Heat the human, not the home. That is the single most effective mindset shift for staying warm this winter without a bigger energy bill, and it is the opposite of the instinctive reaction to a cold house, which is turning the thermostat up.
Running gas central heating for a typical UK 3-bedroom home costs somewhere around 65p to £1.10 an hour while it is actively firing, which adds up to roughly £4-£7 a day for 6-8 hours of heating.
Warming yourself directly costs a fraction of warming an entire house.
Where are you actually losing warmth?
The right fix depends on which of these you recognise. Find your row, then jump to that section.

Get the free wins first
None of these cost anything, and together they make a noticeable difference before you switch anything on.
Use your curtains properly
Open them during the day, even on a grey day, since sunlight through glass still adds genuine warmth to a room. Close them the moment the sun goes down, since this is when a room starts losing heat fastest through the glass.
This costs nothing and takes seconds.
Use the oven's leftover heat
After cooking, switch the oven off and leave the door open. The residual heat warms the kitchen for free rather than escaping unused once the oven cools down on its own.
Check what's blocking your radiators
Furniture, curtains, or clothes drying directly in front of a radiator block the warm air from actually reaching the room, which means the radiator works harder for less benefit.
A good rule of thumb is to keep at least 30cm clear in front of any radiator, whether that’s furniture, curtains, or a clothes airer, so heat can circulate properly into the room rather than getting trapped and wasted right at the source.
Heat yourself, not just the room
Warm feet make a genuinely disproportionate difference to how warm you feel overall, since a lot of body heat is lost through the feet. Thick socks and proper slippers are one of the simplest, cheapest wins available, and if you’re shopping for a pair, our gifts for someone who’s always cold guide covers genuinely well-reviewed options for both.
A handful of cheap electrical extras genuinely earn their keep here too: heated gloves, USB hand warmers, and heated insoles can cost as little as 1p an hour to run, and a microwave wheat bag or a hot water bottle costs only a few pence per use. Compared to the 65p-£1.10 an hour it costs to run central heating for an entire house, warming just yourself directly is a genuinely different order of cost. None of these need to heat a whole room to make a real difference to how warm you actually feel.
Add direct, low-cost heat where you sit
An electric blanket or a heated throw is one of the most cost-effective ways to stay genuinely warm without heating a whole room, since it only needs to warm the small space immediately around you rather than an entire house. Our best electric blankets UK guide covers underblankets and throws by price and feature.
For a specific, cold room rather than warming yourself directly, a small electric heater used for an hour or two in the evening is often cheaper than running central heating for the whole house over the same period. Our best electric heaters UK guide covers picks suited to this kind of targeted use.
Get the basic room temperatures right
If you use a heating timer, setting it to come on shortly before you wake up or get home is generally more effective and cheaper than leaving it off and turning the thermostat up higher once you’re already cold, since a home takes time to properly warm through regardless of how high the setting goes.
The one caveat worth taking seriously: don’t over-seal your home
Draught-proofing genuinely reduces heat loss and is one of the better investments for a cold home, but it’s worth doing carefully rather than sealing every gap indiscriminately. A completely sealed room with no ventilation traps moisture from breathing, cooking, and general living, which is exactly the condition that leads to condensation and mould.
If you’re draught-proofing seriously, it’s worth reading our guide to why your house might be so damp in winter alongside it, since the two problems are genuinely connected. The balance that works best is reducing draughts around doors and windows specifically, while keeping some basic ventilation, an extractor fan, a window cracked briefly each day, rather than sealing a room completely airtight. Our full guide to draught proofing windows and doors covers the specifics.
The quick checklist
The whole guide, in the order worth doing it.
- Open curtains during the day, close them the moment it gets dark
- Leave the oven door open after cooking to release residual heat
- Keep at least 30cm clear in front of radiators so heat can circulate
- Layer properly: thin base, mid layer, outer layer, rather than one thick jumper
- Warm your feet specifically, with proper slippers or thick socks
- Use cheap personal heating: heated gloves, hand warmers, a hot water bottle
- Never combine an electric blanket and a hot water bottle in the same bed
- Keep the room you're in at 18-21°C, rest of the house at a minimum of 16°C
Staying warm without heating: your questions answered
It means focusing on warming yourself directly, through clothing, layering, and small personal heating items like heated gloves or a hot water bottle, rather than heating an entire house to make one person comfortable. Since these items only need to warm a small area immediately around your body, they typically cost a fraction of what running central heating for the same comfort would cost, which is currently around 65p to £1.10 an hour for a typical UK 3-bedroom home.
No, this combination should be avoided. Using an electric blanket and a hot water bottle in the same bed carries a genuine electrocution risk if the hot water bottle leaks and the electric blanket gets wet. Use one or the other, not both together in the same spot.
General guidance suggests keeping your main living space at around 18 to 21 degrees Celsius during the day, with the rest of the house at a minimum of 16 degrees. Bedrooms are generally recommended to stay above 18 degrees overnight. Heating only the rooms you’re actually using, rather than the whole house evenly, is one of the simplest ways to keep costs down without feeling genuinely cold.
It can, if done without maintaining basic ventilation. Sealing every gap in a room stops warm air escaping, but it also traps the moisture produced by breathing, cooking, and daily living, which is exactly the condition that leads to condensation and mould. The safest approach is to reduce draughts around doors and windows specifically, while still allowing some ventilation, such as briefly opening a window each day or keeping an extractor fan in use.
For most modern, well-insulated UK homes, turning the heating on only when needed, using a timer set to come on shortly before you wake up or get home, tends to be cheaper than leaving it on low continuously throughout the day. Homes generally lose heat faster than most people expect once the heating switches off, so there is rarely a meaningful saving in keeping it running constantly at a low level.
Yes, genuinely. Windows are one of the biggest sources of heat loss in most homes, and closing curtains as soon as it gets dark creates an extra layer of insulation between the room and the cold glass. Opening curtains during the day, even when it’s overcast, also lets in some free warmth from sunlight, which is worth doing before closing them again once the sun sets.
For a typical UK 3-bedroom home in 2026, running gas central heating costs roughly 65p to £1.10 an hour while the boiler is actively firing, which works out to around £4 to £7 a day for 6 to 8 hours of heating. This is why heating only the rooms you’re using, or warming yourself directly rather than the whole house, can make such a meaningful difference to your energy bill.
