Full dataset — spreadsheet
Complete dataEvery field, every project, as an Excel workbook. Separate sheets for projects, parties, contracts, tenders, milestones, documents, and more, all linked by project id.
Download full .xlsx →JSON (full data)
The complete record for every project in the OC4IDS standard structure. Best for developers and data pipelines.

A quick summary: one row per project with title, sector, location, budget. Opens in Excel or Google Sheets.

The same one-row-per-project summary as plain text. Good for scripts and quick analysis.
Download .csv →What's inside
The full dataset (spreadsheet or JSON) covers, for every project:
- Project title, sector, location, budget
- The government body that owns the project (the "public authority")
- The supplier that won the work
- Tender details — procurement method, number of tenderers, award value
- Milestones and contract dates
- Any disclosed documents (contracts, inspection reports, feasibility studies)
The two project overview files are a deliberately simpler cut — one row per project with the headline fields — for a fast look or a quick chart. For the complete tabular data, use the full dataset workbook.
All fields follow the global infrastructure-disclosure standard OC4IDS v0.9.5, so the data can be combined with disclosure feeds from other countries.
