EDF FreePhase Tariff | Prices Today, Tomorrow & History

EDF FreePhase Tariff

FreePhase is EDF Energy’s three-band time-of-use electricity tariff. Instead of one fixed rate, prices change depending on whether you are in the red, amber or green period each day.

The Dynamic version updates these band prices daily using the same wholesale market data that feeds half-hourly tariffs like Octopus Agile. The Static version of FreePhase keeps the band prices fixed for a year.

When wholesale prices drop below zero, FreePhase can offer free electricity periods. Standing charges still apply, but unit rates fall to zero for the duration of the event.

You can read EDF’s own FreePhase page for their official detail and sign-up info.

This Energy Stats UK page shows today’s and tomorrow’s FreePhase prices and includes a full history of daily band rates so you can see how each band has behaved over time.

Prices Today, Tomorrow and Price History

FreePhase works around four colour coded, fixed time windows that repeat every day:

• 11 pm to 6 am (Green)

• 7pm to 11 pm (Amber)

• 4 pm to 7pm (Red)

• 6 am to 4pm (Amber)

There are two versions of EDF FreePhase.

FreePhase Dynamic

FreePhase Dynamic takes the half-hourly wholesale market data that underpins tariffs like Octopus Agile and averages it into three price bands.

Instead of 48 different prices a day like Agile, you get three simple ones.

FreePhase Static

FreePhase Static locks your rates for 12 months: no surprises, just simple, predictable pricing.

Both versions include a unit rate cap  of 75p per kWh and both can benefit from free electricity periods when wholesale prices go negative. Static customers get those free periods applied as a credit on their bill.

How EDF FreePhase works

Key points

• Three fixed price bands each day (across 4 fixed time periods)

• The Dynamic version uses daily wholesale-based prices

• Static variant keeps the same prices for 12 months

• Free periods appear when wholesale prices go negative

• A working smart meter is required for half-hourly reads

• Price Cap at 75p per kWh

• No Leaving fee

• Day in advance SMS or WhatsApp notification ahead of free electricity

Who FreePhase is suited to

• Homes with EVs that can charge overnight

• Heat pump households that can pre-heat outside the red window

• Solar and battery setups that can take advantage of green periods

• Anyone comfortable planning around banded pricing rather than half-hourly pricing

• Automation or basic scheduling helps you get the most out of it

• Works best if you can avoid the red period from 4 pm to 7 pm

See the EDF eligibility and features page for more information.

Free electricity periods on EDF FreePhase

When wholesale prices go negative, EDF can declare a free electricity period. Dynamic customers see a zero price during the window. Static customers get a credit afterwards.

Note: daily standing charges still apply and will be charged

EDF FreePhase compared to Octopus Agile

Both these smart time of use tariffs are based on the day ahead auction price of electricity which we discussed at length in the Wholesale Energy Pricing article.

Whilst Octopus Agile uses the same 48 x 30 minute structure as the wholesale auction, FreePhase makes the process simpler by creating 4 time bands each day and assigning a single price to those bands.

I’m assuming this simpler structure makes for an easier introduction to time of use tariffs and helps homeowners get their head around when it’s best to use electricity and when not.

Let’s look at a direct comparison of the two tariffs from this snapshot at the beginning of November 2025 in the London region.

FreePhase Versus Agile

As you can see, it just looks like FreePhase just averages out the price of the underlying 30 minute slots to create a single price longer time slot.

Although it appears that EDF aren’t adding the 4pm to 7pm “multiplier” that Octopus do, as explained in their article; Agile Pricing Explained.

One feature in Agile’s favour is that when prices go negative you do get paid by Octopus for using electricity.  Whereas on FreePhase the price is capped at 0p, so free.

I can’t show any free electricity on a graph as I only have FreePhase data since 29th October 2025 and there hasn’t been a negative wholesale slot to this point.  When one comes around I will add some evidence to that.

So on the face of it, it looks like you win some, you lose some across both tariffs.
