Who we help
Business Water for Dental and Veterinary Practices
A practice does not use water the way a factory does, but the use it has is constant. Sterilisation cycles run all day, hands are washed between every patient, and kennels, theatres and surgeries are cleaned to clinical standards. On a small meter, the fixed charges often outweigh the water itself.
You can switch retailer. Practices in England have had that right since 2017, and Scottish practices since 2008. This page covers where practice water costs come from, how mixed-use buildings are treated, and where overpayment usually hides.
| Wholesale supply | Comes from regional water companies (Thames Water, Severn Trent, Yorkshire Water, and others). |
|---|---|
| Contracting | Single practices can contract directly with retailers, and groups can contract centrally across every site. |
| Biggest savings levers | Tariff reviews, fixed charge checks and surface water drainage banding. |
| Mixed-use buildings | A flat above the practice or a home-based surgery can split the supply between household and non-household billing. |
| Market opened | England in 2017 and Scotland in 2008. |
| Licensed retailers | Around 20 are licensed by Ofwat to supply non-household water. |
Where the money goes
Why practices pay more for water than they should
Small-meter premises carry proportionally heavy fixed charges. On many practice bills the standing charge, the drainage banding and the rateable value elements together outweigh the metered water, so checking those lines matters more than cutting use.
Practice bills tend to run on autopilot because water is a small line next to staff and equipment. Autoclaves, decontamination rooms and cleaning draw steadily through the day, and the tariff they sit on is rarely the one a comparison would choose.
Because usage is modest, the fixed elements dominate. A wrong meter size, an incorrect drainage band or a long run of estimated readings can move a small bill by a large percentage without anyone noticing.
Where it shows up
The five areas practices overpay
Where dental and veterinary practices overpay and why it matters.
Meter size and standing charges
Standing charges scale with meter size. Many practices sit on a larger meter than the premises needs, and the fixed charge follows the meter rather than the usage.
Surface water drainage
Drainage is often banded by rateable value or site area. A practice in a converted house or small unit can sit in the wrong band for years without anyone checking.
Deemed and default tariffs
A practice that has never switched sits on a deemed or default tariff. These are set to be safe for the retailer rather than sharp for the customer.
Mixed-use splits
Where a flat or living quarters share the supply, part of the use may belong on household terms. Getting the split registered correctly changes the bill.
Estimated readings
Small meters get read less often. A long run of estimates can drift well away from actual use, in either direction, until a real reading corrects it.

Case studies
Consolidated multi-site billing onto a single contract with one retailer and one point of contact.
Worth knowing
Eligibility and how the market works
Dental and veterinary practices count as non-household supply, so they are eligible to switch retailer through the open market run by Open Water. England opened in April 2017 and Scotland has been open since 2008.
Where the building includes living space, the household side stays with the regional household supplier and only the practice side enters the open market. Rateable values that sit behind some fixed charges are set by the Valuation Office Agency, so a banding query starts there rather than with the retailer.
The market
Switch water supplier for your practice
Yes. England’s non-household water market opened to competition in April 2017 and Scotland’s opened in 2008, so every practice can choose a different water retailer. Wholesale supply still comes from your regional water company; only the retailer (the company that bills you and reads your meter) changes.
The 12 retailers below are all licensed by Ofwat to supply non-household water. Pricing, service and sector experience vary from retailer to retailer.
Choose your route
Routes to procurement
Three ways practices typically bring a new water contract in. Each comes with its own trade-off between control, effort and how sharp the price lands.
Direct with a retailer
The practice signs straight with a licensed retailer. Best for a single practice that wants a sharper rate. You handle the comparison and the switch yourself.
Group-wide contract
Dental and veterinary groups can put every practice on one central contract with one retailer. Efficient at scale, and one renewal date covers every site.

Questions
Practice water FAQs
How do I get a quote?
Send a recent water bill for the practice. The SPID, annual volume and current retailer are all on it. We come back within two working days with an alternative quote and a flag if anything looks worth checking on meter size or drainage banding.
Do autoclaves and decontamination rooms affect the bill?
They draw more than people expect because they run all day, every day. The draw itself is normal metered use. What matters is the tariff it sits on and whether readings are actual rather than estimated.
We work from a converted house. Is that household or business supply?
If the premises trade as a practice it is non-household supply, even in a converted house. Where living space shares the supply, the split can be registered so each side is billed on the right basis.
Who fixes a burst pipe or supply problem?
The regional wholesaler still owns and maintains the network up to your boundary, whichever retailer you choose. Anything on the private side of the meter remains your responsibility.
Will switching disrupt anything on site?
No. A switch is paperwork rather than plumbing. There is no interruption to supply, no engineer visit and nothing changes for patients or clinical work.
We run several practices. Can they go on one contract?
Yes. Retailers operate nationally, so a group can consolidate sites in different wholesaler regions onto a single retailer, one contract and one point of contact.
Do we pay VAT on water?
Most professional services, including dental and veterinary practices, do not pay VAT on the water supply itself. VAT treatment follows your SIC classification rather than your choice of retailer.
