Did you know you can choose your business water supplier?
In England and Scotland, businesses can pick their water retailer. We review your bill, meter and charges, and move you to a better-suited retailer where it makes sense. Same water, same pipes.
Can a business switch water supplier?
In England and Scotland, businesses can choose their water retailer. The retailer handles your billing and customer service, while your local water company still supplies the water and looks after the pipes. DNS Utilities reviews your tariff, meter and bills and helps you move retailer where that makes sense.

What we do for your business water
Retailer comparison
We compare retailers on service and tariffs for your premises.
Bill and meter review
We check whether you are billed on real meter readings rather than estimates.
Surface water drainage
Some businesses pay for rainwater draining to the public sewer even when it does not. We help you check.
Spotting leaks
A sudden jump in usage can point to a leak. We flag unusual changes.
Empty premises
Make sure you are not paying for sites that are closed or vacant.
Food and trade effluent
Food businesses and similar sites may pay trade effluent charges. We help you understand them.
Retailer or wholesaler: who does what?
| Your retailer | Your wholesaler (local water company) | |
|---|---|---|
| Sends your bill | Yes | No |
| Meter reads and customer service | Yes | Only for the network |
| Supplies the water and owns the pipes | No | Yes |

Water management: your questions answered
Business water competition applies in England and Scotland, where you can choose your retailer. If you are elsewhere, we can still review your bills and charges.
No. The same water company supplies your water through the same pipes. Only your billing and service provider changes.
Common reasons include estimated readings, leaks, surface water drainage charges, and bills for empty premises. A review can pinpoint the cause.
A charge for rainwater from your site draining to the public sewer. If your site does not drain there, you may be able to have it reduced.
A recent bill showing your supply point ID (SPID) and charges. That is enough to start.
A review is free and carries no obligation. We will explain how we are paid before you sign anything.
