# PlanningLedger

> PlanningLedger is building planning superintelligence: one mind that knows
> and understands everything about planning in the UK.

Today it reads the UK planning record: planning applications and their
documents, decisions, appeal decisions and Local Plan policies for councils
across England, Scotland, Wales and Northern Ireland, each linked to the
council's own copy.

- For AI assistants: the PlanningLedger connector (https://mcp.planningledger.com/,
  listed in Claude's connector directory at
  https://claude.ai/directory/connectors/planningledger) serves that UK-wide
  record to Claude and other assistants that support MCP connectors.
- The Reading Room (readingroom.planningledger.com): ask a question about
  anywhere in the UK in plain English, get a cited research memo by email; free
  during the limited release, limits apply.
- For London: borough figures, league tables and a free address constraint
  check.

## Data pages

- /boroughs — index of London borough planning statistics
- /boroughs/<borough-slug> — per-borough approval rates, decision speeds, volumes
- /league-tables — ranked London borough league tables (approval rate, decision
  speed, householder approvals), updated monthly
- /methodology — metric definitions, statutory targets, insufficient-data rules
- /guides — evergreen planning guides (permitted development, conservation areas, application timelines)

All figures carry a snapshot period and computation date. Metrics with fewer
than 20 decisions in the window are reported as insufficient rather than ranked.

## What PlanningLedger offers

- The connector for AI assistants — read-only tools for planning applications,
  documents, decision counts, appeals and Local Plan policies across the UK, at
  https://mcp.planningledger.com/.
- The Reading Room — ask a question about UK planning decisions; a research
  memo comes back by email with references to the council's and the appeal
  bodies' own records. How much of the record we hold varies by council; each
  memo says how much of it could be searched for the place asked about. Answers are drafted by an AI research agent that
  works only from our copy of the planning record, and every reference is
  checked against those records before the memo is sent.
- Borough figures and league tables — approval rates, decision speeds and
  volumes for the 33 London planning authorities.
- A free address constraint check (conservation areas, listed buildings, Article
  4 directions and similar designations for one address).
- The Weekly Approvals Digest — a free weekly email of the week's notable London
  approvals, borough by borough. It is a weekly newsletter, not a real-time alert
  service.

## What PlanningLedger is not

- Not a directory of planning consultants, architects or companies, and it does
  not match firms with work.
- Not connected with The Planning Review (theplanningreview.co.uk), which is a
  separate business with its own consultant directory and application alerts.
- Not legal, viability or structural advice.
- The address check, borough figures and league tables cover London only
  today; the connector for AI assistants and the Reading Room cover the UK.
