As someone who has negotiated many s106 Agreements on behalf of developers, I can tell you that local authorities don’t need help with them. They have their own legal departments and if they have a red line they don’t budge from it. If provision of a certain level of affordable housing (or any other planning requirement) makes a development unviable a developer will not buy the site. Site acquisition is almost always undertaken via an option agreement or a contract conditional on the obtaining of a planning permission which is satisfactory to the developer - and the contract will list various planning requirements, such as provision of more than x affordable units, which will render a consent unsatisfactory.
Starmer is working on the basis that the vast majority of the public don’t know how these things actually work and will believe his ‘toughening up’ and ‘assistance’ rhetoric. Empty promises which will impress those who know no better.
I know that LAs have their own legal dept. And what you are saying makes sense.
I was talking to a Canadian friend yesterday, and it is clear that the Canadian government has much more draconian laws compared to the U.K. E.g. rent increase by private landlords, is held this year to 3% by the Canadian government, even though inflation is currently at 6+%.
It seems to me that if we want our housing crises to be resolved, much more stringent law has to come into force.
