Tesla has secured regulatory approval to supply electricity across Great Britain, marking a significant expansion of Elon Musk's energy business at a time when the company's vehicle sales are faltering in key markets. The approval represents a strategic pivot toward energy services, even as the electric carmaker faces mounting competition and customer backlash in Europe and the UK.

Breaking Into Britain's Energy Market

Tesla has won formal approval from Ofgem, Britain's energy regulator, to operate as an electricity supplier to households and businesses throughout England, Scotland, and Wales. The licence enables Tesla to compete directly with established energy retailers, though with some important limitations on its business model.

The company cannot offer dual-fuel contracts bundling electricity and gas, meaning customers would need to arrange gas supply separately. Despite this constraint, the approval opens significant opportunities for Tesla to replicate its successful Texas operations, where it operates under the Tesla Electric brand and markets itself as providing "low-cost sustainable electricity" for homes, electric vehicles, and communities.

Tesla's existing business model in Texas includes a "virtual power plant" scheme that has proven popular with customers. The system allows Tesla owners with Powerwall home battery systems to charge their vehicles during off-peak hours when electricity is cheaper, then sell excess stored power back to the grid during peak demand periods. This arrangement provides customers with additional income while helping stabilise the electricity network.

A Different Model in Britain

Britain's approach to Tesla's energy ambitions differs from the American model. Rather than operating its own virtual power plant directly, Tesla will partner with Octopus Energy, an existing household energy supplier, to offer similar services to Powerwall owners in Britain. This arrangement reflects the established structure of the UK energy market and the regulatory requirements for operating within it.

The exact number of Powerwalls Tesla has installed across Britain remains undisclosed, though the company has sold more than 250,000 electric vehicles in the country. The energy business represents a potential revenue stream that could diversify Tesla's income beyond vehicle manufacturing, particularly important given recent market challenges.

Facing Headwinds in Vehicle Sales

The approval for energy supply comes at an awkward moment for Tesla's core automotive business. The company's vehicle sales have deteriorated significantly across the UK and much of continental Europe over the past year, squeezed by intensifying competition and controversy surrounding Musk's political activities.

British sales figures tell a stark story. Tesla's February 2026 deliveries fell 37 percent compared with the same month the previous year, dropping from 3,852 vehicles to just 2,422. This decline has eroded Tesla's market position substantially, with its year-to-date market share now standing at 1.34 percent of the UK market. This places Tesla well behind Chinese competitor BYD, which commands 2.64 percent market share, and significantly behind German manufacturer BMW at 5.43 percent.

The sales deterioration reflects multiple pressures on the brand. Customer sentiment has been damaged by Musk's political involvement, including his prominent support for Donald Trump and his subsequent role leading the "department of government efficiency" before departing in May following disagreements with the president over taxation and spending policies.

Political Controversy Takes Its Toll

Beyond American politics, Musk's actions have alienated customers in Britain specifically. His apparent gesture at Trump's victory rally that observers compared to a Nazi salute, combined with public expressions of support for Germany's far-right Alternative für Deutschland party, drew widespread criticism. Musk has also made inflammatory claims regarding UK politicians, accusing Prime Minister Keir Starmer and other senior figures of covering up grooming gang scandals.

These interventions appear to have triggered a buyer backlash that has materially impacted Tesla's sales performance. In response to declining demand, Tesla launched a lower-priced Model 3 variant in Europe during December, with Musk arguing that affordability would reignite customer interest by broadening the brand's appeal across income levels.

New Model Aims to Revitalise Australian Operations

Meanwhile, Tesla is introducing new products to support its performance in key markets. The company has opened orders for the Model Y L, a stretched three-row variant of its popular Model Y SUV, which is Australia's best-selling electric vehicle. The Model Y L will commence Australian deliveries in the second quarter of 2026.

Priced at $74,900 before on-road costs, the Model Y L costs $6,000 more than the standard Model Y Premium Long Range AWD. The additional investment delivers a six-seat configuration with heated captain's chairs in the second row and a pair of heated third-row seats with ISOFIX mounting points for child restraints. Both rear rows feature ventilation, power adjustment, and USB-C charging outlets.

The Model Y L delivers 681 kilometres of range on the WLTP cycle, a substantial improvement over the 600 kilometres offered by the standard Model Y Premium Long Range. The vehicle features a 378-kilowatt dual-motor all-wheel drive system producing 590 newton-metres of torque, enabling a 0-100 kilometre-per-hour acceleration time of 5.0 seconds.

A notable addition is vehicle-to-load functionality, new to Tesla's Australian lineup. This feature allows owners to draw 3.3 kilowatts of power from the vehicle's battery through an adaptor, potentially powering tools, camping equipment, or other devices. The Model Y L also introduces continuous variable damping suspension with selectable Balanced or Rear Comfort modes.

The Model Y L faces limited competition in the sub-$100,000 three-row electric SUV segment. The Mercedes-Benz EQB and Kia EV9 both start above $90,000 before on-road costs, positioning Tesla's offering as a competitive alternative for buyers prioritising affordability without sacrificing seating capacity.

Strategic Diversification Amid Market Volatility

Tesla's energy sector approval in Britain underscores the company's strategy to diversify revenue streams beyond vehicle manufacturing. As competition intensifies in the electric vehicle market globally, energy services represent a potentially significant and recurring revenue opportunity.

The timing of the energy supply approval, arriving amid visible sales weakness in traditional markets, suggests Tesla is positioning itself for longer-term resilience. Even if vehicle sales remain under pressure from competitive and reputational challenges, energy supply and battery storage services could provide more stable income.

However, success in Britain's energy market will depend on building customer trust and establishing competitive pricing and service advantages over established suppliers. For Australian consumers, the arrival of the Model Y L demonstrates Tesla's commitment to refreshing its lineup and addressing market demands for family-oriented electric vehicles, even as the brand navigates broader challenges in its core business.

Tesla's approval to supply electricity in Great Britain marks a significant strategic expansion, yet it arrives at a moment of genuine vulnerability for the company's vehicle business. Falling sales in Europe and the UK, driven partly by customer backlash over Musk's political activities, have created pressure to diversify revenue. The energy supply business, combined with new product offerings like the Australian Model Y L, represents Tesla's attempt to stabilise its financial performance and broaden its market appeal. Success will require the company to rebuild customer confidence while competing effectively in both energy and automotive sectors.
