It is not anticipated that development contributions adopted under section 48 of the Planning and Development Act 2000, which are levied to fund the provision of local authority infrastructure that benefits development, will unduly affect the price of houses. While the development contribution system was reformed in the 2000 Act, it is continuous with the levying of contributions by local authorities which has operated since the commencement of the 1963 Act. In addition, a circular letter issued on 27 June 2003 advised planning authorities that while it is envisaged that developers should make an appropriate contribution towards the costs of public infrastructure and facilities, the local authority should take care to avoid development contributions that are excessively high.
