Ofgem is the independent regulator for gas and electricity markets in Great Britain. It licenses energy suppliers, sets and reviews the energy price cap, and makes the rules that protect consumers — including support for vulnerable customers and the process when a supplier goes bust.
What it does — and doesn’t
Ofgem sets the standards suppliers must meet, but it does not resolve individual complaints. If you have a dispute with your supplier, you complain to the supplier first and then, after 8 weeks or a deadlock letter, take it to the free Energy Ombudsman — not Ofgem.
When to turn to it
Ofgem’s website is the authoritative place to understand the price cap, your rights as an energy customer, and schemes like the Warm Home Discount and the Great British Insulation Scheme (which closed on 31 March 2026).
