Where a major development is proposed, you need to submit a Health Impact Assessment (HIA) with your planning application.

The information below provides further details about when an HIA is required, what information this document should include, how to submit it to us, and where you can find further information.

When is a Health Impact Assessment (HIA) required?

An HIA should accompany applications for:

  • residential developments of 10 or more new units
  • developments with 1000m2 or more of additional commercial or visitor floorspace

What information should be included in an HIA?

For major developments of 10 to 99 net dwellings, or 1,000 – 9,999 sqm of additional commercial or visitor floorspace:

For large scale major developments of 100 or more net dwellings, or 10,000sqm or more of additional commercial or visitor floorspace:

  • a comprehensive Health Impact Assessment is likely to be required. You can contact Camden and Islington Public Health through our Development Management team for guidance and advice on the HIA, and the potential health impacts on which to focus. This should be undertaken at the earliest opportunity.

How do I submit an HIA?

If you apply for planning permission online using the Planning Portal, you will be given the opportunity to upload your HIA after you have completed the relevant application forms. Before uploading any files, please read our guidance notes for submitting electronic files with planning applications.
