Octopus Energy review: 6 years as a customer

Affiliate disclosure: this post contains an Octopus Energy referral link. If you use it, both of us get £50 bill credit — the same £50 any Octopus referral earns, just attributed to me. It doesn't change the price you pay.

I switched to Octopus Energy in September 2019, from EDF, after a friend sent me a referral link. Six and a half years later I'm still a customer. I've moved house twice without any of the usual supplier drama, I've been through the 2022 energy crisis, I've switched tariffs four times, and I've had exactly one genuinely-bad customer service experience — 25 minutes on hold, once.

The question this review tries to answer is straightforward: is Octopus Energy any good? Not "is it cheapest right now" — that changes week to week. The real question is whether Octopus holds up over years, across house moves, through a pricing crisis, and under the kind of sustained real use that eventually turns a brand into either a recommendation or a grievance. Here's what I'd tell someone on the fence in 2026.

Three things I'd tell you up front

1. Octopus is consistently priced, not rock-bottom. In six years of comparison shopping, it has never been the absolute cheapest supplier at a given moment — but every time I've compared at a switch point, it has been in the top three. That's rare in UK energy.
2. Customer service you can actually reach. Same-day email replies. In-app chat that resolves most things in minutes. The longest phone wait I've had in six and a half years was 25 minutes. That was my worst, which tells you something.
3. The smart-home upside is real if you've got the kit. I'm on simple Fixed — no EV, no solar, no heat pump. But for households that do have any of those, the tariff range (Go, Intelligent Go, Tracker, Agile, Flux, Cosy) is genuinely the reason to switch, not a marketing flourish.

If one of those three lines is the answer you came for, skip ahead. The rest of this post is the evidence.

My pricing experience over six years

I switched to Octopus in September 2019 on a Flexible Octopus (Economy 7) tariff. I'd been with EDF before that, paying about £80 a month on a standard variable tariff with regular upward adjustments. My first Octopus direct debit was £60. The first bill came in at £60.14 — 25% cheaper from day one, same house, same usage.

Here's how the headline numbers have moved in my actual bills:

Two things to say about that table.

The standing charge has more than doubled. 19.11p/day to 41.59p/day — a 118% increase. That's not Octopus-specific; it's the result of Ofgem's structural decisions on how network costs get allocated, and every UK supplier on the default tariff cap carries it. For context, the Ofgem electricity standing-charge cap for standard-variable direct-debit customers is 57.2p/day between 1 April and 30 June 2026. My Octopus Fixed charge sits comfortably below that.

The unit rate has moved sensibly. The jump from a ~16p day-rate on Flexible E7 to 25p on a single-rate Fixed tariff looks big, but it reflects (a) the post-2022 wholesale reset that shifted the entire UK market, (b) my decision that I don't have enough night load to justify an E7 split any more, and (c) swapping flexibility for the certainty of a Fixed deal. The Ofgem price cap for a typical direct-debit household is £1,641/year between 1 April and 30 June 2026 — down 6.6% on the previous quarter. My bills track in that ballpark.

The tariff journey

I've moved between Flexible and Fixed four times in six years:

The September 2021 Fixed lock is the moment that turned me from a satisfied customer into an evangelist. Wholesale gas prices started climbing that autumn, the Ofgem price cap rose repeatedly through 2022, and Flexible customers across the industry saw bills double or worse. I was locked in on a price set before the crisis. Comfortably several hundred pounds of saving off one decision.

What about gas?

My gas history is messier, because I was with Bulb from late 2018 until Bulb went into special administration on 24 November 2021. When that happened I moved my gas to E.ON Next, and kept that split — Octopus for electricity, E.ON Next for gas — until my second house move in September 2025, when I consolidated everything with Octopus.

That gas split is worth flagging: I've had direct first-person experience of running Octopus and E.ON Next side by side for nearly four years. If you're weighing those two up, the short version is that both are good, both are responsive, and Octopus's app is better. I consolidated with Octopus when the opportunity came up.

Is Octopus cheap?

The honest answer: not always cheapest, consistently competitive. I've compared on Uswitch, Citizens Advice, and direct supplier quotes at every switch point. Octopus has been in the top three every time. For me, that plus the £50 referral credit plus the service quality plus the Octoplus rewards is enough to keep me there. If your decision criterion is "must be the absolute cheapest unit rate on any given Tuesday," you'll find cheaper weeks elsewhere — but you'll give up everything else in return.

Customer service: what actually happens

This is where Octopus differentiates itself from the rest of the UK energy market, and where a review built on six and a half years of actual interactions can say something brochure copy can't.

Two house moves, zero friction. I moved in September 2023 and again in September 2025. Both moves I handled entirely through the Octopus app and web dashboard — entering closing reads at the old address, opening reads at the new one, confirming switch dates. No phone calls, no forms, no chasing. The second move also consolidated my gas from E.ON Next onto Octopus, which I also did online. For anyone who's had a traditional supplier demand three phone calls and a physical form for a move, this is a real quality-of-life upgrade.

The wrong-meter-reading incident. Once in six and a half years I entered a meter reading wrong — off by a decimal point, which produced an unexpectedly high bill. I called customer service, waited 25 minutes (my longest phone wait in 78 months as a customer), and the agent fixed it in two minutes. She was cheerful, apologetic about the wait, and the corrected bill arrived the same day. That's my worst. That's genuinely my worst experience.

Chat and email are the daily drivers. For anything non-urgent, Octopus's email team replies the same day — approximately unheard-of in this industry. The in-app chat, when available, resolves most queries in under five minutes. I've used both probably a dozen times over six years for routine questions and never been left hanging.

Trustpilot has Octopus at 4.8/5 from over 700,000 reviews (as of April 2026), and the Which? Recommended Provider badge has held for nine consecutive years. My lived experience matches those numbers more than it contradicts them — which I say as a customer who has genuine grievances (section 5) and isn't trying to polish the brand.

Tariff range: what I've used vs what I'll summarise honestly

Here's where I have to disclose something most review sites don't. Octopus has one of the deepest tariff ranges of any UK supplier, and I've only used two of them. I've been on Flexible Octopus and Fixed — nothing else. So I'll cover those two in detail from experience, and summarise the rest based on their published terms, because faking authority on something I haven't lived with doesn't serve anyone.

Flexible and Fixed (what I've actually used)

Flexible Octopus is the direct replacement for a standard variable tariff. Price tracks the market with no exit fees. I was on it for roughly three of my six years and it did what it said. Downside is obvious: when wholesale prices rise, your bills rise. Worth it if you want the option to switch out at any time, but in a rising market it's the wrong bet.

Fixed locks your unit rates and standing charge for a defined term (typically 12 or 24 months) with an exit fee if you leave early. I've been on Fixed twice: two years from September 2021 (the pre-crisis lock), and again from October 2024 to now. Both times Fixed was cheaper than Flexible at the point I signed, and both times I chose stability. For a household like mine — no EV, no solar, no heat pump, no shiftable loads — Fixed is the right default. The case for the smart tariffs below gets weaker the flatter your usage curve is.

The tariffs I haven't used (honest-stance summary)

To be clear: what follows is summary, not review. If you want a review of Intelligent Octopus Go from someone who actually charges an EV overnight on it, read a post by someone who does.

• Go — cheap unit rate during a 5-hour overnight window (typically 00:30–05:30). Built for EV owners charging at home. Makes sense if your car does most of its charging overnight.
• Intelligent Octopus Go — the smarter sibling of Go, where Octopus's software takes control of your EV's charging schedule and optimises for grid conditions. Requires a compatible car or charger. Beats Go on price if your EV fits.
• Tracker — unit rate recalculates daily based on wholesale price. For people comfortable with volatility who want to bet on sustained wholesale lows. The admin overhead of watching a daily price doesn't appeal to me, but it's a real saving for people who pay attention.
• Agile — half-hourly pricing, with a new rate every 30 minutes published the day before. Built for households who can genuinely shift load (run the dishwasher at 2am, heat water at noon). If you can't or won't do that, Agile will cost you more, not less.
• Flux — designed for solar + battery households. Pays a higher rate for what you export at peak, charges less for what you import off-peak. Only worth it if you've got the kit.
• Cosy — heat-pump-specific, with cheap-window hours aligned to when heat pumps typically work hardest. For people who've made the heat-pump investment.

If you're in any of those categories, the upside on the right tariff is substantial — often larger than the difference between suppliers on a standard tariff. Which is why people with EVs, solar arrays, and heat pumps are disproportionately Octopus customers. I'm not one of them. When I eventually buy an EV (it's on the list), I'll re-run this calculation and almost certainly move onto Go or Intelligent Octopus Go.

Rewards: Octoplus, spin-the-wheel, Saving Sessions, free-electricity events

These are the bits most reviews bury and I think they're genuinely good.

• Spin the wheel. Every day you can spin a wheel in the app for Octopoints. Typical win is 8 points; occasionally 800. Octopoints convert to bill credit at 800 = £1. Small money, but the daily engagement loop is oddly enjoyable, and over a year it adds up to a real discount.
• Saving Sessions. Octopus pays you account credit for reducing usage during high-demand windows announced by the National Grid (usually a couple of hours on a winter evening). Credit per session is modest if you just dim the lights, but people who leave the house, cook early, and don't run the dishwasher can stack real savings. I participate whenever I see the notification.
• Free-electricity events. Octopus occasionally runs windows where electricity is free. Do your laundry, run the dishwasher, charge anything chargeable — genuine zero-cost hours if you can shift load to them.

None of this is life-changing. None of it is why you'd switch. But it's a set of engineered upsides that other suppliers don't have, and it signals a company that treats customers as people to engage with rather than meter numbers to bill.

What's got worse (or was never right): grievances on the record

Any customer of six years has complaints, and naming them is what separates an honest review from PR copy. Here are mine.

The direct-debit recommendation algorithm is aggressive. Octopus has, on at least one occasion, suggested I move my DD to £160/month when my actual usage supported something closer to £120. The algorithm has a clear bias toward building account credit going into winter, which is financially conservative from Octopus's perspective but chippy from mine. I've always just overridden the recommendation and set my own, and Octopus has always allowed that. But you should know the default recommendation will lean high.

The 2022 crisis direct-debit hikes. Friends of mine who were in debt balance at the peak of the 2022 energy crisis had their direct debits raised substantially without what felt like meaningful consultation. That wasn't my experience — my Fixed lock insulated me — but it happened to people I know, and it was contentious at the time. Protecting the business's cash position during an unprecedented wholesale shock is defensible; how Octopus communicated those specific increases was the weak link.

Chat isn't 24/7. If the in-app chat is closed, you're falling back to email (same-day but not instant) or phone. For most queries that's fine. For the rare genuinely-urgent issue at 11pm it's an unforced gap in the service offering.

And for the record: things that haven't got worse

After six and a half years and growth from roughly one million customers to 7.7 million UK households (Octopus figures, December 2025), here's a short list of what has held up:

• No corporate drift. The tone of communications, the personality of customer service replies, the willingness to admit an error — all unchanged from 2019. That's remarkable at this scale.
• No app regressions. The app has only got better. No dark patterns rolled in, no features removed, no regressions I've noticed.
• Green credentials intact. Octopus's B Corp certification, and its active investment in new renewable generation, remain my trust anchor.
• The £50 referral reward has been stable the entire six and a half years. £50 for me, £50 for the person signing up. Same rate in 2019, same rate in 2026.

Who Octopus Energy isn't for

A review that says "it's great for everyone" is useless. Here's where I'd hesitate.

• If phone is your only support channel and speed matters. I said my worst wait was 25 minutes. You might get better, you might get worse. If you can't use an app or email and you need same-hour phone resolution as a hard requirement, Octopus's digital-first model might not suit you. A big-six supplier with call centres deeper than it can fill may be a better structural fit.
• If you're on a prepayment meter. I've never used one with Octopus and can't speak to the experience. Octopus does serve prepayment customers and reviews from people who do are mixed in both directions. Research independently.
• If you're off-grid, on LPG, or on heating oil. Octopus doesn't supply those. Non-question.
• If you refuse to have a smart meter. The whole Octopus model assumes you're happy with smart-meter data. You can be a customer without one, but you'll miss a lot of the upside — Saving Sessions credit in particular.
• If your sole criterion is the cheapest unit rate on any given week. You'll find cheaper spot prices elsewhere sometimes. Accept the trade-off.

One counter-intuitive point worth making: Octopus is now arguably the safest supplier in the UK. They overtook British Gas as the UK's largest domestic energy supplier around the turn of 2024–2025 (Cornwall Insight data had them ahead by market share in October 2024, confirmed by Ofgem in early 2025), serving approximately 25% of UK households. They weathered the 2022 crisis at a much smaller scale without going bust. If your memory of energy shopping is the post-2021 cull of smaller suppliers — Bulb, Avro, Green, Utility Point, People's Energy, and dozens more all gone — Octopus is the rare scale player you can pick for size reasons as well as service ones. I wouldn't have predicted that in 2019.

Would I switch to Octopus in 2026?

Yes. Without reservation.

The pricing has been fair. Six years, every comparison run, top three. That's enough.

The service is the best I've experienced. I've been a customer of EDF, Bulb, E.ON Next, and Octopus across gas and electricity, and Octopus beats all three on responsiveness and competence. If you've ever been put on hold for 45 minutes to report a meter reading, Octopus will feel like a different industry.

The closest credible competitor is E.ON Next, which I had for gas from 2021 to 2025 — genuinely good, clean app, responsive staff. Still not as good as Octopus across the board, in my experience.

The bonuses make the overall package harder to beat. Even if Octopus weren't marginally cheapest, the £50 referral, the Octoplus rewards, the Saving Sessions credit, and the free-electricity events would keep me. Competitors don't have equivalents yet.

What would make me switch out? Sustained price creep. If Octopus unit rates started consistently coming in above competitors at my switch points and the gap didn't close, I'd go. Six years of track record says they won't let that happen.

Market read for 2026: I don't expect a dramatic shift. Affordability remains what most UK households care about most; the Ofgem price-cap structure flattens the top-end winner-takes-all dynamic; Octopus's growth is if anything accelerating. Pick your supplier by service quality and by tariff fit with your actual household, and for most people Octopus wins on both.

If this review has been useful

I signed up to Octopus through a friend's referral link in September 2019 and I've been sending people mine ever since. Using the link below means you get £50 credit off your first bill (after your first direct debit clears), and I get £50 too — the same £50 you'd get through any other Octopus referral link, just attributed to me. It doesn't change your price or your tariff.
