What is the difference between the wayleave agreement and a route approval?

The wayleave is an agreement in place to allow us to deploy the apparatus required to provide you with network services. A route approval is a caveat within the wayleave agreement that stipulates no installation will take place until a full survey pack has been reviewed and approved for installation by the owner. Essentially the wayleave is annexed with all relevant premises, signed by both parties for completion. The route approval process then falls into place.
