The Next Million Powerwall Rebate - you can get up to £750 back for your Tesla Powerwall installation: Find out more
A major shift in the UK energy market could soon give homeowners far more control over how they buy, store, and sell electricity.
Electric vehicle and clean energy company Tesla has been granted a license by the UK energy regulator Ofgem to supply electricity directly to homes and businesses across Great Britain.
The move marks a significant expansion of Tesla’s energy division, and could accelerate the growth of solar panels and home battery systems such as the Tesla Powerwall 3.
For UK homeowners already considering solar and battery storage, this development could be an important sign of where the energy market is heading.
Tesla is best known for its electric vehicles, but the company has spent the past decade building a growing energy business that includes solar panels, battery storage, and grid services.
With its new electricity supply license, Tesla can now sell electricity directly to households in England, Scotland and Wales.
This effectively places the company in competition with major UK energy suppliers such as British Gas, EDF Energy, and Octopus Energy.
This strategy is not just about selling electricity. Tesla aims to integrate electricity supply with its existing technologies including solar systems, EV charging, and home battery storage.
In other words, Tesla is trying to build a fully integrated home energy ecosystem.
At the centre of this strategy is battery storage.
Products like the Tesla Powerwall allow homeowners to store electricity generated by solar panels or imported from the grid using cheaper periods. This stored energy can then be used in the evening, when electricity prices are typically higher.
In some cases, stored energy can even be exported back to the grid when demand is high.
This type of system creates what is known as a ‘virtual power plant’. Thousands of homes with battery storage effectively become a decentralised power station, helping to balance the grid during periods of high demand.
For homeowners, this can mean greater energy independence and potentially lower electricity bills.
The timing of Tesla’s entry into the UK energy market is significant.
Energy prices have remained volatile in recent years, with global tensions and supply disruptions continuing to affect costs.
As a result, many homeowners are looking for ways to reduce their reliance on the grid.
Solar panels combined with battery storage are increasingly seen as a solution. Solar panels generate electricity during the day, while batteries store any excess energy for use later in the evening, when demand is higher.
This allows households to increase how much of their own electricity they use rather than exporting it back to the grid.
Tesla’s move into the UK electricity supply market signals a broader shift in how energy may be produced, stored and sold.
Instead of relying solely on large centralised power stations, the future energy system may be made up of thousands of smaller energy assets - solar panels, batteries, and electric vehicles – all connected through smart software.
Homes could effectively become small power stations, generating and storing electricity while also supporting the national grid when needed.
For homeowners installing solar today, adding battery storage is increasingly becoming a key part of that system.
Across the UK, more solar panel installations now include battery storage as standard. When combined with solar panels, batteries help maximise the value of the electricity your system generates. Instead of exporting surplus energy during the day and buying it back later at a higher price, homeowners can store that energy and use it when they need it most.
We design and install high performance solar and battery systems, built around premium equipment including the Tesla Powerwall 3.
As developments like Tesla entering the UK electricity market show, the energy system is evolving rapidly. Homes that generate and store their own electricity will be in the strongest position to benefit from these changes.
By combining solar panels with intelligent battery storage, homeowners can reduce their reliance on the grid, protect themselves from rising energy costs, and take greater control over how they power their homes.
