Octopus Energy Contact Number and Support Info (Updated 2026)
Last Updated: July 1, 2026
Octopus Energy contact number: 0808 164 1088 (freephone, Monday to Friday 9am to 5pm). For non-urgent account help, email hello@octopus.energy or use the in-app messaging. For gas emergencies, do not wait for Octopus. Call the National Gas Emergency Service on 0800 111 999 immediately.
Quick tip: most routine tasks like meter readings, tariff changes, and billing questions are faster through the Octopus app or online dashboard than by phone.
When you need to contact Octopus Energy, knowing which route to use saves more time than any phone number alone. The main contact number is 0808 164 1088 for general customer service, but for routine tasks like meter readings, tariff changes, and billing questions, the app or email is often faster. This guide covers every way to reach Octopus, which method to use for different types of problem, and the emergency numbers that are completely separate from Octopus customer service.
Quick Answer: What Is the Octopus Energy Contact Number?
The main Octopus Energy contact number is 0808 164 1088. It is freephone from UK landlines and mobiles. Lines are open Monday to Friday, 9am to 5pm. Outside those hours, email and in-app messaging are the better routes, and emergency gas or power issues should go straight to the national emergency services, not to Octopus.
This page covers every way to reach Octopus Energy, which method to use for different types of problem, and how to save time when you do get in touch.

When to Phone
Phone 0808 164 1088 when the issue is urgent, complicated, or stuck. If you have been going back and forth over email without resolution, a phone call usually cuts through faster. Billing disputes, meter problems that need explaining verbally, and account access issues that lock you out of the app are all phone-worthy.
Have your account number and the registered address ready before you dial. The less time you spend finding your details on the call, the quicker the agent can get to the actual problem.
Octopus does not have weekend phone hours. If your issue arises on a Saturday or Sunday, email or the app are your options until Monday morning.
When Email or the App Works Better
For non-urgent tasks, written support has an advantage: it leaves a trail. You can refer back to what was said, attach screenshots or photos of meters, and avoid repeating yourself to different agents.
Common tasks that work better through email or the app:
– Submitting meter readings with a question attached
– Requesting a tariff change or account update
– Sending documents like a tenancy agreement or final bill
– Asking about your account balance or payment schedule
– Reporting a minor issue that does not need an immediate fix
The Octopus app also lets you do most account management without contacting anyone at all. Meter readings, tariff switches, direct debit adjustments, and payment top-ups are all self-service.
Emergency Contact: Do Not Wait for Octopus
A gas leak or electrical emergency is not a customer service problem. If you smell gas, suspect a leak, or have a power cut with immediate danger:
- Gas emergency: 0800 111 999 (National Gas Emergency Service, 24 hours)
- Power cut: 105 (national power cut helpline, connects to your local network operator)
Contact Octopus after you have spoken to the emergency services, not before. Safety first, customer service second.
What to Have Ready Before You Contact Octopus
Spending two minutes gathering these details before you call or email can save ten minutes on the other end:
- Your Octopus account number (top right of any bill or in the app under Account)
- The full address and postcode registered on the account
- Recent meter readings or a photo of the meter
- A short summary of the issue, including dates and what has already been tried
If it is a billing problem, have the relevant bill open. If it is a meter issue, a photo of the meter with the serial number visible is often more useful than describing it.
Common Questions
What is the Octopus Energy contact number for complaints?
The same number applies: 0808 164 1088. Ask to speak with the complaints team when you get through. Octopus also has a formal complaints procedure on their website. If your complaint is not resolved within eight weeks, you can escalate it to the Energy Ombudsman, which is a free independent service for energy disputes.
Can I contact Octopus Energy on weekends?
Phone support runs Monday to Friday, 9am to 5pm. On weekends, you can email hello@octopus.energy, use the in-app messaging, or try the website live chat if it is available. The social media team on Twitter may also respond on weekends but is not a guaranteed support channel. Emergency gas and power issues have 24-hour helplines that are completely separate from Octopus.
Is there a live chat for Octopus Energy?
Yes. Log into your Octopus online account and look for the chat icon. Live chat is available during business hours and connects you to a support agent through the browser. It is often faster than email for straightforward questions and, like email, it gives you a written record of the conversation.
How do I submit a meter reading to Octopus?
You do not need to contact support for this. Log into your online account or the Octopus app and submit the reading directly. If you have a smart meter, readings are sent automatically and you do not need to do anything. If you are having trouble submitting a reading through the app, email hello@octopus.energy with a photo of the meter and your account details.
What is the best way to contact Octopus about moving home?
Use the moving home section in your Octopus online account or app. It walks you through the process step by step and covers both your old property and the new one. If something goes wrong during the process, call 0808 164 1088 and explain that it is a home move issue. Having the move dates, old and new addresses, and final meter readings ready will speed things up.
Does Octopus Energy have a postal address?
Yes. The registered office is Octopus Energy, UK House, 5th Floor, 164-182 Oxford Street, London, W1D 1NN. For most queries, phone, email, or the app are faster than post. If you need to send a formal letter or physical documents, use that address and include your account number on every page.
I have contacted Octopus Energy a handful of times since switching to them for my home electricity and EV charging. Once for a billing question after my smart meter was installed, once when I moved house, and once to clarify how the Intelligent Go export rates worked alongside solar.
Each time, the response was faster through the app than by phone. The in-app messaging gave me a written answer I could refer back to, and I did not have to sit on hold. My rule of thumb: try the app first for anything that is not urgent. If the app does not fix it within a day, pick up the phone.
One thing worth knowing: Octopus support is generally well-reviewed compared to most energy suppliers, but wait times on the phone can spike during industry-wide events like price cap announcements or supplier failures. If you can wait a day, email during those periods rather than calling.
I’m Steven, founder of MoneyAppReviews. I test money apps, referral programs, and EV tools in real life before I write about them. I drive a 2021 Tesla Model 3 Long Range, use Octopus Intelligent Go for home charging, and regularly track costs, savings, and app performance over time. I focus on practical, evidence-based reviews that help people decide what is actually worth using, not just what pays the highest commission.
