UK Energy Bills Are Rising Again: 15 Easy Ways to Cut Your Heating Costs This Winter 2026

Winter is approaching, and millions of households across Britain are once again thinking about the cost of keeping their homes warm.

From 1 October 2026, Ofgem's energy price cap for a typical household paying by Direct Debit will rise by 4%, from £1,663 to £1,723 a year based on typical gas and electricity consumption.

That works out at roughly £60 more a year, or about £5 more a month, if the new cap level were maintained for a full year.

However, the £1,723 figure is not a maximum household bill.

Your actual bill depends on how much energy you use.

So, if you are wondering how to save on energy bills UK this winter, reducing unnecessary consumption can still make a meaningful difference.

Here are 15 practical ways to reduce heating and energy costs without simply sitting in a freezing home.

What Is Happening to UK Energy Bills in October 2026?

Ofgem reviews the energy price cap every three months.

For the period from 1 October to 31 December 2026, the cap rises by 4% for a typical dual-fuel household paying by Direct Debit.

Average Direct Debit rates under the new cap are:

Electricity: 26.32p per kWh

Electricity standing charge: 54.83p per day

Gas: 7.97p per kWh

Gas standing charge: 29.68p per day

Actual rates vary by region, payment method and meter type.

Another significant change begins on 1 October: VAT is removed from domestic electricity until 31 March 2027, while gas continues to carry 5% VAT.

Despite that electricity tax reduction, higher gas costs contribute to the overall rise for a typical dual-fuel household.

The price cap applies to unit rates and standing charges on covered default tariffs. It does not mean you can use unlimited energy for £1,723.

Using more energy means paying more.

That is why small efficiency improvements can matter.

1. Set Your Thermostat to the Lowest Comfortable Temperature

Heating is one of the biggest areas to examine when learning how to save on energy bills UK.

Turning the thermostat extremely low is not appropriate for everyone, particularly where age, disability or health needs require a warmer home.

But many households may be able to avoid overheating rooms.

Energy Saving Trust says that for most people, the lowest comfortable thermostat setting is generally somewhere between 18°C and 21°C.

Turning a thermostat down from 22°C to 21°C could save an estimated £120 a year in Great Britain under its current assumptions.

Do not reduce your temperature below what is safe and comfortable for your household.

The goal is eliminating unnecessary heating, not being cold.

2. Don't Turn the Thermostat Up to Heat the House Faster

This is a common misconception.

Turning your thermostat from 20°C to 25°C does not make the house warm up faster.

The thermostat determines the temperature you want the room to reach.

On a cold day, your home may simply take longer to reach that temperature.

Choose a comfortable target instead of turning the thermostat much higher and forgetting to lower it afterwards.

3. Use Your Heating Timer Properly

There is little benefit in heating an empty house unnecessarily.

Use your heating programmer or timer around your normal routine.

For example, you may want heating before you wake up and around the time you return home.

If everyone leaves for work or school during the day, avoid automatically heating the entire house to the same level for hours when nobody is there.

Modern smart controls can make this easier because schedules can sometimes be changed remotely when your plans change.

A well-planned heating schedule is one of the simplest winter energy saving tips.

4. Turn Down Radiators in Rooms You Use Less

Not every room needs to be equally warm.

Thermostatic radiator valves, commonly called TRVs, allow you to control individual radiators.

Living rooms and frequently used spaces may need more heating.

A spare bedroom or rarely used room may need less.

Energy Saving Trust recommends aiming for the lowest TRV setting that keeps each room comfortable.

However, avoid allowing rooms to become so cold that you create comfort, damp or condensation problems.

5. Stop Heat Escaping Around Doors and Windows

Heating your house becomes more expensive if warm air constantly escapes while cold air enters.

Check for draughts around:

Windows.

External doors.

Floorboards.

Skirting boards.

Letterboxes.

Loft hatches.

Unused chimneys.

Simple draught-proofing can reduce unwanted heat loss.

Energy Saving Trust estimates that draught-proofing windows, floors and doors could save around £55 per year in Great Britain under its current assumptions.

DIY draught strips can be considerably cheaper than professional installation.

But do not block intentional ventilation such as air bricks, wall vents or trickle vents.

Homes still require appropriate ventilation to manage moisture and maintain indoor air quality.

6. Close Curtains When It Gets Dark

Curtains can provide another layer between a warm room and cold windows.

Close them in the evening to help retain heat.

Heavy or lined curtains can be particularly useful.

During sunny winter days, do the opposite.

Open curtains and blinds where sunlight can naturally warm a room.

Then close them as daylight disappears.

Make sure curtains do not completely cover radiators, because that can trap heat behind the curtain rather than allowing it to circulate effectively through the room.

7. Check Your Radiators Before Winter

If the top of a radiator remains cold while the bottom becomes warm, trapped air may be reducing its effectiveness.

Bleeding a radiator can release that trapped air.

Check your heating system before the coldest part of winter arrives rather than discovering a problem during a freezing week.

If you are unsure how to maintain your heating system safely, use the manufacturer's instructions or a qualified professional.

8. Don't Block Radiators With Furniture

A large sofa directly in front of a radiator can prevent heat circulating effectively around the room.

Where practical, leave enough space for warm air to circulate.

Also check whether long curtains are hanging directly over radiators.

You want the heat to warm the room rather than becoming trapped behind furniture.

Rearranging furniture costs nothing, making this one of the easiest ways to improve how your existing heating works.

9. Check Your Boiler Settings

Your boiler's flow temperature affects the temperature of water sent to radiators.

If it is unnecessarily high, lowering it may improve the efficiency of some systems.

However, the correct setting depends on your heating and hot-water setup.

Homes with a separate hot-water cylinder require particular care because hot-water temperatures need to be managed safely.

Do not simply copy a boiler temperature seen in a social-media video.

Consult your boiler manual or seek appropriate professional advice if you are unsure.

10. Get Your Boiler Serviced

An inefficient or poorly maintained boiler can cost more to operate and may also become unreliable.

Energy Saving Trust recommends servicing a boiler or heat pump annually to help ensure it is operating correctly.

If you rent your home, your landlord is generally responsible for arranging the required gas safety checks and relevant servicing responsibilities.

If you own the property, consider arranging maintenance before the coldest weather arrives.

A winter breakdown can be both inconvenient and expensive.

11. Reduce Hot-Water Waste

Your energy bill is not just about radiators.

Heating and hot water together account for more than half of a typical home's energy use, according to Energy Saving Trust.

Think about where hot water is being wasted.

Shorter showers can reduce both water and energy consumption.

Avoid leaving hot taps running unnecessarily.

Fix dripping hot-water taps.

Only heat the amount of water you actually need when using a kettle.

Small actions become more meaningful when repeated every day.

12. Wash Clothes at Lower Temperatures Where Appropriate

Many everyday laundry loads can be washed effectively at lower temperatures, depending on the fabric, detergent and hygiene requirements.

Always follow garment and detergent instructions.

You can also reduce energy use by waiting for a suitable load rather than repeatedly running nearly empty washing machines.

When weather and space allow, air-drying clothes can reduce tumble-dryer use.

During winter, however, indoor drying needs sensible ventilation to prevent excessive moisture and condensation.

13. Switch Off Lights and Unnecessary Devices

Heating receives most of the attention during winter, but electricity consumption throughout the house still matters.

Turn lights off when leaving empty rooms.

Energy Saving Trust estimates this simple habit can save around £7 a year in Great Britain.

Replace inefficient bulbs with LEDs as older bulbs fail.

You can also look for devices consuming electricity unnecessarily when left running.

One action may save only a small amount.

A collection of good habits across an entire year can make a bigger difference.

14. Use Your Smart Meter Information

A smart meter does not automatically reduce your energy bill.

But the information it provides can help you understand your consumption.

Look for patterns.

Does usage rise dramatically at a particular time?

Are you heating the house for longer than expected?

Does one appliance appear to use much more electricity than you realised?

Treat the display as an information tool rather than something to worry about constantly.

The goal is identifying waste that you can realistically reduce.

15. Compare Your Energy Tariff

The price cap does not mean every household should automatically remain on a default tariff.

Ofgem says around 35% of households are currently on fixed tariffs and therefore will not be affected by the October price-cap increase while their fixed deal applies.

Check your existing tariff before switching.

Look at:

Unit rates.

Standing charges.

Contract length.

Exit fees.

Payment method.

Whether prices are fixed or variable.

Estimated annual cost based on your actual usage.

Do not choose a tariff purely because the advertised monthly Direct Debit looks cheaper.

A Direct Debit payment is not the same thing as the underlying cost of the energy you consume.

What Does the £1,723 Energy Price Cap Really Mean?

This deserves repeating because it is frequently misunderstood.

The £1,723 Ofgem price cap is not a limit on your total bill.

It is an illustration based on typical consumption and capped rates for a representative dual-fuel household paying by Direct Debit.

A household using significantly more energy can pay significantly more than £1,723.

A household using less can pay less.

Think of the cap primarily as a limit on covered unit rates and standing charges, rather than a promise about your final annual bill.

Should You Fix Your Energy Tariff Before Winter?

There is no universal answer.

A fixed tariff can provide price certainty.

However, whether a particular deal is good value depends on its rates, standing charges, duration, exit fees and what happens to future variable prices.

Before switching, compare the entire deal with your existing tariff.

Consider your actual annual usage rather than relying only on a supplier's headline estimate.

Remember that predicting future wholesale energy prices is difficult.

A fixed tariff provides certainty, not a guarantee that it will turn out to be the cheapest option.

Five Free Things You Can Do Today

If you do not want to spend money on home improvements, start with changes that cost nothing:

1. Review your thermostat setting.

2. Adjust your heating schedule.

3. Turn down TRVs in less-used rooms where appropriate.

4. Move furniture away from radiators.

5. Close curtains after dark and open them when winter sunshine can warm the room.

The best how to save on energy bills UK strategy does not always require buying new technology.

Reducing waste is the first step.

Low-Cost Improvements Worth Considering

If you have a small budget, look for areas where inexpensive improvements could reduce heat loss.

Possibilities include:

Draught-excluder strips.

A letterbox draught excluder.

Radiator reflector panels where suitable.

LED bulbs.

Hot-water tank insulation where appropriate.

Thicker curtains.

Pipe insulation.

Always make sure any DIY modification is appropriate for your property and does not interfere with required ventilation or safety equipment.

Don't Block Ventilation to Save Heat

This is particularly important.

You may notice cold air near a ventilation grille and think covering it will save money.

Do not automatically block intentional ventilation.

Ventilation helps control moisture, condensation and indoor air quality, and some ventilation is required for safety.

Draught-proof unwanted gaps, but leave necessary ventilation functioning.

If you are unsure whether an opening is intentional, seek appropriate advice before sealing it.

What If You Are Struggling to Pay Your Energy Bill?

Energy saving can help, but there is a limit to how much a household can cut.

If you are struggling to afford energy, contact your supplier rather than ignoring the problem.

Ask what support and repayment options may be available.

Also check current government schemes and independent energy or debt-advice services to see whether you qualify for assistance.

Eligibility and support programmes can change, so always use current official information.

Do not leave yourself dangerously cold because you are frightened of the bill.

Renters Can Save Energy Too

Renters may not be able to replace windows or install major insulation, but there are still options.

You can:

Use heating controls efficiently.

Close curtains at night.

Move furniture away from radiators.

Use appropriate removable draught-proofing.

Turn off unused lights.

Monitor energy use.

Discuss significant insulation or heating problems with your landlord.

Avoid making permanent alterations without permission.

Prepare Your Home Before the Coldest Weather Arrives

September is a useful time to prepare.

Check whether the heating actually works.

Look for obvious draughts.

Learn how your timer works.

Check radiator valves.

Find your boiler manual.

Review your energy tariff.

If maintenance is needed, arranging it before winter may be easier than waiting for the first major cold spell.

Energy Saving Trust notes that Britain's main heating season typically runs from around October through March or April.

Preparation now can therefore prevent problems later.

Final Thoughts

UK households are heading towards another winter with energy costs firmly in focus.

From 1 October 2026, Ofgem's typical annualised price-cap figure for a dual-fuel Direct Debit household rises to £1,723.

You cannot control wholesale energy markets.

But you can control some of the energy wasted in your own home.

If you are searching for how to save on energy bills UK, begin with the simplest changes.

Set heating to the lowest comfortable temperature for your household.

Use timers and radiator controls properly.

Stop unnecessary draughts while maintaining safe ventilation.

Avoid blocking radiators.

Reduce hot-water waste.

Monitor your consumption.

And check whether your current energy tariff still makes sense.

No single tip will magically eliminate a winter energy bill.

But several sensible changes working together can reduce waste while helping you keep your home comfortable.

This winter, the aim should not be to stop using energy — it should be to avoid paying for energy you do not need.
