Widely regarded as one of Britain’s freshest and most trusted authorities on etiquette, William’s ‘day job’ is as director of The English Manner, a leading UK etiquette training institute, where he advises individuals, organisations, and films on correct form and good manners.

He is also known for appearances on television, radio and most notably his podcast Help I Sexted My Boss, which regularly leads the Apple Podcasts and Spotify charts. In 2021, he also launched Keeping Up Appearances: The Luxury Podcast, which begins its fifth series later in April 2024.

William is the author of four books, including the Sunday Times bestseller Help I S*xted My Boss (2023).

William was the on-set etiquette advisor for the Amazon Prime Video film Red, White and Royal Blue and, for some reason, holds two Guinness World Records for etiquette, set in 2012 and 2019.
