Energy bills can take a significant share of a household's monthly budget, especially during the colder months.
But reducing your gas and electricity costs doesn't always require expensive home improvements or buying new appliances.
Sometimes, understanding your energy tariff, adjusting your heating controls and changing everyday habits can make a useful difference.
In this guide, we'll explain seven practical ways UK households can manage energy costs, avoid unnecessary spending and find help when bills become difficult to afford.
1. Understand What You're Actually Paying for Energy
Before trying to reduce your energy bill, check how your supplier calculates it.
Your gas and electricity bill usually includes two main charges:
Unit rate: The amount you pay for each kilowatt-hour (kWh) of energy you use.
Standing charge: A daily charge you normally pay even if you use no energy that day.
According to Ofgem, the energy price cap for 1 October to 31 December 2026 is £1,723 per year for a typical household using gas and electricity and paying by Direct Debit in England, Scotland or Wales.
For a customer on a standard variable tariff paying by Direct Debit, the average rates across Great Britain during this period are:
Electricity
Unit rate: 26.32p per kWh
Daily standing charge: 54.83p
Gas
Unit rate: 7.97p per kWh
Daily standing charge: 29.68p
These are national averages. Your actual rates can vary by region, tariff and payment method.
Important: The £1,723 figure is not the maximum you can be billed. Households using more energy can pay considerably more.
Electricity VAT has also been removed for the period 1 October 2026 to 31 March 2027, while gas continues to attract 5% VAT.
Practical tip: Open your latest energy bill and identify your unit rates, daily standing charges and estimated annual energy usage. These figures are more useful when comparing suppliers than your monthly Direct Debit alone.
Read the Ofgem energy price cap and regional rates.
2. Check Whether You're on the Right Energy Tariff
Staying with the same energy supplier doesn't always mean you're getting the most suitable deal.
Your supplier may offer different tariffs, including fixed-rate and standard variable options.
A fixed-rate tariff generally fixes the price you pay per unit of energy for an agreed period. It doesn't mean your total bill stays fixed regardless of usage.
A standard variable tariff can change when prices change, subject to applicable price-cap protections.
Before switching, compare:
Electricity and gas unit rates
Daily standing charges
Your estimated annual cost based on actual usage
Whether there are exit fees
The length and conditions of any fixed deal
For example, a tariff advertising cheaper electricity might have a higher standing charge. The best option depends on how much energy your household uses.
Practical tip: Ask your current supplier whether it has a cheaper suitable tariff before moving elsewhere.

3. Use Your Heating Controls More Efficiently
Heating and hot water account for a large proportion of energy used in many UK homes.
Learning to use your existing heating controls properly can help reduce unnecessary consumption.
The Energy Saving Trust recommends setting your room thermostat to the lowest comfortable temperature, typically around 18-21°C for many households.
However, some people, including older people, young children and those with certain health conditions, may need a warmer home.
Here are some useful checks:
Make sure your heating timer matches when your household needs warmth.
Learn what your thermostat and radiator controls actually do.
Avoid heating unused rooms unnecessarily, while maintaining safe temperatures and preventing damp.
Keep radiators clear of furniture and other obstructions where possible.
Follow the correct operating guidance for your heating system.
Important: Homes with heat pumps often benefit from different heating schedules than homes with conventional boilers. Don't automatically apply boiler advice to a heat pump.
Practical tip: Review your heating schedule this week. Check whether it's running at times when you don't need it.

4. Reduce Draughts Without Blocking Essential Ventilation
Cold air entering through unnecessary gaps can make your home feel uncomfortable and increase heating demand.
Draught-proofing can help, particularly in older properties.
Check for unwanted gaps around:
External doors
Window frames
Letterboxes
Floorboards and skirting boards
Depending on the problem, suitable draught-proofing strips, seals or door brushes may help.
However, do not block trickle vents, airbricks, extractor fans or ventilation openings needed by gas appliances.
Ventilation is important for air quality, reducing condensation and operating some appliances safely.
Practical tip: Walk around your home on a cold day and identify noticeable draughts. Before buying anything, check whether the problem can be resolved safely with inexpensive materials.
Read the Energy Saving Trust's draught-proofing guidance.
5. Cut Unnecessary Electricity Use in Everyday Activities
Small changes to everyday routines can help reduce electricity consumption without significantly affecting comfort.
Wash clothes at lower temperatures when appropriate.
Try a 30°C cycle for suitable laundry, following garment labels and hygiene requirements. Running your washing machine only when you have an appropriate load can also reduce unnecessary washes.
Switch off unused appliances.
Some appliances continue using electricity in standby mode. Switch off equipment when practical and safe, but keep essential appliances such as fridges and freezers running.
Use your dishwasher efficiently.
Where suitable, wait until you have a full load rather than running multiple partially filled cycles.
Consider how you use hot water.
Shorter showers can reduce the energy needed to heat water, particularly in homes where water heating contributes significantly to energy bills.
Practical tip: Choose two habits your household can realistically change and maintain them consistently.
You can find further ideas in the Energy Saving Trust's quick energy-saving tips.
6. Use Your Smart Meter or Energy Display to Understand Your Usage
A smart meter can help provide more accurate energy bills by automatically sending readings to your supplier when it is working correctly.
An in-home display can also show information about how much energy you're using.
For example, you might notice an increase in electricity consumption when several high-powered appliances are operating.
You can use this information to identify where changes may be worthwhile.
If you already have a smart meter but no working in-home display, ask your energy supplier what options are available.
Remember that a smart meter doesn't automatically reduce your energy bills. Its benefit is helping you understand usage and manage it more effectively.
Practical tip: Compare your energy consumption across different days or weeks. Focus on the energy used in kWh, rather than relying only on the amount collected through your monthly Direct Debit.

7. Check Whether You're Eligible for Energy-Bill Support
If your household is struggling to afford energy, there may be support available.
One example is the Warm Home Discount, which offers an eligible household a one-off £150 discount on its energy bill for winter 2026–27.
Eligibility depends on factors including your circumstances, qualifying benefits, your supplier and where you live.
For England and Wales, the 2026–27 qualifying conditions include receiving certain means-tested benefits on the specified qualifying date and meeting the scheme's other requirements.
Scotland has different eligibility arrangements, and the scheme does not operate in Northern Ireland.
You should check the official guidance rather than assuming everyone qualifies.
Find out more from the GOV.UK Warm Home Discount Scheme.
What if you cannot afford your bill?
Contact your energy supplier as early as possible.
You can explain your circumstances and ask about an affordable payment arrangement and any support the supplier offers.
Citizens Advice also provides free guidance on dealing with energy debts and discussing repayment plans.

Frequently Asked Questions
Does the energy price cap mean my annual bill cannot exceed £1,723?
No. That figure represents a typical household's annualised cost at the applicable capped rates. Your actual bill depends on how much energy you use and the rates that apply to your household.
Is it always cheaper to leave the heating on all day?
No. The best approach depends on your heating system, property and household needs. Conventional central heating and heat pumps can require different operating strategies.
Will a smart meter automatically save me money?
Not necessarily. A smart meter can make your energy use easier to understand, but savings depend on the changes you make.
Should I switch energy suppliers immediately?
Not without comparing tariffs carefully. Consider unit rates, standing charges, estimated annual costs and any exit fees.
