Tesla is no longer just a car company. As of March 2026, Ofgem has granted Tesla Energy Ventures Limited a full electricity supply licence for Great Britain. Furthermore, this means Tesla can now sell electricity directly to your home. Moreover, combined with Tesla Powerwall 3 UK home energy systems and the Tesla Wall Connector, your entire home energy ecosystem can now run through one company.
At KindEnergy, we don’t just install Tesla hardware. We help you plug into the new Tesla energy ecosystem in the UK.
🏛️ Tesla Is Now a UK Electricity Supplier
This is the headline that changes everything. Furthermore, after a seven-month Ofgem review, Tesla Energy Ventures’ electricity supply licence approval was confirmed in March 2026.
What This Means:

💷 How Homeowners Save Up to 80% on Energy Bills
This is the question every homeowner asks. Furthermore, the combination of solar, Powerwall 3, and smart tariffs delivers extraordinary savings.
How the Savings Stack Up:
Strategy 1 — Solar Self-Consumption:
Solar panels generate free electricity during the day. Furthermore, Powerwall 3 stores surplus for evening use. Moreover, this alone cuts grid dependency by 50-60%.
Strategy 2 — Cheap Overnight Charging:
Charge Powerwall 3 from solar or cheap overnight tariff rates (as low as 7p/kWh). Furthermore, use stored energy during expensive peak hours (30-35p/kWh). Moreover, this tariff arbitrage saves hundreds annually.
Strategy 3 — Combined Optimisation:
In the right home, combining strong solar generation with cheap night rates and high self-consumption can cut grid import by up to 80%, slashing bills accordingly.
Real-World Savings Example (4-Bed Detached Home):
| Cost Factor | Without Solar/Battery | With Solar + Powerwall 3 |
|---|---|---|
| Annual Electricity Bill | £2,100 | £420 |
| Annual Savings | — | £1,680 |
| Grid Import Reduction | 0% | Up to 80% |
| SEG Export Income | — | £200-£400 |
| Total Annual Benefit | — | £1,880-£2,080 |
Furthermore, Tesla’s own UK rebate campaign offers up to £750 back per household on Powerwall 3 installations in 2025-2026, further reducing upfront costs.
🚗 Tesla Car + Wall Connector + Powerwall = One Ecosystem
This is Tesla’s masterstroke. Furthermore, the Tesla Wall Connector EV charger home system completes the integrated energy loop.
How the Tesla Home Ecosystem Works:
- ☀️ Solar panels generate electricity during the day
- 🔋 Powerwall 3 stores surplus energy
- 🏠 Your home runs on stored solar electricity
- 🚗 Tesla Wall Connector charges your EV from stored solar or cheap overnight rates
- 📱 Tesla App controls everything from your phone
The Tesla Wall Connector:
| Feature | Detail |
|---|---|
| Max Charging Speed | 22 kW (three-phase) |
| Solar Charging Mode | ✅ Yes |
| Powerwall Integration | ✅ Seamless |
| Smart Scheduling | ✅ Via Tesla App |
| Weather-Sealed | ✅ Outdoor rated |
Moreover, your Tesla car and home both run on cheap or free electricity. Furthermore, this eliminates petrol costs while slashing household energy bills.
Virtual Power Plant Potential:
Tesla already runs virtual power plants in Australia and Texas. Furthermore, Powerwalls in thousands of homes act together as a flexible grid asset. Moreover, homeowners are paid for contributing stored energy back to the grid during peak demand.
The new UK licence is a clear step toward replicating this model here. Subsequently, early Powerwall adopters could earn additional income through grid flexibility services.
