List of I-VMS type-approved devices for under-12 metre English vessels
Source: gov.uk (2025-05-11)

Information to support vessel owners and licence holders of under-12 metre English vessels.

Important update – 12 May 2025

A licence condition is now in force, requiring the use of an MMO type-approved I-VMS device on any English under-12m vessel undertaking any trip to sea.

An I-VMS device is a tool that captures the position, course and speed of the vessel. This data will provide valuable insights to the activities of the inshore fleet, and when combined with other data, such as that collected for the over-12m fleet, we will have a more complete picture of all fishing in English waters. This will be used to support decisions and assessments, such as, but not limited to, fisheries management planning, policy development, conservation efforts, statistical and scientific analysis, compliance and law enforcement.

See below for details on MMO type-approved devices and information on the steps to take to purchase and install a device.

Type-approved devices

The following tracking devices have passed the MMO I-VMS type-approval process by meeting the I-VMS device (https://www.gov.uk/guidance/i-vms-type-approval-programme) specification of requirements. All products have undergone evaluation under the I-VMS approval process and are expected to last for at least five years provided they are handled appropriately. All of these products have been designed to be suitable for vessels with or without on-board power.

Fishers should consider the suitability of each device for the vessel and their business, including any warranties, support services, costs and payment plans that suppliers may offer.

Purchase and install a device

You will need a type-approved device installed on your vessel when undertaking any trip to sea from 12 May 2025, or risk being unable to fish legally and possible enforcement action.

Follow the steps below to arrange for the purchase and installation of an MMO type-approved I-VMS device. You can also view and download the buying an I-VMS device step-by-step information sheet (https://assets.publishing.service.gov.uk/media/67e286606e54ea5b2b8ee1c6/Buying_an_I-VMS_device.pdf).

Choose your preferred type-approved device

Review the information above or contact each supplier to decide which device and purchase option is most suitable for your circumstances.

Purchase device from supplier

Once you’ve chosen a device, contact your preferred supplier to purchase and arrange installation.

Install device

Suppliers will provide you with your device, along with details of their approved engineers so you can arrange the installation of your device.

You should not attempt to install your device yourself - any damage or manual interference could void your device warranty.

Read the guidance on operational requirements

Once you have your device, make sure you are familiar with the operational requirements of the licence condition. This includes checking your device, its power supply and data transmissions.
