FAQ
Section 106 agreement questions
Short answers to what land teams ask us before a demo.
What is a section 106 agreement?
A section 106 agreement is a legal agreement between a developer and the council. It secures contributions such as affordable homes, education funding or highway works as part of planning permission.
How does LandBuyer AI assess S106 contributions?
It finds agreements signed for comparable developments within 3 miles, reads them and sets them against adopted policy. Recorded amounts appear as actual cases, not predictions.
Does it show the affordable housing threshold?
Yes. The assessment states the scheme size from which the adopted plan requires affordable housing, and the tenure split by area. On Kew Yard the threshold is 15 net dwellings.
Can I read the agreements themselves?
Yes. Each comparable development links to its signed agreement and to the adopted plan pages the assessment relies on, so you can check the wording.
When is a section 106 agreement needed?
When an obligation is needed to make a development acceptable in planning terms. Each obligation must also be directly related to the development and fairly and reasonably related to it in scale and kind.
