So, um... I seem to be missing something, but what exactly is the problem with community service? Seriously, it's not bad, and it gives you something to put on a resume saying, "hey, I have experience doing ___, and was a nice enough guy to do it for free to help others". Always a good thing. On top of that, since when did a bit of hard work kill anyone? Have you never worked outside before? Is it really that bad to get out and do a bit of physical labor?
Hell, you might not even be doing physical labor. Community service doesn't always mean building a railroad; volunteering at an animal shelter is community service. Or you could help an old lady take care of her yard. They don't need to force you to do a specific thing either. Making it a requirement to continue on to higher education works just as well; that gives you years to figure out when and what you want to do to count towards your service.
I'll admit freely I'm American, so I'm not exactly up-to-date on British politics, and there might be something else going on here. That said, I don't see anything particularly wrong with this.
