Frequent questions we get from our clients about the planning process.

Can we guarantee our clients will get planning permission? 

We cannot guarantee our clients will get planning permission for any project. We work closely with a number of local authorities and understand what their requirements are to meet planning criteria. 

How long does planning permission take?

Your planning decision should take no longer than 8 weeks from the point of application.

My application for planning has been approved, how long does this planning permission last?

Planning permission is typically granted for 3 years; meaning you must begin work within that time or face re-applying.
