Before making an application, it is advisable to consult any neighbours who might be affected by your proposal, and the local parish, town or community council. In more complicated cases, you should consider consulting other bodies who might have an interest, such as:
- Natural Resources Wales or the local water and sewage company - to discuss any potential sewerage, water or flooding problems;
- the highway authority - usually the Unitary Authority (National Park Authorities are not Highways Authorities) to discuss road safety and traffic issues; and
- the Health and Safety Executive - to discuss the use of any dangerous chemicals in your proposed development.
