Octopus Tracker

Britain's most transparent energy tariff

Your prices change every day based on the wholesale price of energy.

Get a transparent look at the true cost of energy – and when the market price drops, so do your bills. Choose Tracker for your electricity, gas, or both.

Track the real cost of energy

We update Tracker prices every day based on an independently published wholesale market price, calculated using our transparent formula. In warmer months, prices tend to be lower, then typically increase – likely double – in colder months.

Enjoy cheaper prices when wholesale prices fall

Unlike standard tariffs that lag months behind the market, Tracker gives you immediate savings when wholesale prices drop.

Price Cap Protect keeps you safe from surge prices

Tracker features Price Cap Protect, which caps the maximum daily price at 100p / kWh for electricity and 30p / kWh for gas. That's a lot higher than Ofgem's energy price cap, so if you can't afford prices to go that high during peaks, you're probably better off sticking with a protected tariff such as Flexible Octopus.

If you're not with us yet, switch to our standard tariff, Flexible Octopus, then return to this page to sign up to Octopus Tracker.

Have a smart meter we can connect to

If you're a customer of ours already, check what type of meter you have on your online account under 'meters'.

We can connect to second generation (SMETS2) meters, and some types of first generation (SMETS1) smart meters.

If you're not a customer of ours yet, contact your current supplier to find out what meters you have. Don't forget – you need either a second generation SMETS2, or a SMETS1 made by Secure™, to be able to join a smart tariff. What if my meter is a SMETS1 that's been remotely upgraded by my supplier?

If your meter has a Secure logo on the front, we should be able to connect to it – this is a Secure™ SMETS1 meter.

Hang tight while we connect to your smart meter

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.

Accept our Terms & Conditions via email

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 Octopus Tracker to complete your switch. Have a read of our smart tariff Terms & Conditions now.

You're all good

Your tariff will change automatically to Octopus Tracker. You should see the change straight away on your online account.
