It would be substantial works that would be carried out for each site and each development. This definition of "commenced" is much clearer in terms of what is being asked of a developer. I cannot tell the Deputy now what the regulations will be but they would be substantial. It would be unusual, given the requirements that would be set down in the regulations, that developers would move on to a site, carry out works to a certain level and then move offsite and leave the site sitting there. I am not sure it would be financially viable for anybody to do that.
