Octopus has gained more than 1.9 million customers since Q1 2023, reaching a market share of 22 per cent with 6.8 million households now served by the company.

In addition, 1.3 million households transferred over from Shell Energy Retail following Octopus’ takeover of the business in late 2023.

Octopus is now officially the UK’s largest electricity supplier, achieving this only eight years after launching to the market.

Octopus has also expanded across the world and is now active in 18 different countries, looking after almost 8 million households globally. It is also one of the largest investors in renewables in Europe, managing a portfolio worth £7bn.

Greg Jackson, founder of Octopus Energy Group, commented: “We’ve invested relentlessly in outstanding people and technology to deliver better customer service and lower costs - and today’s news shows that this works. I hope that we can inspire both entrepreneurs and existing companies that by investing for the long-term, and truly focusing on customers, they can deliver success for themselves and for those they serve.”
