Aless--where did you find the information on the breakdown, and the calculator?
I understand what a couple of you have said about certain things not being truly "essential," and I agree that people could survive on very little, however the question is should they have to? I think that this amount represents a standard of living that should be the minimum available to everyone. No one should have to struggle to support a family on less than £27,000 a year, unless perhaps their own irresponsibility and bad decision-making is responsible for their low income. DH and I make slightly more than this, and what with rent, council tax, bills, and saving for ILR, we don't have much breathing room. I doubt very much that we could afford a child. We do have a car, but DH's father technically owns it, and we need it for DH's commute. We don't really take holidays, we don't drink or smoke, and we don't go out much. I suppose we do spend rather a lot on food, but I am like Jewlz in that I really don't want to have to resort to eating nasty processed stuff all the time. But I firmly believe that everyone should have access to affordable housing and good quality healthy food, and no one should have to choose between those things and things like clothing, holidays, etc. If you work hard and don't live extravagantly, you should be able to afford those things. The fact that many people in that situation can't is a testament to the fact that cost of living is too high and salaries are too low. That's the big problem here.
