You can also travel to Dover by coach or train and take a ferry across and train it from there, might be cheaper than the Eurostar, but I am not sure it will be, to many places to try to get info.

This search site can help you for the English part, coach as well as train:

And to find the cheaper tickers by air, best when it is still some time away:
