Is Octopus Energy open at weekends?
For normal account questions on Saturday or Sunday, Octopus directs customers to hello@octopus.energy. Seven-day email support does not mean every message receives an instant reply or that routine phone lines operate around the clock.
For a non-urgent question after the phones close, write down what you need and send an email. If you prefer a conversation, plan to call during the next advertised phone session. Emergency supply problems use the separate routes below.
The official contact page links to account tools for meter readings, statements, payments and moving home. These can be useful when your question is a straightforward account task.
Bank holiday and Christmas opening hours
The table above shows the standard weekly timetable. It is not a confirmed timetable for Christmas, Easter or an individual bank holiday. Check Octopus’s official contact page and any current account notices before planning a call around a holiday.
All times in this guide are UK local time, following GMT or British Summer Time as applicable. If you are calling from abroad, check the time difference and your network’s calling charges.
Octopus emergency opening hours and numbers
Choose the service that matches the problem. A local electricity-network outage, a suspected gas leak and an Octopus meter fault need different help.
| Situation | Contact |
|---|---|
| Meter sparking or on fire | Call 999. |
| Smell gas or suspect a gas leak | Call the National Gas Emergency Service: 0800 111 999. |
| Local electricity power cut | Call 105 for your electricity network operator, available 24/7. |
| Urgent Octopus supply or meter problem | Use Octopus’s emergency support below. |
Octopus’s official no-gas-or-electricity guide lists emergency phone support on 0808 164 1088 from 8am–8pm Monday to Friday. Outside those hours, leave a voicemail; Octopus says these are monitored constantly for priority callbacks.
Its emergency inbox, emergency@octopus.energy, is monitored 24/7, including weekends. Put “emergency” in the subject. This is separate from ordinary billing or referral enquiries. See the official emergency guidance for the current arrangements.
If a prepayment meter has run out and you cannot afford to top up, contact Octopus promptly. Its emergency credit guidance explains the available support; borrowed meter credit must be repaid.
Business, heat pump, solar and EV support
Choosing the right team can save you explaining the same enquiry twice. Keep an energy-account question separate from an installation or equipment problem.
- Small business energy: 020 3389 5613 or business@octopus.energy. The business contact listing shows the same weekday phone timetable as home energy.
- Heat pumps, solar and EV chargers: 0808 196 6842, Monday–Thursday 9am–5pm and Friday 9am–4pm. For an installed system, Octopus lists aftercare@octopus.energy. See its installation and aftercare contact guidance for specialist and urgent routes.
- BSL support: the free SignVideo service is available through the official contact page during the published weekday customer-service hours.
For an EV charger enquiry before installation, Octopus also lists charging@octopus.energy in its EV support information. Vehicle leasing and public charging are separate services, so use the contact route for the product you have.
Before you contact Octopus
A short, specific enquiry makes it easier to explain what needs resolving. Have your account reference, supply address and any relevant bill, meter reading or booking reference ready. Share account details directly with Octopus, rather than posting them in public comments.
- Switching query: note your application date, expected start date and the part of the transfer that needs attention. Our guide to switching to Octopus Energy explains the handover steps.
- Missing reward: keep the referral link and first-payment details beside you. Read the £50 referral credit checklist before chasing a payment.
- Tariff query: identify the tariff name and the rates or eligibility you want clarified. Our Octopus Energy tariff guide helps you compare the options.
New customer? Check the £50 referral offer
If you are looking up opening hours because you are considering joining, read our Octopus Energy new customer offer guide before applying. A qualifying household referral gives the new customer £50 energy-account credit and the referrer £50 too. It is a one-off reward, separate from the price of your tariff.
Check the £50 offer on Octopus’s referral page before signing up. Eligibility and the official terms apply; clicking the link alone does not earn credit. Octopus’s referral FAQ says the switch and first successful month’s Direct Debit must be completed before credit can be added.
Compare your quote using annual usage, unit rates and standing charges. Our homepage has the Octopus Energy referral code and joining overview. This independent site’s referrer may receive credit if you qualify.
Opening-hours questions
Is the Octopus Energy phone number free?
The domestic 0808 164 1088 number is free from UK mobiles and landlines. Business customers use a separate 020 number; check your phone plan for its charges.
Can I call Octopus on Sunday about my bill?
For routine Sunday enquiries, use email or plan a weekday call. The emergency routes above are for urgent supply issues, rather than general billing support.
Does “24/7 support” mean a live adviser answers every call?
No. Octopus’s emergency guidance distinguishes its emergency phone hours from the out-of-hours voicemail callback service and monitored inbox. It does not promise round-the-clock live phone support for ordinary enquiries.
What is the best time to call Octopus Energy?
We have not verified live queue data or a reliably quiet time of day. Choose a time within the published schedule when you can explain your enquiry and have your account information ready.
Are Weekend Happy Hours the customer-service hours?
No. Weekend Happy Hours is an electricity reward programme with its own conditions. It does not describe when the customer-service phone line opens.
