Tesla Gains Licence to Supply Electricity in Great Britain

Elon Musk’s Tesla has received approval to supply electricity to homes and businesses across Great Britain, marking a significant expansion of the company’s energy ambitions and introducing a new competitor to the UK energy market. The move, approved by energy regulator Ofgem, allows Tesla to replicate a business model similar to its operations in Texas.

Ofgem Grants Tesla Electricity Supply Licence

Ofgem formally granted Tesla Energy Ventures Limited an electricity supply licence on March 12, 2026, enabling the company to provide electricity to domestic and business premises in England, Scotland, and Wales [Source: The Guardian]. The application process began in July 2025 and concluded with the licence taking effect on Wednesday evening [Source: City A.M.].

Replicating the Texas Model

Tesla intends to mirror its successful “Tesla Electric” model from Texas, offering customers the opportunity to power their homes, electric vehicles, and communities with low-cost, sustainable electricity [Source: The Guardian]. However, Tesla’s licence does not permit it to offer dual fuel contracts, meaning customers will need separate tariffs for gas supply.

Virtual Power Plant Integration

Tesla already operates a “virtual power plant” concept, allowing Tesla owners to charge their cars cheaply and sell stored electricity back to the grid through Powerwall home batteries. In Great Britain, this functionality is currently offered in partnership with Octopus Energy [Source: The Guardian]. While the number of Powerwalls sold in Britain remains undisclosed, Tesla has sold over 250,000 electric vehicles in the country.

Market Context and Challenges

Tesla’s entry into the UK energy market comes at a time of heightened consumer concern over rising energy prices, exacerbated by the war in Iran [Source: The Independent]. Most UK households are currently protected from immediate gas price increases due to regulated tariffs, but government support may be required if the conflict continues beyond July. Despite this, Tesla has faced declining vehicle sales in the UK and Europe, falling 8.9% year-on-year in 2025, due to increased competition from Chinese brands and consumer reactions to Elon Musk’s public statements [Source: The Independent].

Compliance and Oversight

As a licensed supplier, Tesla Energy Ventures must adhere to standard sector conditions, including consumer protection, fair customer treatment, financial responsibility, billing transparency, and operational capability [Source: City A.M.]. Ofgem will monitor Tesla’s compliance and retain enforcement powers, including the ability to issue directions or fines if necessary.
