How Bloom works
We turn your real Octopus smart-meter data into a clear, personalised battery recommendation. Here's exactly how.
1
You connect your Octopus account
Read-only access — we can only see your half-hourly usage and tariff. We can't change anything, touch your bill, or access payment details. You can disconnect anytime.
2
We analyse your real usage
We look at when you use electricity, how much you spend in expensive periods vs cheap overnight rates, and how that pattern repeats across days and seasons.
3
We size the right battery for you
Bigger isn't always better. We find the battery setup that pays back quickest for your actual usage — not a generic home.
4
You get a clear recommendation
One main suggestion, plus smaller and larger options so you can see the trade-offs. With honest savings, payback, and trust signals throughout.
