So Energy ombudsman & regulator routes

Which ombudsman handles So Energy complaints?

Energy Ombudsman. Once So Energy’s own complaints process is exhausted (after 8 weeks or a deadlock letter), you can take your complaint there for free. Go to the ombudsman. Read our guide to the Energy Ombudsman.

Can you complain to Ofgem about So Energy?

Not for individual disputes: Ofgem sets the rules for the sector but does not resolve personal complaints or award compensation. Complain to So Energy directly first and keep written records, then escalate to the Energy Ombudsman if it stays unresolved after 8 weeks or you receive a deadlock or final-response letter. You can still report So Energy to Ofgem to flag systemic problems, but that will not get your own money back.

We haven't found a complaints email address that So Energy publishes itself, so start from the complaints route on So Energy's own site: https://www.so.energy/help/unhappy. Put "Formal complaint" at the top, with your account or order number, what went wrong, and the outcome you want. Keep a copy of what you send, or a note of the call with the date, so you have a paper trail. If So Energy hasn't sorted it within 8 weeks, you can escalate free to the Energy Ombudsman.
