I was just reading this forum and decided that I should post a note of caution about ukessays.com / oxbridgegraduates.com
I'm a student who also writes for ukessays.com and as far as I know the work they provide is a reasonable standard (at least what I write is!). They don't require that their writers are graduates, just that they are on track to achieve a 2:1 which for most students is okay as the writer is probably around the same standard that they are.

A friend of mine recently asked for advice on getting a top notch essay so I recommended oxbridgegraduates.com as this site was set up by ukessays.com and the site says that they provide "2:1 and 1st class essays by qualified graduates from Oxford and Cambridge universities". I thought that this was a better deal for him than uk essays as he would get a graduate to write his essay, rather than student like me, and he's also be guaranteed to get someone who had graduated from Oxbridge rather than a student or graduate of any old university or college.
I was very surprised when I saw my friend's order circulated to ukessays writers and checked with him that he did order from oxbridgegraduates - which he did. The order circulated to ukessays writers did not give any clue that it had been placed with oxbridge graduates and didn't stipulate that the writer must be a graduate or have been to Oxford or Cambridge - so, from the details circulated, any writer who had completed a few pieces of work with ukessays.com could request to take on the order even if, like me, they were not a graduate and had never stepped foot inside either Oxford or Cambridge universities.
It is of course possible that ukessays.com do make additional checks on the writers who 'bid' for the work to ensure that they fulfill the criteria promised on the oxbridgegraduates website (i.e. that the writers are Oxbridge graduates) - even though they don't ask the writers for this information in the circulated 'brief'. I am, however, peturbed that they are offering out this work to people who plainly are not graduates and have no connection to Oxbridge.
As ukessays offer work to their writers by subject specific mailing lists, it would not seem difficult for them to set up a mailing list of Oxbridge graduates so that orders made on the Oxbridgegraduates website were only offered to appropriately qualified writers. As an essay ordered from oxbridgegraduates is significantly more expensive than one ordered from ukessays, I think that consumers should seek additional assurances that they are getting what they are paying a premium for.
