Energy Bill Too High? Here is What to Check First

Opening an energy bill that is noticeably higher than usual is never a pleasant experience. Your first instinct might be to phone your supplier and demand an explanation, but before you do, there are a few things worth checking yourself. The answer is often simpler than you think.

Estimated vs Actual Readings

This is the number one reason for unexpectedly high bills. If your supplier has been using estimated meter readings rather than actual ones, the estimates may have been too low for months, meaning you were underpaying. When an actual reading finally comes through, you get hit with a catch-up bill that covers the difference. Check whether your recent bills say "estimated" or "actual" next to the meter reading. If they have been estimated, submit a reading yourself and ask your supplier to recalculate.

Has Your Fixed Tariff Ended?

If you were on a fixed-rate energy deal and it has expired, you will have been moved onto your supplier's standard variable tariff, which is almost always more expensive. This is similar to what happens with broadband. Check your account or a recent bill to see what tariff you are on. If your fix has ended, it is time to look for a new deal, either with your current supplier or elsewhere.

Standing Charges

Every energy bill includes a standing charge, which is a daily fixed fee you pay regardless of how much gas or electricity you use. Standing charges have increased significantly in recent years. Check what yours is and compare it with what other suppliers are offering. Some tariffs have lower standing charges but higher unit rates, which could work out cheaper if your usage is low.

Compare Your Usage

Look at the actual kilowatt hours (kWh) on your bill and compare them with the same period last year. If your usage has genuinely gone up, think about what might have changed. A colder winter, working from home more often, a new appliance, or a teenager who has discovered hour-long showers can all make a meaningful difference. If your usage looks similar but the bill is higher, the issue is likely your tariff or unit rate rather than your habits.

Smart Meters and Monitoring

If you do not have a smart meter, getting one fitted is free and can help you see your usage in real time. This makes it much easier to identify what is costing you money. Even something as simple as checking the in-home display after turning on different appliances can be eye-opening. That tumble dryer is not cheap to run.

Switching Suppliers

If your tariff is uncompetitive, switching is easier than ever. Ofgem's price cap sets a maximum for standard variable tariffs, but fixed deals from smaller suppliers can sometimes undercut it. Use comparison sites, check what is available, and do not feel any obligation to stay with your current supplier out of loyalty.

Keeping your energy documents and bills in one place makes it much simpler to spot when things change. Orlo helps you store your energy bills and track what you are paying, so you can quickly compare one period to the next and catch any unexpected jumps before they become a bigger problem.
