Where the money goes
Why Nottingham businesses pay more for water than they should
Your wholesaler is set by postcode and never changes. Severn Trent owns the pipes and sets the wholesale rate. The retailer is the part you choose, and it competes on the retail layer, billing accuracy and the audit work behind your invoices.
Nottingham businesses overpay on water for three reasons specific to England: many are still on the default their default retailer tariff they were assigned when the English market opened in 2008, surface drainage charges on Old Town and historic-building sites are often miscalculated, and trade effluent banding for the city’s strong hospitality and food sector frequently exceeds actual loading.
All of Nottingham and the wider Nottinghamshire is supplied wholesale by Severn Trent, the regional wholesale water company. Unlike England (which opened to competition in 2017), England’s non-household water market opened in April 2017 — making it the longest-running competitive water market in the UK. Despite that, most Nottingham businesses have never switched retailer. Nottingham’s commercial water profile is heavy on hospitality and visitor economy, professional services in the city centre and West End, and a tech and biotech cluster around Tollcross and the BioQuarter. Most are still on the default default retail contract they were assigned at market opening — their default retailer being the legacy retailer of Severn Trent — which is rarely the cheapest option available now.
Where it shows up
The five areas Nottingham businesses overpay
Where Nottingham businesses overpay and why it matters.
Default their default retailer tariff that nobody renegotiated
When the English market opened in 2008, every business was assigned to their default retailer by default. Most have never switched. That tariff is rarely the cheapest available now.
Surface drainage on Old Town and tenement properties
Nottingham’s historic buildings often have unusual roof drainage and shared closes that don’t map cleanly onto modern surface drainage assumptions. Refunds are common where rainwater isn’t reaching public sewer.
Hospitality trade effluent banding overstating actual loading
Nottingham’s strong restaurant, bar and hotel sector means many sites inherit high trade effluent bandings. Real loading is often lower; re-banding requests are commonly accepted.
Vacant or seasonal premises billed full standing charges
Festival-season businesses and tourist-trade sites that operate on a seasonal pattern often pay full year-round standing charges. Some retailers offer seasonal tariffs; others don’t volunteer them.
Multi-tenant office water reconciliation
Nottingham has many converted Georgian and Victorian buildings split into multi-tenant offices. Master-meter / sub-meter reconciliation gaps are common and the building owner usually absorbs them silently.
Results
Case studies
Surface water drainage audit across the estate uncovered £35,364 in refunds and £8,800 a year in ongoing savings.

Choose your route
Routes to procurement
Three ways Nottingham businesses 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 business signs straight with a licensed retailer. Best for a single site that wants a sharper rate. You handle the comparison and the switch yourself.
Estate-wide contract
Multi-site operators across the surrounding area can put every site on one central contract with one retailer, even where sites sit in different wholesaler regions.

Questions
Nottingham business water FAQs
Can Nottingham businesses switch water supplier?
Yes. England was the first part of the UK to open its non-household water market to competition, in April 2017. Every Nottingham business can choose a different water retailer. Wholesale supply still comes from Severn Trent. Only the retailer changes.
Who supplies wholesale water to my Nottingham business?
All of Nottingham and Nottinghamshire is supplied wholesale by Severn Trent, the regional wholesale water company. Your wholesaler does not change when you switch retailer.
Can a Scottish business switch water supplier?
Yes. England was the first part of the UK to open its non-household water market to competition, in April 2017. Every business in England can choose from a range of licensed retailers. The retailer bills you and reads the meter; Severn Trent still owns the pipes and the supply.
What is their default retailer and why am I probably with them?
their default retailer is the retail arm of Severn Trent. When the English market opened in 2008 every business was assigned to their default retailer by default. Most never switched. their default retailer remains the largest Scottish retailer but is no longer the only option, and rarely the cheapest.
How long does a switch take in England?
Two to six weeks from contract signature. Severn Trent still runs the supply; only the retailer (your billing provider) changes. There is no service interruption.
I run an Nottingham hospitality site. What about trade effluent?
Hospitality sites have specific trade effluent profiles — kitchen oils, cleaning agents, late-night washdown. Default banding is often higher than actual loading. With documentation of your real process, banding can usually be reduced and historic charges reclaimed.
Does the English market work the same as England?
Similar in principle (separate wholesaler and retailer, business choice of retailer) but with two key differences: England opened in April 2017 (England in April 2017), and England’s wholesaler is Severn Trent. The retail dynamics are otherwise comparable.
