When a company uses a UK address, regardless of whether it is just a postal box or an actual location, it immediately falls under the academic laws governing that land. In this case, the UK address removes the authority of these companies, to perform essay writing services for students since that has been prevented by the law already. Therefore, these companies can be prosecuted to the full extent and the students, will learn that there are consequences to pay for hiring writing services, regardless of the location of the writing company. Rules are rules, strictly adhere to these if you wish to keep your certification upon graduation. The minute you hire a writing service of any sort, you risk losing your diploma in the future. That is not a risk any student should be willing to take.
