Essex council area

Selling Land in Harlow

Harlow is the smallest council area in Essex, a post-war new town whose plan was adopted in December 2020 and whose last published land supply fell short of five years. For owners of land in and around the town, that makes the detail of each site count for more than the headline score.

A New Town Drawn on a Tight Boundary

Harlow Council covers a single new town, designated in 1947 and planned by Frederick Gibberd. Its neighbourhoods, from Old Harlow and Mark Hall to Church Langley, Newhall and Potter Street, are kept apart by Green Wedges, and together the neighbourhoods and wedges make up most of the council area.

The smallest council area in Essex. The plan puts its land area at 30.5 square kilometres, and records that the tight boundary is a legacy of the new town designation.
Only 15% Green Belt. That is the plan's own figure. A larger share, 24%, is Green Wedge or Green Finger, a local designation with its own policy.
Close to target, with an action plan due. In the Housing Delivery Test 2025 the council built 1,114 homes against 1,224 needed, a result of 91%.
A plan adopted in 2020. The Harlow Local Development Plan, adopted in December 2020, runs to 2033.
A supply short of five years. The council's 2024 to 2025 monitor found 4.9 years of deliverable housing land at 31 March 2025.
Two stations and a new junction. Harlow Town and Harlow Mill stations lie in the north and north east of the town, and the plan describes the new Junction 7a on the M11, to the north east, as supporting current and future development.

Harlow has little open land of its own, and most of its big growth is planned just over the boundary. What remains inside is small, awkward or tightly protected, which is where careful evidence makes the difference.

The 4.9 Year Supply, and What Has Changed Since

The council's Housing Land Supply Monitor for 2024 to 2025 measured supply against the plan's own requirement, because at 31 March 2025 the plan was still less than five years old. That requirement is at least 9,200 homes between 2011 and 2033, stepped from 361 a year up to 2024 to 501 a year from April 2024. With a 5% buffer added, the council found 4.9 years of deliverable sites.

Three details in that monitor matter to a landowner:

Building slowed sharply. Only 118 homes were completed in 2024/25, against a target of 501. The monitor explains that larger sites such as Gilden Park had been built out, while existing permissions and the East of Harlow strategic site were slow to build.
The big sites have moved back. The Authority Monitoring Report expects 850 homes at East of Harlow by 2032/33, although the plan allocates about 2,600 there within the district. None had been built there by March 2025.
No allowance for windfall. As a planned new town, the council says, few unplanned sites come forward, so it counts none. Every small site that gains permission adds supply the council has not banked.

Now that the plan is more than five years old, national policy measures supply against the government's standard method figure rather than the plan's own requirement. The 2024 to 2025 monitor predates that change, so the next one is expected to be the first measured against the government figure.

Under the August 2026 National Planning Policy Framework a supply shortfall counts as evidence of unmet need, the first test in the policy S5 route for land outside settlements. S5 does not apply in the Green Belt, though, and the plan describes Harlow as surrounded by it. Here the shortfall does its most useful work in the grey belt test on the edge, where a shortage of homes is one of the conditions, and in the balance on land inside the town. Our guide to the 2026 NPPF shows how these policies fit together.

Green Wedges, Green Fingers and the Green Belt Edge

Most open land in Harlow falls under one of three policies, and they work very differently:

A summary only. Each site turns on its own boundaries and evidence.
Designation	How the plan treats it	What that means for a site
Green Belt (policy PL4)	Severely restricted, with exceptions such as limited infilling and reuse of previously developed land where openness is preserved.	National policy now adds grey belt. Land that contributes little to the Green Belt purposes can be considered for homes if need is shown and the Golden Rules are met.
Green Wedges and Green Fingers (policy PL5)	Allows small-scale development, infrastructure with community benefit, or changes to existing buildings, provided the role and setting of the wedge are preserved.	Not Green Belt, so the grey belt test does not arise. Policy WE2 gives the wedges roles in separating neighbourhoods and keeping their open character.
Land inside the built-up neighbourhoods	Covered by the plan's general policies and allocations.	National policy S4 favours homes inside settlements; refusal needs harm that substantially outweighs what the scheme offers.

Here the Green Belt is only a thin rim, while the wedges run into the middle of the town. A wedge is rarely the place for a housing scheme, but land along its edges and plots that have lost their open character are worth checking against the policies map.

On the Green Belt rim, the grey belt question usually turns on checking the spread of the town and keeping it apart from its neighbours, as our grey belt guide explains.

Growth Over the Boundary: The Garden Town

Harlow and Gilston Garden Town was designated by the government in 2017. It is run by five councils, East Herts, Epping Forest, Essex County, Harlow and Hertfordshire County, and plans for 23,000 homes in four new neighbourhoods, Gilston, East of Harlow, Latton Priory and Water Lane, together with regeneration of the town centre.

Of the four, only East of Harlow is allocated within the council area; the plan places Latton Priory and Water Lane in Epping Forest district and Gilston in East Hertfordshire. Land on the edge of the garden town may therefore be decided by a neighbouring council, under its own plan.

Progress has been slow. In March 2026 the Garden Town's chief executive told Your Harlow that homes and infrastructure had not progressed at the pace and scale envisaged in 2017, and spoke of a significant funding gap for the infrastructure still to come.

Why Slow Strategic Sites Help Smaller Land

The council's supply depends on a handful of large sites, so each year of delay shows at once in its five-year figure. A small, ready site fills a gap the big sites cannot, which gives it more weight than its size suggests. The Princess Alexandra Hospital site shows the same pattern: the supply monitor now places the homes planned on the existing hospital site beyond the plan period.

Costs and Conditions on a Harlow Site

Permission in Harlow comes with obligations that shape what a site is worth:

Affordable housing. The plan expects at least 30% affordable housing on schemes of more than 10 homes.
Epping Forest and Hatfield Forest. Policy WE4 recognises that new homes can harm the Epping Forest Special Area of Conservation through visitor pressure and traffic pollution. Mitigation can mean green space on the site, or contributions to access management in Epping Forest or Hatfield Forest and to air quality.

These come off the value of a scheme along with section 106 contributions and biodiversity net gain, so the price we agree reflects them from the outset. You pay none of them yourself.

Land We Look for in Harlow

Yards, depots, garages and commercial land inside the neighbourhoods.
Large gardens and backland plots with a workable access.
Green Belt land on the edge of the town that is enclosed by roads, homes or other development.
Previously developed land in the Green Belt, such as old nurseries or equestrian yards.
Land within an easy walk of Harlow Town or Harlow Mill stations.
Land just outside the boundary, in Epping Forest or East Hertfordshire, next to the Garden Town sites.

Land deep inside a Green Wedge is harder, and we will say so. Where a site shows promise, the arrangement is simple: we agree a fixed price at the start, above what the land is worth today, and pay for every report, application and any appeal ourselves. Once permission is secured we complete and you receive that price; if it is not, you keep your land and owe nothing. The full sequence is on our how it works page.

Harlow's New Plan, the Next Test and a Supply Reset

The Delivery Test

The Housing Delivery Test 2025 was published on 17 August 2026 and covers April 2022 to March 2025. The council's last monitor relied on an earlier edition that needed neither a buffer nor an action plan. At 91%, national policy now asks the council to prepare an action plan setting out how it will improve delivery.

The test comes round every year. Slipping under 85% would mean a 20% buffer on top of the five-year requirement, and under 75% unmet need would be taken as shown; reaching 95% would end the action plan duty. The next edition drops 2022/23 and adds 2025/26, and with only 118 completions in 2024/25 already inside the window, we make no forecast.

The Five-Year Supply

If the next monitor, measured against the standard method, confirms a shortfall, the case for well placed land inside the town and on the Green Belt edge grows. If it shows five years or more, the new plan becomes the main route for larger land, while small sites inside the town still start from policy S4.

The New Local Plan

The council's Local Development Scheme of March 2025 plans a new Local Plan under the reformed system. It shows informal work, including a call for sites, to December 2025, a first formal consultation from October to December 2026, a second in October and November 2027, submission in March 2028 and adoption in November 2028. The scheme says it will be revised if the final regulations differ; we have not seen a newer version.

Reorganisation, on Hold

In March 2026 the government decided Harlow would join Epping Forest and Uttlesford in a West Essex council from April 2028. That decision was withdrawn on 7 September 2026 and a review is under way, with the May 2027 elections held on existing boundaries. Harlow Council remains the planning authority.

What This Means for Timing

For land that depends on the new plan, the first formal consultation, which the council's timetable places in late 2026, is the moment to have evidence ready, and our guide to call for sites and local plans explains what that involves. For small sites inside the town and previously developed land on the edge, nothing needs to wait for the plan.

Questions About Land in Harlow

My land is in a Green Wedge. Can it ever be developed?

Occasionally, in a limited way. The plan allows small-scale development and changes to existing buildings where the wedge's role and setting are preserved. A full scheme in the middle of a wedge is unlikely, but land on its edge or with existing buildings deserves a look.

Harlow scored 91%. Does that help an application?

Only indirectly. At that level the council must prepare an action plan, but need is not treated as unmet on the score alone. The five-year supply does more of the work: the last published position was 4.9 years.

My land is on the edge of Harlow but outside the council area. Who decides?

The council for the district it sits in. Latton Priory and Water Lane are in Epping Forest district and Gilston is in East Hertfordshire, so land beside them is judged under those councils' plans. We look at land on both sides of the boundary, and our Essex county page covers the neighbouring councils.

Is a small site of a few homes worth your time?

Yes. The council counts no unplanned sites in its supply, so a small site that can be built quickly adds homes it needs. We review sites of every size.

Should I wait for the new Local Plan?

Not necessarily. On the council's own timetable adoption is late 2028. Land inside the town, or previously developed land on the edge, can often be taken forward now.
