EDF Energy’s FreePhase is a time-limited tariff feature that sits alongside its wider smart tariff range, competing with the “free hours” or off-peak style offers you’ll see from other major suppliers. The hook is simple: electricity is free during a set window (here, 8am–4pm tomorrow), so the value comes down to how much of your usage you can shift into those hours without changing your lifestyle too much.

Who will actually benefit from free electricity 8am–4pm?

This suits homes that can move flexible loads into the daytime — think running the washing machine, tumble dryer, dishwasher, batch cooking, or charging devices while you’re in. If you’re out all day and your main usage is mornings/evenings, the headline “free” period may not translate into much saving.

  • Best for: home workers, families at home in the day, households with high daytime appliance use
  • Worth checking: what rates apply outside 8am–4pm, and any eligibility requirements (often smart meter/tariff specific)
