What Is the Tesla Powerwall 3 Rebate Programme?
The Next Million Powerwall Rebate is Tesla Energy’s initiative to celebrate reaching one million Powerwall installations worldwide. The scheme incentivises UK customers to invest in residential and commercial battery storage by offering cashback rewards that reduce the overall cost of system installation.
Tesla Powerwall 3 represents the latest generation of home battery technology, featuring integrated solar inverter functionality, higher power output, and expandable capacity. This rebate makes the already compelling economics of battery storage even more attractive for UK households looking to reduce energy bills and increase energy independence.
Who Qualifies for the Rebate?
The Tesla Powerwall 3 rebate is available to:
- UK homeowners purchasing new Powerwall 3 units or Powerwall 3 Expansion packs
- Commercial property owners installing qualifying systems
- Customers working with Tesla Certified Installers (such as Infinity Energy Services)
- Properties where installation is completed within the eligible timeframe
One crucial limitation: the rebate is capped at £750 per address, meaning households can claim for a maximum of two units regardless of how many are actually installed.
How Much Can You Save? Rebate Breakdown
Rebate Amounts by Product
The programme offers the following rebates:
- Powerwall 3 (main unit): £375 per unit
- Powerwall 3 Expansion: £375 per expansion pack
- Maximum per household: £750 (equivalent to two units)
Example Rebate Scenarios
Single Powerwall 3 Installation:
One Powerwall 3 unit = £375 rebate
Two-Unit Installation:

Maximising Your Powerwall 3 Investment Beyond the Rebate
The Tesla rebate can be combined with other UK incentives for battery storage:
Smart Export Guarantee (SEG): Earn payments for exporting surplus solar energy to the grid. When paired with solar panels, Powerwall 3 can optimise export timing to maximise SEG revenue.
Reduced energy bills: Store low-cost electricity during off-peak hours (see our guide to The Best Electricity Tariffs for your Renewable Energy Home) and use it during expensive peak periods, cutting bills by 40-70% depending on usage patterns.
Grid services: Participate in emerging virtual power plant programmes that compensate homeowners for providing grid balancing services through their battery systems.
Beyond immediate rebates, Tesla Powerwall 3 delivers ongoing value:
- Energy bill reduction: Average UK households save £500-£1,200 annually on electricity costs
- Energy independence: Reduce reliance on grid electricity and protect against price volatility
- Property value: Battery storage systems can increase home resale value by £5,000-£10,000
- Future-proofing: Prepare for electric vehicle charging and heat pump integration
For most UK homes, a two-unit configuration (either two Powerwall 3 units or one Powerwall 3 plus one Expansion) provides the best balance of:
- Sufficient capacity (27 kWh total) for daily household consumption
- Maximum rebate eligibility (£750)
- Emergency backup power during outages
- Optimal solar energy storage for larger solar arrays
Tesla Powerwall 3 vs Powerwall 3 Expansion: What’s the Difference?
Powerwall 3 (Main Unit)
The Powerwall 3 main unit includes:
- Integrated hybrid inverter (solar + battery)
- 13.5 kWh usable capacity
- 11.04 kW maximum power output
- Complete standalone functionality
- Three solar input strings
Powerwall 3 Expansion
Expansion units provide:
- Additional 13.5 kWh storage capacity
- Must connect to existing Powerwall 3 main unit
- Shares inverter with main unit
- More cost-effective than additional main units
- Up to three Expansion units per Powerwall 3
Rebate Considerations
Both products qualify equally for the £375-per-unit rebate. From a rebate perspective, these configurations are equivalent:
- Two Powerwall 3 main units = £750 rebate
- One Powerwall 3 + One Expansion = £750 rebate
Your Tesla Certified Installer can recommend the optimal configuration based on your solar system size, power requirements, and budget.
Common Questions About the Tesla Powerwall Rebate
Can I claim the rebate on systems purchased before 1 December 2025?
No. Only purchases made between 1 December 2025 and 31 March 2026 qualify for the rebate. Tesla’s communication explicitly states that existing customers with pending 2025 installations should proceed as planned, as delaying provides limited benefits.
What if my installation is delayed beyond 31 May 2026?
Your rebate eligibility will be forfeited if your installation isn’t completed by the deadline. Build buffer time into your schedule and work closely with your installer to avoid delays. Weather, supply issues, and DNO (Distribution Network Operator) approval processes can extend timelines.
Can commercial properties claim the rebate?
Yes. While the programme primarily targets homeowners, commercial properties installing qualifying Powerwall 3 systems are also eligible, subject to the same £750-per-address cap.
Can I transfer my rebate to someone else?
No. The rebate is tied to the specific property address and purchase. It cannot be transferred, sold, or reassigned.
What happens if I move house before receiving my rebate?
The rebate is registered to the property address where the system is installed. Moving house during the claim process could complicate your claim. Contact [email protected] immediately if this situation arises.
How long does the Virtual Visa card remain valid?
Check the terms and conditions provided with your Virtual Prepaid Visa Rewards card for expiration details. Typically, these cards remain valid for 12 months from issuance, but you should use the funds promptly to avoid expiration issues.

Is Now the Right Time to Install Tesla Powerwall 3?
Factors Supporting Installation in the Rebate Window
Immediate savings: The £750 rebate reduces upfront costs by approximately 10-15% on typical two-unit installations.
Rising energy costs: UK electricity prices remain volatile, with standing charges and unit rates significantly higher than historical averages. Battery storage provides protection against future increases.
Solar integration: The Powerwall 3’s integrated inverter makes it ideal for new solar-plus-storage installations or upgrading existing solar systems with ageing inverters.
Grid stability: Increasing renewable penetration on the grid may lead to more frequent localised outages, making backup power capability more valuable.
Considerations Before Installation
Upfront investment: Even with the rebate, battery storage requires significant capital investment (typically £12,000-£14,000 for two-unit systems).
Property suitability: Some properties may have space, electrical infrastructure, or DNO constraints that complicate installation.
Technology evolution: Battery technology continues advancing, though the Powerwall 3 represents current best-in-class for residential applications.
