British Gas ombudsman & regulator routes
Which ombudsman handles British Gas complaints?
Energy Ombudsman. Once British Gas’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 British Gas?
Not for individual disputes: Ofgem sets the rules for the sector but does not resolve personal complaints or award compensation. Complain to British Gas 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 British Gas to Ofgem to flag systemic problems, but that will not get your own money back.

Tips for British Gas complaints
- Ofgem will not take your case. It says so on its own complaints page: “We do not have a direct role in investigating or resolving customer complaints.” Reporting British Gas there flags a pattern for the regulator, it does not get your money back.
- The Energy Ombudsman is the one that decides, and it is free. British Gas prints the details itself: 0330 440 1624, enquiry@energyombudsman.org, or Energy Ombudsman, P.O. Box 966, Warrington WA4 9DF.
- British Gas publishes no complaints email. Its “We’re listening” leaflet names four routes only: live chat, 0330 808 3880, the online form at britishgas.co.uk/complaints, and post to Customer Care Team, PO Box 226, Rotherham S98 1PB. Any customercomplaints@britishgas.co.uk address on a directory site is invented.
- Eight weeks is the wait, or sooner if a deadlock letter arrives. The Energy Ombudsman then gives you 12 months from receiving that letter to escalate, so a final response you disagree with is a clock starting, not a full stop.
- HomeCare is not energy. British Gas’s home services leaflet sends boiler, plumbing and electrical cover complaints to the Financial Ombudsman Service instead, within six months of its final decision. Send one of those to the Energy Ombudsman and it will be turned away.
- Switched by mistake, or a switch that took more than 5 working days? Ofgem’s guaranteed standards mean you are owed £40 automatically, paid within 10 working days, and a further £40 if British Gas misses that deadline.
- Smart meter waits carry a payment too. Since February 2026 you get £40 if you wait more than 6 weeks for an installation appointment, if the appointment fails through the supplier’s fault, or if you report a fault and get no resolution plan within 5 working days.
