Compare business water suppliers now!
In Coventry the water is Severn Trent’s to deliver, and the 2017 opening of the market did not change that. What it changed was the billing relationship sitting on top of the supply: the retailer that invoices you, reads the meter and runs the account. That part is yours to choose, while the supply itself carries on unchanged.
We are an independent broker working for businesses across the city, from the manufacturing and logistics estates at Ansty and Prologis Park to the two universities and the city-centre offices. We compare retailers against your real meter, manage the switch from start to finish, and read recent bills for the things that quietly inflate a Coventry account, usually drainage and trade effluent.
- Severn Trent remains your wholesaler whoever you switch to, so it is the same supply through the same mains.
- Your retailer is the part you can change: billing, meter reads, account team and contract.
- Switching is paperwork, not pipework, and there is no break in supply while it happens.
- Coventry’s big manufacturing sheds, business parks and student blocks are where charges most often drift.
Why Coventry businesses overpay on water
Coventry grew up around the car industry, and the footprint it left is the clue to where the overcharging hides. The city is ringed with large manufacturing units, distribution sheds and business parks, the sort of premises with sprawling roofs and yards. A site like that rarely drains the way the billing assumes: a lot of that rainwater runs to a soakaway or a watercourse rather than the public sewer, yet the surface water drainage charge often keeps being applied as though all of it goes back to Severn Trent’s network.
The other common one in Coventry is trade effluent. Plenty of the city’s manufacturing and food sites discharge process water, and once a trade effluent band is set it rarely gets revisited, even when the real loading is lower. With proper figures the band can usually be reduced and the difference reclaimed.
A quick read of your last few bills usually tells us which of these is out of line. Where it is, a water audit puts it right and recovers what was overpaid, up to six years back.
Can a Coventry business switch water supplier?
Yes, and every non-household site in England has had that right since April 2017, from a car-plant supplier on the edge of the city to a coffee shop in the centre. Severn Trent keeps running the supply through the same network; only the retailer that bills you changes. We line up quotes from the retailers we work with against your postcode and usage so the comparison is real.

How switching works in Coventry
It’s admin from start to finish, and your supply never stops.
Coventry sectors we help most
Some kinds of Coventry business turn up more than others, usually because their water profile is unusual enough that the default billing gets it wrong.
Areas of Coventry we cover
If you run a business anywhere in the Coventry area, you can switch, and we’re not tied to the city centre.
Across the city: the city centre and Friargate, Foleshill, Canley, Tile Hill, Binley, Longford, Whitley and the business and industrial parks at Ansty Park, Prologis Park, Bayton Road and Coventry Business Park.
Sectors we most often support: manufacturing, food production, hospitality, retail, education, healthcare and commercial property. Multi-site operators can pull everything onto one consolidated contract, and larger estates can run a full corporate tender.
Most of our Coventry work comes from the larger water users: the manufacturing and distribution estates at Ansty Park, Prologis and Bayton Road, the university campuses and their accommodation, and the city-centre hospitality around Friargate and the Cathedral Quarter. If your meter has not had a proper look in a year or two, it is usually worth checking.
Coventry business water FAQs
Who supplies water to my Coventry business?
Severn Trent is the wholesaler for Coventry and the wider region, it owns the mains and treatment works and delivers the supply. Since 2017 a separate retailer handles your billing, meter reads and contract, and that’s the part you can change. Your wholesaler stays the same whoever you switch to.
When could Coventry businesses start switching?
Coventry businesses, like every non-household site in England, have been able to switch since 1 April 2017, when the market opened to competition. Scotland opened earlier, in 2008. Most Coventry firms have never moved retailer, even though the right has been there for years.
Will my water supply be affected if I switch?
No. It is an administrative change only. The same Severn Trent mains carry the same water to your Coventry premises at the same pressure, with no engineer visit and nothing switched off. The only change is the company that sends the bill.
Is Coventry different from Birmingham for business water?
Both sit in the Severn Trent region and both can switch retailer, so the mechanics are the same. The difference is the mix of premises: Coventry leans heavily on manufacturing sheds, logistics parks and university sites, where in Birmingham there is a far larger city-centre office and hospitality base. If you run sites in both, we can handle them together.
Can I claim money back on past bills?
Yes, where a charge was demonstrably wrong. The backdated window is six years. The usual Coventry grounds are surface water drainage that doesn’t reach the public sewer, an overstated return-to-sewer figure, or a trade effluent band set higher than your real loading.
Do manufacturing and logistics sites in Coventry overpay on water?
They often do. The big sheds around Ansty, Prologis Park and the M6 have large roofs and yards, and a lot of that rainwater never reaches the public sewer, yet the surface water drainage charge is applied as though it does. Manufacturing sites also carry trade effluent bands that are rarely revisited. Both are recoverable up to six years back where the charge is wrong.
We run sites in Coventry and Birmingham. Can you handle both?
Yes. Both sit in the Severn Trent region, so one retailer can usually bill the lot on a single contract. We look after multi-site businesses across the Midlands and consolidate the invoicing where it helps.
