Two of the most-fitted UK home batteries. Both LFP, both well regarded. The pick comes down to capacity, integration and where you sit on the Tesla brand question.
Tesla Powerwall 3 ships 13.5 kWh useable in one box, including the inverter. GivEnergy's 5.2 kWh unit pairs with a separate Gen3 hybrid inverter and is designed to be stacked up in stages. Powerwall suits households wanting one large unit fitted once; GivEnergy suits households who want to phase capacity over time and value UK-based support. Get current fitted quotes for both before deciding — installed pricing moves often and is best checked directly with installers.
