Understand marine wildlife licences and report an incident

Why you need a marine wildlife licence if you are going to disturb a protected species, how to apply and how to report an incident.

Marine wildlife licences

You must have a marine wildlife licence if you want to carry out an activity that would affect a UK or European protected species.

The Marine Management Organisation (MMO) licenses activity in English waters and Welsh offshore waters, Natural Resources Wales licenses activity in Welsh inshore waters, and Scottish Natural Heritage and Marine Scotland (for seals) license activity in Scottish waters.

Call us on 0300 123 1032 or email before you start you activities if you are uncertain if you need a wildlife licence or whether your activities may disturb a protected species, result in an offence, or both.

You can apply online using the marine licensing online application system.

Your application will take about 6 weeks to process. This includes consulting with Natural England, the Joint Nature Conservation Committee, or both, depending on where your activity is located.


You must have a wildlife licence if you are diving and intending to do something likely to disturb seahorses. This could be taking photographs, filming or surveys. Both seahorse species found in UK waters –spiny (Hippocampus guttulatus) and short-snouted (Hippocampus hippocampus) – are protected. Intentionally disturbing seahorses in the absence of a wildlife licence could lead to enforcement action.

MMO will consider applications for licences for scientific or education purposes to allow seahorses to be photographed using flash photography on a case-by-case basis. An independent scientific review concluded that flash photography at high levels can disturb seahorses, especially when combined with other activities. It may be possible to reduce the effects using conditions on licences issued. MMO will update their advice if new evidence and scientific knowledge becomes available.

MMO recommends following diver protocols to reduce the likelihood of committing an offence as a result of incidental encounters with seahorses. See the divers’ protocol (available from Dorset Wildlife Trust or The Seahorse Trust) for seahorses and sea grass and the Wildlife Safe (WiSe) guidelines for taking part in research or filming (PDF, 58KB, 3 pages) .
