Marine Management Organisation
Use the marine licence interactive assistance tool to find out:
- If your activity falls within the jurisdiction of the MMO
- If an exemption may apply (where appropriate)
- If your activity is suitable for self-service marine licensing (where appropriate)
Overview
Many activities that take place in and around the sea require a marine licence. It is your responsibility to find out whether your activity requires a marine licence. This will usually depend on:
- Where the activity will take place
- What the activity is
- How the activity will be carried out
Jurisdiction
The Marine and Coastal Access Act 2009 provides that a marine licence is required for certain activities carried out within the UK marine area.
The MMO is responsible for marine licensing in English waters and for Northern Ireland offshore waters.
The MMO is also responsible for marine licensing of some activities in other parts of the world.

Activities that may need a marine licence
There are seven categories of activity that may need a marine licence. Follow the links below to find out more about the activities and the circumstances in which they may need a marine licence:
- Construction (including laying of cables, maintenance, alteration or improvement of existing structures and assets)
- Dredging
- Deposit of any substance or object
- Removal of any substance or object
- Incineration of any substance or object
- Scuttling (sinking) of any vessel or floating container
- Use of explosives
Exemptions
Exemptions provide proportionate regulation of the marine environment. They remove the need for a marine licence for certain activities in certain circumstances.
If you intend to rely on an exemption you must make sure that you meet the relevant qualifying criteria and conditions. You might also need to notify the MMO about your activities.
Enforcement action may be taken if it is later determined that the activity, or the circumstances in which it was carried out, is not consistent with the terms of the relevant exemption.
Use the marine licence interactive assistance tool to check whether an exemption applies or notify the MMO of the intention to carry out an exempt activity.

Self-service
The MMO classes a number of activities as low risk because they are sufficiently consistent in nature and extent. Self-service marine licensing provides a mechanism for those seeking to carry out these activities, to obtain a marine licence without being subject to the standard marine licensing process.
Use the marine licence interactive assistance tool to check whether your activity is one that is suitable for self-service marine licensing or to apply for a self-service marine licence.

Standard marine licence
If a proposed activity requires a marine licence and the activity is not one that meets with self-service criteria, a standard marine licence will be required.
You can apply for a standard marine licence online.

Other consents
You should note that activities in and around the marine environment may also require additional consents, irrespective of whether they need a marine licence or not.
A wildlife licence may be required if the proposed activity could impact a protected species or habitat. This can include disturbance, injury, killing, collection, damage or destruction of place or structure that is used for shelter or protection and preventing access to such a place or structure. Further information on when a wildlife licence is required can be found here.
A seabed survey licence or coastal survey licence will be required from The Crown Estate for survey activities that physically interact with the foreshore (including estuarine) or seabed under ownership of The Crown Estate. Other projects, such as habitat restoration, will also require a licence from The Crown Estate if it impacts upon the foreshore or seabed that they manage. A map of The Crown Estates foreshore and estuary ownership is available on their Open Data Portal.
Works taking place partly on land often require planning permission from the local planning authority.
If there is a discharge of some kind or abstractions of water an environmental permit or water abstraction licence from the Environment Agency may be needed.
Sites of Special Scientific interest (SSSI) consent from Natural England may be required for activities taking place within SSSIs.
