Renewables: Why Tesla Wants to Compete with UK Energy Firms

Tesla has formally applied to the UK’s energy regulator Ofgem for a licence to supply electricity directly to households and businesses across England, Scotland and Wales.
The application, signed by Andrew Payne who runs Tesla's European energy operations, was filed in late July 2025 and could see the company compete with established UK energy suppliers as early as 2026.
If approved, Tesla would serve households and businesses across England, Scotland and Wales, leveraging its existing solar energy and battery storage operations to do so.
From cars to kilowatts
Tesla’s energy arm already has a presence in the UK through its sales of solar technology and battery storage units.
More than 250,000 Tesla electric vehicles and tens of thousands of home battery systems are now in British households.
This base could provide an immediate customer network for an energy supply service.
The company operates a similar model in the US through Tesla Electric, a Texas-based supplier that offers discounted charging for Tesla owners and pays customers for feeding surplus electricity back into the grid.
Tesla’s infrastructure advantage could be reinforced by the growing interest among UK consumers in decentralised energy systems, where households not only consume power but also generate and store it.
This model can help balance demand on the national grid, particularly as more homes install renewable energy systems.
Falling car sales
Tesla’s bid for a UK electricity licence comes during a downturn in its European car sales.
Registrations of Tesla vehicles in the UK dropped by almost 60% in July, while German sales fell by more than 55% in the same period.
Across 10 major European markets, sales declined by 45%, driven partly by increased competition from rival manufacturers, like China's BYD.
By building an energy business, Tesla can tap into both commercial and residential markets, offering integrated products that link its hardware with its supply services.
Beyond commercial reasons, public perception is also a factor.
Another factor in Tesla’s falling sales and share prices has been Musk’s growing influence in global politics.
His close ties with US President Donald Trump and posts on his social media platform X have all contributed to his fall from favour with the general public, some of whom have decided to boycott his products as a result.
Elon Musk’s interest in British politics
Although much of Musk’s political activity centres on the US, he has been vocal about the UK in interviews and on social media.
He has described the country as a “police state” run by a “tyrannical government”, criticising policies on asylum seekers and migrants and objecting to the Online Safety Act.
Such comments could complicate Tesla’s path into the UK energy market.
While Ofgem’s licensing process focuses on operational and financial suitability rather than political alignment, Musk’s profile means public and political reactions could play a role in how the move is received.
In response to Musk’s views on UK politics, former Homelessness Minister Rushanara Ali said that the country would have to tighten its regulations around foreign interference.
“Although it is clear that foreign donations to political parties and other campaigners are illegal, the Government recognise the continued risk posed by actors who seek to interfere in our democratic process,” she said.
“The current rules no longer match the sophistication and perseverance of those who wish to undermine our laws, and that threat must be addressed through stronger safeguards.”
