Step 3: Update the national brownfield land register

The Ministry of Housing, Communities and Local Government (MHCLG) will maintain a national brownfield land register, using the data you publish.

Email the URL you created in step 2 to and we will add them to the national register.

You will soon be able to submit the URL through an online tool the Digital Land team are developing. When this is ready, the team will make an announcement on the Digital Land blog and this guidance will be updated.

We also recommend that you add the URL to
