The team at Proofreading London is made up entirely of native English speakers. This may seem like a pointless claim to clients whose mother tongue is English, but when a client speaks English as a second language, this fact is paramount. Regardless of a proofreader's field of expertise, if that person is not a native speaker of English, it cannot be guaranteed that your text will be in perfect and fluent English. If the eventual recipient of your work is a native English speaker, they will expect a certain standard of writing, so make sure that your English meets their tough demands by ensuring that your English is flawless. The only way to guarantee this is by using a native speaking proofreader.
