How long does it typically take to hear from the planning authority?

[cowboy25]

I sent off for a pre application about two months ago now and apart from an automated email response I have not heard anything. How long could it take to hear back from my local planning authority? I'm not desperate to hear from them or anything but I'm just curious, could it take a year or so, a few more months, any idea? Its sort of important as I am building a Shepherds hut and if planning is denied I will alter the design of the hut somewhat to take account of this so I will need to know before long.

iirc there are no statutory limits placed on planning departments, so they can take as long as they want. They might have set themselves a local ambition. Give them a call and ask - there's no harm.
