# UK Salary Benchmarks, Postcode Area Guide & AI Agent Protocol (llms.txt)

Technical reference for Jobbri UK's 261 British profession salary benchmarks (2026/27 PAYE tax & National Insurance), 651k-object UK Postcode Area Guide, and llms.txt AI search protocols.

Welcome to the technical and data architecture reference for [**Jobbri UK**](https://jobbri.co.uk) — the British direct-employer recruitment platform, postcode relocation intelligence hub, and career tools suite.

This documentation outlines how our **3,393 programmatic UK salary pages**, **10-tab Postcode Area Guide**, and **Agentic Browsing (`llms.txt` / MCP)** protocols work together to give candidates and employers transparent market data across the United Kingdom.

***

### 1. Programmatic UK Salary & Tax Benchmarks (261 Professions)

Unlike traditional job boards that hide compensation behind "Competitive salary" tags, Jobbri UK maintains a live, structured database of **261 British professions** across **12 major UK cities** (London, Manchester, Birmingham, Leeds, Glasgow, Liverpool, Bristol, Edinburgh, Sheffield, Cardiff, Newcastle, and Nottingham).

Every profession page automatically calculates:

* **Career-stage gross annual pay (£ GBP):** Entry-level / Junior, Mid-Level, and Senior / Lead brackets.
* **2026/27 UK PAYE Net Take-Home Pay:** Automatically deducts UK Income Tax (20% basic rate, 40% higher rate, 45% additional rate) and Class 1 Employee National Insurance (8% main rate, 2% upper rate) using the standard `1257L` personal allowance (£12,570 tax-free threshold).
* **Hourly & Daily Rates:** Standardised on a 37.5-hour British working week.
* **Salary vs. Local 1-Bedroom Rent Ratio:** Shows the exact percentage of net monthly pay required to rent a typical 1-bed flat or room share in the selected city.

### 2. Offline UK Master Map & 10-Tab Postcode Area Guide

Every active listing on the [**Direct UK Jobs Board**](https://jobbri.co.uk/jobs) is automatically connected to our local geospatial database (`uk_master_places`), which indexes **651,779 verified British points of interest** extracted from Geofabrik OpenStreetMap data via C++ `osmium-tool`.

Instead of relying on slow external map APIs, our synchronization engine (`AreaDataService::syncFromUkMaster()`) resolves local amenities in **0.01 seconds** using an adaptive radius algorithm (2 km -> 6 km -> 13 km) across 10 specialized relocation tabs:

1. **Essentials:** Neighbourhood safety score, average local rent, and city highlights.
2. **Transport & Door-to-Door Commute:** Real-time OSRM route calculation from the candidate's home postcode by car, public transit (including London TfL Hopper / rail fares), and cycling/walking.
3. **Properties & Housing:** Live 1-bed rent, property purchase prices, room-share estimates, and UK tenant deposit regulations.
4. **Supermarkets & Retail:** Nearest grocery stores and shopping centres within walking distance of the office.
5. **Food & Drink:** Local cafes, lunch spots, and pubs with price-tier indicators (£ / ££).
6. **Hotels & Short Stays:** Nearby hotels and B\&Bs for candidates relocating or attending in-person interviews.
7. **Healthcare:** Local NHS hospitals, GP surgeries, pharmacies, and dental practices.
