Business water rates
for small businesses

Small businesses and SMEs can make use of the excellent and high-quality services that Castle Water has to offer.

As well as providing bills that take numerous factors into account, such as geographic location, property type and pipe size, our excellent account managers will provide all the insight you need to keep your monthly consumption down.

This makes for reliably low business water rates for small businesses, and allows owners keep one of their core utility costs at a minimum.

How we calculate your business water bills

Your volumetric costs will be based on the following calculation:

Water Use (m3) x Cost of Water (£/m3)

Keep up with your meter readings, or set up Automatic Meter Reading to ensure that you are always submitting accurate water bills. 

We will calculate your fixed charges based on a multitude of factors, but will always work closely with you to ensure that you are paying the best possible rate for your situation. We have a fantastic track record on lowering fixed charges and in fact can deliver savings of up to 80% for our customers.

The combination of our high-quality fixed billing and reliable consumption – which we can help small business owners with – makes water bills an afterthought for owners.

Keep consumption low

Here are just a few of the ways that you can improve your business water consumption, which will help you keep volumetric bills at a minimum.

  • Regular Maintenance – Implement a proactive maintenance schedule to ensure that all plumbing fixtures, pipes, and equipment are in good working condition. Fix any leaks promptly, as even minor drips can waste a significant amount of water over time.
  • Employee Training – Educate your employees about the importance of water conservation and encourage them to report leaks or any water-related issues immediately. Implement water-saving practices in your workplace, such as turning off taps when not in use.
  • Regular Audits – Conduct regular water audits to monitor your business’s water usage patterns. Use the data collected to identify areas where water can be saved and implement efficiency measures accordingly.


Ultimately, being smarter with your water usage will help you take control of your bills, and when working with us you can rest assured that fixed costs are also kept to a minimum.
