[HEADLINE] Labour's fast-track planning zones: what they mean for land values, viability, and housing delivery across England

[SUMMARY] Labour's Planning and Infrastructure Bill promises to unlock 300,000 homes a year through fast-track planning zones, mandatory local targets and Grey Belt reform — but REalyse data shows England recorded only around 103,500 new build transactions in 2024, and over 717,000 consented units remain stuck in the delivery pipeline. The gap between planning permission and completed homes is the real battleground, and the answer will be written in land values, scheme viability and build-out rates across England's growth corridors.

England is building at a third of the speed it needs to

The headline number is unambiguous. The government's target is 300,000 new homes a year. Land Registry data, tracked through REalyse, recorded approximately 103,500 new build residential transactions registered across England in 2024 — roughly one-third of what the target demands.

This is not purely a planning consent problem. The REalyse planning pipeline shows that between 2023 and 2025, approximately 797,000 residential units received approval in England, equivalent to around 265,000 a year — a figure that, on paper, is tantalizingly close to the target. But a further 717,000 units sit in pending applications, and 153,000 units were refused across the same period.

The bottleneck, in other words, is not just getting planning permission. It is translating consent into completions. That is precisely where Labour's fast-track planning reforms are intended to intervene — and where the real winners and losers will emerge.

What Labour's Planning and Infrastructure Bill actually changes

The Planning and Infrastructure Bill, introduced in 2025, represents the most significant overhaul of the English planning system since the 2004 Planning and Compulsory Purchase Act. The centrepiece is the creation of National Development Management Policies (NDMPs), which will override local plan policies on a defined set of strategic matters — effectively removing a layer of local discretion that has historically slowed major residential schemes.

Alongside this, the Bill introduces a fast-track approval mechanism for schemes that conform to an adopted Local Plan, compresses statutory consultation windows, and strengthens the ability of Planning and Infrastructure Commissioners to intervene in authorities that persistently under-deliver.

The reinstatement of mandatory local housing targets — abandoned under the previous government — means that councils can no longer set their own numbers downward. Authorities in high-demand growth corridors are being handed some of the largest uplifts: parts of the Cambridge–Oxford Arc, the M11 corridor, Outer London boroughs and the wider South East face target increases of 40–80% compared to their most recent figures.

The Grey Belt designation is an additional lever. Land on the urban fringe previously categorised as lower-quality Green Belt can now be released for residential development under a "golden rules" framework — requiring 50% affordable housing, infrastructure contributions and design standards. For land owners and developers holding sites in these zones, the policy shift is material.

The regional delivery gap — and where it is most acute

REalyse transaction data makes the regional picture starkly clear. In the two years to mid-2026, new build completions were led by the South East (approximately 14,000 transactions), the North West (approximately 13,900) and the East of England (approximately 12,500). London, despite its chronic housing shortage, recorded only around 11,600 new build transactions — a reflection of acute viability pressure in the capital's mid-market.

Yorkshire and the Humber is the outlier at the lower end, with approximately 5,500 new build transactions over the period — suggesting that even in markets where land is cheaper and consents are available, developer appetite and infrastructure investment are not following through.

For the government's 300,000 target to be credible, the annual shortfall of roughly 200,000 homes needs to be distributed meaningfully across the regions. That means the North West, West Midlands, East Midlands and Yorkshire corridors — where land supply and brownfield opportunity are comparatively strong — must accelerate significantly. The fast-track zone mechanism, if effectively implemented, is most likely to move the needle in these markets first.

New build premiums: where viability holds up and where it does not

One of the most revealing data points in the REalyse dataset is the gap between new build and existing property prices by region. This new build premium is a proxy for scheme viability: a wide premium suggests developers can absorb land costs, build costs and affordable housing obligations and still generate an acceptable margin. A narrow premium signals viability stress.

The data from the last two years shows the premium ranging considerably across England:

• Yorkshire and the Humber: New builds averaged approximately £267,000 against existing stock at £177,000 — a premium of around 50%. Headline viability looks strong, but transaction volumes are the weakest of any English region, pointing to demand-side constraints and infrastructure gaps rather than a planning bottleneck.

• London: New builds averaged approximately £790,000 versus £619,000 for existing stock — a 28% premium that sounds healthy until set against London's land acquisition costs, CIL rates, s106 obligations and affordable housing requirements. REalyse data consistently shows that viability in many inner and mid London boroughs is only marginally positive for market-rate schemes, which explains why BTR and co-living formats have grown as alternative delivery vehicles.

• South East: New builds at roughly £455,000 versus £412,000 for existing stock — a premium of only around 10%. This is arguably the most policy-sensitive region. With the highest mandatory target uplifts proposed and significant Grey Belt release planned along the M25 and M3 corridors, viability will be squeezed further if build costs continue rising and if affordable housing obligations on Grey Belt land are enforced at the 50% level.

• East Midlands and North West: Premiums of 21% and 27% respectively, combined with meaningful transaction volumes, suggest these are among the most viable regions for volume housebuilding. Nottingham, Leicester, Manchester and Liverpool all have brownfield land pipelines and relatively lower build cost bases that, in theory, should allow schemes to stack up under the new policy framework.

The viability tension at the heart of Labour's programme is this: the Grey Belt golden rules demand 50% affordable housing, but in lower-value markets, even a 20% affordable requirement can render a scheme non-viable without grant subsidy. The reformed Homes England — with its expanded investment mandate — will need to deploy a meaningful quantum of grant funding if the golden rules are not to become a de facto barrier to the very development they are designed to unlock.

Growth corridors: where fast-track zones could make the biggest difference

The spatial logic of Labour's housing programme leans heavily on a small number of high-potential corridors: the Cambridge–Milton Keynes–Oxford Arc, the South Yorkshire Mayoral Authority zone, the West Midlands Combined Authority area, and designated New Town locations including at Tempsford and East Hemel Hempstead.

In these areas, the interaction between fast-track planning and infrastructure investment — specifically in rail, roads and utilities — will determine whether the ambition translates into spades in the ground. REalyse planning data shows that large-scale residential schemes (250+ units) in these corridors frequently face multi-year pre-application processes, with decision timelines of 18–36 months from submission to consent for anything involving strategic highway or utilities infrastructure.

The Bill's provisions to allow NDMPs to direct planning decisions on infrastructure-dependent schemes, combined with a reformed Development Infrastructure Levy (replacing CIL and simplifying s106 in many cases), should in theory compress these timelines. If decision periods can be brought down to 12–18 months for conforming schemes, a meaningful portion of the 717,000-unit pending pipeline could convert to consents — and eventually completions — within a four-to-five year window.

Land values in these corridors are already responding. REalyse data and wider market intelligence suggest that residential land in identified growth zones along the Cambridge Arc has seen upward pressure on option and promotion agreement terms as landowners factor in the reduced planning risk that fast-track status implies. That is a rational response — but it also means that some of the viability benefit of faster planning may be absorbed into higher land prices rather than passed through into affordable housing delivery or lower sale prices.

Conclusion: consents are necessary but not sufficient

Labour's planning reforms are the most ambitious attempted in a generation, and the data supports the case that planning — particularly in the pending pipeline — is a genuine constraint. But consenting 300,000 homes a year is not the same as building them.

The real test of the fast-track planning zone policy will come in 2027–2029, when schemes granted consent under the new framework are due to reach site start. The regional gap in delivery, the viability squeeze on Grey Belt sites, the capacity of Homes England grant to make lower-value markets work, and the ability of the construction sector to absorb a step-change in output will all determine whether the 300,000 headline becomes a reality or remains, as it has for decades, an aspiration that outpaces delivery.

For developers, investors and lenders, the immediate priority is identifying which sites in which corridors have the strongest combination of planning momentum, infrastructure commitment and margin headroom. That analysis — at postcode district level, by property type and scheme size — is precisely where data-led underwriting will separate the credible opportunities from the speculative ones.
