E.ON Next Business is the modern, digital-first business supplier that absorbed the old npower SME book in 2023. This 2026 review breaks down what they sell, what their pricing actually looks like, the smart-meter-only quirk that catches some businesses out, the renewable backing story (REGO + nuclear PPAs), customer service performance, pros, cons and the alternatives that beat them on price or scope.

E.ON Next vs E.ON UK: what changed in 2023-2026
The brand picture matters because customers get confused. The structure in 2026:
- E.ON SE — the German parent group, headquartered in Essen. One of Europe’s largest utilities.
- E.ON UK — the legacy UK retail and generation business. Now mainly handles industrial & commercial (I&C) accounts, large corporates, EV infrastructure (E.ON Drive), and renewables development.
- E.ON Next — the consumer and SME-facing digital brand, launched in 2021. In 2023 the npower SME book was migrated into E.ON Next, taking it from ~3 million to roughly 5.5 million accounts before some attrition. 2.5 million of those are active business accounts in 2026.
Operationally, E.ON Next runs on the Kraken platform (licensed from Octopus) for billing and customer ops — which is why their service has improved markedly since the npower transition. Industrial & commercial customers still sit on the legacy E.ON UK platform with traditional account managers.
For most SMEs reading this, the relevant brand is E.ON Next Business. For 1m+ kWh corporates, you’ll be talking to E.ON UK Industrial & Commercial.
E.ON Next Business product range 2026
E.ON Fixed Online
The standard SME product. 12 or 24 month fixed contract, smart meter required, set up and managed entirely online via the E.ON Next portal. Per-kWh rate locked, standing charge locked. This is what 70%+ of E.ON Next business customers are on.
E.ON Pulse
A smart time-of-use tariff aimed at SMEs that can shift load. Cheaper unit rate at off-peak periods (typically 9pm-7am and weekends), more expensive at evening peak (4-7pm). Net saving for shift-able loads is usually 0.8-2p/kWh on the all-in rate. Needs SMETS2 in HH-enabled mode.
E.ON Drive (EV charging)
For businesses installing EV chargers on-site (depot, car park, customer-facing) E.ON Drive bundles charger hardware, installation, OCPP back-office and the energy supply. Public-charging-network access too via E.ON Drive RFID. Prices for own-depot charging are typically 22-26p/kWh on the EV-dedicated meter; public-network rates vary.
For fleets running 5+ vehicles this is one of the most credible UK propositions outside Octopus Electroverse and BP Pulse for Business. EV charger CAPEX can also be financed inside the energy contract over 3-7 years.
E.ON Variable Business
The deemed/out-of-contract product. Avoid. Rates are typically 6-12p/kWh higher than a fresh fixed quote — standard punishment for not renewing on time. See our deemed contracts guide.
E.ON UK I&C contracts
For 500,000+ kWh users, traditional fully-bespoke contracts including flexi-purchase, baseload + peak shapes, REGO + nuclear PPA matched product, and 24×7 carbon-free options under E.ON UK’s parent group’s renewable PPA portfolio.
E.ON Next Business pricing 2026
Indicative ranges from current quote samples:
- Electricity unit rate: 23-26p/kWh for SMEs under 50,000 kWh, 17-22p/kWh for 50,000-250,000 kWh sites, 14-18p/kWh on HH meters.
- Standing charge (electricity): 38-52p/day for SMEs.
- Gas unit rate: 5.5-8p/kWh for SMEs on E.ON Next gas.
- Standing charge (gas): 28-42p/day.
E.ON Next is most competitive in the under-50,000 kWh band — SMEs with smart meters get sharp quotes here. Above that, EDF and SEFE typically beat them. Their gas pricing is solid but Crown Gas & Power and SEFE often undercut.

The smart-meter requirement: who it rules out
E.ON Next Business is unique among the Big Six in requiring a smart meter for new business contracts (with limited exceptions). If you have a SMETS1 or SMETS2 meter you’re fine. If you have a traditional electromechanical or AMR-only meter, E.ON Next will install a smart meter as part of contract setup at no charge — but the install slot can be 4-12 weeks out, which means your switching window might slip.
For half-hourly CT-metered sites (the >100 kW capacity bracket), the rule is different: you can keep your existing HH meter, and E.ON Next reads the data flow from your DC/MOP via the standard P272 industry process. See our HH meters guide for the basics.
Why does E.ON Next insist on smart meters? Three reasons: (1) accurate billing eliminates 80% of complaint volume, (2) it enables time-of-use products like Pulse, (3) it reduces operational cost so they can pass through tighter margins.
Renewable backing: REGO + nuclear PPA
All E.ON Next Business electricity is REGO-backed renewable as standard — the certificates come from a mix of UK wind (parent group’s offshore portfolio plus market purchases) and a smaller share of solar and hydro. The fuel mix is published annually.
Behind the renewable certificates, E.ON UK also has long-term nuclear PPAs with EDF’s UK fleet (Heysham, Hartlepool, Torness) and from 2027 onwards expects to take a slice of Hinkley Point C output. That’s why E.ON Next can offer near-baseload zero-carbon matching to corporate customers without owning the generation themselves — they buy it from EDF on multi-year contracts.
For an SME just wanting REGO-backed green electricity, this is more than enough. For an RE100 reporter wanting time-stamped 24×7 carbon-free, EDF Direct or Drax are usually a tighter fit. See our renewable business energy guide.
Customer service in 2026
The shift onto Kraken in 2023 was transformative for E.ON Next service. Current performance:
- Trustpilot: 4.6 / 5 (the second-highest of any major UK supplier after Octopus).
- Average phone wait: 3-5 minutes — not best-in-class but a major improvement on legacy npower.
- UK-based contact centres in Leicester, Bolton and Nottingham.
- WhatsApp and live chat support, both staffed by humans (not bots) for billing and contract issues.
- Dedicated account managers for 100,000+ kWh sites.
The most common 2026 complaint is around the smart meter install lead time, not billing accuracy.
Multi-site portfolio handling
E.ON Next supports multi-site businesses up to about 50 meters via the standard online portal. Above that, you typically migrate onto the E.ON UK I&C platform with a named account manager and consolidated invoicing. Aggregated portfolio quotes earn 0.3-1p/kWh discount over individual-site quotes — ask for the discount, don’t assume.
For 5+ sites, also read our multi-site meters guide.

How to switch to E.ON Next Business (or away from them)
Standard UK process: open your 6-month renewal window, sign a Letter of Authority (see our LoA guide), receive quotes, sign new contract. Smart meter install gets booked in parallel if needed. Switch completes 3-6 weeks after objection-window close. E.ON Next will not block valid outgoing switches but their loss-saves team will sometimes counter in the last 30 days.
