Be pinged the moment tomorrow's Octopus Agile rates drop below 0p/kWh or 10p/kWh — usually within minutes of the 4:00 PM publication.

What time do Octopus Agile prices come out?

Tomorrow's Octopus Agile prices are published every day between 4:00 PM and 4:30 PM UK time. Earlier in the afternoon, the GB day-ahead wholesale electricity auction sets a price for each half-hour of the following day. Octopus converts those wholesale prices into Agile unit rates — applying the regional multiplier, the 4–7pm peak uplift and the 100p/kWh price cap — and pushes all 48 slots to its public API.

Before 4:00 PM, the card above counts down to the release. Once the data lands it switches to tomorrow's lowest, average and highest rates, and the chart shows every half-hour so you can plan EV charging, battery top-ups and laundry for the cheapest times.

How to use tomorrow's rates

  • Set your EV or home battery to charge in tomorrow's cheapest contiguous window (use the calculator).
  • Check for plunge slots below 0p/kWh — you are paid for every kWh you use.
  • Avoid the 4:00 PM – 7:00 PM peak for big loads such as ovens, tumble dryers and immersion heaters.

Tomorrow's Octopus Agile rates FAQ

What time do Octopus Agile rates for tomorrow get published?

Every afternoon between 4:00 PM and 4:30 PM UK time. Octopus converts the results of the day-ahead wholesale electricity auction (which clears around 3:00 PM UK time) into tomorrow's 48 half-hourly Agile prices. AgileWatch UK shows a live countdown to 4:00 PM and switches to tomorrow's rates automatically as soon as they appear.

Is there an Octopus Agile forecast before 4pm?

Octopus only publishes confirmed prices after the day-ahead auction, between 4:00 PM and 4:30 PM UK time. Before then any 'forecast' is a model estimate based on wind, solar and demand predictions. AgileWatch UK only shows confirmed prices from the Octopus API, and counts down to the release.

Why are tomorrow's Agile rates late?

Occasionally the auction results or Octopus’ publication run a little late. The dashboard re-checks every minute after 4:00 PM until all 48 half-hourly slots for tomorrow are available.

How do I find my Octopus Agile DNO region letter?

Type your postcode into the search box at the top of the dashboard. We look up your Grid Supply Point group from the Octopus Energy API (for example _C for London) and save your region on this device. The letter is also the last character of your tariff code on your bill, e.g. E-1R-AGILE-24-10-01-C. There are 14 regions, A to P — the letters I and O are not used.

Why do Octopus Agile prices spike between 4:00 PM and 7:00 PM?

The early evening is when national demand peaks: people get home, cook and switch on heating while solar output falls away. Wholesale prices rise, network costs are highest and Agile adds a fixed peak uplift to every half-hour from 4:00 PM to 7:00 PM. Moving flexible loads such as EV charging, dishwashers and immersion heaters out of this window is the single biggest way to save on Agile.

What is Octopus Plunge Pricing and how do I get paid to use electricity?

Plunge pricing happens when strong wind or solar generation meets low demand and wholesale prices go negative. On Agile, the unit rate for those half-hours drops to 0p or below, so you are credited for every kWh you use. Charging an EV or home battery, heating your hot water tank or running the washing machine during a plunge slot earns you money. AgileWatch shows an electric-blue alert whenever a slot today or tomorrow is at or below 0p/kWh.

Does Octopus Agile have exit fees or a fixed contract?

No. Octopus Agile is a variable tariff with no exit fees and no fixed term, so you can switch to another tariff (such as Flexible Octopus or Octopus Tracker) if wholesale prices rise in winter and switch back later.
