Business Energy Bills Explained

Every business energy bill is built on two core charges: the unit rate and the standing charge. The unit rate is what you pay per kilowatt-hour (kWh) of energy you consume. The standing charge is a fixed daily fee that covers the cost of supplying energy to your premises — including meter maintenance, distribution, and infrastructure. Together, these two charges make up the majority of your bill. Understanding both is essential: a lower unit rate doesn't always mean a lower bill if the standing charge is high.

The Climate Change Levy is a government tax applied to energy used by businesses. It's charged per kWh on electricity and gas, and appears as a separate line item on your bill. The rate changes annually and differs between electricity and gas. Some businesses are exempt from CCL — for example, if you're a charity or if your energy use is very low. CCL is added on top of your energy charges and is subject to VAT, so it's a real cost that should be factored into your energy budgeting.

Business energy is subject to VAT at the standard rate of 20% — unlike domestic energy, which qualifies for the reduced rate of 5%. This is a significant difference and one that catches many new business owners by surprise. However, there are exceptions: businesses with very low energy consumption (using less than 33 kWh of electricity or 145 kWh of gas per day on average) may qualify for the reduced 5% rate. A good broker or accountant can advise whether your business qualifies.

Beyond the core charges, your bill may include additional costs that aren't immediately obvious. These can include meter rental charges, data collection fees (for half-hourly meters), capacity charges, reactive power charges, and late payment fees. Some brokers also apply administration charges for changes to your account or contract. If you're unsure what a charge is for, ask your broker for an explanation. Billing errors do occur, and identifying them can lead to meaningful refunds.

Your energy bill contains the information you need to identify savings. Start by checking your annual consumption (in kWh) — this is what brokers use to price your contract. Compare your unit rate and standing charge against current market rates. If you're on a deemed or out-of-contract rate, the difference could be 30–60% compared to a contracted rate. Check whether you're being billed correctly for your meter type. And if your consumption has changed significantly (up or down), a new contract based on your updated usage profile could unlock better rates.
