As many as half of English councils are currently unable to demonstrate a five-year housing land supply, including a significant number of councils in East Anglia and the surrounding areas.

For landowners, developers and homeowners, this is not just a technical planning issue. It means that land previously ruled out for housing could now be worth reviewing.

In this article we summarise the current housing land supply position for a number of councils across Suffolk, Essex, Norfolk, Cambridgeshire, Bedfordshire and Hertfordshire. We regularly monitor these positions as they can change rapidly.

What is a five-year housing land supply?

Every local planning authority needs to be able to show that enough new homes are due to be built over the next five years to meet the local housing need. This is known as a five-year housing land supply.

The five-year supply is primarily made up of sites that either have planning permission or are allocated for housing in the local plan. Sites should not be included if there is clear evidence that homes will not be delivered within the five-year period.

Housing land supply changes from 1 July 2026

Some councils’ housing land supply positions have worsened since 1 July 2026. This is because paragraph 78(c) of the National Planning Policy Framework took effect on that date and now requires the local housing requirement to be increased by 20% in certain areas.

Where paragraph 78(c) applies, a council is effectively required to show the equivalent of a six-year supply. As a result, some councils that previously had between five and six years’ supply will no longer be able to demonstrate a five-year housing land supply.

Understanding the tables

Of the 27 different councils we assessed, only 7 are currently able to demonstrate a five-year housing land supply. That is a significant finding.

The presumption

If a council cannot demonstrate a five-year housing land supply, the presumption in favour of sustainable development is engaged. As a result, the decision-maker must apply the “tilted balance”.

The tilted balance requires planning permission to be granted unless policies protecting areas or assets of particular importance provide a strong reason for refusal, or unless the adverse impacts of the proposal would significantly and demonstrably outweigh the benefits. This is a high threshold for refusal.

When the tilted balance applies, housing applications that conflict with planning policy or cause a degree of planning harm have a much better chance of being approved.

However, the presumption is not a free pass. Proposals that would cause serious planning harm are still likely to be refused. This could include, for example, development that would cause unacceptable danger to motorists or pedestrians, result in the significant loss of high-value trees, or provide a very poor standard of accommodation.

Protected areas and assets, which include Habitats Sites, Listed Buildings, National Landscapes and the Green Belt, also remain subject to a high level of protection. While the tilted balance can still be engaged in these locations and housing applications can be looked on more favourably, it will still be expected that material harm to the area or asset is avoided.

Accepted shortfalls

Where a council accepts that it cannot demonstrate a five-year housing land supply, applicants should be in a stronger position from the outset. The council should apply the presumption when it determines the application. This means applicants should not need to wait until appeal, or spend time and money proving the council’s shortfall to an Inspector, before the correct planning balance is applied.

Size of the shortfall

A council with a supply of 2 or 3 years is in a very different position from a council sitting just below 5 years. The greater the shortfall, the greater the weight given to proposals which deliver new homes. In addition, a larger shortfall should reduce the weight given to restrictive local policies which limit where new housing can go.

Housing numbers

Where there is a housing supply shortfall, applications for a significant number of houses attract more positive weight because they make a larger contribution to addressing the shortfall. That does not mean larger schemes are always more likely to succeed, however, as they can have bigger impacts and cause more planning harm.

Changing figures

Housing land supply figures are inherently changeable. They depend on factors such as housing requirements, local plan allocations, build-out rates, permissions granted, permissions lapsing, appeal decisions and changes to national policy.

For that reason, a council’s position can improve or worsen in a short space of time. The figures in the table should therefore be treated as a useful starting point, rather than a substitute for site-specific planning advice.

Can a council’s housing land supply be disputed?

Yes. Housing land supply figures are frequently, and often successfully, challenged at appeal. For this reason, appeal-derived figures can differ from the council’s published position.

In general terms, there are two main ways to challenge a council’s claimed supply.

The local housing need

Firstly, applicants can challenge their housing requirement; this is the minimum number of homes the council needs to plan for. In some cases, the council may be relying on an old housing requirement, or may have failed to apply the correct national policy. This is more likely to be an issue where the local plan is old because national planning policy has changed significantly in recent years.

The supply of sites

Secondly, applicants can challenge their supply of sites.

The council’s supply is made up of a list of specific housing sites and planning permissions that are expected to deliver homes within the next five years. That list is open to scrutiny.

For example, some permissions may have lapsed, while other sites may be progressing more slowly than the council had assumed. Councils also occasionally misapply national policy by including sites that should not have been added in the first place, such as sites with outline permission only and several stages to complete before construction can begin. Wherever there is clear evidence that a site is unlikely to be built-out within the five-year period, it should be removed from the supply.

Large housing sites are particularly important, but also vulnerable, components of the housing land supply. They can add a significant number of homes to the total, but are also more likely to experience delays and setbacks. If just one major site has to be removed, that may be enough to reduce a council’s supply below five years.

Nevertheless, there is always some risk involved in challenging housing land supply at appeal, as the council may be able to point to new planning permissions or updated delivery evidence that brings its supply back above the requisite five years.

Looking beyond settlement boundaries

Many local plans use settlement boundaries to control where new housing can go. These policies are intended to help councils to manage growth, direct development to the most suitable locations, prevent urban sprawl and also to protect the countryside.

However, settlement boundaries are still lines on a map.

In some cases, the distinction between one site and another can be fairly arbitrary. One plot may fall just inside the settlement boundary, while a neighbouring plot or garden falls just outside it. Both sites may still feel like part of the town or village and have similar access to shops, schools, public transport and other local services.

Where a council has a strong five-year housing land supply, it is easier for it to resist development outside the settlement boundary, even if there is little practical difference between land outside the boundary and neighbouring land inside it.

However, where a council cannot demonstrate a five-year housing land supply, that position is much weaker. Sites that are outside settlement boundaries but still well connected to an existing town or village are especially likely to be assessed favourably when the tilted balance is engaged.

The image below illustrates the type of situation where a lack of five-year housing land supply can be particularly helpful. The blue areas fall outside the settlement boundary, so they would not normally be approved for housing under the local plan. However, they are clearly well related to the built-up area and have similar access to local services. Sites in these sorts of edge-of-setttlement locations typically benefit most when councils lose their five-year housing land supply.

Self-build need and supply

As well as general housing supply, councils are subject to a separate legal duty to meet local demand for self-build housing plots. In July 2025, however, Planning Resource reported that around 57% of councils in England were failing to meet their legal duty to permit sufficient self-build plots, based on analysis reported by The Times.

As a result, self-build proposals may have an additional advantage, even in areas with a healthy five-year housing land supply. In fact, Inspectors regularly attach significant or even considerable weight to the provision of self-build housing in areas where the duty is not being met.

Could your land have improved prospects?

If your land has previously been ruled out for housing, it may be worth seeking fresh advice. This is particularly true where the main issue was that the site fell outside a settlement boundary, or conflicted with a restrictive local housing policy.

Of course, a lack of five-year housing land supply will not overcome every planning objection. However, where a site is reasonably well related to an existing settlement and there are no major technical constraints, the tilted balance is much more likely to fall in your favour.

The same broad principles also apply to self-build plots. Where there is unmet demand, applications for self-build housing stand a greater chance of approval, even if the council can demonstrate a general five-year housing land supply.

Planning Direct can review your site, check the current housing land supply position, and advise whether the land may now have stronger development potential. Although this article focuses on councils across East Anglia and the surrounding areas, we can assess sites throughout England. Our initial advice is always free of charge.
