Why land transparency matters now

For decades, the journey from agricultural field to finished housing estate has been shrouded in commercial secrecy. Option agreements, promotion contracts and conditional land deals often lock up sites for years without appearing on any public register. The result: local authorities struggle to identify genuine delivery partners, communities lack visibility on who controls future development, and competing developers cannot assess realistic land supply.

The government's response comes via powers granted under the Levelling-up and Regeneration Act 2023. Draft secondary legislation, expected to be laid before Parliament later this year, would establish a national register of development land agreements covering England and Wales, with a target effective date of April 2027.

What the new rules will require

Under the proposed framework, any party entering into an option, conditional contract, or promotion agreement on land with residential development potential must notify HM Land Registry within 30 days. The register will capture key details including the parties involved, the duration of the agreement, and the broad nature of conditions attached.

Existing agreements will also fall within scope. Landowners and developers holding legacy options will have a 12-month transition window to register retrospectively once the rules take effect.

REalyse data shows the scale of activity these rules will touch. Across England and Wales, planning applications for private housing, build-to-rent and affordable housing totalled around 35,000 submissions in 2024 and 2025 combined, representing over 845,000 proposed residential units and more than £150 billion in estimated scheme value. Many of these schemes rest on land agreements that currently exist only in private contract files.

The land ownership landscape

Understanding who holds land is central to the policy rationale. Analysis of land title data in England reveals approximately 27 million registered parcels. Private individuals own the largest share—nearly 23 million parcels—while corporate and business entities hold over 3 million. Local authorities, county councils, housing associations and non-profit organisations collectively account for more than 1.2 million additional parcels.

The complexity increases when considering that a single development site may involve multiple titles, split ownerships, and layered contractual interests. A promotion agreement with a farming family, for instance, might sit alongside an option held by a housebuilder and a ransom strip owned by a local council. Today, piecing together these relationships requires expensive legal searches and industry contacts. The new register aims to democratise that intelligence.

Implications for the market

Increased competition and price discovery

Greater transparency should sharpen competition for strategic land. Where a single promoter once quietly assembled a site over several years, rivals will now see those moves in near real-time. This could compress option periods and push landowners toward earlier decisions—potentially accelerating deal timelines but also intensifying upward pressure on land prices in high-demand areas.

Due diligence and investment underwriting

For institutional investors and lenders, the register will become a valuable due diligence tool. REalyse analysis of planning pipelines already helps clients identify development hotspots and assess local competition. Adding visibility on underlying land control will enable more robust underwriting of residual land values and delivery risk.

Strategic planning for local authorities

Councils responsible for housing delivery targets will gain a clearer picture of which sites are genuinely controlled and by whom. This should improve the quality of five-year housing land supply assessments and help planners distinguish between "deliverable" and merely "available" sites.

Preparing for April 2027

Property professionals should begin auditing their existing land positions now. Key steps include:

• Cataloguing current agreements: Identify all options, promotion contracts and conditional arrangements in the portfolio, along with expiry dates and notification requirements.

• Reviewing confidentiality clauses: Many legacy agreements include strict confidentiality provisions. Legal teams should assess whether these conflict with incoming disclosure obligations and negotiate amendments where necessary.

• Updating due diligence workflows: Investors and acquirers should plan to incorporate register searches into standard site appraisals once the database goes live.

Outlook

The proposed disclosure regime marks a significant shift toward openness in the land market. While some promoters and strategic land buyers may view the rules as unwelcome scrutiny, the broader industry stands to benefit from reduced information asymmetry and more efficient price discovery.

With hundreds of billions of pounds in residential development flowing through the planning system each year, the stakes are high. Those who adapt their processes early will be best positioned to compete in the transparent market that lies ahead.
