We tried to bring together in one report a high-level summary of the pressures that arise from unavoidable commitments, such as the ageing population, the costs associated with deprivation and unemployment, the costs of pay deals, not least in the national health service, energy costs, drug costs, the cost of meeting the European Union waste directive targets by 2020, the combined costs of private finance initiative contracts, non-profit-distributing commitments and capital charges, the build-up in costs of commitments to free services and, last but by no means least, the backlog in the maintenance of the physical estate, which is quite significant at around £4 billion.We have had 10 years of 5 per cent real growth per annum, and at the end of that 10 years, the Audit Scotland reports indicate that the maintenance backlog is still £4 billion, so what does that imply for the future?
