What stands out

#signature ⧉

What this sector actually does

A sector is a label; a capability is a service someone published and we resolved to the graph. 77% of the sector carry at least one, and the typical one among them carries 6 capabilities.

137 of the 203 with a capability on record span two or more of these groups (67%). Two capabilities inside one group are one trade, not two, which is why this counts groups rather than nodes.

Sub-sectors

IT & Technology leads, on 52 organisations

Every organisation is counted once, in its primary sub-sector. Separately, 43 organisations outside this count work in Professional Services alongside another sector — they are not in the bars below.

Counts each organisation's primary sub-sector, so the bars sum to the sector, and each is the roll call the directory lists under that name.

3 organisations are classified straight at sector level with no sub-sector — a real cohort, kept visible rather than folded into the largest bar. 43 further organisations work in Professional Services alongside another sector and are not in these bars: each is counted in the sub-sector of the sector it calls its main line. "Works in", never "is in".

The same island, drawn on a location quotient: this sector's share of a parish against its share of the island. Hatched parishes hold too few of this sector to compare at all. Parishes holding fewer than 30 of this sector are drawn and tabled but never named in a sentence: a quotient over a handful of organisations moves on one new record, and a superlative that flips that easily is not one.

Founding years

Half of those with a founding year began after 2006

The island's median is 2006. Counts organisations still trading that publish a founding year; older firms are likelier to do so — survivorship and reporting bias at once.

Capabilities

The typical mapped organisation holds 6 capabilities, against 3 island-wide

77% of the sector have at least one service resolved to the graph, across 11 domains, against 71% island-wide, the 4th-highest capability coverage of the 13 sectors where it can be counted. Capabilities as published by each organisation and resolved to the graph; a business with no capability claim is not necessarily a business that does none of these things.

Online presence

#digital ⧉

86% of Professional Services organisations have a website of their own

Against 67% island-wide — 19 points above the island rate, the 2nd-highest own-site rate of the 15 sectors where it can be counted. The gap is the robust part: the sector’s own rate is measured over the organisations we have found, and the ones still missing are disproportionately the web-invisible.

Legal form and ownership

Legal form, ownership and size — as far as they are published

These are published far less often than a phone number. Each module below states its own coverage, and renders the gap rather than a confident number over a silent base.

As each organisation describes itself. Where a parent is off-island, that is recorded only when it was found — there is no “no parent” record, so this is not a count of independence.

Memberships and regulators

What this sector says it belongs to

Memberships, regulatory statuses and certifications as each organisation publishes them, folded to the name they share. This is a text-match floor, not a licensee count — the register itself is the authority on who is licensed.

How this chapter counts

#method ⧉

The bases every figure here divides by

This chapter counts over the 262 active organisations whose primary sector is Professional Services — 7% of the 3,582 with a primary sector on record; the wider 305 who work in Professional Services at all are counted in every sector they work in, and are used only where a sentence says “works in”. Each module then divides by what is actually on record for it — a parish for 240, a founding year for 171, a capability resolved to the graph for 203, opening hours that resolve to a weekly grid for 137 — and those bases are printed under every chart, because the denominator is part of the datum.

This sector’s own coverage was measured at 80% on 30 September 2026, by capture–recapture against Google's business listings for the Bailiwick, with every organisation that was itself added from those listings left out of the comparison so the two counts stay independent. Every count above is a floor.
