Elon Musk’s Tesla could soon be powering homes in the UK after the company was given the green light to launch a household energy supplier in Britain.
The decision to grant the company’s subsidiary, Tesla Energy Ventures, a licence introduces a potentially significant new competitor into the UK energy market, arriving at a time when concerns over escalating utility bills are particularly acute.
Several smaller energy firms went bust over the past few years in the UK, as rising wholesale costs clashed with the energy price cap and left them unable to bridge that gap.
The arrival of a new player in the arena should, in theory, be a boost to British households as greater competition can lead to better tariffs being on offer.
However unlike some energy firms, Tesla will not be offering dual tariffs as it does not have licences to distribute gas, only electricity.
In the UK, the present “big six” suppliers in order of size according to Uswitch are Octopus Energy, British Gas, E.ON Next, Ovo Energy, EDF Energy and Scottish Power.
Currently, households are facing the concern that energy bills could rise from July due to the attacks in the Middle East sending oil prices surging.
Ofgem, the nation’s energy regulator, confirmed that Tesla Energy Ventures, a subsidiary of the electric vehicle giant, has now been approved as an electricity supplier. This approval follows a regulatory process that commenced in July of last year.
The new licence paves the way for the Texas-based company, led by billionaire Musk, to expand its operations in Britain. Tesla intends to leverage its expertise in solar energy and battery storage to directly challenge established providers such as Octopus Energy, British Gas, and EDF.
Tesla Motors Limited, another subsidiary, already has an electricity generation licence in Britain. Some owners of Tesla electric cars use a Powerwall home battery which uses solar energy to charge their vehicles, and excess supply can be sold back into the grid.
Energy prices have surged since the war in Iran, leaving British consumers worried over their bills.
Most British households are protected until July from the immediate impact of higher gas prices on heating and electricity costs, due to regulated tariffs, but the government will come under pressure to provide support if the conflict lasts beyond that period.
Sales of Tesla vehicles in Britain have been in decline in recent years – they fell 8.9% year-on-year in 2025 – amid competition from cheaper Chinese brands and a consumer backlash against Musk’s political outlook.
Earlier this week Elon Musk was named the richest person in the world. He is worth more than the next three billionaires combined, the latest calculations from Forbes show.
The Tesla founder, who bought Twitter, now X, in 2022 and has a vision for making it possible for humans to live on Mars, is now estimated to be worth $839bn (£623bn).
It puts him miles ahead of the nearest competitors, the Google co-founders Larry Page and Sergey Brin, valued at $257bn (£191bn) and $237bn (£176bn).
