This paper provides advice and guidance for councillors and chief officers to help them respond to the Care Act 2014 by working together with partners in their local communities to develop volunteering and social action. The paper identifies Care Act duties placed on local government and partner organisation, which are to promote wellbeing; prevent reduce or delay needs by building on the resources of the local community; the provision of information and advice; and shaping a diverse and sustainable local market of providers for care and support. It then highlights the role volunteering can play in helping to fulfil these duties; why the VCSE sector is a useful partner for local authorities seeking to deliver their Care Act responsibilities; and identifies Care Act duties where volunteers can make a contribution. It also identifies shared features of initiatives which are effective building community capacity and promoting voluntary action. These are that they are co-produced, respond to local context, human in scale, strength-based; build in learning; build in sustainability; and adaptive, able to learn from their experience. It concludes with the challenges that need to be addressed to make the most of community capacity and build services which are ‘prevention-focused’. These are to provide community leadership and strategic direction; replicate and scale up good practice; prioritisation versus competing demands; commissioning practice; facilitate choice and control through micro-commissioning; supplement not displace paid work; and measure the impact of volunteering.
