How to Choose

• Light blockage level: Look for ‘100% blackout’ or ‘thermal’ labels. Roller blinds usually offer the best seal. Roman blinds may let light in at the edges.
• Window size and fit: Measure your window recess first. Some brands offer made-to-measure, others only standard widths. A poor fit ruins blackout effect.
• Installation method: If you can’t drill, choose clip-on or tension rod blinds. Drill-in brackets are more secure but damage walls.
• Material and durability: Thicker fabrics last longer and block more light. Check if the lining is removable for cleaning.
• Price vs. features: Under £50, you can get good blackout but not smart features. Decide if thermal or cordless options are worth extra.
