Open-market water for non-household sites — every Ofwat-licensed retailer, one decision.
Since April 2017 the English non-household water market has been fully contestable. If you run a business, charity, school, surgery or public-sector building, you can — and should — choose your retailer. We compare every Ofwat-licensed retailer in one tender and consolidate multi-region portfolios under a single billing relationship.
The non-household water market is split between wholesalers (who own the pipes — Severn Trent, Thames, United Utilities, Yorkshire Water and others) and retailers (who issue your bills and run customer service — Castle Water, Wave, Business Stream, Water Plus, Everflow and 10+ others). The wholesaler is fixed by your geography; the retailer is your choice. Most businesses are still on the default retailer their old water company moved them onto in 2017 — and are paying more than they need to.
Compare every Ofwat-licensed retailer in one tender
We hold trading agreements with all major business water retailers, including Castle Water (the UK's largest non-household retailer), Wave Utilities, Business Stream, Water Plus, Everflow, SES Business Water and the new entrants. We tender once and present a single comparison sheet — wholesale charges (fixed) plus retailer margin, customer service SLA and billing format.
- Single-site SMEs and micro-business tariffs
- Multi-region portfolio consolidation under one retailer
- Sustainability scorecard (where ESG drives the choice)
- Bespoke billing format for accounts payable systems
Leak allowance recovery — up to 6 years backdated
If your business has had an underground leak that was identified and repaired, you may be entitled to a leak allowance refund from your retailer covering the unaccounted-for water. Many businesses miss this entirely. We review six years of consumption data, identify anomalies, and submit allowance claims — typically recovering between £2,000 and £30,000 per affected site.
Trade effluent and surface-water reviews
Trade effluent charges and surface-water drainage rebates are two of the least understood areas in business water billing. Sites with permeable car parks, soakaways or no surface drainage connection are often paying for drainage they cannot use. We desktop-survey your sites, identify rebate eligibility and submit applications.
Multi-utility billing under one retainer
For multi-site portfolios — retail chains, care groups, hotel groups, public sector — we coordinate energy and water under a single procurement calendar and invoice management workflow. One file, one team, one renewal diary.
Frequently asked
- No. The wholesaler (the company that owns the pipes) does not change — only the retailer who bills you. The water flowing into your taps is identical.
