Sky News can exclusively reveal that Octopus Energy is close to hiring investment bankers to help formally separate Kraken Technologies from the rest of the group.
The demerger, which would be expected to take place in the next 12 months, would see Octopus Energy’s existing investors given shares in the newly independent Kraken business.
A minority stake in Kraken of up to 20pc is expected to be sold to external shareholders in order to help validate the technology platform’s valuation, according to insiders.
One banking source said that Kraken could be valued at as much as $14bn (£10.25bn) in a forthcoming demerger.
Citi, Goldman Sachs, JP Morgan and Morgan Stanley are among the investment banks invited to pitch for the demerger mandate in recent weeks.
A deal will augment Octopus Energy chief executive Greg Jackson’s paper fortune, and underline his success at building a globally significant British-based company over the last decade.
Octopus Energy now has 7.5m retail customers in Britain, following its 2022 rescue of the collapsed energy supplier Bulb, and the subsequent acquisition of Shell’s home energy business.
In January, it announced that it had become the country’s biggest supplier – surpassing Centrica-owned British Gas – with a 24% market share.
It also has a further 2.5m customers outside the UK.
Sources said a £10bn valuation of Kraken would now imply that the whole group, including the retail supply business, was worth in the region of £15bn or more.
That would be double its valuation of just over a year ago, when the company announced that it had secured new backing from funds Galvanize Climate Solutions and Lightrock.
Shortly before that, the former US vice president Al Gore’s firm, Generation Investment Management, and the Canada Pension Plan Investment Board increased their stakes in Octopus Energy in a transaction valuing the company at $9bn (£7.2bn).
Kraken is an operating system which is licensed to other energy providers, water companies and telecoms suppliers.
It connects all parts of the energy system, including customer billing and the flexible management of renewable generation and energy devices such as heat pumps and electric vehicle batteries.
The business also unlocks smart grids which enable people to use more renewable energy when there is an abundant supply of it.
In the UK, its platform is licensed to Octopus Energy’s rivals EON and EDF Energy, as well as the water company Severn Trent and broadband provider Cuckoo.
Overseas, Kraken serves Origin Energy in Australia, Japan’s Tokyo Gas and Plentitude in countries including France and Greece.
Its biggest coup came recently, when it struck a deal with National Grid in the US to serve 6.5m customers in New York and Massachusetts.
Sources said other major licensing agreements in the US were expected to be struck in the coming months.
Kraken, which is chaired by Gavin Patterson, the former BT Group chief executive, is now contracted to more than 70m customer accounts globally – putting it easily on track to hit a target of 100m by 2027.
Earlier this year, Mr Jackson said that target now risked being seen as “embarrassingly unambitious”.
Last July, Kraken recruited Amir Orad, a former boss of NICE Actimize, a US-listed provider of enterprise software to global banks and Fortune 500 companies, as its first chief executive.
A demerger of Kraken will trigger speculation about an eventual public market listing of the business.
Its growth in the US, and the relative public market valuations of technology companies in New York and London, may put the UK at a disadvantage when Kraken eventually considers where to list.
One key advantage of demerging Kraken from the rest of Octopus Energy Group would be to remove the perception of a conflict of interest among potential customers of the technology platform.
A source said the unified corporate ownership of both businesses had acted as a deterrent to some energy suppliers.
Kraken has also diversified beyond the energy sector, and earlier this year joined a consortium which was exploring a takeover bid for stricken Thames Water.
This weekend, Octopus Energy declined to comment.
