When a site takes supply without a negotiated contract, for example after moving in or letting an agreement lapse, the retailer bills on its published deemed or out-of-contract terms, which differ by wholesale region and are updated each charging year. We never republish the figures: they change annually, so the only reliable source is the current document.
Everflow publishes its deemed and out-of-contract terms in its own charges documents, linked below. Check the document for your wholesaler region and charging year before comparing it against a negotiated offer.
Everflow is an independent business utilities retailer founded in 2015 by Josh Gill. The licensed retail entity, Everflow Limited (company number 09651912), was incorporated at Companies House on 23 June 2015 and holds a water supply and sewerage licence (WSSL) from Ofwat. The business started on Teesside ahead of the English non-household water market opening in 2017 and is now headquartered at Traynor Way, Hub 2, Peterlee, County Durham, with a second office in Nuneaton and more than 200 employees. For 2024 it reported revenue of over £186 million, up 21%, with EBITDA of £5 million, and grew its customer base from 94,431 to 110,411, describing itself as the UK's fifth-largest water retailer.
Ownership sits mainly with the management team following a buyout completed in October 2023, at which point private equity firm Perwyn, an investor since June 2018, partially exited with a return of around 2.5 times while retaining a significant minority stake. Craig Dallison, previously chief growth officer, became chief executive in November 2023, with founder Josh Gill remaining a shareholder and board member. The group is notably technology-led: it launched Everflow Tech in 2019, whose Eclipse retail management and billing platform underpins its own quoting and billing and has been sold to rival water retailers.
Everflow supplies business water and wastewater services in the open markets of England and Scotland; its published Charging Statement covers deemed customers in England and default customers in Scotland, with deemed charges in England capped under Ofwat's Retail Exit Code. In 2024 it expanded into business waste collection and broadband and phone services, and its environmental arm offers water efficiency audits, smart water loggers, leak identification and an EcoMOT usage reduction programme. Its regulatory record includes being named by CCW among the three poorest performers for business customer complaints in 2018/19 and receiving, in January 2023, an Ofwat Direction (alongside four other retailers) to comply with Retail Exit Code price limits for out-of-contract customers.
Frequently asked
Everflow is independent and majority-owned by its management team. A management buyout completed in October 2023 saw the team take a majority stake, while private equity firm Perwyn, an investor since June 2018, partially exited with a return of around 2.5 times and kept a significant minority holding. Founder Josh Gill stepped back from day-to-day leadership at the same time but remains a shareholder and board member. No water wholesaler or overseas utility owns Everflow.
Everflow publishes its deemed and default charging arrangements in a Charging Statement on its website, which we link to from this page, alongside separate Water Deemed Terms and Conditions. If you occupy premises Everflow supplies without agreeing a contract, you become a deemed customer in England or a default customer in Scotland and pay the rates in its Deemed Contract Rates Schedule. These are usually higher than negotiated contract rates, and in England they cannot exceed limits set by Ofwat's Retail Exit Code, so check the current document before comparing quotes.
Everflow supplies business premises across England and Scotland, the two open non-household water markets in Great Britain. Everflow Limited holds a water supply and sewerage licence (WSSL) issued by Ofwat for England, and its published Charging Statement also covers default customers in Scotland across multiple wholesaler regions. Wales and Northern Ireland are not listed as supply areas on its site. A business with premises in both England and Scotland can place all of its sites with Everflow as a single retailer.
Everflow lists separate sales lines on its website: 0330 818 7216 for water, 0330 822 1716 for waste and 0330 822 1742 for connectivity, with 0330 6600 137 shown on its help centre. Sales lines open Monday to Friday 09:00 to 17:00, and customer service is available Monday to Friday 08:00 to 18:00 plus Saturday 09:00 to 12:00. Its head office is Traynor Way, Hub 2, Peterlee, SR8 2RU, and the site also offers online forms and a customer portal.
Everflow is built primarily for small and medium-sized businesses rather than large industrial portfolios. It supplies more than 100,000 premises, pitches its pricing at small business customers, and provides a customer portal for bills and meter readings. Because it is licensed in both England and Scotland, a business with sites in both nations can consolidate them with one retailer, and since 2024 it can add waste collection and connectivity to the same account. Large, complex estates should compare its offer against industrial and commercial specialists.
Your water would keep flowing and your sites would be moved to another retailer. Physical supply is delivered by regional wholesalers, not the retailer, so taps and drains are unaffected. If a retailer leaves the market through insolvency or licence revocation, Ofwat instructs the market operator MOSL to run the interim supply allocation process, which transfers supply points to retailers that have opted in to receive them. Customers do not need to take any action, and billing then continues with the newly allocated retailer.
Craig Dallison is Everflow's chief executive, appointed in November 2023 after serving as chief growth officer. He took over from founder Josh Gill, who stepped back from operational leadership following the management buyout but remains a shareholder and board member. The wider leadership team listed on Everflow's website includes chief financial officer James Cleave, chief operating officer Jim Garrett, chief technology officer Andy Sheldon, chief commercial officer Paul Lucherini and chair Lucy Armstrong, all of whom also appear as directors at Companies House.
Everflow's record is mixed historically but stronger on its own recent measures. CCW, the water consumer watchdog, named it among the three poorest performers for business customer complaints in 2018/19 and criticised slow responses. In January 2023, Ofwat directed Everflow and four other retailers to comply with Retail Exit Code maximum price limits for out-of-contract customers. The company cites on its website a 4.7 Trustpilot rating, a retention rate of around 98% and 16% customer growth during 2024.
