Tesla Powerwall 3 vs GivEnergy AIO
GivEnergy AIO is the British-built rival to Tesla Powerwall 3 — same 13.5 kWh, all-in-one inverter + battery, 12-year warranty. Both are excellent. Here's when to choose which.
Our verdict
GivEnergy wins on UK supply chain (better stock availability, faster part replacement, UK-based support team) and price (typically £400–£600 cheaper fitted). Tesla wins on app polish, Storm Watch, and resale value. For most UK domestic homes either is the right call — choose GivEnergy if availability and price matter; Tesla if ecosystem polish matters.

Frequently asked
Common questions
Why is GivEnergy popular?
UK-built (Newark, Nottinghamshire) means faster part replacement, UK customer support, and shorter wait times. The 12-year warranty is also longer than Powerwall 3's 10 years.
Is GivEnergy as good as Tesla?
For most domestic UK installs, yes. Where Tesla wins is app polish and Storm Watch automatic backup. Where GivEnergy wins is supply chain, price, and three-phase commercial options.
Can I run a heat pump from GivEnergy AIO?
Yes — 6 kW output is enough for a typical 9 kW air-source heat pump (which draws 2–3 kW peak). Powerwall 3's 11.5 kW gives more headroom but most homes don't need it.
