Mid-market insurance
Harbour authority insurance is the programme of liability, property, marine and management covers that a statutory or trust harbour authority buys to protect its estate, operations and board. It matters because one grounding, spill or pontoon failure can test several policies at once.
Part of: Marine trades insurance
In short
Harbour authorities need a programme built around port and marine liability, not a standard commercial package. The core is liability for conservancy, navigation and pilotage functions, plus property and income cover for quays and pontoons, hull and liability for owned craft, pollution cover, employers’ liability and D&O for the board. The Ports and Marine Facilities Safety Code, updated in April 2025, makes the board accountable for marine safety, and insurers usually expect to see evidence of compliance, structure inspections and spill planning.
A statutory or trust harbour authority usually needs a combined programme rather than a single policy: port and harbour liability (including its liability as a navigation and conservancy body), property and business interruption for quays, pontoons, buildings and equipment, hull and liability cover for its own workboats and pilot launches, pollution cover, employers' liability, and management liability for the board. Many authorities also need motor fleet, cyber and terrorism cover.
What sets a harbour authority apart from an ordinary property owner is that it holds statutory powers and duties. It directs vessel movements, may provide or authorise pilotage, maintains channels and aids to navigation, and can remove wrecks. When any of those functions goes wrong, the claim is often against the authority itself, and an ordinary public liability policy may not respond to marine losses. That is why the core of the programme is usually a specialist marine liability policy written around port operations.
| Exposure | Typical example | Cover that usually responds |
|---|---|---|
| Damage to quays, pontoons, cranes, buildings | Storm surge lifts pontoon sections; vessel strikes a quay wall | Property or commercial combined, with marine structures declared and valued |
| Loss of dues and income | Berth closed after quay damage; channel closed after a sinking | Business interruption or loss of revenue, ideally with extensions for denial of access |
| Liability as harbour and conservancy authority | Alleged failure to mark a hazard or maintain a channel | Port or harbour authority liability (marine liability) |
| Pilotage and marine services | Vessel damaged during an act of pilotage or towage | Marine liability, subject to the terms of the authority’s pilotage and service conditions |
| Pollution | Fuel spill from a berthed vessel or the authority’s own bunkering | Marine pollution cover, plus any sudden and accidental pollution in liability |
| Owned workboats and pilot launches | Launch grounds or collides | Hull and machinery plus protection and indemnity or a liability extension |
| Injury to staff, lock keepers, boat crews | Fall between quay and vessel | Employers’ liability |
| Wreck removal | Abandoned vessel sinks in the harbour | Marine liability or wreck removal extension, where included |
| Board and trustee decisions | Challenge to a board decision or an investigation after a fatality | Directors’ and officers’ or management liability |
| Port systems and data | Ransomware locks berth booking or CCTV | Cyber cover |
| Vehicles and plant on the estate | Port vehicle damages a third party car | Motor fleet; see our fleet guide |
Ports and Marine Facilities Safety Code. The code formerly known as the Port Marine Safety Code was updated by the Department for Transport in April 2025 and is now published as the Ports and Marine Facilities Safety Code. It sets out a national standard for marine safety. The board (the duty holder) is accountable for marine safety and cannot delegate that accountability. A designated person gives the board independent assurance that the marine safety management system works. The code expects a formal risk assessment, a safety management system built on it, regular review and audit, a published marine safety plan, and a compliance statement to the Maritime and Coastguard Agency every three years. Compliance is voluntary in law, but the code reflects good practice and a failure to follow it may be relied on in a prosecution under health and safety or other legislation. The MCA ran a compliance exercise inviting ports and marine facilities to submit compliance up to 31 March 2026.
Pilotage. Under the Pilotage Act 1987 a competent harbour authority must assess what pilotage services are needed for safety and, if pilotage is to be compulsory, issue pilotage directions. Liability for pilotage acts is shaped by the Act and by the authority's own conditions, so the liability wording should be read against both.
Limitation. Under section 191 of the Merchant Shipping Act 1995, harbour authorities, conservancy authorities and dock and canal owners can, in some circumstances, limit their liability for loss or damage to a ship or goods on board by reference to the tonnage of the largest UK ship in their area in the previous five years. Limitation helps, but it does not replace a properly set limit of indemnity.
Pollution and dangerous goods. Harbour authorities may need an oil spill contingency plan under the Merchant Shipping (Oil Pollution Preparedness, Response and Co-operation Convention) Regulations 1998, and the Dangerous Goods in Harbour Areas Regulations 2016 require emergency plans. Harbour authorities also have environmental duties under section 48A of the Harbours Act 1964.
Employers' liability. The Employers’ Liability (Compulsory Insurance) Regulations 1998 set a minimum of £5 million for any one occurrence. Many harbour authorities buy higher limits given the severity of marine injuries.
These are illustrative scenarios, not real claims.
A trust port's visitor pontoon breaks free in a storm and damages moored yachts. The property section usually responds to the pontoon itself if marine structures were declared; the yacht owners' claims are tested against the liability wording, which may turn on whether the authority's inspection regime was reasonable. Lost berthing income falls to business interruption.
A coaster grounds and alleges a buoy was off station. The claim is against the authority in its conservancy role. Port liability usually responds, subject to limitation and the policy terms, and the authority's PMSC records become key evidence.
A pilot is hurt boarding from the authority's launch. Employers' liability responds if the pilot is an employee; if the pilot is self employed, the claim may fall under liability or the launch's P&I cover instead. Getting the employment status right before a loss matters.
A strong submission for a harbour authority usually includes:
A review is worth doing when the authority takes on new berths or pontoons, starts handling larger vessels or new cargoes, brings pilotage or towage in house, adds commercial property or leisure facilities, or completes a PMSC audit that changes its risk assessment. Growing ports often add a marina, which brings exposures covered in our marina and boatyard insurance guide. Our insurance programme review checks every policy against your actual operations, and the marine trades insurance hub covers the wider sector. For background, see our explainer on marine insurance.

The code, now published as the Ports and Marine Facilities Safety Code, is not statutory and creates no new legal duties. It reflects good practice, and a failure to follow it may be relied on in a prosecution under health and safety or other legislation. Insurers often ask for evidence of compliance when assessing a harbour authority.
Usually not on its own. Standard public liability wordings commonly exclude or restrict liability arising from watercraft and marine operations. A harbour authority normally needs a marine or port liability policy that covers its conservancy, navigation and pilotage functions, subject to the policy terms.
In some circumstances, yes. Section 191 of the Merchant Shipping Act 1995 lets harbour authorities, conservancy authorities and dock and canal owners limit liability for loss or damage to a ship or goods on board, calculated by reference to the tonnage of the largest UK ship in their area in the previous five years.
It is commonly bought. Board members of trust ports and statutory authorities are accountable as duty holder under the safety code and can face investigations or claims after serious incidents. Directors' and officers' cover can meet defence costs and some liabilities, subject to the policy terms and exclusions.
The legal minimum under the Employers' Liability (Compulsory Insurance) Regulations 1998 is £5 million for any one occurrence. Many harbour authorities buy more because marine injuries can be severe. Check whether pilots and boat crews are employees or contractors, as this affects which policy responds.
