very much
Priya has been absolutely outstanding throughout the entire process. Her professionalism, dedication, and attention to detail were exceptional from start to finish. She was always responsive, helpful, and went above and beyond to ensure everything was handled perfectly. I truly appreciate all of Priya’s hard work and would highly recommend her to anyone. She is a real asset to the team and deserves the highest recognition for her excellent performance.
Kilowatt Energy made what I assumed would be a complicated and time consuming process feel incredibly simple. Their AI powered bill audit system is genuinely impressive it quickly identified discrepancies and insights that would have been almost impossible to spot manually. Speaking to Tara felt like speaking to a friend and she explained everything in detail yet so easily.
I recently spoke with Shiv from Kilowatt Energy and had a really positive experience. He was incredibly helpful and even took the time to answer my calls outside of normal office hours, which made a big difference. I had some concerns about my energy bill, but Shiv explained everything clearly and helped me understand exactly what I was being charged for. It gave me a lot more confidence in managing my energy costs. It’s also reassuring to know he’s based in Derby, so I have someone local I can rely on to look after everything for me. Overall, a professional and reliable service that I’d definitely recommend.
Best gas, energy and electric supplier Derby in United Kingdom. Thank you Shubham...:)

I recently used Kilowatts UK to compare gas and electricity options for my business, and the experience was smooth from start to finish. The team was professional, responsive, and took the time to explain the different tariff options clearly without using pressure tactics. What stood out most was their communication and transparency throughout the process. They helped simplify what is usually a confusing and time-consuming task and made switching suppliers much easier than expected. I think one of the best gas and electricity supplier in Derby in United Kingdom (UK). I would recommend Kilowatts UK to any business looking to reduce energy costs and receive friendly, knowledgeable support when comparing gas and electricity providers.

FAQs
Does my water supply get interrupted when I switch retailer?
No. The wholesaler maintains the physical infrastructure, pipes, treatment, and delivery regardless of which retailer you use. Switching retailers only changes who bills you and manages your account. Your water supply is completely unaffected.
Is my business in Wales or Northern Ireland eligible to switch?
Wales currently allows switching only for very large users consuming over 50 megalitres per year. Northern Ireland has not yet opened the market to competition. If you are in England or Scotland, you are almost certainly eligible to switch.
How much could my business save by switching water supplier?
Savings vary by consumption and location. Smaller businesses typically save £150+ per year. High-consumption businesses that switched or renegotiated in 2024-25 saved an average of £2,200 annually. Some businesses have been overcharged by up to 65% on default tariffs before switching.
What is a SPID and where do I find it?
A SPID (Supply Point ID) is the unique identifier for your water supply point. You will find it on your current water bill. In England it is a 10-digit number followed by W (water) or S (sewerage). If you cannot locate it, give us your address and we will find it using the market operator database.
Can you manage water alongside our energy contracts?
Yes, this is one of our key advantages. We manage gas, electricity and water for our clients through a single named adviser. Businesses that consolidate utilities with one broker are 50-60% more likely to renew and significantly less likely to be targeted by cold-calling brokers managing multiple separate contracts.
