Supporting the performing arts to achieve greater equality, diversity and inclusion

About Tonic

Tonic is an independent organisation and charity that works with the performing arts and other cultural organisations to achieve greater equality, diversity and inclusion. Established in 2011, Tonic is now a leading agent for change, with a proven track record of enabling theatre, opera, music and dance companies to deliver lasting, positive results.

We do this in a number of ways including training, consultancy and workshops, led by our expert team of trainers and facilitators, and through writing and research, compiling comprehensive resources for the creative sector to use.

Our approach involves analysing the underlying principles of our industry – our working methods, decision-making processes and organisational structures – and showing how these may create barriers to equality, diversity and inclusion. Once these are identified, we can support you and your organisation to move forward and create tangible change.

“The work the National Theatre have been doing with Tonic is enhancing our understanding with both nuance and vision. In fact, Tonic has become increasingly pivotal in helping the entire industry, through organisations and individuals, raise its game.”
Rufus Norris, Director, National Theatre

Who we work with

We work with a range of leading organisations, big and small, in both subsidised and commercial sectors, from around the country and overseas too. Since 2011, we have worked with hundreds of organisations, and thousands of people, from members of youth theatre groups, drama schools, training institutions and the community arts sector though to renowned drama, opera and dance companies. We have now established a network of best practice in key organisations nationwide, and the UK performing arts industry is, as a result, more rigorous in its decision-making.

Beyond the performing arts, Tonic has experience delivering training in the wider cultural and creative sectors – for film companies, museums, galleries, heritage organisations and educational institutions. We’d be happy to discuss how we can adapt our training to suit your requirements.

“What’s great about Tonic is that it’s not superficial. The work it’s doing is subtle, nuanced and in depth and that’s what I really appreciate about Tonic.”
Indhu Rubasingham, Artistic Director, Kiln Theatre
