My Lords, the process will not be as my noble friend has described. The simplest way I can describe this is that community land auctions
will be a process of price discovery. In the current system, local planning authorities have to make assumptions about the premium required by a reasonable landowner to release their land for development. For Section 106 agreements, this manifests itself through viability negotiations between the local planning authority and a developer. As these can be negotiated, there is a higher risk that, in effect, higher land prices lead to reduced developer contributions, rather than contributions being fully priced by developers into the amount that they pay for land.
For the community infrastructure levy and the proposed infrastructure levy, a levy rate is set for all development within certain parameters. When setting rates, the local planning authority has to calculate how much value uplift will occur on average, and has to make assumptions about landowner premiums and set a levy rate on that basis. The actual premium required by individual landowners will not be available to local planning authorities and will vary depending on individual circumstances. If the local planning authority makes an inaccurate assumption about landowner premiums, they may either make a lot of sites unviable by setting too high a levy rate, or else they will collect much less than they might have done otherwise by setting too low a levy rate.
Under the CLA process, landowners bid to have their land selected for allocation in an emerging local plan, as I have described, by stating the price at which they would willingly sell their land to the LPA for development. The offer from the landowner, once an option agreement is in place with the LPA, becomes legally binding. The LPA can either exercise it themselves, thereby purchasing the land, or auction it to developers. The competitive nature of CLAs incentivises landowners to reveal the true price at which they would willingly part with their land. If they choose to offer a higher price, they risk another piece of land being allocated for development, in which case they will not secure any value uplift at all.
I do not want to prolong the debate unnecessarily, so I will respond to my noble friend in writing on the other questions I have not covered.
