The land

What is brownfield land?

Brownfield land is land that has previously been developed, typically land occupied by a permanent structure and its associated fixed surfaces. It can include former industrial, commercial or other built sites. Its history does not automatically make it contaminated, available or suitable for housing. A brownfield register identifies sites a local planning authority considers appropriate for residential development under the register rules; it is not a complete inventory of all previously developed land.

The housing supply

Why does viability matter?

When a council says brownfield land can meet local housing needs, the number of potential homes on a map is only a starting point. Housing land supply depends on whether sites are suitable, available and achievable in the relevant period, including whether development is economically viable. A brownfield register entry alone is not evidence that homes will be built within five years. Where robust evidence shows a site cannot viably come forward in that period, its homes should not be relied on as five-year deliverable supply; the council should adjust the assumed timing or capacity and revisit it if credible funding or other changes resolve the constraint.

Brownfield records

Current entries appear first. Ended entries remain available for completeness. A register entry does not mean a site is for sale or has planning consent.

Map markers show a recorded point, not a site boundary. Records without coordinates have a source link but no map. Open the official national map ↗

Set one scenario for the list

These inputs apply equally to every site. Change them to see how the two scenario lists move. They are not site-specific appraisals.

What the labels mean

Scenario viable means residual land value exceeds the assumed existing use value plus premium. Scenario unviable means it does not. A record lacking positive dwelling capacity or area is cannot screen.

Actual existing use value is not in this register. The £/ha input is a single hypothetical proxy, displayed separately from source data. No site gets a claimed current use value.

The model omits many costs and differences between locations. Its lists are sensitivity examples, not investable site rankings or planning viability determinations.

Planning viability guidance

Government guidance describes benchmark land value as existing use value plus a premium. The actual EUV and premium need evidence for each site.

Housing appraisal guidance

Development appraisals involve more than the simplified inputs here, including site-specific costs, policy requirements and timing.
