Tesla has been reported to have won approval to sell electricity directly to homes and businesses across Great Britain, a regulatory milestone that would turn the electric vehicle maker into a licensed retail energy supplier. The licence, reported as granted to Tesla Energy Ventures Limited, would allow the company to compete with established providers such as British Gas and Octopus Energy, though it comes with a notable restriction: Tesla can sell electricity but not gas, meaning it cannot bundle both fuels into a single household deal.
From Application to Approval in Seven Months
Tesla Energy Ventures Limited, registered at Companies House with company records under number 14676544 and a listed SIC activity of trade of electricity, applied to the Gas and Electricity Markets Authority for an electricity supply licence last summer. Ofgem, the energy regulator, published a formal notice confirming the application and opened a consultation window, while noting it could not share additional details under applicable statutory confidentiality provisions.
The application followed earlier reporting that Tesla was preparing a push into the British retail market. In August 2025, The Guardian revealed that Elon Musk’s company had moved to secure permission to supply electricity to households, describing how the EV manufacturer was seeking to extend its energy ambitions beyond hardware into tariffs for British consumers. That report framed the move as part of a broader strategy to integrate Tesla’s cars, home batteries and potential electricity supply into a single ecosystem.
According to coverage from London, Tesla’s energy business received approval to supply electricity in the UK on 12 March 2026. The Guardian separately reported that Tesla was given the go-ahead to supply electricity in Great Britain on the same date. No official Ofgem notice of grant for the supply licence has been published as of this writing; the confirmation so far rests on these secondary reports rather than the regulator’s own announcement page, and the licence does not yet appear in Ofgem’s public register of licensees.
Ofgem typically adds new licensees to its searchable public register and issues a short decision document once a licence is formally granted. The absence of such a notice suggests there may be a short lag between the regulator’s internal decision and publication. Stakeholders who want to see the official confirmation as soon as it is released can sign up to Ofgem’s email alerts through its subscription service, which distributes updates on new licences and policy consultations.
Tesla Already Held a Generation Licence
The supply licence is not Tesla’s first interaction with British energy regulation. On 12 June 2020, Ofgem granted an electricity generation licence to Tesla Motors Limited under the Electricity Act 1989. That earlier licence covered the production side of the energy chain, allowing Tesla to generate power, but not to sell it at retail to end consumers.
The new supply licence fills that gap. Where the generation licence lets Tesla put electricity onto the grid, the supply licence allows it to bill households and businesses for that electricity. Together, the two licences give Tesla a presence on both sides of the meter in Great Britain, a position that few pure-play EV manufacturers hold anywhere in the world. It also aligns with Tesla’s longstanding narrative that it is as much an energy company as a carmaker, with ambitions spanning solar, storage and grid services.
What the Licence Does and Does Not Allow
Electricity supply licences in Great Britain are governed by standard conditions set by Ofgem, which impose obligations around billing transparency, customer service, complaints handling, and switching processes. Any licensed supplier must meet these requirements before signing up a single customer, including participating in industry data flows and honouring rules on protecting vulnerable consumers.
One clear limitation stands out. According to The Guardian’s reporting on the approval, Tesla’s electricity licence means it cannot offer a dual fuel contract to households in Great Britain. Customers who want a single supplier for both gas and electricity will need to look elsewhere, or maintain a separate gas agreement alongside a Tesla electricity deal. That restriction matters because dual fuel discounts have long been a competitive lever for incumbents like British Gas and EDF. Tesla enters the market without that particular card to play, which could shape how it prices and markets its offering and may push it to focus on all-electric homes and EV owners rather than the broadest possible customer base.
The licence also does not exempt Tesla from the price cap on default tariffs, which limits what suppliers can charge standard variable customers. Nor does it give the company any special treatment on environmental or social obligations, such as contributing to schemes that support renewable generation and energy efficiency. In regulatory terms, Tesla will be treated like any other new entrant.
Why an EV Company Wants to Sell Power
Tesla’s interest in retail energy supply fits a broader corporate strategy that extends well beyond cars. The company already manufactures home battery systems, including the Powerwall, and operates large-scale grid storage projects in several markets. Selling electricity directly to consumers closes the loop: Tesla could, in theory, generate or store power, then retail it to the same households that charge Tesla vehicles in their driveways.
That vertical integration creates a commercial logic that traditional utilities struggle to match. A conventional supplier buys wholesale power and resells it. Tesla could pair supply contracts with hardware sales, offering customers a package that includes rooftop solar, battery storage, and an electricity tariff managed through a single app. Whether the company actually launches such a bundle in Britain remains unclear, as Tesla has not publicly detailed its rollout plans, pricing, or timeline, and neither Ofgem nor the company has set out specific product designs.
The more interesting long-term possibility involves vehicle-to-grid technology, where EV batteries feed stored energy back into the system during peak demand. If Tesla controls both the vehicle battery and the supply contract, it can orchestrate that energy flow and potentially reward customers for participating with lower bills or credits. Few licensed suppliers in Great Britain combine mass-market EV manufacturing with a retail electricity licence in quite this way, which could give Tesla an edge in designing dynamic tariffs and demand response programmes.
Competitive Pressure on Incumbent Suppliers
Britain’s retail energy market has been under strain for years. A wave of smaller suppliers collapsed after wholesale gas prices spiked, and the survivors have faced intense regulatory scrutiny over billing practices and customer service. Into that environment arrives a globally recognised brand with a technology stack that existing suppliers may struggle to replicate quickly.
Still, the competitive threat should not be overstated. Tesla has no track record as a retail energy supplier in Great Britain. Running a supply business means handling credit checks, managing bad debt, complying with the price cap for default tariffs, and staffing a customer service operation that meets Ofgem’s standards. These are operational challenges that have tripped up well-funded startups before. The absence of a dual fuel option also narrows Tesla’s addressable market, since many British households prefer the simplicity of a single supplier for both fuels and may be reluctant to manage separate accounts.
Incumbent suppliers do have reason to pay attention, though. Tesla’s brand recognition among younger, tech-oriented consumers is strong, and the company’s existing hardware ecosystem gives it a distribution channel that traditional energy firms lack. Owners of Tesla vehicles and Powerwalls are natural early adopters for any new tariff, especially if it promises cheaper charging or better integration with home energy management. Competitors may respond by accelerating their own smart tariffs, investing in partnerships with EV manufacturers, or sharpening offers aimed at electrified homes.
What Comes Next
The immediate next step is for Ofgem to publish the formal licence grant and add Tesla Energy Ventures Limited to its public register, providing official confirmation of what Reuters and The Guardian have already reported. After that, attention will turn to how quickly Tesla moves from licence holder to active supplier, and whether it chooses to launch with a narrow, technology-focused tariff or a broader mass-market offer.
For British consumers, the arrival of Tesla as an electricity supplier is unlikely to transform bills overnight. But it does signal that the line between carmakers, technology companies and energy utilities is continuing to blur. As more households adopt electric vehicles and smart home technologies, the value may lie less in individual products and more in how seamlessly they are stitched together. On that front, Tesla now has the regulatory permission it needs to try to deliver on its long-promised energy vision in Great Britain.
