See what your home is really doing —
to the planet, and your bill.
Grid.Local pairs live UK regional grid carbon with your energy data — automatically via Octopus Energy and GivEnergy, or by uploading your own figures. See your home's true footprint, what you actually pay, and how a different tariff or battery would change things — all in one place.
Live grid carbon
Real-time gCO₂/kWh for your DNO region, refreshed every 30 minutes. See the live generation mix — wind, solar, gas, nuclear — and when it's the greenest moment to run the dishwasher.
Your home's footprint
Your actual carbon from grid imports, minus what your solar exports save the grid. Day, week, month, year — see the impact of every kWh you use and produce.
What you really pay
Track what you've spent on Octopus Agile, Cosy, Go or Flux — or just enter your monthly totals. Instantly see what the same usage would have cost on a different tariff. No spreadsheets.
