I'm assuming that you are not getting far in the 'environmental field' as a BSc in Environment is too general. It is certainly a field where further study is required to make you more specialist, but there is a plethora of courses - so buyer be ware. You need to do your research - what area do you want top get into? - consultancy? if so what area?, environmental consultants employ a wide range of people with different backgrounds - botanists, engineers, water pollution specialists etc. What about emerging areas like renewable energy?
Environmental Data Services is a comprehensive website and there are listings of jobs - OK most in UK, but they'll give you an idea of what's asked for in certain roles. Once you have got an idea of the sector and role you may be aiming for you can then do your Masters research with your shopping list of requirements.

Edit - just seen your post re UU course, that seems largely on the money in termns of the skills development side of things.
