We were the first installers of Tesla Powerwall in the UK. Here’s why we’re proud suppliers and installers of Powerwall for our customers.


Tesla Powerwall is an energy game-changer. The same ground-breaking Tesla battery technology that has revolutionised the electric car market is now available to power your home.

The best battery storage available

Powerwall empowers homeowners to store clean solar energy for use round-the-clock and incorporates all the smart technology you’d expect from Tesla. With Backup Gateway, homes and businesses are protected from power cuts, which are becoming all too frequent due to the strain on our national grid in the ever connected world. Solar panels – without the addition of a Powerwall – will shut down during a power cut for the safety of the grid. However – teamed with a Powerwall system – solar panels continue to produce energy during an outage.

This feature makes it an attractive option for homeowners and businesses needing to keep freezers frozen, lights on and zoom meetings connected during grid outages. Powerwall owners can also take advantage of new agile clean energy tariffs, charging from the grid at the cheapest rate. The Powerwall will even stay one step ahead of the weather but more on that later.

The key benefits of Tesla Powerwall

Powerwall: The Tech

Each Powerwall has a 13.5kWh energy storage capacity, sufficient to power most homes during the evening using electricity generated by solar panels during the day. Multiple batteries may be installed together for homes with greater energy needs.
