1. Household customers – 0808 164 1088

Octopus’ main customer-service line handles tariff questions, bills, meter readings, switching supplier and moving home. If you ring outside office hours, you can leave a voicemail; the team aims to call back the next working day.

Peak times to avoid
Industry monitoring shows queues are longest just after Ofgem price-cap announcements and on Monday mornings. Mid-afternoon mid-week is typically the quickest time to get through.

2. Business customers – 0330 808 1080

This line routes straight to a business-only team. Have your company registration number or a recent invoice handy so they can pull up the correct account without delay.

3. Specialist product line – 0808 196 6842

If you’re enquiring about an Octopus air-source heat pump, solar-plus-battery package or EV charger installation, skip the main switchboard and call the dedicated smart-tech team. Using the right line speeds up quote generation and engineer scheduling.

6. Tips for a faster resolution

1. Gather the essentials: account number, postcode, latest meter reading and photos of any error codes.
2. Use the right queue option: the menu lets you press “1” for emergencies, “2” for account questions, etc. Choosing correctly avoids transfers.
3. Call from your registered phone: their system recognises your number, skipping several security questions.
4. Email for non-urgent issues: the inbox is staffed throughout the week, freeing the phone lines for urgent calls.
