The Terms and Conditions of Agile Octopus and Octopus Go

The Agile Octopus and Octopus Go tariffs are uniquely innovative products of our labs, and available now to customers through our beta programme. With them, tens of thousands of Octopus customers get cheap green electricity at off peak times with Go, or when the sun shines and the wind blows with Agile.

However, these are beta products, they use our latest proprietary technology and smart meter infrastructure and are reliant on a number of 3rd party processes that may not always be reliable. 

All customers who would like to use these smart tariffs must have a compatible smart meter (which we can install free of charge) and also agree to accept that it’s dependent on installations and processes which may take longer than we'd like, and that on occasion issues with smart meter data, communications etc. can take significant time to fix or prevent things working at all.  We commit that if our smart tariffs don’t work for you, you will always be able to switch to one of our fairly priced standard tariffs at any time.

Whilst you can always switch from standard tariffs to smart tariffs if you decide it’s not for you, we have recently (October 2020) introduced a limitation the other way. If you switch from Octopus Go or Agile Octopus to another Octopus tariff, you cannot switch back to a smart tariff within 30 days.

Below is a summary of our smart tariff terms and conditions, and a further explanation of why the new 30 day policy has been instigated.


These Terms and Conditions are, for Octopus Go:

  1. Octopus Go is a fixed tariff, with your daily standing charge, quoted day rate per kWh and 5p night rate (for 4 hours starting 00:30) fixed for 12 months.
  2. By taking Octopus Go, you agree to us using half-hourly consumption data collected from your smart meter to bill you.
  3. In the absence of half hourly smart meter data, we will charge you as we would a customer on our Flexible Octopus variable tariff, based on typical consumption patterns (known as “Profile 1”).
  4. Octopus Go is a beta product. This means some things may not work first time or may break and that on occasion data issues with smart meters can take significant time to fix or prevent things working at all. You will always be able to switch to one of our fairly priced standard tariffs at any time.
  5. You can switch away from our Octopus Go tariff to one of our standard tariffs any time without financial penalty, but you can’t move back to one of our smart tariffs (Agile Octopus or Octopus Go) within 30 days.


These Terms and Conditions are, for Agile Octopus:

  1. Prices are calculated based on a formula related to wholesale costs, and usually published between 4-10pm (normally, but not always, nearer 4pm), for the following day, with a different price for every 30 minutes of every day. Prices can rise as well as fall (though they are capped at 35p/kWh). If you prefer the security of fixed prices, you should consider our Fixed or SuperGreen Octopus tariffs.
  2. The variable nature of Agile Octopus means any prediction of future costs will be inaccurate and historical data will not predict future performance. The costs shown above are based on estimated average unit rates for the next 12 months and average consumption profiles, and in no way constitute a guarantee of actual cost.
  3. By using Agile Octopus, you agree to us using half-hourly consumption data collected from your smart meter to bill you.
  4. In the absence of half hourly smart meter data, we will charge you as we would a customer on our Flexible Octopus variable tariff, based on typical consumption patterns (known as “Profile 1”).
  5. Agile Octopus is a beta product. This means some things may not work first time or may break and that on occasion data issues with smart meters can take significant time to fix or prevent things working at all. You will always be able to switch to one of our fairly priced standard tariffs at any time. Agile Octopus is a smart tariff that allows you to unlock the cheaper and greener benefits of using energy according to wholesale costs. Sometimes peaks may be higher, sometimes lower - overall you are likely to benefit.  You can leave Agile Octopus at any time, but you cannot switch back to it within 30 days.
  6. You can switch away from our Agile Octopus tariff to one of our standard tariffs any time without financial penalty, but you can’t move back to one of our smart tariffs (Agile Octopus or Octopus Go) within 30 days.


We’ve recently made a change to how often you can switch between our Agile Octopus and Octopus Go smart tariffs. These tariffs offer customers the ability to unlock cheaper (and greener) electricity prices by using energy at particular times. They work best with that change in behaviour, and are designed for the long term.

For our fixed tariffs, we buy a customer’s energy for the 12 months ahead and price the tariff so that there’s a small margin for us to cover the costs of doing business. Our Flexible (SVT) tariffs follow the market more closely so can go up or down (but we’ll always give fair notice of any changes) and are bought in advance too, but for shorter periods..  

Agile Octopus is designed to do away with all that: with prices based on the day-ahead wholesale market and charged based on what a consumer actually uses each half hour.  Agile Octopus customers are then able to adapt when they use their energy, in particular avoiding peak times, to make significant savings. 

We don’t hedge the consumption of Agile customers - ie. we don’t buy their energy in advance, The whole point is that prices reflect the current wholesale market. But we do hedge fixed tariffs (including Octopus Go). As such, if Agile customers switch to a fixed tariff, we then hedge their expected consumption - we buy it in advance at fixed prices. If customers then switch back to Agile, we’re stuck with having bought it according to standard consumption, but then paying for it according to the prevailing wholesale market every half hour.

So customers moving from Agile to fixed tariffs is ok, moving back the other way is harder for us.

Octopus Go is a great tariff with its off-peak rate of only 5p between 00.30 and 04.30, so it’s not surprising it’s seen as attractive. Octopus Go is hedged according to the expected consumption profile of a Go customer - that is, we buy your energy in advance for every half hour, based on our experience of typical Go customers. So if a Go customer switches back and forth between other tariffs, and changes consumption patterns, our hedging no longer works. So, as with Agile, we need to reduce the speed at which people can switch back and forth between Go and other tariffs.

We’ve retained the ability to leave smart tariffs at any time - if they’re not for you we don’t want you locked into them. We’ve just added the 30 day restriction to prevent the “back and forth” which can undermine the way they’re designed to work. Of course, as ever with Octopus, there’s no exit fees and no lockins.

And we’re delighted to be at the vanguard, to be moving from a world where customers never switched, to one where we have had some customers looking at intraday switching, powered by our APIs which are still a unique feature of Octopus. This is an incredible journey, together, bringing the cleaner, greener, cheaper future of energy into the present.
