The social enterprise sector is growing. Recent government estimates suggest there are 70,000 social enterprises in the UK, employing around a million people. The sector’s contribution to the economy has been valued at over £24 billion. The UK is a pioneer when it comes to social enterprise and the social investment that helps finance it, attracting the interest of international practitioners and policymakers alike. The social enterprise sector’s economic and social contribution is also increasingly recognised by government, business and individuals alike – from the Treasury’s announcement of a tax incentive for investment into social enterprise to the increased procurement of social enterprise in private sector supply chains.
