Step 4: Octopus Handles Everything

Once you've submitted your application, Octopus takes care of the entire switching process:

How Long Does Switching Take?

The switching timeline depends on your current situation:

⚠️ Important: Check if you have exit fees with your current supplier. However, if you're within 49 days of your contract end date, you're protected from exit fees by law. Octopus will flag this during your application if it's an issue.

What Happens on Switch Day?

Your switch happens automatically at midnight on the agreed date. You won't notice anything different:

After Your Switch Completes

Within a few days of switching, you should:

  1. Submit meter readings via the Octopus app or online account
  2. Set up your online account to manage payments and track usage
  3. Download the Octopus app for easy account management
  4. Check your first bill which arrives within 2 weeks
  5. Receive your £50 referral credit within 4-6 weeks of switching (if you used a referral link)

Can I Switch If...

I'm in a Fixed Contract?

Yes, but you may face exit fees unless you're within 49 days of your contract end. Octopus will show any fees during signup so you can decide if it's worth switching immediately or waiting.

I Have a Smart Meter?

Absolutely. Octopus supports all smart meter types. SMETS2 meters work seamlessly, while older SMETS1 meters may temporarily operate in "dumb" mode until Octopus upgrades them.

I Rent My Property?

Yes, as long as you're responsible for the energy bills (not included in rent), you can switch supplier without landlord permission.

I'm Moving House?

You can arrange for Octopus to supply your new property from your move-in date. Just select "moving home" during signup rather than "switching supplier."

Common Questions

Will my energy supply be interrupted?

No. Your supply continues uninterrupted throughout the entire switching process. It's managed electronically between suppliers.

Do I need to tell my old supplier?

No. Octopus handles all communication with your previous supplier. You don't need to contact them.

What if I change my mind?

You have 14 days to cancel your switch for any reason under consumer protection regulations. After that, Octopus has no exit fees, so you can leave with 28 days notice.

When do I get my £50 referral credit?

The £50 credit appears in your account approximately 4-6 weeks after your switch completes. It's automatically applied to reduce your energy bills.

Switching to Octopus Energy takes about 5 minutes online and requires minimal effort from you. The entire process is managed by Octopus, your energy supply continues uninterrupted, and if you use a referral link, you'll receive £50 credit to reduce your bills.

With no exit fees, award-winning customer service, and 100% renewable electricity, there's very little risk in making the switch. Most customers complete the process and wonder why they didn't switch sooner.
