Yardley holds 2 Royal Warrants.
On the Yardley website it says:-
“True to our heritage, we feel that it is important that as many of our products as possible are sourced in the UK and as of 2012 a large proportion (90%) continue to be manufactured in the UK with the majority of remaining products being made in the EU.”
Also, established in 1770 (as a chemist), Woods of Windsor now sells soaps, fragrances, bath products, hand cream and the like. I think there products are (at least mostly) made in England. They have a shop near Windsor Castle, in Windsor, England. They also sell Yardley products in their shop.
As far as I can work out (and it is by no means clear!) Yardley London and Woods of Windsor are owned by the Indian company Wipro. Yardley London is run as a disctinct entity, based at the Woods of Windsor shop in Windsor. However, another Indian company Lornamead owns Yardley in the Americas, Germany and Austria (they have a separate website – http://www.yardleylondon.com). There is no indication on their website of where Yardley Americas, Germany and Austria make their products.
