What kind of work is Jersey planning actually made of?
3,402 applications on file, classified by wording into the same categories this site uses to estimate cost. This is a breakdown of the WORK, not a ranking of firms — Jersey's planning register carries no applicant, agent or architect field, so unlike guernsey-site's equivalent page, applications here cannot be reliably attributed to a named practice. For firms working in Jersey, see architects and chartered surveyors.
A planning application is dated and public, which makes it one of the earliest honest signals that money is about to be spent on a property — often well before a sale would show it, and it keeps happening even when the sales market itself goes quiet. Behind each row is a sequence of real spend: design and consent work first (architects, chartered surveyors, structural engineers), then the build itself (builders, electricians, plumbers), and — as work gets underway — windows, kitchens, bathrooms, flooring and landscaping, plus the finance and insurance that go with a project of that size. If you're one of those trades, the table below is close to a live map of where that work is actually happening on the island right now, by type and by how often it gets approved. This site's own professional directory currently covers architects, chartered surveyors, mortgage brokers, banks & lenders, structural engineers, builders, insurance brokers, plumbers and electricians — plus honest empty entries for quantity surveyors, windows, kitchens, bathrooms, flooring and landscaping, where a real research pass found no genuine Jersey-specific category to build — see Professionals.

Classified automatically from each application's own description text — a minority will sit in a category a human reader would classify differently. "Approved" is over that type's decided applications only (see the full type-vs-outcome breakdown). The directory link under a row's name goes to the professional category most directly involved in that type of work — not every category has one yet.
