Heather, you'll be going to a County Court which deals with civil matters, not criminal. In fact, often these sort of cases are heard in the relative informality of the Judge's chambers rather than in the Court room.
In addition, as the plaintiff, I'd expect you to be looked after by the court staff. Also, you will have the choice of Court location to suit yourself
Even though you have been warned for Court, have you been given a date yet?
I'd be really surprised if it did see the inside of a Court as the costs for the losing party become astronomical and from what you've said it's clear you'll win. They tend to push it to see if you have the resolve to go through with the case.
Presumably, your people will use this extension of the time taken to settle to increase quantum of damages, which are usually based upon the length of time you've suffered physical and / or mental pain. I'd expect a new and reasonable offer to settle just before the case is to be heard. Even if it doesn't go the distance, they will be in line for significant costs in Court time for the preparation of the case.
