About s106 Tracker

s106 Tracker is a free, independent database of Section 106 developer contributions across all 337 Local Planning Authorities in England. We collect, standardise, and publish the data that councils are required to report in their Infrastructure Funding Statements — but which is scattered across hundreds of council websites in inconsistent formats.

Why this exists

Developers pay billions of pounds to councils every year under Section 106 of the Town and Country Planning Act 1990. This money is supposed to fund affordable housing, schools, roads, parks, and health facilities. But there is no single place where you can see how much your council has collected, how much it has spent, and how much is sitting in the bank.

We built s106 Tracker to fix that. Every council must publish an Infrastructure Funding Statement each year. We extract the numbers from all of them and present the data in a consistent, comparable, searchable format.

How we collect data

We use three data sources, in order of preference:

  1. planning.data.gov.uk— structured CSV data published by approximately 65 councils that submit to the national platform. This gives us individual agreement-level detail.
  2. Exacom PFM— public-facing modules from councils that use the Exacom developer contributions management system.
  3. PDF extraction— for the remaining councils, we download their IFS PDFs and extract the numbers using a combination of text parsing and AI-assisted extraction, then spot-check for accuracy.
