How to Choose

  • Light blocking vs. insulation: If you need total darkness, go for blackout curtains (100% block). If your main issue is cold, thermal curtains with moderate light blocking may be enough.
  • Window size and shape: Custom curtains like Hillarys fit odd windows, while standard sizes from Dunelm or Argos suit rectangle windows.
  • Budget: Entry-level options from Argos or IKEA work for short-term fixes, while investing in Dunelm or John Lewis provides longevity.
  • Noise reduction: Look for acoustic-lined options like Silentnight if street noise disturbs your sleep.
  • Care and maintenance: Machine-washable curtains (e.g., Dunelm, Argos) are easier to clean than dry-clean-only luxury ones.
  • Aesthetic preference: If style matters, John Lewis or The White Company offer more refined fabrics and colours.
