Question to the HM Treasury:

To ask His Majesty's Government what estimate they have made of the volume and value of trade passing through the ports of (1) Holyhead, and (2) Fishguard; and how these figures compare to corresponding figures from 2015.

The volume and value of trade passing through the ports of Holyhead and Fishguard in 2015 and 2024 (latest complete year of data) is as follows:

Source: HMRC Overseas Trade Statistics, uktradeinfo, compiled on 10^th September 2025

HM Revenue & Customs (HMRC) does not have port data prior to 2021 for EU trade as the UK was part of the European Union and customs declarations were not required for these movements. Trade data for intra-EU movements was collected via monthly Intrastat declarations which did not collect information on ports.
Figures for EU trade combine EU imports and EU exports. Similarly, figures for non-EU trade combine Non-EU imports and non-EU exports

The figures above exclude trade in low value consignments (namely imports and exports of an individual value of £873 or less) since HMRC does not have port data for trade in low value consignments.

Holyhead is primarily an EU facing port with no reported data for goods moving from/to non-EU countries in 2015.

The data provided covers goods that have been declared for import or export from either Holyhead or Fishguard but excludes data for goods entering Customs warehouses, freezones or freeports, and goods in transit (even when transhipment or temporary admissions are involved).

HM Revenue & Customs (HMRC) is responsible for the collection and publication of data on imports and exports of goods to and from the UK. HMRC releases this information monthly, as an accredited official statistic called the Overseas Trade in Goods Statistics (OTS), which is available via their dedicated website (www.uktradeinfo.com).
