Submitting a SNIN

Please submit your SNIN form as far in advance of starting work on site as possible but at the latest:

Standard, non-hazardous sites: 4 weeks before start date

Hazardous or non-traditional sites: 8 weeks before start date

You can submit a SNIN form to NHBC, in the following ways:

Email:​​​​ To SNINEnquiries@nhbc.co.uk

My NHBC Portal: From your organisation home page, select "Add new site" or by selecting "Upload organisation documents"

Post: To NHBC House, Davy Avenue, Knowlhill, Milton Keynes, Bucks, MK5 8FP.

What happens next?

Step 1 We’ll process your SNIN form and generate a site reference number
