At the start of this year I was using TPE's ticket booking system and app.
It is terrible. An incoherent mess. There is not enough time and sweary words to describe how horrible it is.

Then a month ago, @seabass tipped me off about TrainSplit, and I am now forever in their debt.

Trainspilt online, and in the app is how rail booking should be.
Clear, consistent, a range of filters if reqd, good info in the app whilst you're travelling, and unlike LNER, you can purchase more than one ticket at a time!

My favourite option is using Exclude Operators to ensure I never have to travel with #crosscuntry !!!

Thank you @seabass

European train travel from the UK regions | Buying tickets to connect with Eurostar

Advice on buying UK train tickets to London to connect with Eurostar, or how to use ferry links to reach mainland Europe by-passing London...

@h0m54r @jon #Trainsplit will sell a #CIV ticket online but you have to ask for station #LondonInternational (LNE) (not St Pancras Intl) and then use something like a "more ticket types" to avoid being given an less-protected more-expensive "London Terminals" ticket. You do have to show your #Eurostar ticket with it. This really should be easy and on all those platforms, especially with so few UK ticket offices left and those on shorter hours.
