Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, pursuant to the Answer of 18 February 2026 to Question 112225, whether he has made an estimate of the level of passthrough to consumers as a (a) cost increase per passenger ticket and (b) percentage increase in fares.

As set out in the Impact Assessment, any passthrough to consumers is expected to be modest. International evidence, including from the EU ETS, shows fare changes have generally been in the low single digit range.

The Government has not undertaken route level ferry fare or passenger ticket modelling for the UK ETS domestic maritime expansion, as operators’ commercial decisions, vessel utilisation and fare structures vary widely.
