Silentnight duvets are made under licence by Comfy Quilts Limited. They have given their response to your question below.
"As there is no legal requirement for standard (household) duvets to comply with the flame retardant standards of BS7175 - our duvets are not manufactured to this standard.
They are however tested & comply with the Tog Testing requirements of BS5335".
