Overview
- Guides published today highlight draught excluders from about £5, with experts estimating around £65 in annual savings from blocking gaps around doors and windows.
- Reflective radiator panels, starting near £7, are promoted as a quick DIY upgrade to redirect warmth back into rooms rather than heating external walls.
- Window insulation film kits priced at roughly £10–£20 offer a removable, renter‑friendly layer that helps retain heat and reduce draughts on single‑glazed or underperforming windows.
- For homes with fireplaces, chimney balloons costing £20–£30 are advised to plug flues and can save an estimated 10–15% on heating costs.
- Upgrading loft insulation to around 270mm typically costs about £900 and is cited to save £200–£300 a year, with a payback in roughly three to four years; sealing loft hatches and small gaps with low‑cost materials further reduces heat loss.
