📋What Happened to Shell Energy?
Shell Energy's UK domestic energy business was acquired by Octopus Energy and the deal completed on 1 December 2023. Octopus then migrated all 1.3 million Shell Energy home customers to its own systems by 28 March 2024 — a record migration, completed four months faster than any previous transfer of that scale in the UK energy industry.
Shell Energy Retail Ltd was legally renamed Octopus Energy Operations 2 after the acquisition. Shell Energy's broadband arm was separately sold to TalkTalk in February 2024 — a different process from the energy transfer. Shell Energy Business (commercial energy, not home supply) remains a separate active entity.
If you were a Shell Energy home energy customer, you are now an Octopus Energy customer. You would have received transfer letters confirming the migration, and your account details, credit balance, and direct debit were all carried over in full.
⚖️How the Two Suppliers Compared
For context, here's how Shell Energy stacked up against Octopus Energy before the acquisition — and why former Shell customers are better off as a result of the transfer.

✅What Former Shell Energy Customers Should Do Now
As a former Shell Energy customer now on Octopus, there is likely nothing urgent you need to do. Your supply is unaffected. But this is a good moment to check whether your current Octopus tariff is the best available for your circumstances — particularly if you have been defaulted to a standard variable tariff.
- Log in to the Octopus Energy app or website and check your current tariff
- If you have an EV, explore Intelligent Octopus Go — overnight charging can save 68% vs standard rates
- If you have solar panels, look at Octopus Flux for optimised import/export earnings
- If you want wholesale price exposure, Octopus Tracker follows daily wholesale prices
- Sign up to Octoplus — Octopus's free rewards programme — if you haven't already

EV overnight charging at ~7–8p/kWh — AI-scheduled around your departure.
Solar + battery export optimisation — earn from exporting at peak times.
🏆Our Verdict
Former Shell Energy customers ended up with a significantly better supplier. Shell was one of the lowest-rated energy companies in the UK — only 30% of customers would have recommended it, versus 79% for Octopus. The migration brought access to smart tariffs, the Octoplus rewards programme, a 4.8/5 customer rating, and nine consecutive years of Which? Recommended status.
If you're a former Shell customer and haven't yet explored Octopus's tariff range, now is a good time.
