From the FAQ on their site:
Some sarcasm:
Yes, we are excluding tallow in our products because it would be unethical to kill cattle just for the fat around the kidney and throw the rest of the carcass and meat away which is of no use for anybody.
Do any of your products contain any animal by-products? Some of our fragrance and toiletries range do contain animal by-products. However, we are working to eradicate this in exchange for vegetarian alternatives.
...
Do you use badger hair in our shaving brushes? Yes we do as this is by far the most superior fibre for applying shaving lubricants. However, as a part of gaining our warrant status we have proven to the Royal Warrant Holders Association (who re-issued our warrant in 2006), that our shaving brush supplier only purchases from ethical badger farms in a part of the world where badgers are not endangered and are in fact primarily farmed for their meat.
