Apply to lay cables

Laying telecommunications and power cables within UK territorial waters (up to 12 nautical miles) requires a marine licence.

Laying telecommunications and power cables within UK territorial waters (up to 12 nautical miles) requires a marine licence. If the cable is an international cable, MMO are obliged to grant the marine licence, but can include conditions.

Laying international cables outside UK territorial waters (beyond 12 nautical miles) does not require a marine licence. However, associated works, such as pre-lay dredge and disposal and cable protection works may require a marine licence.

A marine licence is required for the laying of all cables used in connection with:

  • exploring the UK sector of the continental shelf
  • exploiting the natural resources of that sector
  • operating artificial islands, installations and structures under the jurisdiction of the UK
  • preventing, reducing or controlling pollution from pipelines

MMO cannot grant a marine licence for works within non-Crown-owned tidal sea beds unless it is satisfied that adequate arrangements have been made to compensate owners of interests in the tidal water or lands affected for any loss or damage.

Trans-European Networks – Energy (TEN-E)

The European Commission can designate energy infrastructure projects, including international cable developments, as a project of common interest (PCI) under the TEN-E Regulation.

However, The TEN-E regulation is being revoked when the UK leaves the EU exit by article 152(1) and Schedule 3 of the Electricity and Gas etc. (Amendment etc.) (EU Exit) Regulations 2019. The revocation will be subject to some saving provisions for projects which have already received planning permission in the UK.
