GBP-Wired-by-Jessops-2026-7.webp

Tesla recently installed its one millionth Powerwall. To mark that milestone, they’ve launched the Next Million Powerwall Programme, which offers customers a chance to claim a rebate.

Order and install a Powerwall 3 or Powerwall 3 Expansion before the deadline, and you could receive a Virtual Visa® Reward Card worth up to £750 sent straight to your inbox.

As a Tesla Approved Installer, we can help you claim every penny of it.

What Is the Rebate for Powerwall 3?

The programme offers £375 per qualifying unit, up to a maximum of £750 across two units per Tesla account. 

Once your installation is approved, Tesla sends a Virtual Visa® Reward Card by email. You can spend it anywhere Visa is accepted, including online, in-store, and via Apple Pay, Google Pay and Samsung Pay.

Key Dates to Know

The offer runs to strict deadlines, so it’s worth getting moving soon:

  • Order by: 30 June 2026
  • Installation, connection & registration by: 31 August 2026
  • Portal registration deadline: 30 June 2026
  • Reward issued: within 10 weeks of approval

Orders must be placed through a Tesla Certified Installer like Wired by Jessops, and you’ll need to register through the official Tesla rebate portal at teslaenergyrebate.com.

How To Claim a Tesla Powerwall Rebate?

1. Get a Free Consultation and Place Your Order

Book your visit with us before 30 June 2026. Joe personally comes to your home to assess your property and design the right system. Your signed sales contract with us is what triggers your eligibility, so keep it safe.

2. Register on the Tesla Rebate Portal

Once your order is placed, head to teslaenergyrebate.com and register by 30 June 2026. The email address you use must match your Tesla account. You’ll upload your sales contract at this stage.

3. Have Your Powerwall Installed and Connected

We take care of the full installation. Your system must be installed, connected to Wi-Fi and registered in the Tesla app by 31 August 2026.

4. Submit Your Final Claim

Return to the portal and upload your proof of payment along with your Powerwall’s serial number (found in the Tesla app under Settings > My Home Information > My Products > Serial Number). Submit by 31 August 2026, and your reward card will follow within ten weeks of approval.

Is Tesla Powerwall 3 Worth the Money?

While electricity prices in the UK remain high, a Powerwall 3 can significantly reduce your bills. It stores your surplus solar energy during the day and deploys it at night, during a power cut, or whenever grid prices peak.

Paired with a time-of-use tariff like Octopus Intelligent, which we can help set up as Octopus Trusted Partners, many of our customers find their system pays back far sooner than they expected.

Add up to £750 back on top of that, and the case for acting now is hard to argue with.

Why Choose Wired by Jessops?

Using a Tesla Certified Installer is a requirement of the rebate programme. But beyond eligibility, we offer a personal service that larger national companies can’t. Joe visits every single customer in person before producing a quote.

We’re based in St Agnes and cover all of Cornwall and parts of Devon. We’ve been named Renewable Company of the Year, and every installation comes with a 5-year workmanship warranty, annual maintenance, remote monitoring and full HIES deposit protection.
