Which paper in the bundle needs the work
Most files put together in Leicester hold a mixture. Some pages were issued here and read in English already. Others arrived with their holder from another country: a birth entry, a school record, a marriage line, a court sheet. A certified translation for South Africa is aimed squarely at that second group, and the first group is left as it is.
This is worth sorting out early, because it changes both the price and the plan. A bundle of eight papers may hold only two that need anything done to them. Where an English record is wanted in a cleaner form, Leicester Registration Service at 115 Charles Street, Leicester LE1 1FZ issues certified copies of births, marriages and deaths registered in the city, which is a different job from translation.
The language South Africa requires
A certified translation into English in Leicester is required for a document that will be used in South Africa, whatever language that document was written in when it was issued. The English is what the reader there works from. Nothing is summarised on the way: every heading, entry and note that appears on the page is written out, so the two versions match each other page for page.
Certification South Africa accepts
What makes the English count is a certificate of accuracy — a dated sheet, signed by a certified translator, naming the document and stating that the English corresponds to it. A certified translation in Leicester for South Africa is therefore three things at once: the source page, the English, and the signature joining them. Split them up and the last of the three has nothing left to point at.
Per-page cost and turnaround
An official English translation in Leicester runs at £25 a page, counted on the pages that actually need writing. Standard turnaround is 2–3 business days from a clear scan and the express route closes in 24 hours. Because the work skips whatever is in English already, the count is often smaller than the size of the bundle suggests, and the date you can promise the office is nearer than you expect.
