Hi - we've got a train-based holiday in Italy coming up which includes Interrail passes, and have been told to use them for the initial leg from Chippenham to London Paddington. The passes are marked 'class 1'. Might be a daft question, but can use them to travel first class on the GWR▸ service?

If they are global (all country) passes then yes, but remember that you get just two days
UK▸ - "inbound / outbound' is the intent - in your own country.
Chippenham - Paddington (1st Class), Elizabeth line to Farringdon, Thamelsink to St Pancras all included as (but with a "seat reservation" fee that feels more like a supplement) is Eurostar and provide you start all legs of the journey in the UK in the same day, it's just one day off your pass. Example - Lisa and I the other week, Melksham to Swindon to London and onward to Brussels and Frankfurt in a single day. 1st class included coffee and snack on GWR, and gets you standard premier on Eurostar which include our lunch.
