A home battery lets you store electricity — from solar, or from cheap off-peak tariffs — and use it later, cutting your bills and giving you some resilience. Here’s what installation involves.
What a battery does
It charges when power is cheap or your panels are generating, then discharges to run your home in the evening or at peak times. Some systems also provide backup power during an outage.
The electrical work
- An inverter/charger to move power in and out of the battery.
- A protected connection to your consumer unit, with isolation.
- Metering and controls so it charges and discharges intelligently.
- DNO notification and certification of the installation.
Do you need solar?
No — a battery works without solar by charging on a cheap off-peak tariff and powering your home during expensive peak hours. Paired with solar, it stores what you generate for use after dark.
Is it safe?
Modern home batteries are safe when installed correctly — properly protected, isolated, ventilated and certified by a qualified electrician. Your consumer unit may need attention to accommodate it.
Common questions
No. A battery can charge on a cheap off-peak electricity tariff and power your home during peak hours. Paired with solar, it also stores the energy you generate.
It depends on your tariff and usage, but many households save by charging cheaply and avoiding peak-rate electricity — and gain some backup during outages. We’ll advise on your situation.
