Common questions
Contacting First Utility — frequently asked questions
No — First Utility has ceased trading and its customer-service lines have been disconnected. Contact Shell Energy — your new supplier under Ofgem's Supplier of Last Resort scheme — for any account question.
Final First Utility 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.
