Jersey Planning Register: an aggregate research summary
A free, aggregate research summary of the Government of Jersey Planning Register — published under the reproduction terms gov.je's own Terms & Conditions set out for research, private study and internal circulation. It carries no cost estimates, no professional-directory links and nothing to sign up for. It is not planning advice, and it does not resolve this site's own broader licensing position on the register — it is simply what those terms permit, presented honestly as research.
Overview
3,402 applications on file, numbered 2023–2026 under the register's own P/YYYY/NNNNN scheme (573 in 2023, 1,153 in 2024, 999 in 2025, 677 in 2026, the latest year still in progress). Of these, 3,221 (94.7%) have a recorded outcome and 181 (5.3%) are still pending. Among the 3,221 with an outcome: 85.7% approved, 10.5% refused, 3.8% withdrawn (2,760, 339 and 122 applications respectively).
Where the applications are
St Helier, St Brelade, St Saviour — 3 of the register's 14 address areas (Jersey's 12 parishes plus St Aubin and Gorey, both villages rather than parishes) — together account for 1,701 applications, 50% of everything on file. St Helier alone is 882 applications (25.9%), more than the next two parishes combined. Approval rates vary by parish, from St Aubin's 93% down to St Lawrence's 82% (both figures over 20+ decided applications) — a real spread, though nothing here explains why: it isn't broken down by the type or scale of work each parish actually receives.
| Parish | Applications on file | Share of all | Approved |
|---|---|---|---|
| St Helier | 882 | 25.9% | 91% |
| St Brelade | 500 | 14.7% | 88% |
| St Saviour | 319 | 9.4% | 91% |
| St Martin | 250 | 7.3% | 88% |
| St Peter | 241 | 7.1% | 90% |
| St Lawrence | 222 | 6.5% | 82% |
| Trinity | 222 | 6.5% | 90% |
| St Clement | 191 | 5.6% | 89% |
| St Ouen | 180 | 5.3% | 87% |
| Grouville | 179 | 5.3% | 92% |
| St John | 149 | 4.4% | 85% |
| St Mary | 92 | 2.7% | 89% |
| St Aubin | 41 | 1.2% | 93% |
| Gorey | 18 | 0.5% | 87% |
Parish is inferred from each application's own address text — the register carries no separate parish field. Checked directly across all 3,402 rows: 33 (1.0%) don't resolve to a recognised parish at all, and 117 (3.4%) match more than one — typically because a description references a neighbouring parish by name. Parish counts here are directional, not an exact partition.
What kind of work the applications are
Applications are classified automatically from their own free-text description into 13 categories, the same classifier used elsewhere on this site (see Methodology below). The largest single category, Internal alteration / change of use (1,422 applications, 41.8% of all), is also the classifier's catch-all — anything that doesn't match a more specific pattern lands there, so its size partly reflects the model, not only the work itself. Among categories large enough to measure (30+ decided applications), approval rates range from Re-roofing at 90% down to Demolish & rebuild dwelling at 75%. Time from received to decision also varies: a median of 47 days for Boundary / access works against 80 days for Demolish & rebuild dwelling — the same category with the lowest approval rate, consistent with more contested applications simply taking longer to resolve.
| Type of work | On file | Share of all | Approved | Refused | Withdrawn | Pending | Median days to decision |
|---|---|---|---|---|---|---|---|
| Internal alteration / change of use | 1,422 | 41.8% | 88% | 8% | 4% | 75 | 53 days |
| Single-storey extension | 600 | 17.6% | 86% | 12% | 3% | 31 | 55 days |
| Re-roofing | 280 | 8.2% | 90% | 5% | 5% | 18 | 54 days |
| Boundary / access works | 243 | 7.1% | 84% | 13% | 3% | 11 | 47 days |
| Garage / outbuilding / annexe | 232 | 6.8% | 82% | 13% | 5% | 16 | 71 days |
| Two-storey extension | 203 | 6.0% | 83% | 14% | 3% | 10 | 56 days |
| Demolish & rebuild dwelling | 148 | 4.4% | 75% | 18% | 6% | 6 | 80 days |
| Loft conversion | 87 | 2.6% | 86% | 11% | 4% | 3 | 63 days |
| Summerhouse / small garden structure | 85 | 2.5% | 80% | 15% | 5% | 3 | 49 days |
| Swimming pool | 34 | 1.0% | 87% | 13% | 0% | 3 | 57 days |
Approved/refused/withdrawn are percentages of that row's own decided applications; pending is shown as a separate count. Categories with fewer than 30 decided applications on file are left out rather than shown on a sample too thin to mean anything.
A trend we checked for, and aren't showing
The natural next question is whether approval rates are rising or falling over time. Checked directly against the full register: only 900 applications (26%) carry a recorded decision date at all — and every one of those 900 is an Approved outcome. Refused and withdrawn applications carry no decision date in this source. A date-ordered approval-rate series built from that would show 100% approval at every point on the line — not a real trend, an artifact of which outcomes happen to be dated. So this page reports point-in-time aggregates rather than a time series it can't honestly support. The application-number years above (P/YYYY/NNNNN) describe when applications were submitted, not decided, and don't have this gap.
Methodology
Source: the Government of Jersey Planning Register, gov.je. 3,402 applications on file, data last refreshed 2026-08-22. Classification: each application's type of work is inferred automatically from its own description text using a fixed set of pattern rules (the same classifier used across this site) — not stated by the applicant, so a minority of applications will sit in a category a human reader would classify differently, and the catch-all category above is inflated by design. Outcome: read directly from the register's own decision field (Approved / Refused / Withdrawn / Pending). Parish: inferred from address text, with the match-quality figures stated above. What's not shown: no cost estimates, no time trend for approval rates (see above), and no attribution to a named architect, agent or applicant — the register itself carries no such field.
