Tesla has been approved to supply electricity to UK homes and the company already has thousands of customers waiting

In a move that might surprise its EV fans, Tesla has been approved to supply electricity to UK homes – and the company already has a serious waiting list.

That major green light means the EV giant can now move into Britain’s retail energy market and start supplying power to domestic and business customers across England, Scotland, and Wales.

It is a huge step for the company as it pushes further beyond cars and deeper into the world of home energy, batteries, solar tech, and charging.

And with a loyal base of EV drivers and Powerwall owners already in place, the company could have a ready-made audience from day one.

Tesla has been approved to supply electricity to UK homes

The approval for the tech came from Ofgem.

The UK energy regulator confirmed that Tesla Energy Ventures Limited has been granted an electricity supply license after a seven-month application and assessment process that ran from July 2025 to March 2026.

The license officially took effect on Wednesday evening and allows Tesla to supply electricity to homes and businesses across Britain, although it does not currently cover gas.

That makes this a big moment for Tesla’s wider energy ambitions.

The company already sells Powerwalls, solar technology, and EV chargers in the UK, so this is not a totally fresh start.

Instead, it looks more like the EV company is adding another piece to a much bigger ecosystem that could let customers power their homes, charge their cars, and even send surplus solar energy back to the grid.

The company already has thousands of customers waiting

That is where things could get really interesting.

The Musk-led brand already has thousands of home battery customers in Britain, as well as a large number of EV owners.

This means that there may already be plenty of people ready to sign up if the company launches a UK version of its electric service.

In Texas, that offering lets customers charge their EVs more cheaply and get paid for exporting extra electricity, so a similar model in Britain could prove seriously tempting.

It will not all be easy, though.

Britain’s energy market is tightly regulated, fiercely competitive, and known for razor-thin margins, so the EV company is stepping into a tough space.

But if any company knows how to turn an existing fanbase into a waiting list, it is Tesla.
