about London

The London region — DNO C, served by UK Power Networks — covers a substantial slice of Great Britain's grid. The live carbon-intensity forecast above is published every half-hour by the National Energy System Operator and applies to every postcode within the region.

If you're on Octopus Agile, your half-hourly price tracks the same wholesale market driving these numbers. For everyone else on a fixed-rate tariff, the answer is the honest "is now a good time to use power" signal — your bill won't change, but the grid is greener when wind and solar are doing the work.
