How to stop hot and cold spots from ruining your evening

Evenings should bring calm, not complaints about one room feeling like a sauna and another making you shiver. Especially the last few evenings, when it’s hit -9 here in the North West, I’ve found myself wearing my Oodie (warmest thing to ever be designed, by the way) AND a blanket just to stop my hands and feet resembling blocks of ice.

Our house is not the warmest. Let me rephrase that…

Our house is draughty as hell. Thanks to an old and warped front door, big French doors, a breezy letterbox and the cat flap, the heat leaves our house as fast as it’s created.

 

But it doesn’t have to be this way. Whether you’re based in chilly northern Cheshire like me or the warmer climes of Brighton (where you may need Brighton air conditioning in the summer to prevent major overheating), I’m going to chat through some of the solutions to your cold-spot problems.

 

Step 1: Find the source of discomfort

Hot and cold spots rarely appear by accident, so there is almost always a clear cause.

Poor insulation, blocked vents, or an old heating system that is operating beyond its original design can all cause uneven temperatures.

So what should you check? First, look for where draughts can get in. The main culprits are air bricks, windows, doors, letterboxes, cat flaps, chimneys, broken seals, floorboards. All of these things basically let air in, which isn’t a problem in the summer, but can create cold spots all over your house in the winter.

 

Step 2: Learn how to control the airflow

I know, I just said draughts were bad. But warm and cold air are constantly trying to move around your home, but when that airflow is blocked or uneven, temperatures quickly fall out of balance.

Something as simple as a sofa, bookshelf or heavy curtains covering a vent can stop air in its tracks, leaving one room roasting while the next feels freezing. Even partially blocked vents can throw the whole system off, because airflow works as a network. Restrict it in one place and you’ll feel the knock-on effect elsewhere.

This is where small adjustments make a big difference. Make sure vents are clear, then use adjustable registers and dampers to fine-tune how much air each room receives. Opening or closing them slightly helps redirect airflow to spaces that need more warmth or cooling, smoothing out temperature swings across the house.

Ceiling fans can help too, and not just in summer. In winter, setting them to run clockwise at a low speed gently pushes warm air back down from the ceiling, preventing it from pooling overhead and leaving lower areas feeling cold.

 

Step 3: Consider the upgrades you’d like to make

Nothing lasts forever, not even that reliable boiler or the old set of radiators from decades past.

Technology moves on fast, and when it comes to home comfort, that’s very good news. There are tons of ways you can make your home warmer without making a big impact on your energy bills. You could invest in a more efficient boiler, upgrade your radiators, install underfloor heating, and so much more.

Modern programmable thermostats can make a real difference, learning how you use your home and adjusting heating and cooling cycles to match, so you’re not left with an oven-hot kitchen while the lounge feels like a fridge.

Zoned systems take things a step further by letting you control the temperature room by room. That means no single space hogs all the energy, and no more nightly debates about who’s too hot and who’s reaching for a jumper. Just don’t be tempted by cheap gadgets promising instant miracles. You’re far better off investing in systems that actually deliver. They’ll give you a better night’s sleep, steadier temperatures, and a much quieter evening all round.

 

Step 4: Seal those draughty areas

Tiny gaps around doors and windows seem insignificant until the draught proves otherwise at dusk, with every gust outside announcing itself inside too clearly for comfort.

Weatherstripping immediately makes a significant impact. Weatherstripping is a rubber or foam material that can be used to seal gaps around doors and windows to stop noise, draughts, rain or even dust from coming into the house.

You don’t need any major skillset to install them, and they’re very cost effective, too.

Cavity wall insulation is another fabulous investment, and prevents major heat loss from the walls of your home (yep, not all heat is lost through the roof, as many people seem to think).

Finally, modern double glazing puts an end to window woes once and for all by locking temperature-controlled air safely indoors regardless of the UK’s unpredictable moods after sunset.

 

Step 5: Make some other small changes

Balance and bleed radiators

Uneven heating is often down to radiators not pulling their weight. Trapped air, sludge, or poor balancing can mean some rooms heat up fast while others never quite get there. Bleeding radiators and having the system balanced helps distribute heat more evenly across the house, especially in older properties.

Add radiator reflector foil

Not glamorous, but very effective, especially on external walls. Reflective foil behind radiators pushes heat back into the room instead of letting it disappear straight through the wall, which can noticeably reduce cold patches near windows.

Layer soft furnishings strategically

Rugs, thermal curtains, and lined blinds don’t just make a space feel cosy, but they reduce heat loss through floors and windows, which is where cold spots love to form. This is especially useful in older homes with suspended timber floors.

Address humidity levels

Cold, damp air feels colder than dry air. Dehumidifiers or better ventilation can make rooms feel warmer without turning the thermostat up, particularly in bedrooms and north-facing spaces. I wouldn’t be without our dehumidifier now. It collects around 20L of water in a few days, which would otherwise be stuck and recirculating around our house!

 

If you’re absolutely fed up with cold spots in your house, like me, then I hope this guide has helped somewhat. I’ve tried to include actionable changes that you can do now to improve the cold/hot spots in your house and make your evenings somewhat more comfortable.

Getting on top of temperature ups and downs saves your sanity as much as your energy bills, bringing calm back to spaces that were once ruled by thermostat arguments and blanket-sharing negotiations. They will be no more.
