LPAs make extensive use of electronic systems for reasons of efficiency and also to encourage transparency. Almost all have their own website and electronic document management systems where planning applications can be viewed and commented upon, along with local planning policy documents viewed and a wide range of other relevant sources. Provided that architectural drawings and other supporting documents are in electronic form then planning applications should ideally be submitted on-line, either via the LPA's website or via the UK-wide "planning portal" website which provides a nationwide clearing house on planning information and facilities.
