Martin Lewis is the founder of MoneySavingExpert.com, the UK's leading consumer money-saving website, and a regular television personality best known for his ITV primetime show The Martin Lewis Money Show. His energy advice is followed by millions of UK households, and when he speaks positively about a supplier, it carries significant weight.
Unlike comparison sites that earn commission for every switch, Martin Lewis's primary interest has always been the consumer. He regularly surveys his audience directly and publishes the results — which makes his data about supplier satisfaction particularly credible.
"Octopus has a really high customer-service rating in polls I've done."

It's worth noting that Martin Lewis is careful not to name individual suppliers as his top pick — he prefers to encourage comparison. However, Octopus Energy consistently features among the recommended suppliers on the MoneySavingExpert Cheap Energy Club, and Martin has given them a 3.5 out of 5 star MSE rating — one of the highest in the industry (ratings are based on Citizens Advice data and MSE's YouGov polls).
Martin consistently highlights that choosing a supplier with no exit fees gives you flexibility to switch again if prices drop — which Octopus's fixed deals typically offer.
Martin regularly rails against opaque billing. Octopus is known for clear, easy-to-understand bills and real-time usage data via their app.
Martin has specifically mentioned Octopus's Agile tariff, noting that flexible-tariff customers can save significantly by shifting usage to off-peak periods.
Which? — another source Martin frequently references — has named Octopus a recommended provider for nine consecutive years, a streak unmatched in the sector.
Martin's general energy advice as of early 2026 breaks down as follows — and here's how Octopus measures up against each point:
| Martin's Advice | How Octopus Delivers |
|---|---|
| Compare fixed vs variable tariffs | Octopus offers both — Flexible Octopus (variable) and multiple fixed terms ✅ |
| Look for no exit fees | Most Octopus tariffs carry zero exit fees ✅ |
| Check unit rates vs price cap | Octopus fixed rates are regularly at or below the price cap level ✅ |
| Pick a supplier with good service (don't just chase the cheapest) | Octopus tops customer satisfaction surveys year after year ✅ |
| Consider smart tariffs if usage is flexible | Agile Octopus offers half-hourly pricing, sometimes negative unit rates ✅ |
Martin Lewis has praised Octopus Energy for having 'a really high customer service rating' in polls he's conducted, and for 'schooling other big providers' on communication during the energy crisis. He does not officially endorse any single supplier but speaks positively about Octopus's service and innovative tariffs.
Martin Lewis does not make specific supplier recommendations — his advice is always to compare your own options. However, Octopus features strongly on MoneySavingExpert, and Martin has noted their service and tariff flexibility positively on multiple occasions.
With the Ofgem price cap dropping to £1,641 in April 2026, Martin Lewis advises checking whether a no-exit-fee fixed tariff is available close to or below the cap. If it is, locking in provides protection if prices rise again — and with no exit fee, you can still switch if they fall.
Yes. Octopus Energy is Ofgem-regulated with over 7 million UK customers. They have never collapsed or left customers stranded during the energy crisis, and their Trustpilot and Which? ratings are consistently among the industry's best.
