Built around your real usage
Recommendations use your actual half-hourly data — never a generic estimate.
Why starting small works better
Most homes don't need the biggest battery. They need the right battery.
£3,800 upfront · 8+ year payback
Sits half-empty most days. You're paying for capacity you never use.
£1,799 upfront · ~3 year payback
Works hard 95% of days. Every kWh of capacity earns its keep.
We recommend smaller setups on purpose — and you can always expand later.
Built around your real smart-meter data
Bloom works with Intelligent Octopus Go and other Octopus tariffs. We use your real half-hour usage to recommend a setup that actually fits your home — never a generic estimate.
