Overview
- Heating specialists at Plumbworld recommend hanging heavy curtains across internal doorways and behind front doors to trap warmth.
- Salford University’s Energy House tests indicate heavy curtains can reduce glazing heat loss by roughly one-third to two-fifths and raise room temperatures by about 1–2°C.
- This measure has no running cost and suits renters because it can be fitted without drilling, for example with a tension rod.
- Ofgem estimates a typical household bill at about £1,755 a year for October to December 2025, while UK searches for “help with energy costs” have risen around 80%.
- About 9.6 million UK households are in inadequately insulated homes, underscoring the value of simple draught-proofing such as portières and floor-level draught excluders.
