Yardley London has been a purveyor of quality soap since the 17th century when the Yardley family paid king Charles I to grant them a concession to manufacture soap for London. All of our soaps are traditionally triple milled which means theyâre processed three times over to reduce excess water making the soap very hard but long lasting with a rich creamy lather. The soaps are scented with our beautiful fragrances at the final stage of milling to enhance the longevity of their scent.
