How do they know how much compensation on Advance 1st Class ticket when no 1st now available?

I understand that when a train for which you have bought a 1st Class ticket is substituted with a train that has no 1st Class provision, you are entitled to the difference in price.

However if you bought an Advance 1st Class ticket some while ago, how do they know how much the equivalent Standard Class ticket would have cost at the time of purchase?

I’m currently looking at a journey tomorrow on TfW, where if I bought a ticket today for the same service, the price of a Standard Class ticket is dearer than the 1st Class ticket I hold for that same journey.

Obviously hoping it doesn’t happen, but I see that today there was such a substitution, so I’m not confident it won’t happen tomorrow.

Each Advance tier has a specific code associated to it, so I assume they match the relevant First Class tier to the equivalent Standard Class one.

What was available at the time of purchase isn't relevant. They have equivalently coded first and standard advance tiers they use for comparison purposes.

Thanks both. I never knew that!

On TfW services it's fairly simple - their first class fares (including Advances) are all 50% more than the equivalent standard class fare. So you'll get that uplift back - it's equivalent to getting a 1/3 "discount".
