Jot down a few questions to make the most of your conversation.
Why bills can rise even if you use the same amount
Gas and electricity bills can go up for reasons that are outside your control. Energy suppliers buy power and gas on wholesale markets, and those costs can change quickly. If wholesale prices rise, household bills often follow.
Your bill may also increase because of standing charges, which are fixed daily costs. These are paid whether you use much energy or not. If standing charges go up, your bill rises even when your usage stays the same.
Other common reasons your bill is higher
You may be on a variable tariff, which means your price can change when the supplier updates its rates. Fixed deals can also end, and when that happens you may move onto a more expensive standard tariff. That can cause a noticeable jump in monthly payments.
Seasonal use is another factor. In colder months, heating, lighting, and hot water use usually increase, especially in larger or older homes. Smart meter estimates can also be off, leading to unexpectedly high bills or catch-up charges.
What you can do straight away
Start by checking whether your bill is based on an actual meter reading or an estimate. If it is estimated, submit your own reading to make sure you are only paying for what you have used. This is one of the quickest ways to spot mistakes.
Compare your tariff with other deals on the market, especially if your fixed contract has ended. Contact your supplier to ask about cheaper options or payment plans. If your bills are hard to afford, ask whether you can spread payments more evenly across the year.
Ways to reduce your energy use
Small changes can make a difference. Lower your thermostat by even one degree, switch off appliances instead of leaving them on standby, and use LED bulbs where possible. Washing clothes at lower temperatures can also help cut electricity use.
At home, draught-proofing doors and windows can reduce heat loss. Closing curtains at dusk and only heating rooms you use often can also help. If you have a boiler or heating system, servicing it regularly can improve efficiency.
Where to get help if you are struggling
If you are finding it difficult to pay, speak to your supplier as soon as possible. Suppliers must consider payment plans and may be able to offer support if you are in financial difficulty. Do not wait until the debt builds up.
You can also seek independent advice from organisations such as Citizens Advice. They can help you understand your bill, challenge errors, and check whether you may qualify for extra support. If you think your meter or bill is wrong, ask for a full review.
