Octopus Energy ombudsman & regulator routes
Can you complain to Ofgem about Octopus Energy?
Ofgem does not usually resolve individual billing disputes directly. Start with Octopus, keep written evidence, then escalate to the Energy Ombudsman if unresolved after eight weeks or a deadlock letter.
Which ombudsman handles Octopus Energy complaints?
The Energy Ombudsman. Use it once the supplier’s own complaint process is exhausted, after eight weeks or a deadlock letter. It is free, and its decision binds Octopus if you accept it.
Laws that protect you
Consumer Rights Act 2015
Energy services must be performed with reasonable care and skill. You’re entitled to a remedy if service falls below acceptable standards.
Ofgem Standards of Conduct
Suppliers must treat customers fairly, provide accurate bills, and handle complaints properly. Breaches can be reported to Ofgem.
Energy Ombudsman Scheme
Free dispute resolution after 8 weeks of unresolved complaints. Can award up to £10,000 in compensation.
Ofgem Guaranteed Standards
Automatic compensation for missed appointments, delayed supply restoration, and billing errors. £30-£150 per breach.
Back-Billing Rules
Energy suppliers cannot charge for unbilled energy more than 12 months old if they’re at fault for the delay.
Tips for Octopus Energy complaints
- Submit meter readings regularly via the Octopus app or website to ensure accurate billing
- If your smart meter isn’t working, request a manual meter reading and log the fault
- Octopus must respond to complaints within 8 weeks - mark this deadline
- After 8 weeks without resolution, escalate free to the Energy Ombudsman (ombudsman-services.org)
- Keep screenshots of app errors, incorrect readings, and all email correspondence
- Check if you’re on the best tariff - Octopus has several including Agile and Tracker
- Request a 'deadlock letter' if Octopus can’t resolve your complaint - this lets you go to the Ombudsman early
- For billing errors over 12 months old, cite Ofgem’s back-billing rules
