Introduction
The Tesla Powerwall 3 is one of the most advanced home energy storage systems available today. With rising energy bills in the UK, many households are asking: What is the Tesla Powerwall 3 price, and can it be supported under the ECO4 scheme? While ECO4 primarily funds heating and insulation upgrades, understanding how the Powerwall 3 fits into an energy-efficient home can help homeowners make smarter choices.
What is the Tesla Powerwall 3?
The Tesla Powerwall 3 is the latest version of Tesla’s home battery. It is designed to store solar energy and provide backup power during outages. Compared to the Powerwall 2, it offers:
- Higher storage capacity (13.5 kWh and above).
- Better integration with solar panels and heat pumps.
- Smart energy management to reduce costs during peak hours.
Tesla Powerwall 3 Price in the UK
The Tesla Powerwall 3 price in the UK is expected to range between £8,000 – £10,000, excluding installation costs. Once you include installation, cabling, and setup, the total can rise to £11,000 – £12,000.
Factors affecting the cost include:
- Size of the installation (single or multiple Powerwalls).
- Integration with solar panels.
- Local installer charges.
Compared to other home batteries, the Powerwall 3 is premium-priced but offers reliability and efficiency unmatched by smaller systems.

ECO4 Scheme and Energy Storage
The ECO4 scheme is designed to improve home energy efficiency by funding measures like:
- Free boiler replacements.
- Heat pump installations.
- Home insulation (loft, cavity, wall).
At present, ECO4 does not directly fund Tesla Powerwall installations, but it can indirectly benefit homeowners who install a Powerwall by lowering overall energy demand through insulation and heating upgrades.
