Check Why the Bill Has Gone Up
If your gas or electricity bill has increased unexpectedly, start by checking whether your usage has changed. Cold weather, working from home, or having extra people in the house can all raise energy use.
Also look at your meter readings and billing period. A bill based on estimated readings can be much higher or lower than expected if the estimate was inaccurate.
Compare the Charges on Your Statement
Read through your bill carefully and look at the unit rate, standing charge, and any fixed fees. In the UK, energy prices can change if you are on a variable tariff or if a fixed deal has ended.
If the increase seems unusual, compare it with your previous bills. This can help you spot whether the issue is higher usage, a price rise, or a possible billing error.
Submit an Accurate Meter Reading
If your bill is estimated, send your supplier an up-to-date meter reading. This should help them issue a corrected bill based on what you actually used.
Take a clear photo of your meter if possible, especially if you need to challenge the amount later. Keep a record of the date and reading you submitted.
Contact Your Energy Supplier
If the bill still does not make sense, contact your supplier and ask for a full explanation. Be ready to give your account number, meter readings, and copies of any bills you think are wrong.
You can ask them to review the charges and check for any billing mistakes. If the supplier agrees there has been an error, they should correct it.
Look for Ways to Reduce Future Bills
Small changes can help bring bills down over time. Turn appliances off standby, use lower heating settings where possible, and only run washing machines or dishwashers with full loads.
It can also help to check whether your tariff still suits your household. A different deal may be available, but make sure you compare exit fees and contract terms before switching.
Get Help If You Are Struggling to Pay
If the rise means you cannot afford your bills, contact your supplier as soon as possible. Many suppliers offer payment plans, temporary support, or advice for customers in difficulty.
You may also be able to get help through government schemes or local welfare support, depending on your circumstances. If you are in serious trouble, seek advice from a free debt or energy charity such as Citizens Advice.
Frequently Asked Questions
Common causes include higher usage, seasonal weather changes, increased utility rates, faulty appliances, heating or cooling equipment running longer, billing errors, and changes in household occupancy or routines.
Compare your current bill with past bills, review meter readings, check the billing period, and inspect your daily usage patterns. If the numbers do not match your usage or the meter reading, contact your utility provider to investigate a possible billing error.
Start by reviewing the bill details, checking meter readings, and comparing recent usage to previous months. Then look for changes in weather, appliances, or household habits. If the increase still seems unexplained, contact the utility provider.
Yes. Malfunctioning appliances, especially heaters, water heaters, refrigerators, dryers, or air conditioners, can consume more energy than normal and raise both gas and electricity bills unexpectedly.
Cold weather can increase gas use for heating, while hot weather can raise electricity use for air conditioning and fans. Extended periods of extreme weather often lead to higher energy consumption and larger bills.
Yes. Estimated readings can make a bill appear higher or lower than actual usage. If estimates are later corrected, you may see a sudden increase in a future gas or electricity bill.
Gather copies of the bill, recent meter readings, and any relevant photos or records. Contact the provider, explain the discrepancy, and request a review or recalculation. If needed, escalate the complaint through the utility's formal dispute process.
Record the meter readings on your gas and electricity meters, compare them with the bill, and make sure the meter numbers match your account. If possible, note the date and time of the reading and take photos as evidence.
Yes. A switch to a higher rate, the end of a fixed-price plan, changes in standing charges, or a new tariff can all cause unexpected increases in gas and electricity bills.
Leaving lights on, using heating or cooling for longer periods, taking more hot showers, running appliances more often, and keeping devices on standby can all increase energy consumption and raise bills.
Yes. A gas leak, electrical fault, or damaged wiring can sometimes cause unusual energy use or safety issues. If you suspect a leak or fault, contact your utility provider or emergency services immediately and do not ignore the problem.
Use energy more efficiently by lowering thermostat settings, sealing drafts, turning off unused devices, switching to LED lighting, maintaining appliances, and monitoring usage regularly to identify waste.
Yes. Smart meters can help you track real-time or near-real-time consumption, making it easier to spot unusual spikes and identify when and how the extra usage is happening.
Yes. Sometimes a provider may issue a catch-up bill if earlier usage was underbilled, estimated too low, or not charged correctly. This can make a later gas or electricity bill seem unexpectedly high.
Contact your provider as soon as the increase seems unusual, especially if the bill is much higher than normal, the meter reading appears incorrect, or you suspect a billing error, appliance fault, or leak.
Yes. More people at home, guests staying over, remote work, children being home more often, or new appliances can all increase usage and lead to higher gas and electricity bills.
Keep copies of bills, meter reading photos, provider emails, complaint records, tariff notices, and notes about appliance changes or weather conditions. These records can help explain or challenge the increase.
Yes. Tampering or theft can distort meter readings and lead to unusual bills or safety risks. If you suspect this, contact your utility provider immediately and avoid investigating the meter yourself.
Monitor usage for at least one or two billing cycles to see whether the increase was temporary or ongoing. Regular checks can help confirm whether the issue is resolved or still present.
You generally have the right to request an explanation, ask for meter verification, dispute incorrect charges, and seek a corrected bill if an error is found. The exact process depends on your provider and local consumer rules.
