Supporting the arts and cultural sector to achieve greater equality, diversity and inclusion

About Tonic

Tonic is a national independent organisation and charity that works with the arts and other cultural organisations to achieve greater equality, diversity and inclusion. Initially established in the theatre industry, the success of Tonic’s approach saw demand for our work extend into other areas of the performing arts, particularly dance and opera. Today we continue to work extensively in these fields whilst also increasingly expanding into a range of other areas including music, museums, television drama and the wider cultural sector. 

Tonic is now a leading agent for change, with a proven track record of enabling organisations in the arts and cultural sector to deliver lasting, positive results.

We do this in a number of ways including bespoke, affordable 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 to change involves analysing the underlying principles of an organisation – the 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.

“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 right across the arts and cultural ecosystem, with venues, producers, commissioners, festivals, training and educational institutions, businesses in the arts ‘supply chain’, professional membership bodies, networks, and amateur and community groups. We have developed multi-year relationships with some of the biggest arts organisations in the country (such as the National Theatre, Royal Opera House, Royal Shakespeare Company, Sadler’s Wells), as well as working with micro-companies operating on a hyper-local level and with organisations of all shapes and sizes in between. Through our books, online resources and industry-facing events, freelancers and other individuals can engage in our work too. 

“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.”
