When comparing January to March 2022 with January to March 2021 through UK major ports:

• total freight tonnage increased by 7% to 111.8 million tonnes

• inward tonnage increased by 10% to 74.1 million tonnes

• outward tonnage increased by 2% to 37.7 million tonnes

• total volume of unitised traffic increased by 10% to 4.5 million units

• inward units increased by 11% to 2.4 million units

• outward units increased by 8% to 2.1 million units

When comparing the rolling year to March 2022 with March 2021 through UK major ports:

• total tonnage increased by 7% to 446.6 million tonnes

• total volume of unitised traffic increased by 9% to 18.8 million units

Detailed final annual statistics for 2021 will be published in summer 2022. Detailed final annual statistics for 2022 will be published in summer 2023.

Following increases in each quarter of 2021, tonnage traffic through major UK ports has dipped slightly from quarter 4 (October to December) 2021 to quarter 1 (January to March) 2022 consistent with the pre-pandemic seasonal pattern. Quarter 1 (January to March) 2022 tonnage levels are still 7% below what they were in quarter 1 (January to March) 2019. Unitised traffic has also followed the pre-pandemic seasonal pattern, falling by 4% between quarter 4 (October to December) 2021 and quarter 1 (January to March) 2022 and remains substantially below pre-pandemic levels, 20% lower than in quarter 1 (January to March) 2019, reflecting continued lower passenger vehicle numbers. Whilst tonnage and units both increased when comparing quarter 1 (January to March) 2022 with quarter 1 (January to March) 2021, quarter 1 (January to March) 2021 saw the unwinding of stocks after businesses stockpiled in preparation for the end of the transition period with the European Union.

Factors affecting port freight: coronavirus (COVID-19)

These statistics cover a period of government measures introduced to limit the impact and transmission of the coronavirus (COVID-19) pandemic. A quarterly timeline of measures that are relevant to port freight traffic is shown in Further information and definitions at the bottom of this page.

Coronavirus has had a wide impact on UK society and economic activity since March 2020, with travel restrictions impacting unitised traffic particularly, especially passenger vehicles. Sea passenger volumes over this period are published in DfT’s sea passenger data collection and a detailed COVID-19 timeline is available in the monthly table SPAS0107. The 2 sections below aim to provide an exploratory picture of the impact of coronavirus on port freight traffic since 2020.

Quarterly traffic compared to forecasts

DfT’s port freight traffic forecasts were published in 2019 and therefore provide a pre-pandemic estimation of how port freight traffic was expected to evolve.

The different scenarios shown in the port forecasts were based on key economic drivers, namely OBR GDP forecasts, ONS population projections, fuel projections from the OGA, National Grid and BEIS, and EIA Brent price forecasts. These forecasts presented low, central, and high scenarios from 2017 up to 2050.

The impact of coronavirus on port freight can be estimated by comparing port freight traffic statistics since 2020 to the port freight forecasts (adjusted as described in the below note on method). The comparison below shows that all 4 quarters of 2020 were lower than levels expected pre-pandemic, with the lowest point reached in the second quarter of 2020 (April to June).

Note on method:

For past years to 2020, the annual DfT port freight traffic forecasts were adjusted so that the central scenario is in line with published annual port freight figures. Annual figures from 2020 were scaled up based on the average adjustments made to the previous years. The low and high scenarios were then adjusted to keep the same yearly ratio to the central scenario. This is to adjust for the difference observed between actuals and forecasts for the years where the data has become available since forecasts were calculated.

The annual forecasts were broken down into quarters based on the quarterly trend observed in published port freight data in each year for 2017 to 2019. For 2020 onwards, an average quarterly trend over previous years was used to apportion the annual forecast. This is so that the comparison of quarters impacted by coronavirus can be made to the proportion of the annual forecasts we would have expected these quarters to represent.

Passenger vehicle numbers were not included in the port freight forecasts but are included in the quarterly port freight data. Published annual figures for passenger vehicles were added to the forecasts for 2017 to 2019. As a pre-pandemic forecast for 2020 onwards, 2019 passenger vehicles volumes were used. This is because the recent trend for passenger vehicles has been relatively stable (absolute volumes varying between 5.9 and 5.5 million units since 2012).

The above methodology ensures that the baseline used for 2020 onwards to assess the impact of coronavirus on these quarterly statistics has a comparable scope and reflects known trends since the forecasts were produced.

Quarterly traffic compared to variation of port freight traffic

This analysis puts the fall of port freight volumes since the pandemic into the context of how much port freight traffic usually varies over time. The below graphs show tonnage and unitised quarterly traffic since 2015 plotted against a long-term linear trend estimated from 2009 to 2019 data (grey line). The area shaded in light green represents the range of values within 1 standard deviation from this trend. The area shaded in dark green represents the range of values within 2 standard deviations from the trend.

Up to 2019, unitised traffic has tended to remain within 1 standard deviation from the trend, with a very regular seasonal variation. Tonnage traffic has varied slightly more than unitised traffic over time around the long-term trend and does not follow a very regular seasonal pattern but has remained within the wider range of 2 standard deviations from the trend. As can be seen from the charts, figures for both tonnage and units fell far below historical variability in quarter 2 (April to June) 2020, showing the impact coronavirus and related effects of coronavirus (for example, on the economy) may have had on port freight traffic. Throughout the second half of 2021 and the first quarter (January to March) of 2022, units have followed the pre-pandemic quarterly pattern, but at a much lower level, fluctuating within and outside of 2 standard deviations below pre pandemic trends.

Note on method:

To calculate the ranges of standard deviation, the differences between the published quarterly port freight figures and the trend was calculated for each quarter and then squared. The sum of these squared differences, divided by the number of quarters minus 2, gives the expected variance. To obtain the standard deviation, the square root of this variance was performed. This standard deviation was then added and or subtracted from the trend to show the range of how much we might expect port traffic to vary over time around the trend.

Further information and definitions

Unitised goods:

Goods which are lifted on or off the vessel in large (20 foot or longer) shipping containers or rolled on or off in 1 of a variety of self-propelled or towed units are said to be unitised cargoes. For these cargo types, the number of units as well as the weight of goods is recorded. The exception is passenger cars, which don’t carry cargo and therefore we collect only the number of units.

Tonnage:

Gross weight in tonnes, including crates and other packaging. The tare weights of containers, road goods vehicles, trailers and other items of transport equipment (the unloaded weight of the vehicle or equipment itself) are excluded.

Reduction of the self-isolation period for travellers returning from non-travel corridor countries, from 14 to 10 days. Introduction of test to release to shorten the self-isolation period for international arrivals and varying Christmas travel guidelines across the UK.

Stricter tier 4 restrictions brought in for the South-East, after the discovery of a new variant. In response to this new variant, restrictions were brought in by other countries, that all individuals including freight drivers needed a negative COVID-19 test.

Passenger and accompanied freight travel to France was stopped completely for 2 days, accompanied freight travel was only allowed following this ban with the driver receiving a negative test within the last 72 hours.

First quarter: January to March 2021

National lockdown comes into force on 5 January for the duration of the first quarter of 2021. The UK advised against all international travel unless it is for a permitted exempt reason, with all travel corridors being suspended. Pre-departure testing requirements for all inbound passengers to England were introduced, with passengers having to take a test up to 3 days before departure and provide evidence of a negative result before they travel. All inbound international passengers required to take 2 mandatory COVID-19 tests on day 2 and 8 of their quarantine with those arriving from red list countries required to quarantine in managed quarantine facilities.

Second quarter: April to June 2021

Non-essential international travel resumed from Monday 17th May 2021, with the introduction of the country traffic light system (red, amber and green lists).

Third quarter: July to September 2021

From 2nd August, passengers arriving from amber list countries, and territories, who are fully vaccinated residents in the UK, Europe and US are no longer required to isolate on arrival but must complete mandatory COVID-19 test on or before day 2 after their arrival. Norway and other European countries added to the Government’s Green list for travel on 8th August.

Fourth Quarter: October to December 2021

October:

A new system of travel with countries identified as on “red list” and “rest of world” was implemented. Fully vaccinated travellers returning to England from “rest of world” countries (such as non “red list” countries) can replace day 2 PCR tests with lateral flow tests.

November:

In response to the omicron variant, fully vaccinated travellers returning to England from “rest of world” countries must self-isolate and take a PCR test before the end of day 2 after they arrive in England.

December:

All people aged 12 years and over must also take a PCR or lateral flow test before they travel to England from abroad. Similar rules also came in for travel to the rest of the UK.

In response to the omicron variant being widespread in the UK, all but essential travel from the UK to France was banned by the French Government.

First Quarter: January to March 2022 (this release)

January:

People who qualify as fully vaccinated for travel to England no longer need a pre-departure COVID test or quarantine on arrival. Similar easings were also made in Scotland. France allows fully vaccinated travellers to enter France without a compelling reason and fully vaccinated travellers to France are not required to self-isolate on arrival.

February:

Fully vaccinated passengers no longer need to take a COVID-19 test when arriving in the UK. France announces that fully vaccinated travellers from the United Kingdom are no longer required to take a pre-departure COVID test.

March:

All remaining UK travel restrictions end.
