How the UK Energy Market Works
– Deregulated

The UK energy market is fully deregulated, meaning households and businesses can choose their energy supplier. While the infrastructure that delivers power to your home is fixed, who you buy your energy from is up to you.

UK Energy Market Summary

These companies produce energy using sources like gas, wind, solar, and nuclear (e.g., EDF, SSE Renewables).
