How long does an energy company have to resolve my complaint?

Energy suppliers have 8 weeks to resolve your complaint. After that, you can escalate to the Energy Ombudsman for free.

Can my energy supplier back-bill me for years of usage?

No, under Ofgem's back-billing rules, suppliers cannot charge for unbilled energy more than 12 months old if the delay was their fault.

What is the Energy Ombudsman and is it free?

The Energy Ombudsman is a free, independent dispute resolution service. They can award up to £10,000 in compensation and make binding decisions on suppliers.
