Pros & cons
What we hear from E.ON customers
Strengths
- Big Six scale: the parent group serves around 3.8 million UK homes, with mature operational processes, a 24/7 emergency line and a Coventry-based UK head office.
- The E.ON Next app (Kraken platform) is highly rated on both app stores - 4.6 on the Apple App Store and 4.3 on Google Play - with half-hourly smart-meter data, in-app direct-debit changes and live chat.
- Strong support for vulnerable customers - Priority Services Register, Warm Home Discount automatic-payment scheme, Energy Fund grants and a dedicated bereavement team.
- Free SMETS2 smart-meter installation, including for legacy customers, plus a remote DCC re-enrolment programme for SMETS1 meters that went "dumb" after a previous supplier switch.
- No exit fee on the legacy Standard Variable Tariff - you can leave at any time, and the migration to E.ON Next is also free, with the same account number, balance and direct debit carried over.
Weaknesses
- No fixed-price deals on the legacy E.ON licence any more - the only domestic tariff still live is the Standard Variable Tariff, capped quarterly by the Ofgem Energy Price Cap.
- Phone lines on the legacy brand are Monday-Friday 9-5 only (no weekend or bank-holiday cover for non-emergency queries) - escalations often need a follow-up call.
- Citizens Advice complaint-handling rank has hovered in the middle of the supplier-performance table for the last several quarters - not the worst, but not best-in-class either.
- Historical mis-selling fines (£12m to 330,000 customers in 2014, the largest Ofgem penalty against a UK supplier at the time) still surface in older review threads and Reddit posts.
- Migration to E.ON Next is mechanical and free, but communication is uneven - some customers report unclear timelines or two billing systems running in parallel for a few weeks.
Selectra verdict
Our independent take on E.ON
E.ON is the safest default choice for legacy customers who prioritise operational stability and the breadth of a Big Six brand over the cheapest possible unit rate. The combination of a mature app (via E.ON Next), free smart-meter installation, accessible phone support and an integrated Energy Fund for vulnerable households means you rarely need to switch supplier just to fix an underlying problem.
For pure-price hunters, smaller suppliers and the equivalent E.ON Next fixed deal will typically beat the legacy SVT by £60-£120 a year for a typical household. The single most valuable thing a legacy E.ON customer can do in 2026 is: (1) accept the free migration to E.ON Next, (2) compare the post-migration fixed deal against Octopus, EDF Simply Fixed and Good Energy on real annual kWh, and (3) only stay on the SVT if you genuinely need the continuity of paper bills and phone-first service.

Selectra editorial takeaway
Reading the reviews together
Reading the six reviews together, E.ON presents a familiar Big Six pattern: strong on app, smart-meter installation and vulnerable-customer support, weaker on phone-channel response times and on the cross-platform handover between the legacy brand and E.ON Next. Five-star reviews cluster around engineers, the Energy Fund and the Kraken-based app; lower-star reviews concentrate on legacy phone waits, estimated-bill issues on smart meters with weak DCC coverage, and migration friction.
The practical playbook for an E.ON customer in 2026 is: use the app, not the phone line; accept the free migration to E.ON Next; book the SMETS2 install online; and apply to the Energy Fund the moment you fall behind, not after the arrears have stacked up.
Selectra explains
E.ON's online presence: expert analysis
Author: Selectra UK energy team · Updated May 2026
E.ON has one of the largest UK supplier review footprints (Big Six scale, ~3.8 million customers, 25-year UK retail history). Public signals are broadly consistent across channels: strong app and engineer scores, mid-table regulator data, weaker legacy phone-channel feedback. The migration to E.ON Next has shifted positive reviews onto the new brand while leaving more recent negative reviews on the legacy book.
Channel
Trustpilot
4.0/5
~78,000 reviews
Trustpilot skews positive thanks to a high volume of recent post-migration reviews on E.ON Next. The most-mentioned positives are smart-meter installs, the app and helpful agents on the new brand. Negatives concentrate on legacy billing handovers.
Channel
Google reviews
3.6/5
~9,500 reviews
Google scores sit a clear step below Trustpilot because Google captures more unprompted complaint reviews and fewer review-invite responses. Common themes: smart-meter signal issues and slow phone response on the legacy line.
Channel
Citizens Advice supplier performance
3.3/5
Quarterly regulator-supplied data
Mid-table on the Citizens Advice supplier-performance ranking (around 10th of the major UK suppliers). Best on switching, weakest on complaint handling within eight weeks - a familiar Big Six pattern.
Channel
Apple App Store (E.ON Next app)
4.6/5
~32,000 ratings
One of the best-rated Big Six apps on iOS. Most-praised: photo-based meter capture, live chat and in-app DD changes. Most-complained: occasional sign-in loops after iOS updates.
Channel
Google Play (E.ON Next app)
4.3/5
~25,000 ratings
Strong Android scores too. Slightly lower than iOS, mostly due to a handful of Android-specific notification bugs. Recent updates have closed most outstanding issues.
Channel
Reddit r/UKPersonalFinance and r/UnitedKingdom
Reddit threads are evenly split: positive on the Energy Fund, the app and engineer professionalism, negative on the historical 2014 mis-selling fine which still surfaces in older comparison threads. Active community moderators flag misleading "switch to X" posts.
Channel
Ofgem regulatory record
No major active enforcement cases in 2026. Historic record includes the 2014 £12m mis-selling penalty (the largest of its kind at the time). Compliance with the Standards of Conduct and the Energy Price Cap is currently in line with the wider Big Six.
Channel
Press coverage (BBC, Guardian, This is Money)
Press coverage concentrates on the migration to E.ON Next, smart-meter rollout milestones and quarterly cap-related price changes. Reporting is factual and E.ON tends to engage on the record.
Selectra expert verdict
Reading every channel together
Triangulating across Trustpilot, Google, the Citizens Advice supplier-performance table, both app stores, Reddit and the Ofgem record, E.ON's online presence is solidly defensible for a Big Six legacy supplier. App scores are top-quartile, regulator data is mid-table, and the historical 2014 mis-selling penalty still casts a long tail on older comparison content but has materially improved recent compliance.
If you read only one signal, read the Citizens Advice supplier performance table - it is the only score built from regulator-supplied complaint and switching data rather than self-reported reviews, and it tracks the operational handover between the legacy brand and E.ON Next in something close to real time.
Reviews don't pay the bill — the tariff does.
A great supplier still costs you money if you're on a bad tariff. Compare E.ON against every other UK supplier on the price for your actual usage.
Common questions
E.ON reviews — frequently asked questions
E.ON is regulated by Ofgem and bound by the Standards of Conduct that protect domestic customers. Reliability is best judged against your own usage profile: read recent reviews, check the Citizens Advice star rating for E.ON, and confirm the supplier's customer-service hours match when you actually need to call.
Trustpilot, Google Maps and app-store reviews reflect real experiences but are often skewed toward dissatisfied customers (people only post when something goes wrong). The most balanced single rating is Citizens Advice's quarterly supplier performance table, which scores all UK domestic suppliers on complaint handling, transfers, debt and communication — and is built from regulator-supplied data, not self-reported.
Confirm the unit rate (p/kWh) for both gas and electricity, the daily standing charge, the contract length, any exit fee (typical range: £25-£75 per fuel), and whether the deal requires a smart meter. Always cross-check the headline price against several other suppliers based on your actual postcode and annual kWh consumption from a recent bill.
If you're a current or former E.ON customer, share your experience on Trustpilot UK (search the supplier name), Google Maps (write a review on the E.ON business profile), or the Apple App Store and Google Play if you've used the mobile app. Selectra also collects independent reviews to help future customers compare suppliers objectively.
