Winter energy prices make every wasted degree of heat feel expensive, but cutting bills does not have to mean living in a freezing home. I have pulled together five quick, practical fixes that rely on simple tools and widely reported expert advice to keep more warmth indoors. Used together, these small changes can trim winter heating costs while making rooms feel noticeably more comfortable.
1) Seal Drafts Around Windows and Doors
Sealing drafts around windows and doors is one of the five simple actions that recent UK coverage says can help cut annual heating bills by about £200 when combined with other steps. Reporting on how to save money on central heating stresses checking for gaps where even the slightest draught can creep in and replacing or adding seals. I would start with obvious problem spots, such as letterboxes, keyholes and the edges of older timber frames, where worn rubber strips or cracked sealant often let warm air leak straight outside.
Once those leaks are blocked, radiators and boilers do not have to work as hard to maintain the same temperature, which is why experts group draught-proofing with other efficiency tweaks in that £200 saving estimate. Simple self-adhesive foam strips, brush-style draught excluders and silicone sealant are inexpensive and can usually be fitted in an evening. For renters, removable fabric draught stoppers and temporary film around leaky frames avoid damaging fixtures. The broader trend in the reporting is clear: households that systematically plug these gaps tend to see lower bills and fewer cold spots.
2) Apply Tin Foil Behind Radiators
Applying tin foil behind radiators is a classic DIY shortcut that has resurfaced in late 2025 coverage as a way to reflect heat back into the room instead of letting it soak into external walls. A guide to DIY expert hacks explains how a simple sheet of foil, or purpose-made reflective panels, can be fixed behind radiators to bounce warmth into the living space. I would focus this trick on radiators mounted on outside walls, where heat loss is greatest and the reflective surface can make the most difference.
Separate reporting on a simple effective foil trick even links reflective backing to potential savings, citing a wider package of heating fixes that can reportedly slash costs by as much as £2,400 in extreme cases. That figure reflects a whole bundle of measures, not foil alone, but it underlines how wasted heat adds up. Social clips such as the “Heat Your Home Efficiently” and “Tin Foil Hacks” video, which urges viewers to “Discover” quick “DIY” solutions, show how mainstream this approach has become for people trying to tame winter bills.
3) Lower Your Thermostat by 1 Degree
Lowering your thermostat by just 1 degree is one of the simplest ways to cut winter heating costs without major lifestyle changes. Guidance on how to cut home heating costs this winter highlights small thermostat adjustments as a core efficiency step, because heating systems use less fuel every time the target temperature drops. I would treat 1 degree as a starting point, then experiment with slightly cooler settings in hallways or bedrooms where heavy duvets and blankets can take up the slack.
Energy specialists consistently point out that most households adapt quickly to a modest change, especially if they warm the person rather than the whole house with layers and hot water bottles. Programmable or smart thermostats make this even easier by automatically reducing temperatures overnight or when nobody is home. The broader implication is that, when combined with draught-proofing and radiator tweaks, a single degree can be the difference between a painful bill and one that feels manageable across a long winter.
4) Bleed Radiators to Remove Air
Bleeding radiators to remove trapped air is another of the five expert-backed steps linked to that £200 reduction in annual heating costs. Coverage explaining why heating bills will be lower if you do 5 easy things describes how air pockets stop hot water circulating properly, leaving radiators cold at the top and forcing boilers to run longer. I would check each radiator at the start of the season, using a simple key to release air until water flows in a steady stream.
Once radiators heat evenly, rooms warm up faster and thermostats can switch off sooner, which directly cuts gas or electricity use. This step is especially important in multi-storey homes, where upper-floor radiators often collect air and underperform. Combined with the earlier draught sealing and foil tricks, efficient radiators help ensure that every unit of heat you pay for ends up in the living space, not locked in pipework or wasted in cold corners.
5) Use Thermal Curtains or Blinds
Using thermal curtains or blinds helps trap warm air inside and block cold draughts around glass, which is why window treatments feature prominently in expert advice on winter efficiency. Analysis of DIY expert’s simple hacks and broader cost-cutting guides shows that thick, well-fitted curtains can act almost like an extra layer of insulation when closed at night. I would prioritise large single-glazed or north-facing windows, where heat loss is most severe and the pay-off from better coverings is quickest.
Consumer-focused guidance on All bubble-wrap window tricks and similar low-cost ideas reinforces the same principle, turning bare panes into barriers against cold air. Ready-made thermal curtains, lined Roman blinds or even layered roller blinds can all reduce the chill that radiates from glass on frosty evenings. For households facing rising tariffs, these fabric fixes are a relatively affordable way to support the other four measures, keeping rooms warmer for longer so the heating can switch off earlier without sacrificing comfort.
