Home battery storage is the fastest-growing part of the UK renewables market. Our guides cover how to choose the right battery, whether Tesla Powerwall or GivEnergy is right for you, what ROI to expect, and how to use smart tariffs like Octopus Go to charge cheaply overnight — even without solar panels.
An honest comparison of the two most popular home battery systems in the UK — Tesla Powerwall 3 and GivEnergy — covering price, performance, features, and which one suits different households.
A common issue with solar + battery + EV charger setups: your expensive battery empties into your car instead of powering your home. Here's how to fix it.
A detailed return-on-investment analysis for home battery storage in 2026 — covering standalone batteries, solar-paired systems, tariff arbitrage, and real payback period calculations.
Choosing the right battery size is the most important decision in a battery storage purchase — too small and it fills up by midday; too large and you are paying for capacity you will never use. This guide explains exactly how to size a home battery in 2026.
Winter is the acid test for home battery storage. Shorter days mean less solar generation, colder temperatures affect battery chemistry, and energy demand peaks. Here is what to realistically expect from your battery in the UK winter months.
All batteries degrade over time — but by how much, and how quickly? This guide explains battery degradation, what warranty guarantees to look for, and how long popular home battery systems realistically last in UK conditions.
The households getting the most from solar and battery storage are those who layer multiple income and saving streams — SEG export payments, cheap overnight charging on Agile or Flux, and timed discharging. This guide explains how to do it.
One of the most common questions about battery storage is whether it provides backup power during a blackout. The answer depends on which system you install and how it's configured. This guide explains exactly what happens when the grid fails — and how to ensure your home stays powered.
Choosing the right energy tariff can add meaningful annual savings for battery storage owners on top of self-consumption benefits. This guide compares every major time-of-use tariff in the UK for 2026 — with real numbers for Yorkshire battery owners.
Every firm in the search results claims to be certified. What Tesla Certified Installer status actually involves, how to check any company on Tesla's own finder in two minutes, and why it decides your 10-year warranty.
Battery storage without solar panels is not just possible, it is increasingly sensible. The September 2026 tariff arithmetic, G99 sign-off rules, the 0% VAT position and when battery-only genuinely stacks up.
Cold weather does not mainly reduce how much a home battery holds — it reduces how fast the battery will accept a charge, and several popular systems stop charging altogether below 0°C. This guide works through what Tesla, GivEnergy, Fox ESS, Enphase and Huawei actually publish, why charging suffers and discharging does not, and what the Met Office figures for the Pennine fringe mean for siting a battery around Huddersfield.
