How to complain about Bulb Energy (and actually get somewhere)
A common mistake: going to Ofgem. Ofgem regulates the market but doesn’t resolve individual complaints - this is the route that does.
- 1
Complain to Bulb Energy in writing
Include your account number, what went wrong, and the outcome you want. Writing creates the paper trail you'll need later.
- 2
Give them 8 weeks
Suppliers get 8 weeks to resolve a complaint. If they send a deadlock letter sooner, you can skip ahead.
- 3
Escalate to the Energy Ombudsman - free
After 8 weeks or deadlock, the Energy Ombudsman can make binding decisions worth up to £10,000. It costs you nothing.
Common questions
Can I complain to Ofgem about Bulb Energy?
Not for individual disputes - Ofgem regulates the energy market but doesn't resolve personal complaints. Complain to Bulb Energy in writing first. If it's unresolved after 8 weeks (or they send a deadlock letter), escalate to the Energy Ombudsman, which is free and can make binding decisions worth up to £10,000.
Which ombudsman handles Bulb Energy complaints?
The Energy Ombudsman (Ombudsman Services: Energy) handles Bulb Energy complaints. It's free for consumers, and you can use it after Bulb Energy has had 8 weeks to resolve your complaint or has issued a deadlock letter.
How do I complain to Bulb Energy?
Put your complaint in writing with your account number, what went wrong, and the outcome you want. Keep copies of everything. Bulb Energy then has 8 weeks to resolve it before you can escalate to the Energy Ombudsman for free.
