The National Lottery Community Fund is the largest community funder in the UK, distributing over £500 million per year to projects with a social mission across the UK. In 2016, The National Lottery Community Fund commissioned TSIP to help organise a Roundtable for supporting stronger, more diverse civil society leadership. TSIP drew on international best practice and consulted leaders and stakeholders across the UK social sector. Between 2017-2018 TSIP worked with The National Lottery Community Fund and UnLtd to develop a new social leadership programme for those with ‘lived experience’: connecting those with lived experience to those with power in the social sector to build bridges between social purpose organisations and the communities they purport to serve, and promote the value of lived experience in leadership. We are currently acting as expert advisers, working on outcomes frameworks for The National Lottery Community Fund’s approach to measuring the impact of their funding for people living with disabilities in developing countries.
