Without the hype
Calculators
Interactive calculators: what solar panels and a battery would save on your own Octopus data, and what different heating systems cost to run.
Solar and battery savings
Takes your real half-hourly electricity use from your Octopus Energy account, or a demo household’s, and works out what solar panels, a plug-in balcony kit or a home battery would have saved you on your actual tariff.
Heating costs by SCOP
Compares the running cost, payback and CO2 of heating systems, from an old oil boiler to a well-installed heat pump, at today’s energy prices or your own. It shows what a heat pump saves at each SCOP against what you have now, and can work out your yearly heat use from your home’s measured heat loss.
