How long does it take to get planning permission approval?
Once you have submitted your application and paid the correct fee, the planning department will check to see that all the relevant information was submitted along with the proposal application before considering your application. Local planning authorities typically take between 8 to 12 weeks to determine planning applications, except if your application is not of the usual variety and requires more time.
During this period, a sign may be placed in front of the address where the proposed development is planned so that neighbors who feel the development will affect them can write their concerns to the local planning authority. The authority will also consult with a few important agencies such as the Environmental Agency (for an EIA) and the local highway department before approving or rejecting your application. But if all the necessary information is provided from the start and what you are planning is a straightforward development, you can expect to hear from the council in less than 12 weeks.
