By Branch² Intelligence Desk · Checked against primary sources 11 October 2026

Part of a business energy bill is set outside the wholesale market: the charges for balancing and running the transmission grid, published by the system operator NESO, and the Climate Change Levy, set by government. If your contract renews this autumn, these are the published charges behind the price you are quoted.

The household price cap that makes the headlines is for domestic customers. Where an official statement below is about households, it is labelled that way.
