There is none. None of the them have offices in the UK and those that have visit them first and they wont allow you. You can get genuine people at UK universities, say those doing their PhDs at your University. But they may charge quite more cos they are genuine good.

Hope this helps

I had paid £244 to

expertwritinghelp.co.uk
ukacademicexperts.co.uk/contact.html

They are one company. They charged me £900 and thank God, I happen not have such money on me. Just after I paid £244, communicating was very strange. I had wrong work sent and when I followed up, there was no response and messages were not answered. Watch out for these international fraud stars. Before the payment left my account, I called my bank to cancel and I was told the payment has already been approved and can only follow up after it leaves your account. Brilliant.

Good luck
