Common questions
Contacting Spark Energy — frequently asked questions
No — Spark Energy has ceased trading and its customer-service lines have been disconnected. Contact OVO Energy — your new supplier under Ofgem's Supplier of Last Resort scheme — for any account question.
Final Spark Energy bills are issued by the company's administrators, not by the SoLR. Contact the administrators directly — their details are usually published in the Companies House filings linked from the Ofgem cessation announcement. If the dispute is not resolved, the Energy Ombudsman remains the binding ADR route even after a supplier has ceased trading.
