How to Heat Your Home for Less This Winter
Keeping your home warm during a British winter can be expensive, especially when energy bills are already taking a large part of the household budget. But spending more on heating doesn't always mean you'll feel any warmer.
Small draughts, poorly positioned curtains, inefficient heating settings and choosing the wrong type of electric heater can all mean you're spending money unnecessarily.

The good news is that some of the most effective improvements cost very little, and others are completely free. By understanding where your home loses heat and how your heating system works, you can make your existing energy go further.
In this guide, we'll look at practical ways to reduce heating costs, compare different heating methods and keep your home comfortable throughout winter. Everything is focused on sensible, affordable improvements that ordinary UK households can make.
How Do You Stop Heat Escaping From Your Home?
Before spending money on additional heating, it's worth looking at what happens to the warmth you're already paying for.
Even an efficient central heating system can struggle to maintain a comfortable room temperature when cold air is continually entering through doors, windows and other gaps.
In older British homes, draughts can be particularly noticeable around wooden window frames, floorboards, letterboxes and external doors. Several small gaps can combine to make a room feel considerably colder.
Find and Fix Unwanted Draughts
On a cold, windy day, run your hand slowly around the edges of a closed window. You may be able to feel cold air entering through a worn seal or a small gap in the frame.
Repeat the process around external doors, paying particular attention to the bottom of the door and the letterbox.
Once you've identified the problem, there are several inexpensive ways to improve it.
- Self-adhesive draught strips: Useful for sealing small gaps around suitable doors and windows.
- Draught excluders: Help reduce cold air entering beneath internal and external doors.
- Letterbox brushes: Can reduce unwanted airflow through the front door.
- Temporary fabric draught excluders: An old towel, jumper or rolled-up blanket can provide a completely free solution for certain gaps.
Many of these improvements are suitable for rented properties because they don't require permanent alterations.
Important: Draught-proofing means dealing with unwanted gaps, not blocking purpose-built ventilation.
Keep ventilation openings clear, particularly in kitchens, bathrooms and rooms containing appliances that require ventilation. A home still needs fresh air to manage moisture and maintain a healthy indoor environment.
Reducing draughts can help your existing heating maintain a comfortable temperature without continually compensating for cold air entering the room.
Is It Cheaper to Heat One Room or the Whole House?
If you spend most evenings in your living room, heating just that room might seem like the obvious way to save money.
And sometimes it is.
But the answer depends on your existing heating system, the type of heater you're considering and how much energy each option actually uses.
How Much Does an Electric Heater Cost to Run?
Electric heaters are commonly rated in watts or kilowatts. A typical portable fan heater, ceramic heater or oil-filled radiator might have a maximum output of 2,000 watts, equivalent to 2 kilowatts.
For a simple illustration, let's use an electricity price of 26p per kilowatt-hour.
A 2kW heater running continuously at maximum power would use 2kWh of electricity every hour.
| Running Time | Electricity Used | Approximate Cost |
|---|---|---|
| 1 hour | 2 kWh | 52p |
| 2 hours | 4 kWh | £1.04 |
| 3 hours | 6 kWh | £1.56 |
| 5 hours | 10 kWh | £2.60 |
| 30 days at 3 hours daily | 180 kWh | £46.80 |
These are illustrative electricity costs using 26p/kWh, excluding standing charges. They are not a live tariff quote. Actual costs depend on your current tariff and how often the heater runs at full power.
A heater with a thermostat may switch itself on and off once the room reaches the desired temperature, reducing its electricity consumption.
Is Gas Central Heating Cheaper?
Gas generally costs less per kilowatt-hour of fuel than electricity under typical domestic tariffs.
For example, at an illustrative gas price of 8p per kilowatt-hour, the fuel needed for a gas boiler can be considerably cheaper than the same amount of electricity used by a conventional resistance heater.
However, a gas boiler isn't perfectly efficient, and a central heating system may be warming several rooms rather than just one.
That means a small electric heater warming one room for a short period can sometimes cost less overall than running central heating throughout a larger property.
Equally, replacing your gas central heating with multiple portable electric heaters could increase your energy bills substantially.
Do Ceramic and Oil-Filled Radiators Use Less Electricity?
Ordinary electric fan heaters, ceramic heaters and oil-filled radiators all work by converting electricity into heat.
If two conventional electric heaters consume the same amount of electricity, they'll produce broadly the same amount of heat.
The main differences are how quickly they distribute warmth, how they control temperature and how comfortable they make a particular space feel.
An oil-filled radiator may continue releasing stored heat after switching off, while a fan heater can warm the surrounding air more quickly. Neither produces extra energy for free.
What about heat pumps?
Heat pumps work differently from ordinary electric resistance heaters. They move heat rather than simply generating it through an electrical heating element, allowing them to deliver substantially more heat energy than the electricity they consume.
If your home uses a heat pump, the comparison with portable electric heating is very different.
The most economical approach depends on your property and heating system. Before buying another heater, compare the cost of using your existing central heating more selectively.
Do Thermal Curtains and Radiator Reflectors Really Work?
Windows are often among the coldest surfaces in a room, particularly in older properties with less effective glazing.
Even when the air temperature is comfortable, sitting beside a large cold window can make you feel chilly.
There are several inexpensive ways to improve comfort without changing your heating system.
Use Curtains to Keep More Warmth Inside
During daylight hours, open curtains where sunshine can enter the room. Solar energy passing through the glass can provide some useful free warmth.
When the sun goes down, close the curtains to create an additional insulating layer between the room and the cold window.
Thick, well-fitting thermal curtains can be particularly useful with older windows, but ordinary curtains can still help.
If replacing your curtains isn't affordable, an existing spare blanket may provide an additional temporary layer over a particularly cold window.
Keep fabrics away from radiators and ventilation openings, and uncover the window regularly so condensation doesn't remain trapped against the glass.
Don't Trap Heat Behind Your Curtains
One common problem is having long curtains hanging directly over a radiator.
When the heating is running, some of the warmth can become trapped between the curtain and the window instead of circulating into the room.
Where possible, arrange the curtains so they insulate the window without covering the radiator.
Are Radiator Reflector Panels Worth Buying?
Radiator reflector panels are designed to reduce heat loss into the wall behind a radiator.
They are most useful behind radiators fitted to poorly insulated external walls, where some heat would otherwise be lost through the building fabric.
Reflector panels generally offer less benefit behind radiators on internal walls, because much of that heat remains within the home anyway.
Before buying a pack for every radiator, identify which radiators are positioned against external walls and consider whether those walls are already well insulated.
It's a good example of how a small, targeted improvement can be more worthwhile than buying the same product for every room.
How Can You Reduce Central Heating Costs?
Many households can improve the way their central heating works without replacing any equipment.
The first step is to consider when and where you actually need warmth.
Perhaps you're downstairs in the morning, out during the afternoon and then spending most of the evening in the living room.
Heating every room equally throughout that period may be unnecessary.
Make Better Use of Thermostatic Radiator Valves
Thermostatic radiator valves, often called TRVs, allow you to control the temperature of individual rooms when the heating system is running.
You could keep the living room warmer during the evening while setting a spare bedroom to a lower temperature.
The aim is to distribute warmth according to how the household uses each room.
There is no need to allow unused areas to become excessively cold or damp. A modest background temperature may still be appropriate, particularly in older properties.
Adjust Your Main Room Thermostat
Your main thermostat controls when the heating system needs to operate to reach the selected temperature.
If the setting is higher than necessary, the system will use more energy to maintain that temperature.
For many households, a room temperature somewhere around 18°C to 21°C provides reasonable comfort, although personal circumstances and individual needs vary.
Try making small adjustments rather than immediately turning the thermostat down several degrees.
You may find that a slightly lower temperature feels perfectly comfortable after reducing draughts and improving your curtains.
Practical approach: Change one heating setting at a time and compare how your home feels over several days.
Where possible, also compare your energy consumption across days with similar outdoor temperatures. This makes it easier to identify which adjustments are genuinely worthwhile.
Concentrate Warmth Where You Need It
If the family spends most evenings in one room, keeping that room comfortably warm can be a sensible approach.
Closing the internal door helps reduce the movement of warm air into hallways and other areas of the property.
Combine that with suitable radiator settings, effective curtains and draught-proofing, and you may be able to stay comfortable without increasing the overall heating temperature.
Is It Cheaper to Leave Your Heating On All Day?
This question comes up almost every winter, and the answer depends partly on the type of heating system installed in your home.
With a typical gas boiler and radiator system, maintaining a warm indoor temperature throughout the day means continually replacing heat escaping through the building.
When the heating is switched off or reduced, the indoor temperature gradually falls. As the difference between indoor and outdoor temperatures becomes smaller, the rate of heat loss generally decreases.
Although energy will be needed to warm the property again later, reducing the heating during periods when it isn't needed will generally use less energy than maintaining the same higher temperature all day.
Why Heat Pumps Can Be Different
Heat pumps often operate efficiently when delivering heat at relatively low temperatures for extended periods.
Large temperature setbacks followed by rapid reheating can reduce efficiency in some installations.
For that reason, settings suitable for a gas boiler may not be ideal for a heat pump.
Your Home's Insulation Makes a Difference
A modern, well-insulated property may remain warm for hours after the heating switches off.
An older house with limited insulation and noticeable draughts could lose that warmth far more quickly.
Rather than following one universal rule, start by observing how quickly your own home cools down.
Try adjusting your heating schedule and compare energy use under similar conditions. Over time, you'll develop a clearer understanding of what works best for your particular property.
Are Electric Blankets Cheaper Than Electric Heaters?
One of the biggest differences in winter heating costs comes from understanding the distinction between warming an entire room and keeping one person comfortable.
An ordinary electric heater warms the surrounding air.
An electric throw or heated blanket concentrates a much smaller amount of energy close to your body.
That means the amount of electricity required can be dramatically lower.
Electric Throw Running Costs
Consider a heated throw rated at 100 watts, or 0.1 kilowatts.
Using the same illustrative electricity price of 26p per kilowatt-hour, its maximum continuous running cost would be just 2.6p per hour.
| Heating Method | Power Consumption | Cost Per Hour |
|---|---|---|
| Electric heated throw | 100W | 2.6p |
| Small electric heater | 500W | 13p |
| Portable electric heater | 1,000W | 26p |
| Large electric heater | 2,000W | 52p |
Illustrative costs at 26p/kWh, assuming continuous operation at the stated power. Thermostats and heat settings can reduce actual consumption.
For someone sitting on the sofa during the evening, a heated throw may provide additional comfort for a fraction of the electricity used by a portable room heater.
However, a heated throw doesn't warm the room itself and shouldn't be treated as a complete replacement for adequate household heating.
Other Ways to Stay Comfortable Without Increasing the Heating
The same principle applies to ordinary clothing and bedding.
Warm socks, comfortable additional layers and a blanket can make a room feel more pleasant without requiring a higher thermostat setting.
The objective is to make efficient use of heating while maintaining a healthy, comfortable indoor environment.
For many households, combining reasonable room heating with personal warmth is more practical than relying on either approach alone.
Does Turning Down Your Boiler Temperature Save Money?
If your home has a modern condensing gas boiler, one setting worth understanding is the central heating flow temperature.
This controls the temperature of the water your boiler sends around the radiators.
It is separate from your room thermostat, which controls the desired temperature of the room itself.
For example, your room thermostat might be set to 20°C while the boiler sends considerably hotter water through the radiator system.
How Boiler Flow Temperature Affects Efficiency
Condensing boilers can operate more efficiently when the returning water temperature is sufficiently low to support condensation and recover additional heat from the exhaust gases.
Reducing the central heating flow temperature can help achieve this under suitable conditions.
However, cooler radiator water also means the radiators may release heat more slowly, particularly during very cold weather.
The aim is to find an appropriate setting that keeps the home comfortable while allowing the boiler to operate efficiently.
Combi Boilers and Hot Water Cylinders
With many combi boilers, the radiator flow temperature can be adjusted independently from the domestic hot water setting.
Systems using a hot water cylinder are different, because boiler operation may also be involved in heating stored domestic hot water.
Stored hot water has its own temperature requirements, so settings should not be changed indiscriminately.
Before changing boiler settings: Check the manufacturer's instructions and identify whether you have a combi boiler, a system boiler or another arrangement.
If you're uncertain which control adjusts central heating flow temperature, seek appropriate advice before making changes.
The potential saving depends on your boiler, radiator sizes, insulation and existing settings.
It's another area where understanding equipment you already own may produce worthwhile savings without buying anything new.
How Do You Keep Bedrooms Warm Without Wasting Energy?
Bedrooms have slightly different heating requirements from living rooms.
Many people prefer a cooler bedroom when sleeping, but allowing the room to become excessively cold can create problems with comfort, condensation and damp.
This can be particularly noticeable in older properties with poorly insulated external walls.
Use Lower Radiator Settings Where Appropriate
If your bedroom has a thermostatic radiator valve, you may be able to maintain a lower temperature than the living room while still providing background warmth when the heating operates.
You could also arrange your heating schedule so the bedroom becomes comfortably warm before bedtime without maintaining the same temperature throughout the day.
Improve Air Circulation Around Furniture
Large wardrobes and other furniture positioned directly against cold external walls can restrict airflow.
Where possible, leaving a small gap allows air to circulate behind the furniture and may help reduce persistent condensation.
Likewise, avoid blocking radiators with furniture or allowing heavy curtains to cover them.
Closing bedroom curtains after sunset can also help reduce heat loss through the windows.
These are small adjustments, but together they can improve bedroom comfort without requiring substantial additional heating.
How Do You Prevent Condensation and Mould in Winter?
Keeping warmth inside your home is important, but so is controlling moisture.
Everyday activities such as cooking, showering and drying clothes release water vapour into the air.
When warm, humid air meets a sufficiently cold surface, condensation can form.
Windows, outside walls and areas behind large furniture are common places for this to happen.
Persistent moisture can eventually encourage mould growth, especially in properties where rooms remain cold for long periods.
Reduce Moisture Without Wasting Unnecessary Heat
Simple changes to everyday routines can help manage humidity.
- Put lids on pans when cooking to reduce the amount of steam entering the room.
- Use kitchen and bathroom extractor fans where fitted.
- Maintain appropriate ventilation rather than sealing purpose-built air vents.
- Avoid leaving wet fabrics against cold windows or external walls.
- Allow air to circulate around furniture positioned near colder walls.
- Maintain reasonable background warmth in rooms that are prone to condensation.
Good ventilation and effective draught-proofing are compatible.
Draught-proofing addresses unwanted air leakage through gaps and damaged seals. Ventilation provides a controlled way for fresh air to enter and moisture to escape.
Both contribute to a more comfortable home.
Remember: A room that feels cold and damp can remain uncomfortable even when the heating is running.
Controlling moisture, improving insulation and maintaining appropriate heating can work together to improve comfort and reduce problems with condensation.
What Are the Cheapest Ways to Keep Your Home Warm?
Once you've looked at the different ways heat enters and escapes from your home, it's much easier to identify the improvements likely to provide the greatest benefit.
For most households, the sensible approach is to begin with changes that cost nothing and then consider inexpensive purchases where they solve a specific problem.
Start With These Practical Improvements
- Check doors and windows: Identify and reduce unwanted draughts before increasing your heating.
- Use curtains effectively: Let sunshine enter during the day and close curtains after sunset.
- Manage individual rooms: Adjust radiator valves to suit how each room is used.
- Review your thermostat: Find a comfortable setting without heating rooms unnecessarily.
- Compare heating costs: Work out the electricity consumption of portable heaters before relying on them.
- Consider personal warmth: Heated throws and ordinary blankets can provide extra comfort at relatively low cost.
- Understand your boiler: Check whether your central heating flow temperature can be adjusted appropriately.
- Control moisture: Maintain suitable ventilation and prevent persistent condensation.
- Check your actual energy usage: Compare consumption after making individual improvements.
You don't need to tackle every improvement immediately.
Start with the rooms you use most, identify where warmth is being lost and make one change at a time.
The money saved through better heating controls, fewer draughts and more sensible energy use can add up over an entire winter.
How Can You Prepare Your Home for Winter on a Budget?
Winter preparedness is about more than keeping emergency supplies in a cupboard.
It's also about making your home more comfortable, reducing unnecessary expenses and understanding how your household will manage during colder weather.
Being prepared doesn't require expensive specialist equipment. Many of the improvements covered in this guide involve making better use of things you already own.

Final Thoughts: Staying Warm Without Wasting Money
Heating your home for less isn't about finding one magical appliance or forcing yourself to live in uncomfortable conditions.
It's about using the warmth you're already paying for more effectively.
Reducing draughts, improving curtains, adjusting heating controls and choosing appropriate equipment can all make a difference.
Some changes may produce noticeable savings, while others will mainly improve comfort. The results will depend on your property, heating system and existing energy usage.
Start with simple improvements, monitor what changes and build on what works.
Over time, small improvements can help create a home that's warmer, more comfortable and less expensive to run through the winter months.
