A quick checklist for managing your utility bills

What is a utility bill?

A utility bill covers essential services such as electricity, gas, and water. It shows how much you’ve used, how much it costs, and any fixed charges. Understanding your bill helps you manage your budget and avoid unexpected costs.

What makes up your energy bill

Your energy bill is usually made up of two main parts: the unit rate and the standing charge. The unit rate is what you pay per kilowatt-hour of energy used, while the standing charge is a daily cost for being supplied, regardless of usage. At Fuse Energy, all rates are quoted inclusive of VAT at 5%.

Why your bill may change

Your bill, if you’re on a variable Direct Debit (DD), can change depending on how much energy you use and the time of year. Higher usage in winter usually leads to higher bills, while summer usage is typically lower. If your bill is estimated rather than based on actual readings, it may not reflect your true usage. If you’re on a fixed DD, however, you’ll be paying the same amount each month.

Using smart meters for accurate billing

Smart meters should send readings automatically to your energy supplier, ensuring your bills are based on your actual usage. This helps avoid large catch-up bills and gives you better visibility of your energy consumption.

If you have a manual meter, submitting regular readings helps keep your bills accurate.

Comparing energy prices

Comparing energy prices can help you find a better deal. While comparison tools are useful, it’s important to look at the full cost, including unit rates, standing charges, and exit fees. Switching to the right tariff for you can help you avoid hidden costs and stay in control of your spending.

Common mistakes to avoid

Many people pay more than necessary by not reviewing their bills. Not checking whether your bill is estimated, failing to submit readings, or ignoring more suitable tariff options can all increase costs. Staying informed helps avoid these issues.
