Check if your land is in an NVZ

Use the interactive map to find out if your land is in an NVZ. The map has now been updated to reflect the outcomes of NVZ appeals for 2025-2028.

Your farm may be completely or partly in an NVZ. NVZ boundaries are drawn around whole fields, so there are no fields that are only partly in an NVZ.

Restrictions apply to each field that’s in an NVZ.

Email the Environment Agency at enquiries@environment-agency.gov.uk if you have difficulty checking online or need a printed map.

How to appeal

The guidance below explains how to appeal if you are notified that you fall within an NVZ.

You will receive a letter from Defra, if your land is within an NVZ. You can appeal against the decision within 28 days of the date on the letter.

You have grounds to appeal if your land (or part of it):

• does not drain into water that has been identified as polluted
• drains into water that should not be identified as polluted
