Is a home battery worth it in United Kingdom?

It is financially promising when degraded bill savings comfortably recover the installed price within the warranty. The answer depends on real solar exports, evening use and the spread between import and export rates.

How should I compare battery quotes?

Compare installed price per usable kWh, warranted throughput, inverter power, included electrical work and payback using your own energy data.

The local reality

A battery only earns from energy it actually cycles.

A smart tariff can improve a battery case, but only when the usable capacity, charge windows and export rules match your actual household. We exclude speculative tariff income from the base result.
