Well in my area (astrophysics) they seem to always have extra places for people who self-fund. Not that I've ever met any of them, it's a heck of a lot of money! As for funding, you might stand a chance of a funded place in some unis, and possibly stand a better chance of getting something at a foreign uni. I wouldn't count out a chance of a funded place somewhere if you're willing to be flexible with what you study, and you have plenty of experience/useful skills.

How realistic is it to get accpeted to a science PhD (self-funded, since I don 't think I stand a chance to get funding) with a low 2.1
Is your 2:1 in an an integrated Masters or a Bachelors. If it's in a Bachelors then it might be sensible to looks at a Masters degrees - a merit or distinction in a Masters would make you much more competitive.
Otherwise, as the above poster said, they do struggle to fill funded places with good candidates at some Universities - if you can get a good reference from your fourth year project supervisor you might find it's not as impossible to get funding as you think.
It's definitely not impossible, I have a friend who got onto a (self-funded) Masters course at Cambridge with a 2:2. I agree with Mbob though that it might be worth looking into a Masters first, especially if you would like to stay there to do your PhD - having references and contacts within the department itself would be a big advantage - they could also perhaps advise you on other funding sources. And if the person writing your reference is your potential PhD supervisor then that will look very good! Also I'm not sure what way it works with sciences, if you would be applying to a specific project, or putting in your own proposal, but if you are writing a proposal the key to getting funding is to make it a good one! Make sure your interests align with those of the department, make sure it is unique and show clearly how your research will add to that already existing in your chosen field.
A little late but science applicants who are willing to self fund stand a pretty good chance of being accepted; some may require you to do a masters before progressing to the PhD itself but it's still possible. Even more possible if it's an advertised opportunity or one which aligns very well with the research interests of various faculty members.
As others have said with a good reference someone with a 2.1 has a very good chance of getting funding, it's all about potential and whether those who'll be funding you can be convinced you'd make a better job of it than the other applicants. It's not always as simple as the grades you have.
