See what LandLens™ can do

A walkthrough of the planning constraint map and developer API — the two core tools that give property professionals instant access to planning intelligence for any UK postcode.

The Constraint Map

Interactive planning intelligence for any UK postcode

What it does

The constraint map is the heart of LandLens. Enter any UK postcode and instantly see every planning constraint that affects that site — flood zones, conservation areas, green belt, listed buildings, Article 4 directions, brownfield designations, and more. All data is sourced live from official government APIs, not cached downloads.

Each constraint layer renders as a colour-coded polygon overlay on the map, with a structured results panel showing what applies, what doesn’t, and the source of every data point. You can toggle layers individually, adjust the map view, and export the entire assessment as a branded PDF.

How it works

1

Enter a postcode

Type any UK postcode into the search bar. The map centres on the location instantly.

2

Toggle data layers

Switch on the layers you need — flood zones, conservation areas, green belt, listed buildings, and more. Each layer renders as a colour-coded overlay.

3

Review constraints

The constraint panel shows every active designation for that location — with source data, distances, and severity ratings.

4

Export a report

Download a branded PDF site report with all constraints, map screenshot, and data citations — ready to attach to a client email or board pack.

  • ✗ 30–45 minutes per site assessment
  • ✗ Risk of missing a constraint

With LandLens

  • One search, all 14 layers at once
  • Results in under 10 seconds
  • Exportable branded PDF report
  • Every data source cited

The Developer API

Programmatic access to UK planning data via REST endpoints

LandLens API documentation showing endpoint definitions and JSON response examples

What it does

The LandLens REST API gives you programmatic access to every dataset available on the platform. Query planning constraints, flood zones, EPC data, price paid records, corporate ownership, and planning applications — all authenticated with dedicated API keys, rate-limited per key, with full usage analytics in your admin dashboard.

Build integrations into your existing tools, automate portfolio screening, power internal dashboards, or feed constraint data into your own site appraisal workflows. Every response returns structured JSON with full data provenance.

Dedicated API Keys

Each team gets unique keys with independent rate limits and usage tracking.

Real-Time Data

Every response queries live government APIs — no stale cached datasets.

Usage Analytics

Full dashboard showing call volumes, response times, and error rates.
