EDF's new gadget for dynamic tariffs

EDF is giving customers on its FreePhase tariffs a free SeeZero in-home display. The device pulls live smart meter data and shows today's electricity prices, prices for the next day and any zero-price hours when they appear. It also tracks real-time energy use and spending in pounds and kilowatt-hours, plus historical data by hour, day, week or month.

How the tariffs compare with the standard variable rate

FreePhase Dynamic changes unit rates daily with wholesale prices in a three-rate structure. Off-peak (amber) rates average 22% cheaper than the standard variable tariff and night (green) rates are 29% cheaper. FreePhase Static fixes the same three rates for 24 months, with night rates up to 33% cheaper than the standard variable tariff. Both tariffs also give free electricity during periods of excess renewable generation. Customers on the tariffs have already saved more than £140,000 in total, and more than nine in ten pay less than on EDF's standard variable tariff.

What the display adds and who it suits

Joe Souto, EDF Retail Director, said: "With average bills set to rise from 1 January we are always looking at ways to help customers bring their costs down. We are delighted that FreePhase has helped customers save £140,000 by giving them greater control over their energy use. The SeeZero display will make it easier to act on that choice by bringing energy prices, energy use and spending together in one place.

“The display has been developed to help those wanting to take a more active role in managing their energy use and when most efficient to complete everyday tasks such as running washing machines, dishwashers or other flexible appliances.”

The display also includes customer access device functionality for future smart services. It is available to order now for FreePhase customers who have a compatible smart meter. You can compare energy tariffs to see if a time-of-use deal fits your household's routine.
