How Much Can Blackout Curtains Save on Energy Bills?
With rising energy costs and the ongoing need to make our homes more efficient, blackout curtains have become more than just a stylish interior upgrade, they’re a smart investment. Particularly here in the UK, where older homes and unpredictable weather are common, blackout or thermal-lined curtains can make a real difference to comfort and cost.
So just how much can you save by adding blackout or thermal linings to your made to measure curtains? Let’s take a look.
The Energy-Saving Power of Blackout Curtains
According to Free Price Compare, heat loss through windows accounts for around 25–30% of your home’s overall energy loss. Blackout and thermal curtains can act as an additional layer of insulation, keeping the warmth in during colder months and helping regulate indoor temperature throughout the year.
It’s not just a small difference. Homeowners who invest in well-fitted thermal-lined curtains could save:
- £80–£150 per year on heating bills in an average home
- Up to £291 per year in homes with older windows or poor insulation (Country Living)
For those living in smaller spaces, like a two-bedroom flat, even modest updates have had a notable impact, one household reported annual savings of £150 after installing thermal curtains (The Sun).
How Do Blackout Curtains Work?
Blackout curtains aren’t just for blocking early sunlight. They’re made with dense materials and special linings that trap warm air inside and reduce cold drafts. According to The Mill Shop, these linings help maintain a consistent indoor temperature, which is key to lowering your energy usage.
They’re especially effective when:
- Fitted properly – Make sure they cover the entire window and ideally extend past the sill or down to the floor.
- Used at the right time – Closing your curtains at dusk can significantly reduce heat loss (Express)
- Sealed at the edges – Using Velcro or magnetic strips along the edges helps to prevent heat from escaping around the sides (Good Housekeeping)
