A three-year fixed business electricity contract at 24.8 pence per kWh, arranged through a broker, carried an undisclosed commission of 1.9 pence per kWh built into the unit rate. For a business using 180,000 kWh a year, that is 3,420 pounds a year, or 10,260 pounds over the term, paid to an intermediary the owner believed was free. That single number is why Entropy Business Energy exists.

This site analyses business energy and utility costs for small and medium-sized enterprises in the UK. Every article leads with the figure that matters, shows the full working in a table, and is willing to conclude that the deal on offer does not stack up. There is no cheerleading for switching, for fixing, for brokers or for suppliers, and the site takes no commission from any of them.

Coverage includes broker commission disclosure and how to demand it, out-of-contract and deemed rates, standing charges and the capacity charges hidden behind them, half-hourly metering, the mechanics of a fixed versus flexible contract, contract end dates and the rollover trap, and the reliefs and schemes that apply to eligible businesses. A contract end-date tracker and a commission disclosure guide are kept as standing resources.

Entropy Business Energy is edited by Peter Vance, who has spent many years analysing commercial energy pricing. It is an independent UK publication and does not provide advice on any specific business contract.
