LandControl/Professionals/Readers
From April 2028 HM Land Registry publishes the contractual control dataset free, in a structured searchable form, at least monthly. Ownership was always visible. Control was not. That is the gap this data closes, and the gap existing land platforms have never been able to fill.
What to do now
01
Join the dataset to title polygons, local plan allocations, constraints and planning history. A field under option, allocated residential, with no application yet, is a story.
02
Grantees are companies, often SPVs. Match company numbers through Companies House to parent groups so Barratt, Persimmon and Vistry roll up as land banks, not as 300 subsidiaries.
03
Assignments, variations and exercises are reported as they happen. A variation extending a control period, or an assignment to a new promoter, is signal.
04
Every record carries a duration. Rights ending with no planning submitted are the sites a competing promoter should be looking at two years out.
Location and extent of the land affected, the identity of the grantee, the type and duration of the right, and the date it was granted or exercised, plus subsequent assignments, variations and exercise events. HMLR has designed the submission service to capture machine-readable geometry for part-title rights specifically so the dataset can be searched geographically.
Consideration. No option fees, purchase formulas or promotion splits. No unregistered land. No overage or clawback. No agreements that predate 8 June 2026 unless later varied, assigned or exercised. Read it as a map of control, not a market of prices.
Searchland, LandTech and Nimbus will add a contractual-controls layer within weeks of the first release; the data is free and they already have the mapping. The value sits in what is derived: resolved corporate groups, expiry pipelines, momentum scores, week-on-week activity by developer and region, and a history that starts in April 2028 and compounds. A platform that ingests from month one and never misses a drop holds something a late entrant cannot rebuild.
The ingestion schema, the Companies House resolver and the planning-data joins can all be built against today’s public datasets. The only thing missing is the control layer, and it arrives on a known date.
