The Next Million Powerwall Rebate: Get Up to £750 Back on Powerwall 3

Tesla has reached an incredible global milestone of 1 million Powerwalls installed and to celebrate, UK homeowners can now claim a limited-time rebate worth up to £750 when installing a Powerwall 3 or Powerwall 3 Expansion unit. 

As a Tesla Certified Installer, GHES can help you secure this rebate, making this winter one of the most cost-effective times to upgrade your home with battery storage.

What Is the Tesla Powerwall Rebate?

Between 1 December 2025 and 31 March 2026, customers who order a Powerwall 3 or Powerwall 3 Expansion are eligible to receive:

  • £375 per unit (Powerwall 3 or PW3 Expansion)
  • Up to £750 per installation address
Installations must be completed by 31 May 2026, and customers must submit their claim through Tesla’s official portal. This is a Tesla-funded rebate,  not a Green Home Energy Solutions promotion, meaning the savings come directly from the manufacturer.

Why This Rebate Matters

This incentive makes home battery storage more accessible than ever.
For many homes, it:

  • Accelerates payback on a new system
  • Encourages expanding an existing Powerwall setup
  • Makes winter electricity costs more manageable
  • Reduces reliance on volatile energy prices
Whether you’re adding storage to your solar system or want backup protection, this rebate reduces the upfront cost significantly.

Key Benefits of Powerwall 3

Tesla’s official benefits include six major advantages for homeowners 

  • Energy savings
  • Solar power day and night
  • Energy usage monitoring
  • Backup protection during grid outages
  • Lower reliance on the grid
  • Easy system expansion
These benefits reflect what we see daily in our own installations across Norfolk: long-term savings, improved resilience, and total control over home energy.

Is This the Right Time to Install?

If you’ve been considering battery storage, this is one of the strongest incentives Tesla has ever offered. This rebate is ideal for:

  • Homes wanting to reduce winter energy bills
  • Existing solar customers wanting full self-consumption
  • Households on Cosy, Go, Intelligent or time-of-use tariffs
  • Customers wanting to expand their Powerwall capacity
  • Anyone wanting backup power during outages
The rebate window is strictly limited; once it closes, it won’t return.
