Agile Octopus, Cosy Octopus, Octopus Go, and Octopus Go Green 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 and Go Green, 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, If you switch from Agile Octopus, Cosy Octopus, Octopus Go, and Octopus Go Green 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 30 day policy has been introduced.

The 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 100p/kWh). We may change the formula or cap from time to time and will give you reasonable notice if we plan to do this
  2. The variable nature of Agile Octopus means any prediction of future costs will be inaccurate and historical data will not predict future performance.
  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 within 30 days.

The Terms and Conditions are, for Cosy Octopus:

  1. Cosy Octopus is designed for customers who have a heat pump (air, or ground source) installed and operational at the property which we supply. We may ask you to provide your MCS installation certification to confirm this.
  2. If you sign up to our Cosy Octopus tariff but do not meet this eligibility criteria, we can place you on an alternative tariff that we consider is more appropriate for your circumstances. We will let you know if we do this and advise you of the rates and terms that apply to the alternative tariff.
  3. Cosy Octopus is a Variable Rate Tariff, with your daily standing charge, quoted day rate per kWh, two lower price per kWh “boost periods” (from 04:00 - 07:00 and 13:00 - 16:00), and a “peak period” rate per kWh (from 16:00 - 19:00).
  4. By taking Cosy Octopus, you agree to us using half-hourly consumption data collected from your smart meter to bill you.
  5. 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”).
  6. Cosy Octopus is a beta product. This means some things may not work the 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.
  7. Cosy Octopus is compatible with our “Octopus Outgoing Smart Export Guarantee” and “Octopus Outgoing Fixed” export tariffs and no other Octopus export tariffs.

  6. Our Octopus Go Tariff is designed for customers who either own or long term lease a battery electric vehicle or a plug-in hybrid vehicle that they will be charging at home.
  7. If you sign up to our Octopus Go tariff but do not meet this eligibility criteria we can place you on an alternative tariff that we consider is more appropriate for your circumstances. We will let you know if we do this and advise you of the rates and terms that apply to the alternative tariff.

The Terms and Conditions are, for Octopus Go Green:

We’ve recently made a change to how often you can switch between our Agile Octopus and either Octopus Go or other 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.

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.

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.
