Linked development applications

These links are inferred by lobbyTO from file numbers and addresses named in the registration (task L2); the registry does not record which application a registration concerns.

Links between records are inferred by a model and are not reviewed by a person. Each link shows its score out of 1; moderate-confidence links (0.7 to 0.9) are wrong more often than high-confidence links. How links are scored

Disclosure timeliness

Lobbyists must record a communication within 3 days. lobbyTO measures the gap between a communication's date and the first daily snapshot of the registry export in which it appears. The export refreshes daily, so a 1-day gap is expected.

Measurement in progress. Daily snapshots began on 4 October 2026 (2 days of snapshots so far); results appear after 6 months of snapshots, from 4 April 2027. Communications dated before the first snapshot are not measured.

City contracts and lobbying

No City contract awards are recorded for this organisation in the TOBids contract datasets.
