After one year you are entitled to redundancy (one week per year worked) plus any holidays owed, plus the notice required under your ciontract (you may or may not be required to work the notice period - his choice). I know, as I was made redundant last year after just over a year.
He must (should!) have given you a written notice of termination. If this states redundancy, he has to pay it! If he refuses to pay, you will win a court case. If it gives another reason, (eg theft, & you are innocent) then you can go for unfair dismissal - he would need to prove his claim.
