UK & Ireland Port Congestion Report

Published 18 September 2026 · Sources rechecked 18 September 2026 at 15:05 BST · Coverage: 17 ports · Last verified port-wide numerical measurement: unknown

Operational advisory, not a numerical congestion ranking

No comparable, timestamped primary measurement was verified this week for port-wide waiting times, vessel queues, berth utilisation or congestion scores. Unknown does not mean normal: it means the evidence needed to calculate a defensible ranking was unavailable.

Weekly evidence summary

Liverpool’s official notice page still lists local dock, bridge and lock notices. The Canada 90-foot Swing Bridge and Alfred Lock notices had time-limited windows that ended before this report was published; the source does not confirm actual reopening, so operators should verify locally. Royal Seaforth S7/S8 and the South Gladstone south quay remain within their stated closure periods. Dublin Port continues to list maintenance dredging and survey work. Met Office marine forecasts issued on 18 September carry Irish Sea and nearby coastal gale or strong-wind conditions. These are operational constraints and weather context—not measurements of port-wide congestion.

LiverpoolNotices 55 and 57 remain within their stated closure periods: Royal Seaforth S7/part S8 through 29 September and South Gladstone south quay through 27 September. Notices 62 and 63 describe time-limited bridge/lock windows that have now ended; no reopening confirmation or port-wide waiting time was found.Peel Ports index rechecked 18 September at 15:05 BST.Confirm vessel movement route, berth availability, lock/bridge access and terminal collection slot with the carrier, terminal or Dockmaster.
DublinNotice 48 says maintenance dredging began 3 September for approximately three weeks. Notice 39.3 schedules survey work from 13 September, but two public copies conflict on the approximate end date.Dublin Port notice index rechecked 18 September at 15:05 BST.Ask Dublin Port VTS or the carrier which work area applies, whether manoeuvring restrictions affect the call and which survey end date is current.
Irish Sea / HolyheadThe shipping forecast issued 10:30 UTC retains an Irish Sea gale warning and forecasts southwest force 5–7, occasionally gale 8 at first, easing later. This does not establish a delay at Holyhead.Forecast valid 12:00 UTC 18 September to 12:00 UTC 19 September.Check the operator’s live sailing notice and terminal cut-off before dispatching a driver.
Belfast / LarneThe inshore forecast issued 12:00 UTC lists strong winds for Lough Foyle to Carlingford Lough and the Firth of Clyde/North Channel. No port-specific queue or waiting-time measurement was verified.Forecast valid 12:00 UTC 18 September to 12:00 UTC 19 September.Confirm sailing status, accompanied/unaccompanied cut-off and collection appointment directly with the operator.
Other 12 covered portsNo current, comparable port-wide queue, waiting-time or berth-utilisation measurement was verified. Conditions are therefore unknown, not zero or normal.Evidence ledger reviewed 18 September.Use the 17-port tracker for source coverage and confirm shipment-specific conditions before routing.

What changed over the past seven days

No numerical week-on-week congestion change is calculated because there are no comparable verified port-wide measurements for either week.

Primary evidence

Questions to ask before booking or collection

  1. Has the vessel schedule or terminal cut-off changed since the booking confirmation?
  2. Does a lock, bridge, dredging or survey notice affect this vessel, berth or collection route?
  3. Is a vehicle appointment required, and is the slot still confirmed?
  4. Are customs release, port health or transit documents complete before dispatch?
  5. When does free time begin, and who bears demurrage, detention or storage if the plan changes?

Methodology and limitations

Carrgo reviews dated public primary sources and records each supported claim at the narrowest defensible level. Port or terminal notices support only the location and period they name. Weather forecasts describe sea or coastal areas and are not treated as evidence of terminal queues. Carrgo does not currently use a verified AIS feed and does not calculate a numerical congestion, health, queue or berth-utilisation score without traceable measurements and a reproducible method. Missing values remain unknown. Advice is separated from facts, and users should confirm time-sensitive arrangements with the relevant carrier, terminal, port or VTS.
