Who is applying for planning permission in Guernsey
Every organisation — company, trust, public body, club or church — on a Guernsey planning application, from the States of Guernsey Planning Websearch, grouped by name, with a known-builder/developer rollup, work-type mix and an estimated cost of works using the same cost model as this site's /planning pages. Private individuals are counted and never named: a homeowner who applied to extend their kitchen is not a public figure, and the register does not exist to rank them. Generated 2026-08-20. Applicant names that look like a company link out to a Guernsey Registry search (their own search page has no pre-fill link, so you'll need to type the name in — see the methodology note at the bottom).
An honest note on data coverage
The underlying data/planning.json snapshot's real decision dates fall off sharply after 2025-06 (see per-month counts in the investigation notes) — most of its nominal 'decided in the last 3 years' coverage predates the requested trailing-12-month window (2025-08-20 to 2026-08-20) by a wide margin. The strict 'window' report below is consequently thin (32 applications). A supplementary 'secondary_window' report over the most recent 12-month period with substantial real coverage (2024-07-01 to 2025-06-28, 1119 applications) is included for a meaningful 'who is submitting the most' read — see the summary .md for the full explanation.
Requested window: 2025-08-20 to 2026-08-20
32 applicants found in the literal trailing-12-months window (19 by a real decision date, 13 by the year embedded in the application number, used as a fallback where no decision date could be scraped) — every one of them filed exactly once, too thin a sample for a meaningful "who applies most" ranking. Shown here for completeness, not as the headline report.

Methodology
decision window: Trailing 12 months from currentDate (2026-08-20), i.e. 2025-08-20 to 2026-08-20 inclusive.
candidate pool: All 2,120 records in planning.json were scraped (not pre-filtered by app-number year) because spot-checks showed filing year and decision year can diverge by more than a calendar year, so app-year alone is not a safe pre-filter for a decided-in-last-12-months window.
decision date source: Primary: "Decision Notification Date" field scraped from each application's own detail page (more precise than the search-results table, which has no date at all). Fallback when a page had no usable decision date: the year embedded in the application number (e.g. FULL/2025/1006 -> 2025), treated as in-window if 2025 or 2026 — documented per record via decision_date_source.
work type mapping: Reuses src/worker.js WORK_CATEGORIES/classifyWork keyword classifier verbatim for the underlying category and cost range, then maps those categories down to Doug's new build / renovation / extension / other split (see doug_bucket() in build_report.py for the exact mapping and reasoning). One addition beyond the site's existing table: descriptions saying "erect new dwelling" etc. without the word "demolish" are also treated as new build (the site's own table only flags demolish+dwelling together), using the same per-m² demolish-and-rebuild cost range.
cost methodology: Same UK base-range-per-category table and ~25% Channel Islands premium (CI_PREMIUM=1.25) as src/worker.js costRangeHtml(). Per-m² categories (demolish & rebuild / new build) are sized using the matched property's whole floor area from data/listing-enrichment.json where an address match to a current listing exists; otherwise the plain per-category range is used with no size adjustment.
applicant grouping: Grouped on a lightly normalized "Applicant Name" (uppercase, punctuation stripped, LIMITED->LTD, whitespace collapsed) as scraped from each detail page, so e.g. "Guernsey Electricity Limited" and "Guernsey Electricity Ltd" count as one applicant. Personal-name variants are NOT resolved (e.g. "Mr P De Jersey" vs "P De Jersey" still count as two) - no fuzzy/alias matching beyond that punctuation/suffix normalization. Each applicant record carries a name_variants list when more than one raw spelling was folded together. Builder/developer cross-check (data/builders-developers.json) uses the same normalization plus each builder's own registered alias list, applied to both the Applicant Name and Agent fields.
