FAQ
Affordable housing questions
Short answers to what land teams ask us before a demo.
What are the affordable housing requirements for developers?
They come from the adopted local plan policy: a threshold in net homes, a percentage by policy zone and a tenure split. LandBuyer AI reads the policy for the site's authority and states each one. Sefton's applies from 15 net homes.
How does LandBuyer AI show affordable housing need?
It shows households on the housing register and homes delivered over six years. Sefton had 3,382 households on the register at 31 March 2025 and 1,173 affordable homes delivered from 2019-20 to 2024-25.
Does it set the affordable share for my site?
No. Borough precedents show S106 is routinely used but set no figure for a scheme. The affordable share and S106 terms for a site are tested against the adopted policy.
Where does grant come in?
Homes England grant is shown as a programme route, not an allocation. The AI insight says to keep it out of land value until a written allocation or partner offer is in hand.
