The other half of being weather-ready
Britain's real weather emergency isn't the heatwave — it's the freeze. Our homes are among the draughtiest in western Europe, and cold homes are linked to thousands of excess winter deaths each year. The good news: most of the fix costs less than one month's heating bill.
Why it matters
These figures are indicative — for current statistics see the Office for National Statistics and GOV.UK fuel poverty statistics.
The plan
The golden rule: heat the person, then the room, then the house. Work down this list and stop when you're warm.
The single highest-impact cheap fix. Brush strips, letterbox flaps and a classic sausage-dog draught excluder.
Cost: £5–£20 · pays for itself in weeksWindows lose heat fastest. Liners hook onto your existing curtains; close them the moment the light fades.
Cost: ~£35 a pair · bonus: doubles as summer blackout shadeTemporary secondary glazing: clear film, tape, hairdryer. Fully removable — landlord-proof.
Cost: ~£13 per multi-window kitA low-energy heated throw warms you for pennies per evening versus pounds for whole-house heating.
Cost: ~£50 once · pennies per eveningCold at the top means trapped air. A radiator key costs pence. And a sofa parked against a radiator is heating the sofa.
Cost: under £1Most fans have a winter switch — clockwise on low pushes risen warm air back down. The summer fan earns its keep twice.
Cost: freeColder, better-sealed homes can grow condensation. Ventilate briefly after showers and cooking; a small dehumidifier protects walls and lungs alike.
