Britannia works with Sir Alistair Spalding CBE and the Board of Trustees to define and deliver a long-term strategy for growth. Under their leadership, Sadler’s Wells has become a world leading arts organisation. With four London theatres, a digital platform and productions that tour up and down the country and globally, Sadler’s Wells presents a highly ambitious programme of cutting-edge dance as well as a celebrated Learning & Engagement programme with activities taking place nationwide.

Britannia led on the planning and development of Sadler’s Wells East, a brand-new powerhouse for dance in the Queen Elizabeth Olympic Park which opened in February 2025. Sadler’s Wells East is home to a 550-seat flexible theatre, two educational facilities: the UK’s first hip hop theatre school, Academy Breakin’ Convention and the Rose Choreographic School, six state-of-the-art dance studios, and a large open foyer with a public performance space, The Dance Floor, for free workshops and dance classes.

She has worked at Sadler’s Wells since 2010 and previously led operational teams at Southbank Centre, the Barbican, Royal Albert Hall and ENO.

In late 2024, Britannia was appointed as a member of the Arts Council London Area Council – offering her expertise alongside London borough councillors and the Deputy Mayor for Culture and the Creative Industries, and in June 2025 was appointed to the Board of Scottish Ballet.
