The claim is about the document, not a passage
People naturally send the part that answers the question they were asked: the line with the date on it, the paragraph naming the holder. A certified set does not work that way. The signature attaches to a named document and says the English matches it, so what was supplied defines what the claim covers. Anything held back quietly narrows a statement that was supposed to be about everything.
The language Gambia requires
English is what a document used in Gambia has to be readable in, and a certified translation in Leicester for Gambia supplies it for any page that is not already in English. The source keeps its own language and its own form throughout, and it is neither reissued nor amended. What you receive is an English companion to it, produced to be read alongside rather than instead.
What the signed statement covers
A dated certificate of accuracy, signed by a professional certified translator, identifies the document and confirms that the English corresponds to it. The wording is deliberately about a document rather than about a number of words, which is what makes completeness a matter of accuracy rather than of thoroughness. A Gambian reader is entitled to assume that nothing was quietly set aside.
Per-page cost and turnaround
Work runs at £25 a page, in 2–3 business days as standard or 24 hours express. Scanning the document entire before anything is quoted gives you a figure that will not move afterwards. The unwelcome version of this job is the one where a continuation sheet surfaces halfway through and the whole set has to be reopened to take it in.
