Book excerpt: The Department for Communities and Local Government does not have a good enough understanding of the impact of funding cuts, either on local authorities' finances or on services. It is unclear whether the Department is exercising a cross government leadership role with respect to local government. It relies on data on spending and has little information on service levels, service quality, and financial sustainability. HM Treasury should better support the Department by ensuring compliance with its requests for information at future spending reviews. While the Department has identified that local authorities will need to change the way they deliver services to remain financially sustainable, it is unclear if it is providing sufficient leadership to ensure they can implement service transformation programmes successfully. Furthermore, if funding reductions were to continue following the next spending review, we question whether the Department would be in a position to provide assurance that all local authorities could maintain the full range of their statutory services. Overall, as pressure from cuts grows, so do the risks to local authorities' finances and their provision of services. The depth and quality of the Department's insight into these issues needs to keep pace with these changes, something it has struggled to achieve so far.
