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.
Real savings from real homes
Hundreds of UK households are already using Bloom to make sense of their energy.
"I finally understand my electricity bill."
