One word, two objects
People arrive at this asking for a certified document and mean one of two quite different things. A copy carries the weight of the office that holds the entry. A translation carries the weight of the person who wrote it and put their name under it. Both are real, both are ordered, and the letter in your hand almost never spells out which is wanted.
English is what Liberia reads
Papers used in Liberia are read in English, so a certified translation into English in Sheffield is what is being asked for whenever the record was issued in another language. That is the half of the question this page answers. The other half, the copy, is a separate order with a separate cost and a separate office behind it.
What the translator's certificate says
The statement attached to the English pages is short and does one job. It names the translator, gives the date, and says the English matches the sheets that were supplied. It makes no claim about the record itself, because that is the register's business and not the writer's. Reading those few lines tells you exactly how far the signature reaches.
Per-page cost and turnaround
Each page is £25, counted from the images before any writing starts. Standard work takes 2–3 business days and the express route lands inside 24 hours. Ordering the copy first and the English writing second keeps the queue moving, because a copy that turns up late holds up everything standing behind it.
