We aim to process your application within 13 weeks from the date you accept our fee estimate for your application (excluding on hold time).

After you accept the fee estimate we鈥檒l allocate your application to a case team. A case officer will contact you by email to confirm this.

It is not unusual for an application to be given an 鈥榦n hold鈥� status once the case team start processing your application. This is usually because we need further information from you.

For a standard marine licence we will always consult our primary advisors and undertake a public consultation. We may also decide to consult interested parties about your application. This usually includes other public authorities and agencies. If we do this, we may contact you to place notices in national and local publications as part of your application process and request further information. The consultation may also lead to requests for further information from you.

When the case team has finished processing your application, we鈥檒l either:听

  • grant the marine licence听
  • grant the marine licence subject to conditions听
  • reject your marine licence application听

In case we apply conditions to your license or refuse your application, we鈥檒l set out a record of reasons.

After you receive an application decision听

During the marine licence application process the MMO will send the draft marine licence for you to review.

You may then be required to fulfil conditions associated with your licence on our听, for example, provide any updated versions of documents required before you can start the activity.听The MMO will review this document and confirm if it is sufficient to discharge the condition.

Some conditions may only be able to be actioned once the activity is happening. For example, noise reports for piling activities. Others may only be able to be actioned after the activity has been completed. For example, assessments on mitigation measures.听

Any post-consent monitoring completed by the MMO of your marine licence, which includes any reviews or approvals which are required, may incur a fee. Read more about our fees.听

Appeals听

听You can appeal our decision if:听

  • we refused to grant you a marine licence听
  • you disagree with the conditions attached to your marine licence听
  • you disagree with the length of time your marine licence has been granted for听

In England appeals are heard by the Planning Inspectorate (PINS) on behalf of the Secretary of State. Only you as the applicant can appeal a decision. However, a challenge in the courts by judicial review may be available to a third party.听

You have 6 months from the date of our decision being made to notify鈥疨INS鈥痶hat you want to make a formal appeal stating your preferred procedure. The available procedures are:听

  • written representations听
  • hearings听
  • inquiries听

We will also be asked to indicate a preferred procedure and鈥疨INS鈥痺ill then decide which will be followed.听听

The start date of the appeal is the date that we receive notification of this decision from PINS.听

PINS鈥痺ill appoint an inspector on behalf of the Secretary of State to consider your appeal.听

There are legal time limits for parts of the procedure that you and鈥疢MO鈥痬ust keep to. This is given in detail in the鈥�

The inspector may dismiss your appeal or allow the appeal and quash our original decision in whole or in part. If our licensing decision is quashed, then we may be directed to grant a marine licence to you or grant a licence subject to conditions defined by the appeal decision.听

An appeal decision can be challenged by judicial review.听

Both sides will normally be expected to pay their own expenses during an appeal. However, the inspector has the power to award costs to any party where a hearing or inquiry is held, or scheduled, but subsequently cancelled at a late stage. There is no provision for costs orders to be made in written representation cases.听

We鈥痚ncourage all outstanding issues or differences of opinion on an application to be resolved during the application process, which may save time and money for all sides if a formal appeal is avoided. If you are unhappy with a potential decision to refuse an application, you can ask the鈥疢MO鈥痶o carry out an internal review of the decision before it is formally issued. To do this, contact [email protected].

Information on how your personal information will be processed for the purpose of marine licensing appeals is published in the鈥�
