Tesla’s Powerwall home battery has become one of the most sought-after solutions for household energy resilience and solar integration. To accelerate adoption of the latest Powerwall 3, Tesla is offering a limited-time rebate that reduces the net cost of installation for qualifying homeowners. Whether you’re adding storage to a solar system or installing backup power from scratch, this rebate could markedly improve your return on investment.

Below, we explain what the rebate is, how it works, and how to claim it.

What Is the Tesla Powerwall Rebate?

Tesla’s Powerwall rebate programme — often referred to as the “Next Million Powerwalls Rebate” — provides a cash-back incentive to buyers of the Powerwall 3 and Powerwall 3 Expansion units. The rebate is issued in the form of a Virtual Prepaid Visa Reward Card once eligibility criteria are met.

In the UK, the rebate currently offers:

£375 back per Powerwall 3 or Powerwall 3 Expansion,
Maximum £750 per household (for up to two eligible units).

This promotion aims to celebrate Tesla’s milestone of having one million Powerwalls installed worldwide and to drive further adoption of energy storage solutions.

Who Is Eligible?

To qualify for the rebate, homeowners must meet specific requirements:

Order WindowYou must place your order for a Powerwall 3 or Powerwall 3 Expansion between 1 December 2025 and 31 March 2026.
Registration DeadlineAfter ordering, rebate registration must be completed by 31 March 2026 through Tesla’s online reimbursement portal.
Installation and Final ClaimThe system must be installed, connected and registered between 1 December 2025 and 31 May 2026. Final rebate claims must also be submitted via the portal by 31 May 2026.
Certified Installer RequirementOrders must be placed directly with Tesla or through a Tesla Certified Installer to ensure eligibility.

How the Rebate Is Paid

Once Tesla approves a completed rebate claim, the payment is sent as a Virtual Visa Reward Card by email. This prepaid card can be used anywhere Visa is accepted, subject to terms and conditions — meaning you effectively lower the net cost of your battery storage installation.

Why This Rebate Is Significant

The Powerwall rebate is meaningful for several reasons:

Direct Manufacturer Incentive: Unlike government tax credits or utility rebates, this is a Tesla-funded rebatedesigned to boost early adoption of the latest Powerwall technology.
Enhanced Affordability: Home battery systems have historically had high upfront costs. A rebate of up to £750 improves the economics, particularly when combined with other incentives like the UK’s 0% VAT on home battery storage (available until March 2027).
Flexibility and Backup Power: The Powerwall 3 offers advanced features — including whole-home backup, solar integration and smart energy shifting — that make it valuable beyond just cost savings.

Tips for Claiming Your Rebate

To maximise your chances of successfully receiving the rebate:

Order early in the defined window. Installers may face scheduling constraints as the programme progresses.
Register immediately after ordering. This ensures your eligibility is locked in before the registration deadline.
Verify installation and registration. The rebate requires the Powerwall to be connected and registered — not just physically installed.
Save documentation. Keep all receipts, registration confirmations and portal screenshots in case follow-up is needed.

Tesla’s Powerwall rebate represents a rare opportunity to reduce the effective cost of cutting-edge home energy storage. For installations of Powerwall 3 or Powerwall 3 Expansion between December 2025 and May 2026, qualifying homeowners in the UK can reclaim up to £750, making this an attractive window to invest in resilience, solar optimisation and energy independence.

If you’ve been considering a Powerwall for backup power or to maximise your solar generation, now may be the most financially compelling moment to act.
