Explainer · last look 16 September 2026 Felixstowe vs Immingham — which door the box actually uses Britain does not have one port. It has jobs. Felixstowe lifts steel boxes from Asia — sofas, toys, phones. Immingham pumps tonnes — diesel, jet, pellets, ore, and North Sea trailers. Weigh the country and Immingham with Grimsby is huge. Count the Christmas aisle and Felixstowe is the door. Mix them and you wait for the wrong ship. |
If you remember one sentence: a late sofa is Felixstowe. Dearer diesel is Immingham.
How fast does each door matter?
|
Days Immingham fuel. A product tanker is a 1–14 day clock. Hormuz shows up here as a price, not as a missing sofa. |
3–6 weeks Felixstowe boxes. China on the Cape is 43–47 sea days. If it has not left by early October it is not a mid-December parcel. |
This peak The next six weeks are the stack. Felixstowe and London Gateway share the aisle. Immingham shares the tank. |
A 14-year-old version: two school gates. One is for the lunch boxes. One is for the heating oil lorry. You do not stand at the oil gate waiting for your sandwiches.
Weigh the country, then count the aisle
DfT weighs ports in tonnes. That ranking makes Immingham look like the giant and Felixstowe look mid-table. Both statements can be true.
| UK major ports, 2024 tonnes | Million tonnes | Share | Job in one word |
|---|---|---|---|
| London (whole cluster) | 51.9 | 12.1% | Mix — and Gateway boxes |
| Grimsby & Immingham | 43.7 | 10.2% | Fuel, bulk, Ro-Ro |
| Southampton | 33.3 | 7.7% | Boxes and cars |
| Milford Haven | 32.9 | 7.7% | Energy |
| Liverpool | 31.3 | 7.3% | Mix |
| Felixstowe | 23.1 | 5.4% | Boxes |
Source: DfT port freight annual 2024. Major ports 421.0 million tonnes. All UK ports 429.7 million — lowest in the series since 2000. Felixstowe is seventh by weight and first by the shop.
| 421 Mt major ports 2024 |
163 Mt liquid bulk — biggest group |
61 Mt containers by weight |
~32% Felixstowe share of container tonnes |
Liquid bulk is the fat slice of the weighbridge. Containers are a thinner slice of tonnes and a fat slice of the high street. That is why “busiest port” is a trick question. Ask: busiest at what?
What each door actually unpacks
| Felixstowe | Immingham (with Grimsby in DfT) | |
|---|---|---|
| Water | Suffolk, North Sea | Humber |
| Owner | Hutchison Ports UK | ABP (Killingholme: CLdN) |
| Main cargo | Lift-on, lift-off containers from Asia | Oil products, dry bulk, biomass, Ro-Ro |
| 2024 weight | 23.1 Mt | 43.7 Mt |
| 2025 boxes | Historic lead door; ~3.6m TEU in 2024 official set | Feeder boxes only — not the Asia giant |
| Import value logged 2025 | About $41bn through Felixstowe | Humber group: energy and industry, not the toy aisle |
| Inland | Heavy rail — port says ~1m TEU/year, ~58 trains a day | ABP: 240+ rail freight movements a week; DFDS Ro-Ro to North Europe |
| You feel a delay as | Empty shelf, late sofa, missed Christmas cut-off | Dearer diesel, heating oil, pellets |
Immingham does handle some containers. They are mostly short-sea feeders. The 400-metre Asia ship with 20,000 boxes does not pick the Humber for that job. It picks Felixstowe, London Gateway or Southampton. Three ports took about 94% of UK deep-sea container traffic in 2024.
The box family — Felixstowe is not alone
| Door | 2025 habit | If your booking moves here |
|---|---|---|
| Felixstowe | Classic China call. Q1 2026 units −16% as some loops left. | Midlands and North often like the rail. |
| London Gateway | Fourth berth. About 3 million containers in 2025. Q1 2026 London units +19%. | Shorter lorry to London warehouses. Same sea days. |
| Southampton | 2 million+ TEU. Also the car port — 480,000 vehicles in 2024. | South and West. Same Cape or Suez choice. |
A loop that leaves Felixstowe for Gateway is not a vanished sofa. It is a different quay. Add days only if the ocean road changed — Suez to Cape — or the berth window was missed. That lecture lives on why a UK Christmas parcel is already late in September.
What 2025–26 did to each weighbridge
| Quarter | Felixstowe / boxes | Grimsby & Immingham / tonnes |
|---|---|---|
| Q4 2025 | UK container tonnes +19%. London +52% after Gateway’s fourth berth. | Liquid bulk −43% (about 1.9 Mt). Dry bulk +46%. |
| Q1 2026 | Felixstowe container tonnes −17%; units −16%. Some cargo changed quay, not country. | Liquid bulk −45% (2.1 Mt) — Lindsey refinery closed 2025. Dry bulk +45%. |
| Q2 2026 | Felixstowe tonnage 5.7 Mt (CEIC / DfT quarterly). | 10.6 Mt — still roughly double Felixstowe by weight. |
Lindsey shutting is why Immingham’s liquid-bulk line fell. The Humber did not stop being an energy door. Dry bulk and product imports filled part of the hole. Read that as a mix shift, not a closed gate.
Which cargo, which door?
| If the thing is | Stand at |
|---|---|
| A China box — clothes, toys, phones, furniture | Felixstowe, London Gateway or Southampton |
| Diesel, jet, heating oil, wood pellets, ore | Immingham (and other energy doors: Milford Haven, London) |
| A trailer from Rotterdam or Gothenburg | Immingham Ro-Ro — or Dover if it is the short Channel hop |
| A new car from Asia or Europe | Southampton first; not Felixstowe’s main job |
| Grain in bulk | Humber bulk — start the map at the Black Sea, not Shenzhen |
What should a buyer do with this?
| If you | Ask |
|---|---|
| Sell the aisle | Which of the three box doors is on the bill of lading? Sea days first. Quay second. |
| Buy fuel or pellets | Is the cargo on the Humber? Then the clock is days, not the Cape. |
| Read “UK ports delayed” | Delayed at which door, for which cargo? One headline cannot cover both. |
| Have a late sofa and a dear tank | Those are two stories. This page and the heating-oil page. Not one queue. |
The short answer
Felixstowe is the box door. Immingham is the tonne door. Weigh Britain and the Humber with Grimsby is second only to London. Count the Christmas aisle and Felixstowe — with Gateway and Southampton — is the set that matters. A ship can be on time at one gate and irrelevant at the other. Name the cargo before you name the port.
