Why is it only yourself being made redundant? You need to make sure that this is done fairly and if you are in any doubt at all, take some legal advice. They do not have to offer you anything on top of statutory really. However you need to make sure that this is a real redundancy - if it is you personally they want out (and not the position) then you are in a better position for negotiating a fuss free exit in return for a more generous payment. Take some professional advice.
By the way, 6 weeks plus statutory would be considered extremely generous, 6 weeks including statutory is very good, and around 4 weeks per year is OK (IME)
