Home battery storage in Essex.
Store the power your panels generate during the day and use it in the evening, instead of exporting it back to the grid at a lower rate. Works alongside an existing solar system or as part of a new one. Solar and battery installations are also currently zero-rated for VAT, a relief that runs until 31 March 2027.
When does a battery actually pay off?
That comes down to when your household actually draws power. Evening-heavy households get the most from a battery, banking what the panels made earlier instead of exporting it for less than you’d pay to buy it back. We work this out properly at quote stage rather than assuming it’s the right fit for everyone.
Retrofitting a battery to an existing array is usually straightforward, no need to touch the panels. We check your inverter and setup first to confirm everything’s compatible.
Sizing it without overspending.
UK home batteries span roughly 5 kWh to 50+ kWh, though most households never need the top end of that range. A typical 3–4 bedroom home gets through 3,500–5,000 kWh a year, and evening/overnight draw, once the panels have stopped for the day, usually sits around 3–7 kWh. That puts most Essex homes in an 8–16 kWh usable-capacity bracket: enough for a normal evening, without paying for capacity you’ll rarely touch.
The average only gets you so far, though. A household running appliances every evening needs more capacity than one that’s mostly out. We size against your actual usage, not a generic number.
There’s more to a battery than storing solar.
Banking daytime generation for later is the main job, but most modern batteries do more than that. Many can top up from the grid on a cheap overnight rate and release it during peak pricing, or push stored charge back to the grid under the Smart Export Guarantee when the export rate beats the cost of holding onto it. Whether any of that’s worth setting up depends on your tariff, which we go through at quote stage.
Can I add a battery without solar panels?
Yes, that works as a standalone setup. Charging purely on a cheap overnight rate and drawing it down during peak hours is genuine, though pairing it with solar tends to shorten the payback.
How long do home batteries last?
A 10-year warranty, or a set cycle count, whichever comes first, is standard on most lithium home batteries sold in the UK, and in practice they usually keep going well past that. Exact terms depend on the product and get confirmed with your quote.
Where does the battery get installed?
Most commonly a garage, utility room, or an external wall near your consumer unit and inverter. The survey confirms the right spot for your particular property.
