Switching to Octopus is straightforward — the sign-up takes about 5 minutes online, there’s no supply interruption, and you don’t need to cancel anything. If you use my referral link, we both get £50 credit after your first Direct Debit.

Octopus will ask for your postcode, current supplier, and an estimate of your usage (or your meter serial number if you have it handy). You can use a rough annual usage estimate if you don’t have your bills to hand — it doesn’t need to be exact.
Octopus will show you available tariffs. Most customers start on Flexible Octopus — a fair variable tariff that tracks the Ofgem price cap. If you have a heat pump or EV, you can also apply for Cosy Octopus or Intelligent Octopus Go after joining (a smart meter is required for those).
Octopus will ask for your bank details to set up a monthly Direct Debit. This is standard for all energy suppliers. Your first Direct Debit is the trigger for the £50 referral credit to be applied.
Once you’ve signed up, Octopus handles the entire switch. They notify your current supplier and manage the changeover. You do not need to cancel your old supplier yourself — Octopus does it for you. The switch typically completes within 3 weeks.
Approximately 2–3 weeks after your first Direct Debit is taken, £50 credit is applied to your Octopus account automatically. You’ll get an email notification. The same credit goes to me as the referrer.
Will my energy be cut off? No. The switch is entirely administrative. Your electricity and gas continue without interruption throughout the process. You won’t notice any difference to your supply.
Do I need to call my current supplier? No. Octopus handles all communication with your existing supplier. You just sign up online and Octopus does the rest — no cancellation calls needed.
What if I’m in a fixed contract? Check whether your current tariff has exit fees — these vary by supplier and tariff. Octopus has no exit fees on its variable tariffs, but your old supplier may charge to leave a fixed deal early. It’s worth checking this before switching, though for many people the savings still outweigh the exit fee.
On your switch date, you should take a meter reading and submit it to both your old supplier and Octopus. This ensures you’re billed accurately up to the point of changeover. Octopus will prompt you to submit a reading around switch time — they send a reminder so you won’t miss it.
If you have a smart meter, readings are taken automatically and you don’t need to do anything manually.
No — you do not need a smart meter to switch to Octopus Energy or to claim the £50 referral credit. You can join on the standard Flexible Octopus tariff with a traditional meter.
If you’d like to access smart tariffs like Intelligent Octopus Go (for EVs) or Cosy Octopus (for heat pumps), a SMETS2 smart meter is required. Octopus can arrange a free installation — you can request this after joining.
The whole process takes about 5 minutes. Click the button below — the referral is attached automatically and you’ll both get £50 credit once your first Direct Debit clears. Remember: click the link, don’t type the URL.

No. Your supply continues uninterrupted throughout the switch. The changeover is entirely administrative — Octopus and your old supplier manage it in the background. You will not notice any disruption to your electricity or gas.
The online sign-up takes around 5 minutes. The actual transfer of supply typically takes around 3 weeks from sign-up, during which Octopus handles everything. You’ll receive emails keeping you updated on progress.
No — you don’t need to contact your old supplier at all. Octopus Energy notifies them and manages the entire changeover. Just sign up with Octopus and they handle the rest.
The £50 credit is applied to your Octopus account approximately 2–3 weeks after your first Direct Debit payment is taken. You’ll get an email when it lands. Remember: you must switch by clicking the referral link — typing the URL directly won’t trigger the credit.
No — a smart meter is not required to switch or to claim the referral credit. You can join Octopus on a standard tariff without one. If you later want to access a smart tariff like Intelligent Octopus Go or Cosy Octopus, Octopus will install a smart meter for free.
