If you’ve been considering battery storage, you may have seen that Tesla is currently offering a reimbursement on its latest home battery system, the Powerwall 3.
The offer allows eligible customers to receive £375 per Powerwall 3 or Powerwall 3 Expansion, up to £750 in total. It’s a welcome incentive, but as with any promotion, the details matter.
Here’s what the reimbursement actually involves, who is eligible, and what you should consider before making a decision.
What Is Tesla Powerwall 3?
Powerwall is Tesla’s rechargeable home battery designed to:
- Store excess solar energy for use later in the day or at night
- Reduce reliance on the grid
- Support homes during power cuts
- Optimise how stored energy is used to maximise savings
The Powerwall 3 combines battery storage with an integrated inverter, offering a more streamlined and efficient system for modern solar installations. For homes with higher energy usage, Powerwall 3 Expansion units can be added to increase capacity.
At Sunlit Solar, we design battery systems around the property, usage patterns and long-term goals, not around a product brochure. Tesla Powerwall 3 is one of several premium options we work with when it is the right fit for the household.
How the Tesla Powerwall 3 £750 Rebate Works
Tesla’s current offer provides a reimbursement rather than a discount:
- £375 per Powerwall 3 or Powerwall 3 Expansion
- Up to £750 total (maximum of two units)
- Issued as a Virtual Visa® Reward Card by email
- Not a cash refund and not deducted from your installation invoice
This means you pay for the system as normal, and once Tesla has reviewed and approved your application, the reward card is issued separately.
Key Dates for the Powerwall 3 Rebate
To qualify, your order and installation must fall within Tesla’s defined windows:
Order period:
1 December 2025 – 31 March 2026
Installation and connection period:
1 December 2025 – 31 May 2026
Applications must also be submitted through Tesla’s reimbursement portal by the stated deadlines.
Who Is Eligible for the Tesla Powerwall 3 Reimbursement?
To be eligible for the reimbursement, all of the following conditions must be met:
1. Order and Registration
- Order Powerwall 3 or Powerwall 3 Expansion between 1 December 2025 and 31 March 2026
- Place the order through a Tesla Certified Installer, such as Sunlit Solar.
- Register for the reimbursement on Tesla’s portal by 31 March 2026
2. Installation and Connection
- Have your system installed, connected and registered between 1 December 2025 and 31 May 2026
- Submit your reimbursement request by 31 May 2026
3. Unit Limits
- The reimbursement can be applied to up to two Powerwall units (Powerwall 3 and/or Expansion) per Tesla Account and installation address
4. Payment Status
- Tesla may reject reimbursements where there are overdue invoices on the order
- If a reimbursement is rejected for this reason, the purchase itself remains valid and is not cancelled or refunded
Final eligibility and the reimbursement amount are only confirmed after Tesla has reviewed your application.
What the Powerwall 3 Rebate Is – and What It Isn’t
It’s important to be clear about what this offer represents:
✔ A £375 per unit reward issued after installation
✔ Paid via Virtual Visa® Reward Card
✔ Can be used wherever Visa is accepted, subject to card terms
✘ Not a price reduction on your system
✘ Not cash in hand
✘ Not guaranteed unless all eligibility requirements are met and approved by Tesla
We always recommend viewing this as a bonus, not the primary reason to invest in battery storage.

Is Tesla Powerwall 3 Right for Your Home in Somerset?
Not necessarily.
Battery storage should be chosen based on:
- Your energy usage patterns
- Whether you have or plan to install solar
- Tariffs and time-of-use pricing
- Your goals around grid independence, resilience and long-term savings
Powerwall 3 is a high-quality product, but it isn’t the only solution available. Other manufacturers offer different capacities, control systems and integrations that may be better suited to some households.
At Sunlit Solar, we design each system around the property and the people living in it — not around a one-size-fits-all product.

Our Approach to Battery Storage in Somerset
If you’re considering Powerwall 3 under this offer, we will:
- Confirm eligibility with Tesla before you proceed
- Design a bespoke system based on your home, energy use and future plans
- Handle the installation, registration and aftercare properly
- Ensure you understand exactly how the reimbursement works and what to expect
We won’t recommend a product simply because there’s a promotion attached to it. The system has to make sense for you first.
In Summary
Tesla’s Powerwall 3 reimbursement offers:
- £375 per unit, up to £750 total
- A post-installation reward, not a discount
- Strict ordering, installation and registration deadlines
- Eligibility that must be approved by Tesla
For homeowners already considering battery storage, it can be a worthwhile added benefit, but the long-term value always comes from choosing the right system for your home.
