Frequently Asked Questions about Octopus Energy and the Tracker Tariff
How do I sign up to Octopus and access the Tracker?
To gain access to the tracker rates, you must:
- Ask a friend who's already with Octopus Energy for their referral link - you'll both get £50 bill credit (splitting £100 total!)
- Sign up to the Flexible Ofgem Cap Tariff
- Apply to join the Tracker
- Be a little patient (it takes a few days for Octopus to switch you over)
Do I need smart meters to join Octopus Energy?
No. You do not need smart meters to join Octopus and receive the £50 bill credit (when you use a friend's referral link). However, you need smart meters to join the Tracker tariff.
How does the Tracker compare to the government cap?
The Tracker adjusts daily based on wholesale energy prices. When wholesale prices are lower than the Ofgem price cap, Tracker rates may be lower. When wholesale prices rise, Tracker rates may be higher. Past performance is not indicative of future results.
If prices go up, can I switch back to the Ofgem Cap tariff (Flexible)?
Yes. That is why I built this price tracker. Keep an eye on prices, and if they go above the cap then you can switch back to the Flexible tariff. However, if you leave the Tracker, you cannot rejoin it for 9 months.
Is it easy to switch back to a fixed tariff?
Yes. To switch back, you just choose a different tariff on your account page. Alternatively, email or phone Octopus. However, Octopus states switching to another Octopus Energy tariff may take two weeks.
Get £50 Bill Credit to Switch to Octopus Energy
In case you were wondering, I don't work for Octopus Energy. I read about the Tracker tariff on r/beermoneyuk a few years ago and signed up. The Flexible Tariff is Octopus's Ofgem Cap tariff, while the Tracker is a variable tariff that follows wholesale prices.
I use Octopus Energy myself and track these prices to monitor my own energy costs. If you'd like to sign up, ask a friend who's already with Octopus for their referral link - you'll both get £50 bill credit (splitting £100 total!).
