Most businesses in England and Scotland can switch their water retailer thanks to the open water market, potentially cutting costs and consolidating billing. Eligibility depends on your location and meter type. As with energy, comparing retailers and switching is straightforward — and many businesses have never reviewed their water supply at all.
For years, businesses simply paid whichever water company served their area, with no choice involved. That changed when the water market opened to competition, allowing eligible businesses to choose their water retailer rather than being tied to a regional monopoly. Yet awareness remains low: a large share of businesses have never switched or even reviewed their water supply, often because they assume — as with the old days — that they have no choice.
That inertia is exactly why water is one of the most overlooked savings opportunities for a business. While many owners scrutinise energy costs, water bills tend to be paid on autopilot.
Eligibility comes down mainly to where you are and how you're supplied. Businesses in England and Scotland can generally choose their water retailer under the open market. The position in Wales and Northern Ireland differs, so it's worth checking your specific circumstances. Beyond location, factors like your meter and the nature of your premises can affect your options. If you're unsure whether you qualify, we can check it for you.
Switching water supplier isn't only about a lower unit price — though savings are often available. The benefits tend to fall into three areas: cost, through more competitive retail charges; billing, by consolidating multiple sites or accounts onto a single, clearer bill; and service, with a retailer who's more responsive than a default regional supplier. For multi-site businesses in particular, simpler consolidated billing can be as valuable as the saving itself.
Water rarely sits alone — waste is the natural companion, and it's just as commonly overpaid because businesses stay with the same provider out of habit. Reviewing both at once means a single exercise can uncover savings across two utilities most owners never think to question. We work with specialist water and waste suppliers, so we can check both alongside your energy in one go.
The process mirrors an energy switch. Send us a recent water bill, we review your eligibility and compare available retailers, and if there's a better option we handle the switch for you. Your actual water supply is unaffected — the pipes, the network and the service to your premises stay exactly as they are; only the retailer you're billed by changes.

Can all businesses switch water supplier?
Most businesses in England and Scotland can, thanks to the open water market. The position differs in Wales and Northern Ireland, and your meter and premises can affect eligibility — so it's worth checking your specific situation.
How much can switching business water save?
Savings vary by usage, location and your current charges. Beyond price, many businesses also benefit from simpler consolidated billing and better service — particularly across multiple sites.
Does switching water supplier change my pipes or supply?
No. Switching changes only the retailer who bills you. The physical water supply, pipes and network serving your premises stay exactly the same, with no interruption.
