Curiosities: what Jersey's own data actually shows
7 genuinely computed findings from this site's own sold-price register, planning register and street index — not a survey, not a hunch. Each one states the likely real cause, or the risk of reading too much into it, before the link to the fuller page behind it.
59% of every recorded Jersey property sale completes on a Friday
Of 33,545 dated sales on the Places.je register since 2001, 19,657 (58.6%) fall on a Friday — 66.4% of just the weekday sales. No other day comes remotely close.
This isn't a homebuyer preference for Fridays — it's a Jersey conveyancing artifact. Freehold and flying-freehold sales complete via a Contract passed before the Royal Court, which sits for that purpose only on Friday afternoons. Share Transfer purchases (common for flats) skip the Royal Court entirely and can complete on any day of the week — so this number describes Jersey's legal process, not when people actually choose to move.
June sees more completed sales than any other month — January the fewest
3,152 sales completed in June (9.4% of the 33,545-sale total) against just 2,075 in January (6.2%).
That's a gentle skew, not a dramatic spike — 9% vs 6% either side of an even 8.3% share each month would carry. It also measures when sales legally complete, not when a property first comes to market or a buyer first views it — this site can't yet answer that separate question with real data, because the nightly stock snapshot it would need has only just started running (see /stock-history).
The biggest price gap between two neighbouring parishes
St Martin's average sale price over the last 5 years is 61% higher than neighbouring St Saviour's (£1,285,523 vs £797,389, 225 and 724 sales respectively).
This compares raw averages across parishes with very different numbers of sales, and takes no account of what's actually for sale in each one — a parish with a larger share of big detached houses and land, next to one with more flats and terraces, would produce exactly this kind of gap without anyone paying a genuine "location premium." An average is also pulled around by a handful of very expensive sales in a way a median wouldn't be.
Not every type of planning application is approved at the same rate
Demolish & rebuild dwelling applications are approved 75% of the time — less often than the 86% island-wide average across all decided applications (142 decided).
A lower approval rate for one type of work doesn't by itself mean planning officers are harder on it. Applicants self-select what they apply for — a demolish-and-rebuild is inherently a bigger intervention than a loft conversion, and people filing for one may already be attempting something more contested (a bigger footprint, a listed building, a sensitive site) than people filing for the other. The gap may describe what gets applied for, not how it's judged.
Approval rates differ noticeably by parish, too
Planning applications in St Lawrence are approved at 82% — 7 points below the island-wide average of 89% (198 decided applications).
Same caution as above, by geography instead of type of work: a parish's approval rate reflects the mix of what gets applied for there — more listed buildings, more coastal or Green Zone sites, more contested developments — not necessarily a different planning standard from one parish to the next.
One Jersey street has more recorded sales on file than any other
La Grande Route de la Cote, St Clement has more recorded sales on file than any other Jersey street — 669 since 2001.
That's a raw count, not a turnover rate — it mostly reflects how long the street is and how many separate properties sit on it, not that any individual house on it changes hands unusually often. A long arterial road will out-count a short cul-de-sac even if no home on either one is sold any more frequently than average.
38 units at Maisons les Arches, St Helier sold within 90 days of each other
The largest multi-unit sale cluster on file in the last 3 years: 38 separately-addressed units at Maisons les Arches recorded as sold between 6 Jun 2025 and 8 Aug 2025 — one of 43 such events found island-wide over the same period.
This is detected purely from clustering the sold-price register by building and date — it can't say why it happened (a new development's completion wave, a portfolio sale, individual conversions all look the same from address and date alone) or who bought any of the units. Jersey's Public Registry holds real buyer names for freehold Contracts, but only via an in-person terminal with no web access, and most flats transfer by Share Transfer, which doesn't register there at all.
