With these benefits in mind, let’s break down how to make the switch to Octopus Energy in just a few easy steps.

Step-by-Step Guide to Switching to Octopus Energy

Switching to Octopus Energy is designed to be seamless, taking as little as 2-3 working days thanks to the Faster More Reliable Switching (FMRS) initiative. Here’s how to do it:

Step 1: Get a Quote

Start by visiting the Octopus Energy website and entering your postcode. This generates a personalized quote based on your current energy usage. You’ll answer a few quick questions about your household and consumption habits—most are multiple-choice, so it takes less than 5 minutes.

Pro Tip: If you have a recent energy bill, keep it handy to provide accurate usage details for a more precise quote.

Step 2: Choose Your Tariff

Octopus Energy offers a range of tariffs to suit different needs:

  • Fixed Tariffs: Lock in your rates for stability, like the 12-Month Fixed Tariff, which can be up to 15% below the price cap.
  • Variable Tariffs: Flexible options like Octopus Tracker, where rates adjust daily based on wholesale prices, ideal for those who can shift usage to off-peak times.
  • Smart Tariffs: Tariffs like Octopus Go (for EV owners) or Octopus Flux (for solar panel owners) offer cheaper rates during specific hours.

Compare the options and select the one that aligns with your lifestyle and budget. If you’re unsure, Octopus’s website has a handy guide to help you choose.

Step 3: Sign Up Online

Once you’ve picked a tariff, complete the sign-up process online. You’ll need to provide:

  • Your name and address
  • Payment details (Direct Debit is recommended for discounts)
  • Current supplier details (Octopus handles the switch, so you don’t need to contact them)

The entire process takes about 5 minutes, and you can use a referral link to share £50 credit with an existing Octopus customer.

Step 4: Submit Meter Readings

After signing up, Octopus will email you around five days before your switch date to request a meter reading. This ensures your old supplier’s final bill and your first Octopus bill are accurate. If you have a smart meter, this step may be automatic.

Note: You have a 10-day window (5 days before to 5 days after the switch) to submit readings. If you miss it, Octopus will estimate usage with your old supplier.

Step 5: Relax—Octopus Handles the Rest

Octopus will:

  • Notify your current supplier of the switch
  • Arrange the transfer, ensuring no interruption to your energy supply
  • Send you a welcome pack with tariff details and terms

The switch typically completes within 2-17 days, depending on your circumstances, with most customers transitioned in just 3 working days. You’ll receive regular updates via email to keep you informed.

What Happens After You Switch?

Once you’re with Octopus Energy, you’ll enjoy a range of benefits and tools to manage your energy:

  1. User-Friendly App

The Octopus Energy app lets you track usage, submit meter readings, view bills, and adjust Direct Debits. While some reviews note the app could use more advanced features, it’s intuitive for most users.

  1. Smart Meter Installation

Octopus offers free smart meter installations (subject to availability). These devices provide real-time usage data, helping you optimize consumption and save money. If you have an electric vehicle or solar panels, smart meters unlock access to specialized tariffs like Octopus Go or Octopus Flux.

  1. Transparent Billing

Octopus is known for clear, easy-to-read statements. Your first Direct Debit is taken on the switch date, and monthly payments are reviewed to match your usage, preventing unexpected debt or credit buildup.

  1. Ongoing Savings

Customers on tariffs like Agile Octopus have reported savings by using energy during low-demand periods—sometimes even getting paid to use electricity when prices dip below zero!

Common Questions About Switching to Octopus Energy
