Why Choose Octopus Energy
When you're comparing energy suppliers, it's easy to get lost in the jargon. So let's keep it simple. Here's why Octopus keeps winning awards and why customers actually stick around:
Award-winning customer service that actually picks up
In May 2025, the Energy Consumer Satisfaction Survey rated us 89%, putting us light years ahead of the competition. This is because we put our customers first. The days of waiting on hold as you are passed between a hundred different departments are over. We train our energy experts to ensure they know Octopus inside and out, so chances are one person can solve your query from start to finish. We typically answer calls in just over 2 minutes and respond to emails within two days, and we’re available 7 days a week on social media. We'll always be here when you need us.
We're the UK's most awarded energy supplier, winning almost twice as many awards overall as the next best supplier in 2024.
Transparent pricing
We firmly believe customers shouldn't have to switch every year to get a great deal. That's why we focus on great value for the long term. The average Octopus customer who fixed with us in 2016 and stuck on Flexible Octopus ever since would've saved £1,456 by now compared to another large legacy supplier.
We're the only large supplier that's always priced our standard tariff meaningfully below the Ofgem Energy Price Cap and we keep our standing charges lower than other large suppliers. Plus, our smart tariffs help thousands of customers save even more by using energy when it's greenest.
No hidden loyalty penalties. No sneaky price hikes when you're not looking. And if you want to leave? You have total freedom because most of our tariffs have no exit fees.
Built different, built to last
Octopus Energy started from the bottom in 2015 and has worked its way up to the top spot in less than a decade. But being big isn't the point. It's how we got here that matters.
With the energy sector in crisis, and countless suppliers going bust, we’re here to stay. And we’re committed to doing things right. That means providing the best deals possible, and making sure customers are getting the most out of our smart tariffs, tech and special offers. This mission is why TIME Magazine named us one of the world's ‘100 Most Influential Companies'. From our Free Electricity scheme to all of our Octoplus perks - we do things differently.
Being Britain’s most awarded energy supplier isn’t just about providing the cheapest energy we can. It's about transforming the industry into one that works for everyone.
Rewards that count
With Octoplus, our free rewards programme, the average smart meter customer could get £100's worth of perks every year. We're talking:
- Free weekly coffee at Greggs or Caffè Nero
- Discounted cinema tickets 2 for £8 at Vue Cinema
- 25% off at restaurant chains like Harvester and Stonehouse
- 2-4-1 Ice Skating tickets
- Discounts on Zoo tickets and more.
From January to September 2025, customers claimed Octoplus perks worth millions, including discounted dinners and movie tickets, free Greggs treats, free movie streaming, and over three million free hot drinks. And sometimes we give away really big stuff; like giving away 6 Electric cars to customers who joined in our app game Octoplus SNAP! or our Free Electricity sessions.
In fact, in 2025 customers have used £3,607,813 of free power through free electricity sessions and won £200,000+ worth of prizes, including £30k for 7 amazing charities. Every customer gets to Spin the Wheel, meaning every meter reading gives you a chance to win prizes up to £512, and Octoplus customers can win up to £1000. Plus, customers can take part in our Saving Sessions to get paid to shift their energy use during peak times.
Clean investment that actually makes a difference
Octopus Energy Generation is one of Europe's largest investors in renewable power, with a combined asset value of £6.8 billion. This includes 4.4GW of renewable electricity over 270 large-scale green energy projects and thousands of small-scale assets, spanning 10 countries. As of December 2024, 2.6 million homes are powered annually by assets we manage.
Energy shouldn’t just power your home, it should power your community.
Through the Octopus Fan Club, communities who live closest to our turbines get their power up to 50% cheaper when the turbines are working hardest. The Collective, also allows people to invest directly into green energy projects, allowing customers the benefits of renewable production in real time.
We're not stopping there, we also started 'People Power' to make fundraising ridiculously easy. It lets charities, schools and community groups get £50 for their cause every time someone switches to Octopus using their unique link. The person who switches gets £50 energy credit too and so far, we've donated over £17k to various charities
It's community power in action.
Building the smart grid of tomorrow
The UK's ancient energy system was built around fossil fuels. It’s an outdated system that wasn’t built for the renewables of the future. That’s why we're laying the groundwork for a smarter, greener grid, capable of intelligently supporting the natural flows of sun and wind power.
We're not waiting for someone else to fix the energy system. We're building a new system ourselves.
Fixed, flexible & smart tariffs - find your perfect fit
Fixed or Flexible?
Deciding between the certainty of a Fixed tariff where the unit rates stay the same throughout your contract, or our Flexible tariffs, where your unit rates change depending on the wholesale price of energy?
Watch our two minute tariff guide to help you decide:
Ready to go smart?
Forget boring, one-size-fits-all energy. We've built tariffs that work with how you actually live. Our smart tariffs allow customers to save by shifting their energy use to times when renewable energy is most abundant.

Customer love and care
A team that actually knows their stuff
We've spent years putting together a super-capable, super-friendly team. We train each of our energy experts to ensure they know Octopus inside and out, so they can support you, no matter what your question is. That's what made us the UK's most trusted energy supplier with 4.4 stars from over 700,000 Trustpilot reviews.
Each team functions like its own micro-business, completely responsible for looking after a group of customers, so even in a business of 10 million customers, you're going to speak to the same small team of people every time. No getting passed around. Just real people who actually remember you. Meet the London Team, for an example on how we work.
And a team who genuinely care
When one of our customers lost her husband, our team sent flowers, an electric blanket and made sure her bills were more manageable. When another customer was going through a difficult patch, our call handler personally sent flowers to lift her spirits. We share free electricity with customers on windy weekends when there's plenty of renewable energy to go around. These moments happen all the time. They're simply what happens when you build a company that sees customers as people, not account numbers. Treating people with kindness shouldn't be remarkable, but we're glad these stories remind everyone what's possible.
Don't just take our word for it. Here's what real customers have told us recently:
The team was super communicative and the engineers who came to my home were excellent. They were neat, tidy, and really thorough. Nothing was too much trouble for them.
Kevin, from SurreyI have struggled with debt but Octopus have treated me as a human being rather than just a debtor with an account number. Thank you, I will be eternally grateful!
Cherry, from BristolThe Octopus team were incredibly kind, polite, and professional. When the engineers came they even planted a beautiful plant in our garden on their last day!

What if I don't know which tariff to choose?
Watch our two-minute tariff guide to help you decide between Fixed tariffs (rates stay the same), Flexible tariffs (rates change with wholesale prices) or smart tariffs. Our team can also help you choose - call us on 0808 164 1088.
What happens if I'm in credit or debit my old supplier?
f you’re in credit, your old supplier will transfer the credit directly to your bank account once you’ve received your final bill.
If you’re in debit, you need to clear it as soon as possible, otherwise they might object to your transfer (which can cause delays to your move). If you’re having trouble paying, you can ask for a payment plan, which will still allow you to switch.
Contact us at hello@octopus.energy or call 0808 164 1088 and our team can help. We'll work out the best way forward for your situation.
