Getting started

Foundry Compliance checks building design parameters against England Part L 2021 (Approved Document L) and the Future Homes Standard 2025. Welsh projects are checked against Approved Document L (Wales) 2022. This tool covers England and Wales only — it does not cover Scottish or Northern Irish building regulations. Upload your design pack PDF or enter parameters manually to receive an instant compliance check.

How to run a compliance check

• Log in to your account at foundrycompliance.co.uk.
• Upload your design pack PDF or enter parameters (U-values, heating system, glazing ratios) directly.
• Review the extracted values — correct any that were misread before proceeding.
• Submit the check and review your compliance report, including any failed clauses and recommendations.

Understanding your results

Each finding includes a reference to the specific Part L or FHS clause it checks against, the value we found in your submission, and the required value. A result of "Pass" means your submitted value meets the requirement — it does not constitute a building control approval. Results must be reviewed by a qualified professional before submission to building control.

Common questions

• What file types can I upload? PDF files only, up to 25 MB.
• What documents should I upload? Upload design-stage documents — the kind an architect has at RIBA Stage 2–3, before planning submission or early building regs:
  • Architectural drawings (floor plans, sections, elevations, roof plans, site plans)
  • Site plan / location plan / block plan
  • Outline specification / specification notes
  • Design and Access Statement
  • Building Control application documents (full plans or building notice)

  Do not upload SAP calculations, thermal bridging assessments, or Energy Performance Certificates — these are produced after design is complete. If you have them, you are past the stage this product is designed for. Photographs are not accepted; PDF files only.

• What standards are covered? Approved Document L 2021 (England) and Future Homes Standard 2025. Wales jurisdiction checks use Approved Document L (Wales) 2022 and are advisory.
• Can I export my results? Yes — use the Export button on the results page to download a PDF report.
• How do I cancel my subscription? Go to Account → Subscription and select Cancel. Your data remains accessible until the end of your billing period.
• How do I delete my account? Go to Account → Delete Account. This permanently erases all your data and cannot be reversed.
