Energy bills are one of the most frustrating things to budget for. They go up in winter, drop in summer, change when Ofgem adjusts the price cap, and then your supplier sends you a letter saying your direct debit is going up by another thirty pounds a month. It makes forward planning feel almost impossible — and for a lot of households, it is the one spending category that repeatedly throws the whole budget off.
Work from an annual average, not this month's bill
The simplest way to smooth out the unpredictability is to stop thinking about what you owe this month and start thinking about what you pay across a full year. Add up your last twelve months of energy bills — you can usually find these in your online account or app. Divide that total by twelve. That is the number to use in your monthly budget for energy. It will be higher than your summer bills and lower than your winter ones, but it gives you a consistent figure to plan around.
Build a buffer for the colder months
Even with an average, most households find October through to March stretches the budget. Heating use goes up, there are fewer daylight hours, and the cost per unit of energy is often higher. If you can, put a little extra aside in August and September — even £20 or £30 a month into a separate pot — so you have something to draw on when the bills rise. Think of it as pre-paying for winter before it arrives.
Check what your supplier has set for your direct debit
Energy suppliers are required to base your direct debit on your estimated usage, but they do not always get this right. Some households end up overpaying and building up large credits with their supplier. Others are underpaying and then face a shock at the annual review. Log into your account, check your current meter readings against what the supplier estimates, and ask them to recalculate your direct debit if it looks off. A credit sitting with your energy company is not helping you with this month's rent or food bill.
Do not forget standing charges
It is easy to focus entirely on the unit rate — the price per kilowatt hour of gas or electricity — and forget that standing charges add up regardless of how much energy you use. A daily standing charge of around 60p for electricity and 30p for gas works out to roughly £33 a month before you have used anything at all. Include this in your budget calculation so the figure reflects your actual bill, not just your usage costs.
Review your tariff once a year
With the energy market shifting regularly, it is worth checking once a year whether switching tariff or supplier would save you money. Comparison sites can show you what is available for your postcode and typical usage. The savings are not always dramatic, but over a year they can add up. If you are on a default variable tariff and have not looked at alternatives in a while, there may be a cheaper option worth considering.
