Keep reading to find out: what is the Tesla Powerwall rebate, everything you need to know about the Tesla Powerwall, and how to claim.
What is the Tesla Powerwall rebate?
A rebate is similar to an ordinary sale or discount, but instead of reducing the price before you pay, it gives you some of the money back after you pay.
- When you order a Powerwall 3 (or a Powerwall 3 Expansion) between 1 December 2025 and 31 March 2026, you automatically become eligible for Tesla’s rebate scheme.
- The rebate is £375 per Powerwall 3 (or expansion), and you can claim for up to two units per installation address. That equates to a maximum saving of £750 through reimbursement.
- The rebate is delivered as a Virtual Visa® reward card after installation. The prepaid Visa, complete with unique numbers, is delivered via email and can be used anywhere that Visa is accepted, both online and by phone.
What are the benefits of a Tesla Powerwall 3
The Tesla Powerwall 3 is the most popular battery on the market, and for good reason. Here’s what you could benefit from by taking advantage of this rebate:
1. Lower energy bills through reduced reliance on the grid
Batteries allow you to store electricity whenever you decide to charge it. This means you could use low-cost, off-peak electricity at peak hours. Or, better yet, use your own clean energy – generated throughout the day with solar panels – long after the sun goes down.
2. Automatic backup during power cuts
In a power cut, a Powerwall 3 can keep your home running as if nothing happened, switching over to it’s stored power automatically until the grid is back up and running. Whether it’s winter storms, local faults or unexpected outages, it steps in instantly to power essential appliances – no manual switching required. When the grid comes back, it automatically reconnects and recharges itself.
3. Powerful storage for busy, energy-intensive homes
With up to 13.5 kWh of storage and 11.04 kW of power output, the Powerwall 3 can handle the demands of most UK households. From cooking and laundry to EV charging and evening peak use, you’ll have enough stored energy to keep your home running smoothly day and night.

Once the request is submitted, Tesla will confirm the details and send you the reimbursement within 10 weeks.
