Cosy Octopus is a 3 rate tariff with double dip Cosy Hours every day: six hours of super cheap electric to warm your home.
You need a heat pump to be eligible for Cosy Octopus, but it doesn’t need to have been installed by us. If you're in the process of getting one installed, you can still switch to Cosy.

To switch to Cosy Octopus you'll need to:
If you're not with us yet, sign up below and you'll join us on one of our standard tariffs initially while we connect all the dots behind the scenes.
We can connect to second generation (SMETS2) meters, and some types of first generation (SMETS1) smart meters.
It generally takes us around 14 days to connect to a smart meter so we can read it remotely – whether it's one we've just installed, or one we're taking over after you switch to us. Read more on this.
Once we're connected and getting half–hourly readings from your smart meter, we'll send you an email asking you to accept the Terms & Conditions of Cosy Octopus to complete your switch. Have a read of our smart tariff Terms & Conditions now..
Your tariff will change automatically to Cosy Octopus. You should see the change straight away on your online account.

You'll need a SMETS2 smart meter, or some types of first generation (SMETS1) smart meters, that we can receive half-hourly consumption data from.
Start your switch below to register your interest for a smart meter. The smart meter installation comes at no extra cost.
Once you've registered your interest, our team will be in contact when we have an appointment in your area.
Cosy Octopus is a beta product. Some things may not work the first time, and installations and processes may take longer than we'd like. Third party tech like In-home Displays won't always work, and on occasion data issues with smart meters can take significant time to fix or prevent things from working at all.
To be eligible for Cosy, you should have a heat pump (air, or ground source) at a property we supply. We may ask you to provide the MCS certificate for your heat pump installation to confirm this.
If you're cool with this, and you'd still like to work with us to make world-changing energy tariffs a reality, check this box so we know you're on board. You will always be able to switch to one of our fairly priced standard tariffs at any time.

No problem. We'll get you up and running, and install a smart meter if you need one at no extra charge.
Cosy Octopus is a cutting edge innovation created by Octopus's unique technology. Unlike products available from other companies, it relies on a smart meter system (which as our Founder Greg explains here, is not always fully reliable). Some customers have experienced delays. However, of the thousands of customers on these smart tariffs, the vast majority are now experiencing smooth service.
The figure is calculated based on a Cosy customer shifting 50% of their heat pump consumption, into the three hour double dip super cheap periods. This saving is compared to the cost of a flat rate Flexible Octopus tariff.
Yes, Cosy is a flexible (aka variable) tariff. This means the price - the unit rates and standing charge - of the tariff can rise and fall with wholesale energy prices.
We'll always give reasonable notice of any changes to the pricing of flexible tariffs. When the price of our flexible tariff changes, the price of your Cosy tariff will also change (as Cosy rates are calculated as a percentage of the flexible rate in your area).
There's no exit fees or tie-ins, so if Cosy Octopus doesn't work for you, you're free to switch tariffs or change suppliers with no penalties at any time.
Remember: your monthly payment isn't fixed. We only recommend changing your Direct Debit if your usage is greatly above - or below - your monthly payments.
No, Cosy Octopus is an electricity only tariff, and takes advantage of the variability of electricity wholesale prices throughout the day.
Yes, all of our innovative tariffs rely on smart meter tech. We also need to be able to link to your smart meter, so we can get at the data. This means you'll need to:
Not with us yet? Join Octopus Energy through our Cosy Octopus sign-up page, and we'll put you on an interim tariff until you've switched and had your smart meter installed / working on our systems.
Industry rules mean we can't replace a meter we don't supply. It's the same story getting the data from your meter; you need to be an Octopus customer. This means we don't know for sure that your account / meter will work with this tariff until we have you on supply with Octopus.
If you don't have a smart meter, we'll contact you to book an installation once your account has switched to us.
Number one and most important: no matter what your In-Home Display (IHD) - the little portable screen you get with smart meters - says, your double dip super cheap periods stay between 04:00 - 07:00 and 13:00 - 16:00 while your peak period stays between 16:00 - 19:00.
Customers on our other smart tariffs sometimes see their in-home display (IHD) showing the off-peak rate kicking in at 01:30am, or their peak rate starting at 17.00pm. This is because IHDs aren't very good at accounting for daylight saving times.
You should trust what we put on your bills. The IHD isn't really determining anything on your meter or tariff, rather just showing some information that might not be correct. Ultimately, our system is set up to account for changes due to daylight savings, so please don't worry: your bills and charges will be correct!
As an alternative, you can use the Octopus mobile app instead and be assured that you are seeing the correct information at all times.
