Less heat when the house is empty. More when power is cheap.
In a modelled 2024 study, Bloom cut annual grid energy cost by £615 (38.1%) for a full home on Octopus Agile versus heat-pump weather compensation alone — including smart shifting of EV, DHW and battery. Heating-only: £193 (12.0%) versus the same WC baseline.

What Bloom does
Bloom watches occupancy and your tariff. It setbacks when you’re away, preheats before you return, coasts through expensive slots, and runs DHW, EV and battery on cheap power or leftover solar — instead of fixed timers.
Bloom is optional, and off by default.
