Commercial battery storage
Battery storage for your business, sized from your actual load.
Storage earns its keep in a business by shifting cheap or self-generated power into your expensive hours — soaking up midday solar, trimming peak-rate demand, and keeping essentials running through an outage. We start from your site's half-hourly data and give you a fixed, itemised price and an honest payback, before you commit to anything.

What storage does for a business
Move power from when it's cheap to when it's expensive
A battery doesn't make energy — it moves it in time. For a business that usually means four things: catching your midday solar surplus instead of exporting it cheaply, charging on a low overnight rate to cover the morning, cutting the expensive late-afternoon peak when demand and unit rates are highest, and keeping essential circuits alive if the grid drops.
Which of those actually pays depends entirely on your load shape and your tariff — so that's where we start, not with a headline kWh figure.
The jobs a battery can do
Sized to the job that actually pays on your site
Some sites want maximum solar self-use; others want to shave a punishing afternoon peak; others just want the lights and tills to stay on. A battery can do more than one — but the sums decide which is worth paying for.
Store your own solar
Catch the midday surplus your building can't use in the moment and spend it in the evening instead of exporting it for pennies.
Cut the expensive peak
Discharge through the costly late-afternoon window so you buy less power exactly when unit rates and demand charges bite hardest.
Keep essentials running
Backup for the circuits you can't afford to lose — tills, servers, cold storage, security — so an outage doesn't stop the business.
Why sizing matters
The right battery is the one that matches your load
Two numbers matter, not one: how much energy it holds (kWh) and how fast it can deliver it (kW). A battery that's big but slow won't shave a sharp peak; one that's fast but small empties before the peak is over. The right pairing comes from your building's half-hourly shape, not a round number off a brochure.
We read your load, model how a battery would actually behave across a real year, and show you the working — including what it saves, what it costs, and how long it takes to pay back.
If someone quotes you a commercial battery without first looking at your half-hourly load, they're guessing. Capacity only means something once it's matched to how your building actually runs.
The honest bit
Storage only works if the numbers do
For a business with a lot of solar, a spiky afternoon peak, or a tariff that rewards shifting, a battery can be a genuinely strong investment. For a flat, all-day load on a simple tariff, the sums can be thinner — and we'll tell you that rather than sell you a box that never pays for itself.
The assessment is where we find out, and the answer is genuinely allowed to be "not worth it for your site" — or "add solar first".
How we do it
Done properly, and itemised in full
You see exactly what you're paying for — the battery, the inverter, the switchgear, the DNO paperwork, the lot — no vague "system price" hiding the detail.
- A free analysis of your real half-hourly data before anything is quoted
- A site survey and design around your building and switchboard, not a template
- Battery capacity and power specified to your load and tariff
- A fixed, itemised quote that doesn't move once issued
- The DNO application (G99 where required) handled for you
- Monitoring and an annual review so it keeps performing

Why we start with your half-hourly data, not your annual bill
Your annual kWh hides the one thing that decides what system you actually need: the shape of how you use power.
