In the first two years they can pretty much get rid of you for any reason (or even no reason!), so it's perhaps a bad idea to give them any excuse until the two years are up. Even then, establishing that say, you've been unfairly dismissed, is not always easy.
In the first two years I think you would be able to sue for "wrongful" (as opposed to "unfair") dismissal, but there you are talking about legal differences beyond my competence.
Is there a problem other than the lack of a written contract? You could ask again (tactfully). eg "Oh - I've just realised that I don't seem to have a copy of my terms and conditions. Can you let me have a copy?" If they keep refusing you might decide that either (1) there's something funny going on here, or (2) they're simply incompetent.
Assuming you pay tax and NI, you may want to check with HMRC that deductions are being paid over to them. (I assume you can do this without your employer knowing - others will know how).
Are you being paid for overtime worked?
as it is on a separate pole and not on the building the height is immaterial. the deemed consent requires the height to be no more than...... and they dont have that because it isnt attached to the building
Do not confuse the 2 things
yes please, go back to the very beginning to explain everything.
We will need to know what you put down in writing fro your defence as well as the info on the signage that is contested.
Did PE argue that the signage has chnaged since you entered the land and breached the contract or did they simply state that there were 5 signs when that is clearly not so?
appeals are on either matters of fact or matters of law so if you want to raies the planning issue then that is a matter of law (no contract can be formed) but not raising it earlier will make that a difficult ne to put forward.
It is unfortunately very common for PE and others to just tell out and out lies when it comes to signage etc so look up other cases where they ahve tried the same trick and use that as evidence if possible
